Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 and 2, in one embodiment, there is provided a roll brush assembly 10 including a rotating shaft 100 and a wiper strip 200.

It should be noted that the rolling brush assembly 10 of the present invention can be applied to various apparatuses or devices with cleaning functions, for example, as shown in fig. 1, can be applied to a robot including both sweeping and cleaning functions, a cleaning robot with a single cleaning function, and a handheld cleaning vacuum cleaner.

As shown in fig. 2, wherein the wiper strip 200 is provided on the rotating shaft 100. As such, when the rotating shaft 100 rotates, the wiper strip 200 can be driven to rotate along the rotating direction of the rotating shaft 100 around the central axis of the rotating shaft 100, and thus the cleaning surface can be cleaned.

It can be understood that the rotation of the rotation shaft 100 can be driven by a rotation driving component such as a motor, and the rotation driving component can be installed on the machine body, and can also rotate by rubbing with the ground during pushing, which belongs to the prior art and is not described herein again.

Specifically, the wiper strip 200 includes a ground portion 210 and a back ground portion 220.

The grounding portion 210 and the back grounding portion 220 both extend radially along the rotation axis 100 to be connected to each other, that is, along the rotation axis 100, the grounding portion 210 and the back grounding portion 220 both extend in a direction away from the rotation axis 100 until the grounding portion 210 and the back grounding portion 220 are connected to each other at a certain position.

It is understood that the ground portion 210 may refer to a portion of the wiper strip 200 that can contact the cleaning surface during rotation; the grounding portion 210 may be a side of the wiper strip 200 that can contact the cleaning surface during rotation, in which case, only a part of the grounding portion 210 may contact the cleaning surface, and the rest may not contact the cleaning surface.

The ground portion 210 and the back portion 220 may be connected to each other directly or indirectly with an intermediate element.

As shown in fig. 2 and 4, at least a part of the ground portion 210 and at least a part of the back ground portion 220 surround the rotary shaft 100 to form a deformation chamber 230.

It should be understood that, for the grounding portion 210, a part of the grounding portion 210 may participate in the enclosure of the deformable cavity 230 while another part of the grounding portion 210 does not participate in the enclosure of the deformable cavity 230, or all of the grounding portion 210 may participate in the enclosure of the deformable cavity 230. Similarly, for the back ground portion 220, a part of the back ground portion 220 may participate in the enclosure of the deformable cavity 230, while another part of the back ground portion 220 does not participate in the enclosure of the deformable cavity 230, or all of the back ground portion 220 may participate in the enclosure of the deformable cavity 230.

Alternatively, the ground portion 210 and the back ground portion 220 may be two opposite sidewalls of the deformation chamber 230, for example, a left sidewall and a right sidewall.

Specifically, in the embodiment of the present application, one end of the ground portion 210 and one end of the back portion 220 are respectively disposed on the rotating shaft 100, and the other end of the ground portion 210 and the other end of the back portion 220 are connected to each other, so that the wiper strip 200 and the rotating shaft 100 enclose the deformation cavity 230, that is, all of the ground portion 210, all of the back portion 220 and the rotating shaft 100 jointly enclose the deformation cavity 230. So set up, the size of deformation chamber 230 can be as big as possible, guarantees that grounding portion 210 has sufficient deformation space and takes place deformation by a larger margin to can exert bigger flap power to the cleaning surface, it is better to the effect of raising of dust, better assurance cleaning performance.

Wherein, the connection of one end and the axis of rotation 100 of earthing portion 210 and the connection of one end and axis of rotation 100 of back of the body portion 220 all can take forms such as grafting, joint, only need satisfy can be with scraping the strip 200 stable, reliable installation on the lateral wall of axis of rotation 100 and make scraping the strip 200 can rotate along with axis of rotation 100.

