Abstract

The present application relates to a housing assembly and a mobile terminal. In a housing assembly (100), the axis (1211) of a pin insertion hole (121) in a side portion (12) of a housing (10) is arranged in parallel and spaced apart from the axis (2011) of a sliding rod (201) in a pushing mechanism (200). A guide rod (20) comprises a rod body (21) and an eccentric portion (22), wherein the eccentric portion (22) is connected to the peripheral surface of one end of the rod body (21); the rod body (21) is fitted in the pin insertion hole (121) in a sliding manner; and the eccentric portion (22) is arranged facing a bearing portion (11) of the housing (10). When an insertion pin (1) pushes a first end (21a) of the rod body (21), the sliding rod (201) is jointly pushed by a second end (21b) of the rod body (21) and a first side (22a) of the eccentric portion (22), and since the insertion pin (1) and the sliding rod (201) are not concentric, the acting forces of the insertion pin (1) and the sliding rod (201) on the guide rod (20) are not collinear, thereby generating a moment of resistance that acts on the guide rod (20). Due to the presence of the moment of resistance, a second side (22b) of the eccentric portion (22) abuts against the bearing portion (11), and the bearing portion (11) generates a counteracting moment, opposite the moment of resistance, for the guide rod (20), such that the guide rod (20) can be easily pushed and the pushing mechanism (200) works reliably, so as to smoothly insert and pull out a card tray, thereby reducing the possibility of damage to a mainboard device by means of the guide rod (20) during a movement process. In addition, the card tray and the pin insertion hole (121) can satisfy the design of being centered in a thickness direction.

目前的移动终端(比如，平板电脑、手机)中，客户识别模块卡(Subscriber Identification Module，SIM)或存储卡通过卡托安装在移动终端的卡座插槽内，卡座上设有能够推出卡托的顶推机构。顶推机构包括可滑动的滑杆与可转动的曲柄，移动终端壳体具有供捅针***的捅针孔，将捅针***捅针孔，使滑杆移动进而推动曲柄摆动，曲柄将会推出卡托。In current mobile terminals (such as tablet computers, mobile phones), a Subscriber Identification Module (SIM) or memory card is installed in a card holder slot of the mobile terminal through a card tray, and the card holder is provided with a card holder capable of ejecting the card. push-up mechanism. The push mechanism includes a slidable slide bar and a rotatable crank. The mobile terminal housing has a pin hole for the pin to be inserted. Insert the pin into the pin hole to move the slide bar and push the crank to swing, and the crank will push out. Cato.
传统技术有两种移动终端壳体方案。第一种是捅针和滑杆直接接触的方案，通过将捅针***捅针孔，使捅针和滑杆直接接触，滑杆带动曲柄摆动以使曲柄推出卡托。第二种是捅针和滑杆间接接触的方案，在壳体的捅针孔内设有导杆，导杆的一端与滑杆的外端相对设置。通过将捅针***捅针孔，捅针推顶导杆使导杆推顶滑杆，滑杆带动曲柄摆动以使曲柄推出卡托。There are two mobile terminal housing solutions in the traditional technology. The first one is the direct contact between the needle and the sliding rod. By inserting the needle into the hole of the needle, the needle and the sliding rod are in direct contact, and the sliding rod drives the crank to swing to push the crank out of the tray. The second is the scheme of indirect contact between the needle and the sliding rod. A guide rod is arranged in the needle hole of the housing, and one end of the guide rod is opposite to the outer end of the sliding rod. By inserting the needle into the needle hole, the needle pushes the guide rod, so that the guide rod pushes the sliding rod, and the sliding rod drives the crank to swing to push the crank out of the card holder.
上述两种方案，为了能顺利地推动滑杆，捅针孔与滑杆必须同心设计。若两者不同心，滑杆(或导杆)有可能被顶偏位，造成插拔力过大而难以推动滑杆(或导杆)，甚至使主板或主板上的器件损伤，影响移动终端的正常使用。通常地，卡托与捅针孔要尽量满足在移动终端厚度方向居中的外观设计。由于捅针孔与滑杆同心设计，滑杆也要尽量在厚度方向居中，这样对主板堆叠要求比较高。In the above two schemes, in order to smoothly push the sliding rod, the pinhole and the sliding rod must be concentrically designed. If the two are not concentric, the sliding rod (or guide rod) may be displaced by the top, resulting in excessive insertion force and difficulty in pushing the sliding rod (or guide rod), and even damage to the main board or components on the main board, affecting the mobile terminal. normal use. Generally, the card tray and the pinhole should be designed to be centered in the thickness direction of the mobile terminal as much as possible. Due to the concentric design of the pinhole and the slide bar, the slide bar should also be centered in the thickness direction as much as possible, which requires higher stacking of the motherboard.

