Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings, such as FIGS. 1-9:
because each tool bit part in the existing multi-tool bit assembly can realize reciprocating swing only by relying on the driving of two swinging parts, the swinging parts are connected with a power source (which can also be regarded as an output shaft of a driving motor and is not shown in the drawing), the transmission structure of the pruning tool is relatively complicated, and the production cost is higher. Therefore, the invention provides a single-drive multi-cutter-head assembly, which can realize reciprocating swinging by directly utilizing the driving of a power source without a swinging part, and comprises at least two cutter head parts 1 arranged side by side, wherein a linkage part 2 is arranged between the cutter head parts 1 adjacent side by side, any one cutter head part 1 is connected with the power source in a linkage way, and when the power source drives the cutter head parts 1 to reciprocate, the rest cutter head parts 1 synchronously reciprocate under the driving of the linkage part 2. One of the plurality of cutter head parts 1 is directly connected with a power source in a linkage way, then the cutter head parts 1 adjacent side by side are connected in a linkage way by using the linkage piece 2, when the power source drives one of the cutter head parts 1 to swing in a reciprocating way, the rest cutter head parts 1 can be synchronously driven to swing in a reciprocating way under the action of the linkage piece 2, so that the swinging piece is relatively reduced, and the production cost is reduced; and the transmission structure of the pruning tool can be greatly optimized, so that the pruning tool can be adapted to multi-tool head assemblies with different purposes or types, and one machine is multipurpose. And secondly, the swinging part is reduced on the body of the pruning tool, and the tightness and the use reliability of the body can be improved to the greatest extent.
To enhance the hair-cutting benefits of the cutting tool, the cutter head part 1 comprises a main cutter head part 11 and one or more auxiliary cutter head parts 12 which are in linkage connection with a power source, the main cutter head part 11 and the auxiliary cutter head parts 12 can have the same hair-cutting purpose or can have different hair-cutting purposes, for example, the main cutter head part 11 can be suitable for cutting long hair, and the auxiliary cutter head parts 12 are mainly suitable for cutting short hair. Of course, the main cutter member 11 and the auxiliary cutter member 12 may be selected from the cutter members 1 for the same hair trimming purpose, and the specific selection may be customized according to the user's needs. Therefore, the main cutter head part 11 does not refer to the cutter head part 1 having a special purpose, and any cutter head part 1 can be regarded as the main cutter head part 11 when being in linkage connection with a power source, and the auxiliary cutter head part 12 which is in synchronous linkage with the main cutter head part 11 under the drive of the linkage member 2 is specifically described herein.
In the actual assembly process, the number of the auxiliary tool bit parts 12 can be selected according to the requirement, and at least one auxiliary tool bit part is arranged. When a plurality of sub-head members 12 are provided, for example, two, three or four sub-head members 12 are provided, the sub-head members 12 may be provided side by side on one side of the main head member 11, or the sub-head members 12 may be provided on both sides of the main head member 11, respectively.
To ensure the hair-cutting performance, the main cutter head part 11 includes a main stationary cutter unit 111 and an active cutter unit 112, and the active cutter unit 112 is disposed in the main stationary cutter unit 111 and is attached to the main stationary cutter unit 111 under the support of the support 13. The driving knife unit 112 is connected with the power source in a linkage way, and can swing back and forth along the main static knife unit 111 under the driving of the power source. The auxiliary tool bit member 12 includes an auxiliary stationary tool unit 121 and an auxiliary movable tool unit 122, and the auxiliary movable tool unit 122 is disposed in the auxiliary stationary tool unit 121 and is attached to the auxiliary stationary tool unit 121 under the support of the support member 13. A supporting piece 13 is additionally arranged below the active knife unit 112 and the auxiliary movable knife unit 122, and the active knife unit 112 and the auxiliary movable knife unit 122 can be always attached to the corresponding main static knife unit 111 and auxiliary static knife unit 121 under the support of the supporting piece 13, so that the hair trimming performance is improved; meanwhile, when the main static cutter unit 111 and the auxiliary static cutter unit 121 bear external force extrusion, the supporting piece 13 can correspondingly contract downwards to provide buffer space for the main static cutter unit 112 and the auxiliary dynamic cutter unit 122, so that the damage to the main static cutter unit 111, the main static cutter unit 112, the auxiliary static cutter unit 121 and the auxiliary dynamic cutter unit 122 after being stressed is effectively avoided, and the use safety and the service life of the main static cutter unit 111, the main static cutter unit 112, the auxiliary static cutter unit 121 and the auxiliary dynamic cutter unit 122 are prolonged.