Specifically, in the embodiment of the present application, as shown in fig. 4 and 5, the fastening portion 240 is disposed at one end of the grounding portion 210 and one end of the back portion 220; as shown in fig. 3, the circumferential outer side wall of the rotating shaft 100 is provided with a recess 110 that engages with the catch 240. In this way, the assembly connection between the wiper strip 200 and the rotating shaft 100 can be realized only by connecting the fastening portion 240 at one end of the grounding portion 210 and the fastening portion 240 at one end of the back portion 220 with the corresponding concave portion 110 on the circumferential outer side wall of the rotating shaft 100, which is simple and convenient and has high assembly efficiency. In addition, the scraping strips 200 can not be loosened relative to the rotating shaft 100 in the rotating process of the rotating shaft 100, and the connection is stable and reliable.

More specifically, the recess 110 extends in the axial direction of the rotating shaft 100, and the catch 240 is slidably fitted with the recess 110 in the axial direction of the rotating shaft 100. The scraper bar 200 is pushed by aligning the catching portion 240 with the recess 110 at the end of the rotating shaft 100, and the catching portion 240 is inserted into the recess 110 by the sliding fit of the catching portion 240 with the recess 110 until the whole catching portion 240 is fitted into the recess 110, thereby achieving the fitting connection of the scraper bar 200 with the rotating shaft 100. When the wiper strip 200 needs to be replaced, the engaging portion 240 is simply pulled out from the recess 110 from the end of the rotating shaft 100, which is convenient to assemble and disassemble.

The recess 110 extends in the axial direction of the rotating shaft 100, and means that the recess 110 extends to the end of the rotating shaft 100 in the axial direction of the rotating shaft 100.

Further, the extending locus of the concave portion 110 in the axial direction of the rotating shaft 100 may be matched to the extending locus of the wiper strip 200 in the axial direction of the rotating shaft 100.

The concave portion 110 may be a groove structure, and the locking portion 240 may be a connector structure adapted to the concave portion 110. In particular to the embodiment of the present application, as shown in fig. 3, the recess 110 is provided as a T-shaped groove 111; as shown in fig. 4, the locking portion 240 is a T-shaped connector 241 slidably engaged with the T-shaped groove 111. So, only need insert T-shaped connector 241 from the tip of axis of rotation 100 in T-slot 111, can realize scraping the assembly connection of strip 200 and axis of rotation 100 to, T-shaped connector 241 is big with the area of contact in T-slot 111, can effectively guarantee to scrape strip 200 and axis of rotation 100 assembly connection's stability and reliability, avoids the pine to take off.

In addition, in order to prevent the scraper bar 200 from falling off from the rotating shaft 100 during the rotation process, the rolling brush assembly 10 further includes a limiting member (not shown). Specifically, the stopper is used to block the wiper strip 200 from sliding out of the rotation shaft 100. Therefore, the limiting effect of the limiting piece on the scraping strip 200 is utilized, so that the scraping strip 200 is prevented from axially moving relative to the rotating shaft 100, and the scraping strip 200 is prevented from sliding out from the end part of the rotating shaft 100 in the rotating process of the rotating shaft 100.

More specifically, after the T-shaped connector 241 is completely inserted into the T-shaped groove 111 along the axial direction of the rotating shaft 100, the stopper acts on the scraping bar 200, so that the scraping bar 200 can be limited from moving along the axial direction of the rotating shaft 100, the reliability and stability of the assembly of the scraping bar 200 and the rotating shaft 100 are ensured, and relative falling is avoided.

In some embodiments, the limiting member is not detachable after being installed in order to ensure the blocking effect of the limiting member on the wiper strip 200. In other embodiments, the limiting member may be detachably connected to the rotating shaft 100 so as not to affect the mounting and dismounting of the wiper strip 200. Of course, the limiting member and the mounting bracket of the rotating shaft 100 may be detachably connected.

The limiting member may be an end cap, and the end cap may be detachably connected to the rotation shaft 100 or the mounting bracket of the rotation shaft 100 by means of clamping, inserting, or screwing. The limiting member may also be in the form of a limiting stopper or a limiting baffle, and only needs to be able to limit the scraping bar 200 from sliding out of the rotating shaft 100.