The casing includes a bearing portion and a side portion connected to the periphery of the bearing portion, the side portion has a pin hole, and the axis of the pin hole is arranged in parallel with the axis of the sliding rod in the push mechanism. The guide rod includes a rod body and an eccentric portion. The rod body is slidably assembled in the needle hole, the first end of the rod body is used for pushing the needle, and the second end of the rod body is used for abutting with the sliding rod; the eccentric part is connected to the outer peripheral surface of the second end of the rod body, and the eccentric part is The first side of the eccentric portion faces the same direction as the second end face of the rod body, and the second side of the eccentric portion faces the bearing portion. When the poke needle pushes the first end of the rod body, the second end of the rod body and the first side of the eccentric part push the sliding rod together, and the second side of the eccentric part abuts against the bearing part, so that the bearing part generates an opposite direction to the guide rod. torque.
其中，导杆中的偏心部相对杆体的轴线偏心设置，偏心部与杆体两者不同心。在导杆的杆体安装于捅针孔时，杆体的轴线与捅针孔的轴线共线。在捅针***捅针孔时，捅针的轴线与捅针孔的轴线共线。偏心部的第一侧是指偏心部上与杆体第二端同侧的一面。偏心部的第二侧是指导杆装配在捅针孔时偏心部朝向承载部的一侧。Wherein, the eccentric part in the guide rod is eccentrically arranged relative to the axis of the rod body, and the eccentric part and the rod body are not concentric. When the rod body of the guide rod is installed in the needle hole, the axis of the rod body is collinear with the axis of the needle hole. When the needle is inserted into the needle hole, the axis of the needle is collinear with the axis of the needle hole. The first side of the eccentric portion refers to the side of the eccentric portion on the same side as the second end of the rod body. The second side of the eccentric portion is the side of the eccentric portion facing the bearing portion when the guide rod is assembled in the needle hole.

The forces on the guide rods are not collinear, which creates a drag torque acting on the guide rods. Due to the existence of the resistance moment, the second side of the eccentric part will abut on the bearing part, and the bearing part will generate a counteracting moment on the guide rod opposite to the resistance moment, so as to offset part of the resistance moment, so that the guide rod can be easily pushed and pushed The mechanism works reliably, so that the card tray can be inserted and removed smoothly, and the possibility of damage to the main board device during the movement of the guide rod is reduced.

The cross-sectional shape of the hole is adapted so that the rod body can move in the axial direction of the needle hole. When the needle pushes the first end of the rod body, the guide rod can only move in the axial direction, so that the first end of the rod body and the second side of the eccentric part push the sliding rod together, and the second side of the eccentric part can be reliably pushed Abutting against the bearing portion, thereby generating a counteracting moment opposite to the resistance moment to counteract a part of the resistance moment. In addition, the rotation of the guide rod is avoided during the movement, which can reduce the possibility that the sealing ring moves relative to the guide rod and affects the waterproof effect.
结合第一方面至第一方面的第四种可能的实现方式中任一项，在第一方面的第五种可能的实现方式中，杆体在其中部至杆体的第二端之间且背对偏心部的一侧设有避让槽，这样在杆体被推入壳体内部时，内部器件只会进入到该避让槽区域，有效降低内部器件由于与杆体干涉而造成损伤的情况，提高导杆与内部器件的可靠性。With reference to any one of the first aspect to the fourth possible implementation manner of the first aspect, in a fifth possible implementation manner of the first aspect, the rod body is between the middle part and the second end of the rod body and faces away from There is an escape groove on one side of the eccentric part, so that when the rod body is pushed into the casing, the internal parts will only enter the escape groove area, which effectively reduces the damage caused by the interference of the internal parts with the rod body, and improves the relationship between the guide rod and the rod body. reliability of internal components.

The hardness is greater than the hardness of the eccentric part. The eccentric part can be made of soft material with certain elasticity. When the second side of the eccentric part is in contact with the bearing part, the eccentric part will generate a rebound force, and the rebound force will be transmitted to the user through the rod body and the needle, which can enhance the user experience. After the guide rod is reset to the needle hole, the elastic eccentric part will automatically recover.