In order to facilitate the synchronous reciprocating movement of the auxiliary cutter head part 12 along with the main cutter head part 11, a linkage member 2 is arranged between the adjacent driving cutter units 112 and the auxiliary movable cutter units 122, and when the driving cutter units 112 are driven by a power source to reciprocate, the adjacent auxiliary movable cutter units 122 reciprocate in the same direction or opposite directions. When the auxiliary cutter head part 12 has a plurality of auxiliary movable cutter units 122, the linkage piece 2 can be arranged between the adjacent auxiliary movable cutter units 122, so that the active cutter units 112 and the auxiliary movable cutter units 122, the auxiliary movable cutter units 122 and the auxiliary movable cutter units 122 are connected in series, and when the active cutter units 112 and the power source are driven to reciprocate, kinetic energy can be sequentially transmitted under the action of the linkage piece 2, so that each auxiliary movable cutter unit 122 synchronously reciprocates in the same direction or the opposite direction with the active cutter units 112.
To reduce the vibration of the multi-cutter head assembly during the reciprocating swing cutting, the link 2 includes a hinge shaft 21 and a hinge seat 23 provided with a hinge hole 22, and the hinge shaft 21 is fixed to the sub-stationary cutter unit 121. Of course, in the actual production process, the hinge shaft 21 may be fixed to the main stationary blade unit 111 as long as the production process and the assembly are facilitated. The hinge seat 23 is provided with a first linkage end 24 and a second linkage end 25 at two sides opposite to the hinge hole 22, and adjacent driving knife units 112 and auxiliary knife units 122 are respectively connected in a linkage manner through the first linkage end 24 and the second linkage end 25, so that when the driving knife units 112 are driven by a power source to reciprocate, the adjacent auxiliary knife units 122 reciprocate in opposite directions. Through adding respectively setting up first link end 24 and second link end 25 in articulated seat 23 opposite both sides to make first link end 24 and second link end 25 respectively with initiative sword unit 112 and vice movable sword unit 122 linkage connection, when the power supply drives initiative sword unit 112 reciprocal swing, restricted by articulated shaft 21, second link end 25 can only follow first link end 24 opposite direction motion, thereby drive vice movable sword unit 122 reciprocal swing in opposite direction synchronization, when initiative sword unit 112 and vice movable sword unit 122 reciprocal swing in opposite direction synchronization, the vibration sensation that produces when can offset the swing each other, not only can guarantee the stationarity of many tool bit subassembly operation, simultaneously, can also promote the use travelling comfort of pruning instrument.
When the number of the auxiliary cutter members 12 exceeds two, no matter the auxiliary cutter members 12 are arranged side by side on one side of the main cutter member 11 or arranged side by side on two sides of the main cutter member 11, two auxiliary cutter members 12 are necessarily arranged side by side and adjacent to each other, at this time, the linkage member 2 is not only arranged between the main cutter unit 112 and the auxiliary cutter unit 122, but also the linkage member 2 is required to be arranged between the adjacent two auxiliary cutter units 122, so that the main cutter unit 112 and the auxiliary cutter unit 122 as well as the auxiliary cutter unit 122 and the auxiliary cutter unit 122 are respectively connected in a linkage manner through the first linkage end 24 and the second linkage end 25, when the power source drives the main cutter unit 112 to reciprocate, the adjacent main cutter unit 112, the auxiliary cutter unit 122 and the auxiliary cutter unit 122 reciprocate in opposite directions, so that the vibration sense of the multi-cutter assembly during operation can be reduced to the greatest extent, and the use comfort of the pruning tool can be improved.
