Referring to fig. 3 to 5, the garden pruning tool according to an embodiment of the present invention includes a first actuator 200, a second actuator 300 and a holder 100, wherein the first actuator 200 and the second actuator 300 are both detachably connected to the holder 100, and the first actuator 200 is also detachably connected to the second actuator 300. When the first actuator 200 is coupled to the holder 100, the garden cutting tool operates in the structure shown in fig. 1, and when the first actuator 200 is coupled to the second actuator 300 and the second actuator 300 is coupled to the holder 100, the garden cutting tool operates in the structure shown in fig. 2. Referring to fig. 3 and 6, the holder 100 includes a trigger assembly and a switching device, the trigger assembly being connected to at least a portion of the switching device. The trigger assembly includes a first trigger 110 and a second trigger 120. The switch device comprises a switch 170 and a mechanical linkage assembly, and the mechanical linkage assembly is arranged at a gap from the switch 170. The switch 170 includes a triggered portion 171, and the mechanical linkage assembly includes a triggering portion 161, and the triggering portion 161 is used for triggering the triggered portion 171, so that the motor of the garden pruning tool is turned on to start working. The triggered part 171 and the triggering part 161 need to undergo two relative position changes before the triggering part 161 can trigger the triggered part 171. When the first actuator 200 is connected to the holder 100, the first trigger 110 drives the triggering portion 161 or the triggered portion 171 to perform the first operation, so that the relative position between the triggering portion 161 and the triggered portion 171 is changed for the first time, and the second trigger 120 drives the triggering portion 161 or the triggered portion 171 to perform the second operation, so that the relative position between the triggering portion 161 and the triggered portion 171 is changed again. Alternatively, the relative positions of the triggering portion 161 and the triggered portion 171 are changed for the first time by the second trigger 120 moving the triggering portion 161 or the triggered portion 171 to perform the second operation, and the relative positions of the triggering portion 161 and the triggered portion 171 are changed again by the first trigger 110 moving the triggering portion 161 or the triggered portion 171 to perform the first operation. That is, the order of operation of the first trigger 110 and the second trigger 120 is not limited, and the first trigger 110 may be operated first, or the second trigger 120 may be operated first. When the first trigger 110 and the second trigger 120 are both operated to cause the first action and the second action to occur, the relative positions of the triggering portion 161 and the triggered portion 171 are changed twice, and the triggering portion 161 can trigger the triggered portion 171 to realize startup. If the holder 100 is sequentially connected to the second actuator 300 and the first actuator 200, when the second actuator 300 is mounted on the holder 100, the mounting action will drive the triggering portion 161 or the triggered portion 171 to perform the first action, so that the relative positions of the triggering portion 161 and the triggered portion 171 are initially changed, and then, only by operating the second trigger 120, the triggering portion 161 or the triggered portion 171 is driven by the second trigger 120 to perform the second action, so that the relative positions of the triggering portion 161 and the triggered portion 171 are changed again, and the triggering portion 161 can trigger the triggered portion 171, so as to implement starting. When the garden pruning tool works in the structure shown in fig. 1, that is, when the holder 100 is assembled with the first actuator 200, a hedge trimmer can be formed to trim a hedge with a small height, and two triggers are required to be operated simultaneously to start the garden pruning tool, and when the garden pruning tool works in the structure shown in fig. 2, that is, when the holder 100 is sequentially assembled with the second actuator 300 and the first actuator 200, a hedge trimmer can be formed to trim a hedge with a large height, and at this time, only one trigger needs to be operated to start the garden pruning tool.

In this embodiment, only need carry a device when pruning, to different pruning height assemble corresponding module can, need not to carry two devices alone, consequently more portable. When the hedge trimmer is used as a hedge trimmer, the hedge trimmer can be started up only by operating two triggers, and when the hedge trimmer is used as a high-branch trimmer, the hedge trimmer can be started up only by operating one trigger, and the operations all meet the safety requirements of the conventional hedge trimmer and the high-branch trimmer.

Referring to fig. 10, further, the outer surface of the second actuator 300 is provided with a protrusion 311, when the second actuator 300 is mounted to the holder 100, the protrusion 311 is mounted into the holder 100 and abuts against at least a portion of the switch device, so that the triggering portion 161 or the triggered portion 171 performs the first action, and the relative position of the triggering portion 161 and the triggered portion 171 is initially changed. When the second actuator 300 is mounted on the holder 100, the protrusion 311 is held against at least a portion of the switch device, and when the second trigger 120 is not operated, the relative positions of the triggering portion 161 and the triggered portion 171 are not reset after the initial change, that is, the relative positions of the triggering portion 161 and the triggered portion 171 are maintained after the initial change. At this time, the second trigger 120 is only required to be operated, the second trigger 120 drives the triggering portion 161 or the triggered portion 171 to perform the second action, so that the relative position between the triggering portion 161 and the triggered portion 171 is changed again, and the triggering portion 161 can trigger the triggered portion 171, so as to implement the startup.