结合第一方面至第一方面的第六种可能的实现方式中任一项，在第一方面的第九种可能的实现方式中，导杆中的偏心部为弹片，杆体以弹片为镶件通过模内注塑而成。本实施例中的偏心部以弹片作为镶件，这样偏心部的强度更大，可靠性更好。而且，弹片占用空间更小，偏心部结构紧凑，在滑杆的轴线与捅针孔的轴线的间距较大时，偏心部可实现较大的变形量以抵接于承载部表面，形成作用于导杆的抵消力矩，利于导杆顺滑移动。还有，弹片具有一定的弹性，这样用户在用捅针推顶导杆时会有弹性手感，增加用户体验。With reference to any one of the first to sixth possible implementations of the first aspect, in the ninth possible implementation of the first aspect, the eccentric part in the guide rod is a shrapnel, and the rod body uses the shrapnel as an insert Made by in-mold injection. The eccentric part in this embodiment uses the elastic sheet as the insert, so that the strength of the eccentric part is higher and the reliability is better. Moreover, the shrapnel occupies less space, and the eccentric part has a compact structure. When the distance between the axis of the sliding rod and the axis of the needle hole is large, the eccentric part can achieve a large amount of deformation to abut the surface of the bearing part, forming an effect on the surface of the bearing part. The counteracting moment of the guide rod is conducive to the smooth movement of the guide rod. In addition, the shrapnel has a certain elasticity, so that the user will have an elastic feel when pushing the guide rod with the needle, which increases the user experience.

The sliding bar 201 does not need to be centered in the thickness direction, which reduces the requirement for stacking the mainboard, and facilitates the arrangement of mainboard devices inside the housing 10 .
在装配导杆与壳体时，参阅图2、图3，当捅针1未***捅针孔121内时，偏心部22的第二侧22b与承载部11之间保持较小的缝隙，比如缝隙距离为0.05mm，具体缝隙距离不限定。这样在捅针1***捅针孔121内并推顶导杆20的第一端21a较小的位移时，就会在导杆20上形成一个阻力矩，在该阻力矩的作用下，导杆20的偏心部22就能容易地抵接在承载部11上，进而产生一个抵消力矩以抵消上述阻力矩，有利于导杆20顺利推动。When assembling the guide rod and the housing, referring to FIGS. 2 and 3 , when the needle 1 is not inserted into the needle hole 121, a small gap is maintained between the second side 22b of the eccentric portion 22 and the bearing portion 11, such as The gap distance is 0.05mm, and the specific gap distance is not limited. In this way, when the needle 1 is inserted into the needle hole 121 and the first end 21a of the guide rod 20 is pushed to a small displacement, a resistance torque will be formed on the guide rod 20. Under the action of the resistance torque, the guide rod The eccentric portion 22 of the 20 can easily abut on the bearing portion 11 , thereby generating a counteracting moment to counteract the above-mentioned resistance moment, which is beneficial to the smooth pushing of the guide rod 20 .
在一些实施例中，参阅图2、图3，为了实现导杆20与捅针孔121之间的防水密封，杆体21的第一端21a外周面套设有密封圈30，密封圈30的外径略大于捅针孔121的孔径，密封圈30的外周面与捅针孔121之间过盈配合。采用密封圈30可有效地实现导杆20外壁与捅针孔121内壁之间的间隙密封，降低外部液体由捅针孔121进入壳体10内部的可能性，提高内部主板和器件的可靠性。其中，密封圈30可以采用硅胶、橡胶等具有一定弹性的材料制作，还可采用注塑成型。将配有密封圈30的导杆20装配到捅针孔121内时，密封圈30将会挤压变形，实现导杆20与捅针孔121之间有效密封。In some embodiments, referring to FIGS. 2 and 3 , in order to achieve a waterproof seal between the guide rod 20 and the needle hole 121 , a sealing ring 30 is sleeved on the outer peripheral surface of the first end 21 a of the rod body 21 . The diameter is slightly larger than the hole diameter of the needle hole 121 , and there is an interference fit between the outer peripheral surface of the sealing ring 30 and the needle hole 121 . The sealing ring 30 can effectively seal the gap between the outer wall of the guide rod 20 and the inner wall of the needle hole 121, reduce the possibility of external liquid entering the casing 10 through the needle hole 121, and improve the reliability of the internal main board and devices. Wherein, the sealing ring 30 can be made of materials with certain elasticity such as silica gel, rubber, etc., and can also be made of injection molding. When the guide rod 20 equipped with the sealing ring 30 is assembled into the needle hole 121 , the sealing ring 30 will be squeezed and deformed to achieve effective sealing between the guide rod 20 and the needle hole 121 .