Of course, the mounting structure of the linkage member 2 may be changed, so that the auxiliary cutter head part 12 and the main cutter head part 11 swing reciprocally in the same direction, for example, the hinge hole 22 of the linkage member 2 is removed, the first linkage end 24 and the second linkage end 25 of the linkage member 2 are respectively fixedly connected or limitedly connected with the active cutter unit 112 and the auxiliary cutter unit 122, and the fixed connection means that the first linkage end 24 and the second linkage end 25 are respectively integrated with the corresponding active cutter unit 112 and the auxiliary cutter unit 122; the limiting connection means that the first linkage end 24 and the second linkage end 25 are respectively connected with the corresponding driving knife unit 112 and the corresponding auxiliary moving knife unit 122 by adopting a limiting structure such as a square hole or a square shaft for limiting rotation; thus, when the power source drives the driving knife unit 112 to reciprocate, the auxiliary moving knife unit 122 can reciprocate along the driving knife unit 112 in the same direction. However, the vibration sense of the multi-knife assembly is relatively strong due to the same direction reciprocating swing, which affects the hand holding feel of the pruning tool and reduces the comfort of use, so that the opposite direction reciprocating swing is a preferred embodiment.
In order to facilitate the hinged assembly of the linkage 2, the auxiliary static knife unit 121 includes an auxiliary static knife 123 and an auxiliary static knife holder 124, the auxiliary static knife holder 124 includes two end plates 125 and two side plates 126, and is sequentially connected to form a frame, the auxiliary static knife 123 is covered above the frame and two sides of the auxiliary static knife are fixedly connected with the corresponding two side plates 126, a positioning seat 127 is provided on at least one side plate 126 of the two side plates 126, and the hinge shaft 21 is fixed on the positioning seat 127. To ensure the installation firmness of the hinge shaft 21, the two end plates 125 and the two side plates 126 are respectively made of metal materials and are enclosed into a whole by welding; of course, plastic materials may be used, and the thickness of the side plate 126 is only increased. The positioning seat 127 is formed by bending along the side plate 126. In the actual production process, the bottom of the two side plates 126 is provided with the sealing plates 128, which are used for connecting the two side plates 126 and welding and fixing the two side plates 126, so that the supporting piece 13 (the supporting piece 13 is preferably a spring) can be fixed by using the spring post 129 arranged on the sealing plates 128 while the working strength of the auxiliary static knife holder 124 is improved, the supporting piece 13 is prevented from being separated, and the auxiliary movable knife unit 122 is always kept attached to the auxiliary static knife 123.
To facilitate the synchronous linkage of the active blade unit 112 and the auxiliary moving blade unit 122, the active blade unit 112 includes an active blade 113 and an active blade holder 114, the active blade 113 is fixed on the active blade holder 114, the auxiliary moving blade unit 122 includes an auxiliary moving blade 122A and an auxiliary moving blade holder 122B, and the auxiliary moving blade 122A is fixed on the auxiliary moving blade holder 122B. The driving grooves 14 which can be matched with the output shafts of the power sources are respectively arranged on the driving tool apron 114 and the auxiliary moving tool apron 122B, and the driving grooves 14 on any driving tool apron 114 or the auxiliary moving tool apron 122B can be connected with the power sources in a linkage way according to the actual assembly condition or the position of the power source (namely the motor output shaft) on the machine body, and in the embodiment, the power source is connected with the driving grooves 14 on the driving tool apron 114 in a linkage way. In order to ensure the synchronous linkage between the auxiliary movable blade holder 122B and the driving blade holder 114, a linkage groove 15 is respectively provided on one side or both sides of the driving groove 14 on the driving blade holder 114 and the auxiliary movable blade holder 122B, and the first linkage end 24 and the second linkage end 25 of the linkage member 2 are respectively disposed in the linkage groove 15, so that the auxiliary movable blade holder 122B is synchronously linked with the driving blade holder 114. The linkage groove 15 is only described as a limiting structure, and does not indicate that only a groove structure can be selected, but also can be arranged as a shaft hole matching structure. For example, in the actual production process, the driving tool holder 114 is provided with the linkage groove 15, and the first linkage end 24 of the linkage member 2 is inserted into the linkage groove 15; the auxiliary movable blade holder 122B is provided with an inwardly recessed slot 16, and the second linkage end 25 is provided with a pin 251, and the pin 251 is inserted into the slot 16 to form a synchronous linkage between the auxiliary movable blade holder 122B and the driving blade holder 114.