For convenience of explanation of the principle of the embodiment of the present application, the cleaning of the floor surface and other parts when the rotating shaft 100 rotates clockwise (as shown in the direction a of fig. 2) will be described as an example, and the embodiment of the present application is not to be construed as being limited thereto. In other embodiments, the rotating shaft 100 may also rotate in a counterclockwise direction to clean a cleaning surface such as a floor, and the rotating shaft 100 may also rotate in both a clockwise direction and a counterclockwise direction to clean the cleaning surface.

The rolling brush assembly 10 of the above embodiment drives the wiper strip 200 to rotate in the clockwise direction when the rotating shaft 100 rotates in the clockwise direction, and can flap the cleaning surface when the wiper strip 200 rotates to make the grounding portion 210 contact with the cleaning surface, so that dust on the cleaning surface can be lifted. As the grounding portion 210 comes into contact with the cleaning surface, the grounding portion 210 is pressed by the cleaning surface and elastically deformed in a direction approaching the deforming cavity 230. With the further rotation of the rotating shaft 100 in the clockwise direction, the wiper strip 200 is synchronously driven to further rotate in the clockwise direction, when the wiper strip 200 rotates to separate the grounding portion 210 from the cleaning surface, the grounding portion 210 elastically resets towards the direction away from the deformation cavity 230, that is, the grounding portion 210 rebounds towards the direction away from the deformation cavity 230, the deformation cavity 230 allows a moving space for the deformation and the resetting of the grounding portion 210, and the grounding portion 210 contacts with the cleaning surface again under the action of the rebounding force, so that the dust on the cleaning surface is further lifted. As can be seen from the above, a single rotation of the wiper strip 200 can make the grounding portion 210 contact with the cleaning surface at least twice, and perform flapping on the cleaning surface at least twice, so as to raise the dust on the cleaning surface better, facilitate cleaning of the dust, and achieve better cleaning effect.

Further, as shown in fig. 7 and 8, the grounding portion 210 has a first side 211 and a second side 212 opposite to each other in the rotational direction. Wherein the first side 211 is disposed adjacent to the rotation axis 100 relative to the second side 212. As shown in fig. 7, when the bar 200 rotates to make the first side 211 contact with the cleaning surface first to flap the cleaning surface, the second side 212 is separated from the cleaning surface, and when the bar 200 rotates to make the first side 211 separate from the cleaning surface, the first side 211 rebounds to flap the cleaning surface; as shown in fig. 8, as the scraper bar 200 continues to rotate, the second side 212 contacts with the cleaning surface to flap and raise dust on the cleaning surface, at this time, the first side 211 is separated from the cleaning surface, and when the scraper bar 200 rotates to separate the second side 212 from the cleaning surface, the second side 212 rebounds and flaps and raise dust on the cleaning surface; circulating like this, can making each position homoenergetic in grounding portion 210 can carry out twice to the cleaning surface and pat the ash that raises, raise grey effectual, promoted clean effect.

Meanwhile, when the grounding portion 210 is in contact with the cleaning surface, the grounding portion 210 deforms in the direction close to the deformation cavity 230, so that the profile of the deformation cavity 230 deforms, and the impact force and the extrusion force can be buffered and absorbed, not only can the impact on the cleaning surface be reduced, the abnormal sound generated by the roller brush assembly 10 and the cleaning surface be reduced, but also the abrasion of the cleaning surface can be avoided, and the deformation of the deformation cavity 230 is used for buffering and absorbing the impact force and the extrusion force, the impact force on the rotating shaft 100 can be reduced, the rotating shaft 100 is prevented from being subjected to a large radial load, the abrasion of the rotating shaft 100 is slowed down, and the rotating shaft 100 can be prevented from generating noise due to radial play.

Furthermore, when the grounding portion 210 deforms toward the direction approaching the deformable cavity 230, the back portion 220 also deforms accordingly, and the connection between the grounding portion 210 and the back portion 220 also deforms toward the direction away from the cleaning surface accordingly, so that when the grounding portion 210 is separated from the cleaning surface, the back portion 220 and the connection between the grounding portion 210 and the back portion 220 apply a resilient force toward the direction approaching the cleaning surface to the grounding portion 210, and further the resilient force of the grounding portion 210 toward the direction away from the deformable cavity 230 is increased, so that the cleaning surface is more strongly beaten, the dusting effect is better, and the cleaning effect is more favorably enhanced.