在一些实施例中，参阅图3，为了便于密封圈30限位安装在杆体21上，杆体21的第一端21a外周面具有安装槽211，密封圈30装配于安装槽211，这样在导杆20来回移动的过程中，密封圈30保持在安装槽211内，跟随导杆20移动，降低密封圈30脱离导杆20而导致密封失效的情况，提升密封可靠性。示例性的，安装槽211为环形槽，这样密封圈30套设在安装槽211上，即可对密封圈30进行限位。In some embodiments, referring to FIG. 3 , in order to facilitate the limited installation of the sealing ring 30 on the rod body 21 , the outer peripheral surface of the first end 21 a of the rod body 21 has an installation groove 211 , and the sealing ring 30 is assembled in the installation groove 211 . During the back and forth movement of the sealing ring 30, the sealing ring 30 is kept in the installation groove 211 and moves with the guide rod 20, which reduces the sealing failure caused by the separation of the sealing ring 30 from the guide rod 20, and improves the sealing reliability. Exemplarily, the installation groove 211 is an annular groove, so that the sealing ring 30 is sleeved on the installation groove 211 to limit the sealing ring 30 .
在一些实施例中，参阅图2，为了使配有密封圈30的导杆20能在捅针孔121内顺滑移动，密封圈30的表面设有润滑油，比如手感油。这样可降低密封圈30与捅针孔121内壁之间的摩擦力，便于配有密封圈30的导杆20装配到捅针孔121内，导杆20可在捅针孔121内顺滑移动，顶推机构200可靠工作，进而实现卡托400的顺利插拔。In some embodiments, referring to FIG. 2 , in order to enable the guide rod 20 equipped with the sealing ring 30 to move smoothly in the needle hole 121 , the surface of the sealing ring 30 is provided with lubricating oil, such as feel oil. In this way, the friction between the sealing ring 30 and the inner wall of the needle hole 121 can be reduced, so that the guide rod 20 equipped with the sealing ring 30 can be assembled into the needle hole 121, and the guide rod 20 can move smoothly in the needle hole 121. The pushing mechanism 200 works reliably, thereby realizing the smooth insertion and removal of the card tray 400 .
在具体设置捅针孔与杆体时，参阅图2，为了使导杆20只能沿轴向移动而不能转动，捅针孔121为异形孔，杆体21的横截面形状与捅针孔121的横截面形状相适配，杆体21的外径略小于或等于捅针孔121的配合孔径，以使杆体21能够沿捅针孔121的轴向移动。当捅针1推顶杆体21的第一端21a时，导杆20只能沿轴向移动，结合图3，使杆体21的第一端21a与偏心部22的第二侧22b共同推顶滑杆201，并使偏心部22的第二侧22b可靠地抵接于承载部11，从而产生一个与阻力矩反向的抵消力矩，以抵消一部分阻力矩。还有，避免导杆20在移动过程中转动，这样可降低密封圈30相对导杆20移动而影响防水效果的可能性。其中，异形孔是指除了圆形以外的孔形，比如菱形孔、方形孔、三角形孔、腰型孔。示例性的，捅针孔121的横截面呈跑道型，杆体21的横截面呈跑道型，在杆体21装配于捅针孔121时，杆体21只能沿捅针孔121轴向移动。When specifically setting the pin hole and the rod body, referring to FIG. 2 , in order to make the guide rod 20 move only in the axial direction but not rotate, the pin hole 121 is a special-shaped hole, and the cross-sectional shape of the rod body 21 is the same as the horizontal direction of the pin hole 121. The cross-sectional shape is adapted, and the outer diameter of the rod body 21 is slightly smaller than or equal to the matching diameter of the pin hole 121 , so that the rod body 21 can move along the axial direction of the pin hole 121 . When the needle 1 pushes the first end 21a of the rod body 21, the guide rod 20 can only move in the axial direction. With reference to FIG. rod 201, and make the second side 22b of the eccentric part 22 reliably abut against the bearing part 11, so as to generate a counteracting moment opposite to the resistance moment to counteract a part of the resistance moment. In addition, the rotation of the guide rod 20 is avoided during the movement process, which can reduce the possibility that the sealing ring 30 moves relative to the guide rod 20 and affects the waterproof effect. Among them, special-shaped holes refer to hole shapes other than circular, such as diamond-shaped holes, square holes, triangular holes, and waist-shaped holes. Exemplarily, the cross section of the pinhole 121 is a racetrack shape, and the cross section of the rod body 21 is a racetrack shape. When the rod body 21 is assembled in the pinhole 121 , the rod body 21 can only move axially along the pinhole 121 .