Further, when the triggered part 171 and the triggering part 161 undergo two changes in relative positions, the triggered part 171 and the triggering part 161 come close to each other every time the positions change. In some embodiments, the triggering portion 161 triggers the triggered portion 171 when the triggered portion 171 is close to the triggering portion 161 by a certain distance. For example, the triggering portion 161 and the triggered portion 171 form a photoelectric switch; alternatively, the triggering portion 161 and the triggered portion 171 form a hall switch, and other similar proximity switches may be used. In other embodiments, the triggered part 171 and the triggering part 161 need to be close to each other until the triggered part 171 is triggered by pressing or abutting. Specifically, in some embodiments, the mechanical linkage assembly includes a pressing member, and the triggering portion 161 is disposed on the pressing member to press or abut against the triggered portion 171, so as to complete triggering of the triggered portion 171. In some embodiments, the aforementioned first action and the second action both act on the triggering portion 161, and the triggering portion 161 is moved toward the triggered portion 171 by the first action and the second action to trigger the triggered portion 171. In other embodiments, one of the first action and the second action acts on the triggered part 171, and the other acts on the triggering part 161, and one of the two actions is that the triggered part 171 moves towards the triggering part 161, and the other action is that the triggering part 161 moves towards the triggered part 171.

As described below in the case where both the first motion and the second motion act on the trigger unit 161, when the trigger unit 161 is moved toward the triggered unit 171 by the first motion and the second motion, specifically, the pressing member is connected to the first trigger 110, and the pressing member may be the first pressing member 160 shown in fig. 7 to 12. Referring to fig. 7 and 8, the triggering portion 161 is disposed on the first pressing member 160, and the triggered portion 171 and the second trigger 120 are respectively located at two sides of the triggering portion 161. When the first trigger 110 is operated, the first pushing member 160 is driven to move, so that the triggering portion 161 of the first pushing member 160 moves toward the triggered portion 171 to complete the first action. When the second trigger 120 is operated, the first pushing element 160 is also driven to move, so that the triggering portion 161 of the first pushing element 160 moves toward the triggered portion 171 to complete the second action.

Specifically, in some embodiments, the first trigger 110 is connected to the first push member 160 via the pull member 140. The first trigger 110 and the first pressing member 160 are respectively disposed on two sides of the pulling member 140, and when the first trigger 110 is operated, the pulling member 140 is driven to move, and the pulling member 140 drives the first pressing member 160 to move, so as to complete the first action. When the second trigger 120 is rotated, the second trigger 120 will press the first pushing member 160, so that the triggering portion 161 of the first pushing member 160 moves toward the triggered portion 171 to complete the second action.

For example, referring to fig. 7-9 and 12, in some embodiments, the first trigger 110 and the pull member 140 are both coupled to the cable 130, and when the first trigger 110 is operated, the cable 130 is pulled, and the pull member 140 is pulled by the cable 130. Specifically, the pulling cable 130 may be a steel cable, or may also be a pulling rod. Pulling of the cable 130 may be accomplished by pulling a portion of the first trigger 110. Specifically, the first trigger 110 includes a pulling plate 111 and a first trigger housing 112, the pulling plate 111 is disposed inside the first trigger housing 112, and the two are elastically connected, for example, a first elastic member 181 is disposed between the two. The pulling plate 111 is fixedly connected with the cable 130, and the pulling member 140 is fixedly connected with the cable 130. A partial area of the pulling plate 111 is exposed from the inside of the first plate housing 112 so that the pulling plate 111 can be pulled (i.e., the pulling plate 111 is pressed in an oblique upward direction in fig. 7 or 8). When the pulling plate 111 is pulled, the first elastic member 181 is compressed, the pulling plate 111 pulls the cable 130, the cable 130 pulls the pulling member 140, and the pulling member 140 pulls the first pushing member 160, so that the triggering portion 161 of the first pushing member 160 moves toward the triggered portion 171 to complete the first action. If the pulling plate 111 is released, the pulling plate 111 will move reversely and reset under the driving of the resilience of the first elastic member 181. In the embodiment shown in the drawings, when the pulling plate 111 is pulled, the pulling plate 111, the pulling cable 130, the pulling member 140 and the first pushing member 160 all move, but are not limited thereto, and in other embodiments, at least some of the components may also move in a rotating manner.