The scraping strip 200 may be made of an elastic material or a flexible material.

Specifically, the wiper strip 200 may be made of rubber, silica gel, or the like. Thus, when grounding portion 210 contacts with the cleaning surface, it is more favorable for grounding portion 210 to deform toward the direction approaching deformation cavity 230, and the deformation amplitude of grounding portion 210 is larger, so that when grounding portion 210 is separated from the cleaning surface, the deformation amplitude of grounding portion 210 toward the direction away from deformation cavity 230 is larger, and larger resilience can be applied to flap the cleaning surface, so that the dust raising effect is better, and the cleaning effect is more favorable for enhancing.

In addition, the scraping strip 200 is made of elastic materials or flexible materials, so that the deformation amplitude of the deformation cavity 230 is larger, impact force and extrusion force can be better buffered and absorbed, impact on a cleaning surface can be better reduced, abnormal sound generated by the rolling brush assembly 10 and the cleaning surface can be reduced, abrasion on the cleaning surface can be avoided, impact force on the rotating shaft 100 can be more effectively reduced, the rotating shaft 100 is prevented from being subjected to larger radial load, abrasion on the rotating shaft 100 is reduced, and noise generated by radial play of the rotating shaft 100 can be more effectively avoided; moreover, when the scraping bar 200 rotates, the hair can be better separated from the scraping bar 200, the problem of hair winding cannot occur, and the cleaning effect cannot be influenced.

Meanwhile, the scraping strip 200 is made of elastic materials or flexible materials, so that the whole scraping strip 200 is easy to reset to an initial position and an initial state after being deformed, and cannot be deformed in long-time use, and the service life is prolonged.

Further, the wiper strip 200 may extend in the axial direction of the rotary shaft 100, i.e., the wiper strip 200 may extend from one end of the rotary shaft 100 to the other end of the rotary shaft 100. Moreover, the extending track of the scraper bar 200 along the axial direction of the rotating shaft 100 may be a linear track or a curved track, and the specific extending track may be flexibly designed or adjusted according to the actual use requirement, which is not limited herein. For example, the extension track of the scraper bar 200 along the axial direction of the rotating shaft 100 may be V-shaped, so that dust can be better gathered towards the middle, the dust can be collected conveniently, and the cleaning effect can be improved.

The shape of the cross-sectional profile of the deformation cavity 230 can be flexibly designed or adjusted according to actual use requirements, and only the requirement that the grounding portion 210 can deform toward the direction close to the deformation cavity 230 when being squeezed by the cleaning surface, and can rebound toward the direction away from the deformation cavity 230 to flap the cleaning surface when the grounding portion 210 is separated from the cleaning surface is met, which is not limited herein. For example, the cross-sectional profile shape of deformable cavity 230 may be at least one of triangular, isosceles trapezoid-like, drop-shaped, V-shaped, U-shaped, circular, and elliptical.

It will be appreciated that the cross-sectional profile of the deformation chamber 230 refers to the profile that is defined transversely to the sidewall profile of the deformation chamber 230.

In addition, in order to effectively clean the dirt, considering that the dirt is also adhered to the cleaning surface, as shown in fig. 2 and 4, the bar 200 may further include a protrusion 250 provided at the back of the bar 200. So, scrape strip 200 and rotate the in-process, bellying 250 can with clean the face contact to can utilize bellying 250 to scrape the dirty of adhesion on cleaning the face, be convenient for clear up dirty, promote clean effect.

It is understood that the back of the wiper strip 200 may be the side of the wiper strip 200 away from the rotational shaft 100.