在一些实施例中，参阅图2、图3，为了在杆体21第二端21b被推入壳体10内部时不会跟壳体10内部器件发生干涉，杆体21在其中部至杆体21的第二端21b之间且背对偏心部22的一侧设有避让槽212，这样在杆体21被推入壳体10内部时，内部器件只会进入到该避让槽212区域，有效降低内部器件由于与杆体21干涉而造成损伤的情况，提高导杆20与内部器件的可靠性。示例性的，杆体21的第一端21a区域的横截面呈跑道型，杆体21在其中部至杆体21的第二端21b之间的区域的横截面呈半跑道型，即杆体21背对偏心部22的一侧设有避让槽212。In some embodiments, referring to FIG. 2 and FIG. 3 , in order to prevent interference with the internal components of the housing 10 when the second end 21b of the rod body 21 is pushed into the interior of the housing 10 , the rod body 21 is located from the middle of the rod body 21 to the first end of the rod body 21 . An escape groove 212 is provided between the two ends 21b and on the side facing away from the eccentric portion 22, so that when the rod body 21 is pushed into the casing 10, the internal components will only enter the area of the escape groove 212, which effectively reduces the In the case of interference with the rod body 21 to cause damage, the reliability of the guide rod 20 and the internal components is improved. Exemplarily, the cross section of the first end 21a of the rod body 21 is a racetrack shape, and the cross section of the region between the middle of the rod body 21 and the second end 21b of the rod body 21 is a semi-racetrack shape, that is, the rod body 21 faces away from the eccentricity. One side of the portion 22 is provided with an escape groove 212 .
在一些实施例中，参阅图3，为了提高具有避让槽212的杆体21的可靠性，杆体21的中部表面与避让槽212的表面之间具有光滑过渡面213，这样可有效降低杆体21由于避让槽212而形成的应力集中，降低插拔次数过多而造成杆体21断裂的情况。其 中，光滑过渡面213可以为圆弧面，这样容易成型，可降低应力集中情况。In some embodiments, referring to FIG. 3 , in order to improve the reliability of the rod body 21 with the avoidance groove 212 , a smooth transition surface 213 is provided between the middle surface of the rod body 21 and the surface of the avoidance groove 212 , which can effectively reduce the risk of the rod body 21 due to avoidance. The stress concentration formed by the groove 212 reduces the situation that the rod body 21 is broken due to excessive insertion and extraction times. The smooth transition surface 213 can be a circular arc surface, which is easy to form and can reduce stress concentration.
作为本申请的另一个实施例，针对捅针孔轴线和滑杆轴线距离较小的情况，参阅图3，导杆20中的杆体21与偏心部22为一体成型结构，比如采用一体注塑成型。杆体21与偏心部22采用一体成型结构，容易成型，便于批量生产。结合图2，为了便于偏心部22的注塑成型，偏心部22与杆体21的连接根部至偏心部22的第二侧22b的间距不能过大，否则难以注塑成型出偏心部22，因此，杆体21与偏心部22一体成型的方案适用于捅针孔轴线1211和滑杆轴线2011距离较小的情况。As another embodiment of the present application, for the case where the distance between the axis of the pin hole and the axis of the sliding rod is small, referring to FIG. 3 , the rod body 21 and the eccentric portion 22 in the guide rod 20 are integrally formed, such as by integral injection molding. The rod body 21 and the eccentric portion 22 adopt an integral molding structure, which is easy to shape and facilitates mass production. 2, in order to facilitate the injection molding of the eccentric portion 22, the distance from the connecting root of the eccentric portion 22 and the rod body 21 to the second side 22b of the eccentric portion 22 cannot be too large, otherwise it is difficult to injection-mold the eccentric portion 22. Therefore, the rod body 21 The solution integrated with the eccentric portion 22 is suitable for the case where the distance between the axis 1211 of the pin hole and the axis 2011 of the sliding rod is small.
作为本申请的另一个实施例，为了使杆体与偏心部具有不同的硬度，参阅图5、图6，导杆20中的杆体21与偏心部22通过双色注塑而成，杆体21的硬度大于偏心部22的硬度。偏心部22可采用具有一定弹性的软质材料制作，比如热塑性聚氨酯弹性体橡胶(Thermoplastic polyurethanes，TPU)，当然还可以采用其它软胶材料制作。在偏心部22的第二侧22b与承载部11接触时，偏心部22将会产生反弹力，反弹力通过杆体21与捅针1传递给用户，这样可增强用户体验。在导杆20杆体21复位至捅针孔121后，弹性的偏心部22将会自动复原。As another embodiment of the present application, in order to make the rod body and the eccentric part have different hardnesses, referring to FIGS. 5 and 6 , the rod body 21 and the eccentric part 22 in the guide rod 20 are formed by two-color injection molding, and the hardness of the rod body 21 is greater than that of the eccentric part. hardness of the part 22 . The eccentric portion 22 can be made of a soft material with certain elasticity, such as thermoplastic polyurethane elastomer rubber (Thermoplastic polyurethanes, TPU), and of course can also be made of other soft materials. When the second side 22b of the eccentric portion 22 is in contact with the bearing portion 11, the eccentric portion 22 will generate a rebound force, which is transmitted to the user through the rod body 21 and the needle 1, which can enhance user experience. After the rod body 21 of the guide rod 20 is reset to the needle hole 121, the elastic eccentric portion 22 will automatically reset.
示例性的，参阅图6，偏心部22具有连接杆221，杆体21具有连接孔214，在双色注塑时，连接杆221与连接孔214内壁紧密连接，这样提高偏心部22与杆体21之间连接的可靠性，降低导杆20在多次移动后偏心部22脱离杆体21的可能性。6, the eccentric portion 22 has a connecting rod 221, and the rod body 21 has a connecting hole 214. During two-color injection molding, the connecting rod 221 is tightly connected with the inner wall of the connecting hole 214, so as to improve the connection between the eccentric portion 22 and the rod body 21. This reduces the possibility of the eccentric portion 22 detaching from the rod body 21 after the guide rod 20 moves for many times.

Referring to FIG. 8 , in this embodiment, the eccentric portion 22 of the guide rod 20 is an elastic sheet, and the rod body 21 is formed by in-mold injection molding with the elastic sheet as an insert. In the case where the distance between the surface of the bearing portion 11 and the axis of the rod body 21 is relatively large, compared with the injection molding method of the eccentric portion, the eccentric portion 22 in this embodiment uses an elastic sheet as an insert, so that the strength of the eccentric portion 22 is greater. , the reliability is better, and it overcomes the situation that the guide rod is easy to break during use when the injection molding eccentric part is used. Moreover, the shrapnel occupies less space, and the eccentric portion 22 has a compact structure. When the distance between the axis 2011 of the sliding rod 201 and the axis 1211 of the pin hole 121 is large, the eccentric portion 22 can achieve a large amount of deformation to abut against the bearing The surface of the part 11 forms a counteracting moment acting on the guide rod 20, which is beneficial to the smooth movement of the guide rod 20. In addition, the shrapnel has a certain elasticity, so that the user will have an elastic feel when pushing the guide rod 20 with the needle 1, which increases the user experience. Wherein, the shrapnel can be a shrapnel made of steel sheet or other elastic materials.
示例性的，弹片具有弯折部和连接部，连接部的一端与弯折部的一端连接。将弹片放入模具内进行模内注塑，连接部与杆体21紧密连接，弯折部的端部与杆体21连接，这样弯折部具有一定弹性，可与承载部11抵接产生弹性变形，偏心部22可实现较大的变形量，形成对导杆20的抵消力矩，进而利于导杆20顺滑移动。Exemplarily, the elastic sheet has a bending part and a connecting part, and one end of the connecting part is connected with one end of the bending part. Put the shrapnel into the mold for in-mold injection molding, the connecting part is closely connected with the rod body 21, and the end of the bending part is connected with the rod body 21, so that the bending part has a certain elasticity, and can abut with the bearing part 11 to produce elastic deformation, eccentricity The portion 22 can achieve a large amount of deformation to form a counteracting moment to the guide rod 20 , thereby facilitating the smooth movement of the guide rod 20 .