As shown in fig. 4, a protrusion 250 is further provided at a connection between the grounding portion 210 and the back grounding portion 220. The ground portion 210 and the back portion 220 are symmetrically disposed with respect to the protrusion portion 250. Therefore, the grounding part 210 and the back part 220 are symmetrically distributed on two sides of the protruding part 250, so that the protruding part 250 can effectively contact with a cleaning surface to scrape off dirt, and meanwhile, the protruding part 250 does not influence the deformation of the grounding part 210 towards the deformation cavity 230.

The cross-sectional shape of the protrusion 250 may be V-shaped, U-shaped, or other structures capable of scraping off the dirt adhered to the cleaning surface.

In particular, in the embodiment of the present application, the thickness of the protrusion 250 (as shown in dimension B of fig. 4) decreases in a direction away from the rotation axis 100, so that the protrusion 250 has a blade-like structure, and thus has a better effect of scraping off the dirt adhered to the cleaning surface.

In addition, the number of the wiper strips 200 can be flexibly adjusted or selected according to the cleaning requirement during the actual use.

Specifically, the wiper strip 200 is at least two. As shown in fig. 2, three wiper strips 200 are disposed on the rotating shaft 100 and distributed along the circumferential direction of the rotating shaft 100. The back portions 220 and the ground portions 210 of two adjacent wiper strips 200 are provided adjacent to each other. Thus, with the rotation of the rotating shaft 100, the grounding portion 210 of each wiper strip 200 can periodically flap the cleaning surface for cleaning, so as to effectively lift up the dust and achieve better cleaning effect on the cleaning surface.

In another embodiment, another roll brush assembly 10 is provided, which includes a rotating shaft 100 and a wiper strip 200.

As shown in fig. 6, the wiper strip 200 encloses a deformation chamber 230, i.e. the wiper strip 200 itself can enclose the complete deformation chamber 230.

Specifically, the wiper strip 200 is provided with a connecting portion, and the rotating shaft 100 is provided with a stopper portion fitted to the connecting portion, so that the wiper strip 200 is fitted to the rotating shaft 100 through the connecting portion.

It can be understood that the adaptation of the connecting portion and the limiting portion can be realized through clamping, inserting and the like, and only the requirement that the scraping strip 200 can be stably and reliably assembled on the rotating shaft 100 is met.

Specifically, the fitting between the connecting portion and the limiting portion may be the form of the engagement between the buckling portion 240 and the concave portion 110, which is not described herein again.

The rolling brush assembly 10 of the above embodiment drives the scraping bar 200 to rotate in the clockwise direction when the rotating shaft 100 rotates in the clockwise direction, and can flap the cleaning surface when one of the side walls of the scraping bar 200 rotates to contact with the cleaning surface, so that dust on the cleaning surface can be lifted. As the sidewall contacts the cleaning surface, the sidewall is pressed by the cleaning surface and elastically deformed toward the deforming cavity 230. With the further rotation of the rotating shaft 100 in the clockwise direction, the scraper bar 200 is synchronously driven to further rotate in the clockwise direction, when the scraper bar 200 rotates to separate the side wall from the cleaning surface, the side wall elastically resets towards the direction away from the deformation cavity 230, that is, the side wall rebounds towards the direction away from the deformation cavity 230, there is a moving space for the deformation and the resetting of the side wall by the deformation cavity 230, and the side wall contacts with the cleaning surface again under the action of the rebounding force, so that the dust on the cleaning surface is further lifted. From the above, the single rotation of the scraping strip 200 can make the side wall contact with the cleaning surface at least twice, and beat the cleaning surface at least twice, so that the dust on the cleaning surface can be better raised, the dust can be cleaned conveniently, and the cleaning effect is better.

It is understood that one of the side walls of the wiper strip 200 that contacts the cleaning surface may be the grounding portion 210.

As shown in fig. 5, in one embodiment, there is also provided a wiper strip 200, the wiper strip 200 including a ground portion 210 and a back ground portion 220.

Wherein the ground portion 210 and the back ground portion 220 are connected to each other. Also, the wiper strip 200 is configured to allow the grounding portion 210 and the back portion 220 to be bent to each other, so that the grounding portion 210 and the back portion 220 define at least a partial boundary of the deformable cavity 230, i.e., after the grounding portion 210 and the back portion 220 are connected to each other, the grounding portion 210 and the back portion 220 serve as at least a partial sidewall of the deformable cavity 230.

It will be appreciated that the boundary of the deformable cavity 230 refers to the contour that the side walls of the deformable cavity 230 enclose. The ground portion 210 and the back portion 220 define at least a partial boundary of the deformable cavity 230, and as shown in fig. 2, the deformable cavity 230 may be partially defined by the ground portion 210 and the back portion 220, that is, the ground portion 210 and the back portion 220 define a partial outline of the deformable cavity 230, and the remaining boundary of the deformable cavity 230 may be defined by other members. For example, when the wiper strip 200 is connected to the rotating shaft 100, the wiper strip 200 and the rotating shaft 100 define the boundary of the deformable cavity 230.

In other embodiments, as shown in fig. 6, it is understood that the deformation chamber 230 may also be formed within the wiper strip 200 itself. At this time, the cross section of the bar 200 assumes a closed ring structure. The cross section profile can be triangle, isosceles trapezoid, drop, circular,

Circular, etc. The land portion 210 and the back land portion 220 serve as a portion of the wiper strip 200, and define the boundary of the deformable cavity 230 together with the rest of the wiper strip 200.

The states of the wiper strip 200 before and after the assembly connection with the rotary shaft 100 may be the same or different. For convenience of explanation, the wiper strip 200 of the above embodiment is defined as a natural state when not assembled with the rotating shaft 100, and as an assembled state when assembled with the rotating shaft 100. The natural state and the assembled state of the wiper strip can exist in different forms.

For example, as shown in fig. 5, when the wiper strip 200 is in a natural state, the grounding portion 210 and the grounding portion 220 are in the same plane, and at this time, the grounding portion 210 and the grounding portion 220 may be considered to have a first predetermined included angle, where the first predetermined included angle is 0 ° or close to 0 °; when the wiper strip 200 is in the assembled state, as shown in fig. 4, the grounding portion 210 and the ground portion 220 are bent to form a second predetermined angle α, so that the grounding portion 210 and the ground portion 220 define at least a partial boundary of the deformable cavity 230.

In other alternative embodiments, the first predetermined angle may be equal to the second predetermined angle, i.e. the wiper strip 200 is in the same state in both the natural state and the assembled state; the first predetermined angle may also be greater than the second predetermined angle, that is, the grounding portion 210 and the back portion 220 are close to each other when the wiper strip 200 is changed to the assembly state in the natural state; the first predetermined angle may be smaller than the second predetermined angle, that is, the grounding portion 210 and the back portion 220 are away from each other when the wiper strip 200 is changed to the assembling state in the natural state.

The "certain body" and the "certain portion" may be a part corresponding to the "member", that is, the "certain body" and the "certain portion" may be integrally formed with the other part of the "member"; the "part" can be made separately from the "other part" and then combined with the "other part" into a whole. The expressions "a certain part" and "a certain part" in the present application are only one embodiment, and are not intended to limit the scope of the present application for reading convenience, and should be construed as equivalents of the present application as long as the features are included and the effects are the same.

It should be noted that, the components included in the "unit", "assembly", "mechanism" and "apparatus" of the present application can also be flexibly combined, i.e. can be produced in a modularized manner according to actual needs, so as to facilitate the modularized assembly. The division of the above-mentioned components in the present application is only one example, which is convenient for reading and is not a limitation to the protection scope of the present application, and the same functions as the above-mentioned components should be understood as equivalent technical solutions in the present application.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to," "disposed on," "secured to," or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Further, when one element is regarded as "fixed transmission connection" another element, the two elements may be fixed in a detachable connection manner or in a non-detachable connection manner, and power transmission can be realized, such as sleeving, clamping, integrally-formed fixing, welding and the like, which can be realized in the prior art, and is not burdensome. When an element is perpendicular or nearly perpendicular to another element, it is desirable that the two elements are perpendicular, but some vertical error may exist due to manufacturing and assembly effects.