For another example, referring to fig. 7 and fig. 11, in other embodiments, the first pressing member 160 is connected to the pulling member 140, the first trigger 110 is connected to the swinging member, and the first trigger 110 can rotate relative to a part of the structure in the holder 100. The pressing member may be a first swinging member 511 shown in fig. 11, when the first trigger 110 is rotated, the first trigger 110 will drive the first swinging member 511 to rotate, when the first swinging member 511 rotates, the first swinging member 511 will abut against the pulling member 140 to move, and the pulling member 140 pulls the first pressing member 160, so that the triggering portion 161 arranged on the first pressing member 160 moves towards the triggered portion 171 to complete the first action. Similarly, referring to fig. 14, the pressing element can be the second swinging element 541 shown in fig. 14, in the embodiment shown in fig. 14, when the pulling plate 111 of the first trigger 110 is pulled, the pulling plate 111 will pull the second swinging element 541 to rotate through the pulling cable 130, and when the second swinging element 541 rotates, the pulling element 140 will be pushed to move. The pressing member may be a second pressing member 542 shown in fig. 14, and when the pulling member 140 moves, the second pressing member 542 is pulled, so that the triggering portion provided on the second pressing member 542 moves towards the triggered portion 171 to complete the first action.

When the holder 100 is connected to the second actuator 300 and the first actuator 200 in turn, the mounting action of the second actuator 300 will replace the action of the first trigger 110. Specifically, referring to fig. 10, in some embodiments, when the protrusion 311 of the second actuator 300 is installed into the holder 100, the pull member 140 is pulled, and the pull member 140 pulls the first push member 160, so that the triggering portion 161 of the first push member 160 moves toward the triggered portion 171 to complete the first action. Furthermore, the pulling member 140 is connected to an abutting member, the protrusion 311 is disposed on the outer surface of the second actuator 300, when the second actuator 300 is installed, the protrusion 311 pushes the abutting member to drive the pulling member 140 to move, and when the pulling member 140 moves, the first pressing member 160 is driven to move, so that the triggering portion 161 moves toward the triggered portion 171. The protrusion 311 abuts against the abutment member to keep the pull member 140 and the first push member 160 at the moved positions.

Specifically, in some embodiments, the abutting member includes a swinging member, the swinging member may be the third swinging member 150 in fig. 10, the third swinging member 150 is connected to the pulling member 140, when the second actuator 300 is connected to the holder 100, the protrusion 311 of the second actuator 300 abuts against the third swinging member 150 to rotate the third swinging member 150, when the third swinging member 150 rotates, the pulling member 140 is pushed to move, the pulling member 140 pulls the first pressing member 160, so that the triggering portion 161 of the first pressing member 160 moves toward the triggered portion 171, and the protrusion 311 abuts against the pulling member 140, so that the pulling member 140 and the first pressing member 160 are both maintained at the moved positions.

In other embodiments, the retaining member may further comprise a pull cord and a slider coupled to the pulling member 140. For example, referring to fig. 12, a pull rope 523 is further connected to the pulling member 140, one end of the pull rope 523 is fixedly connected to the pulling member 140, the other end of the pull rope 523 passes around the pulley 522 and is fixedly connected to the slider 521, and the slider 521 slides in a sliding groove (not shown) in the housing of the holder 100. When the second actuator 300 is installed, the protrusion 311 abuts against the slider 521, the slider 521 pulls the pull rope 523 to pull the pull member 140 to move rightward, the pull member 140 pulls the first pressing member 160 to move the triggering portion 161 of the first pressing member 160 toward the triggered portion 171 to complete the first action, and the protrusion 311 abuts against the slider 521, so that the slider 521 cannot be reset, and the pull member 140 and the first pressing member 160 are both kept at the moved positions.

With reference to fig. 7 to 9, the detailed structure of one embodiment shown in fig. 7 will be additionally described. Specifically, a clamping groove 141 is formed at one end of the pulling member 140 close to the cable 130, an arc-shaped structure 142 is formed inside the clamping groove 141, and when the first trigger is connected with the pulling member 140 through the cable 130, the end of the cable 130 penetrates through a through hole in the arc-shaped structure 142. When the abutting member is the third swinging member 150, the third swinging member 150 is connected to the pulling member 140, specifically, one end of the third swinging member 150 extends into the slot 141, the third swinging member 150 abuts against the arc structure 142, and the third swinging member 150 is provided with the second elastic member 182. Specifically, the second elastic member 182 may be a torsion spring. One end of the torsion spring abuts against the third swinging member 150, and the other end abuts against the housing of the holder 100. Preferably, the third swinging member 150 is provided with an arc surface 151, and the shape and size of the arc surface 151 are matched with the surface of the arc-shaped structure 142, so that the arc surface 151 is more closely attached to the arc-shaped structure 142, and the movement stability is improved. One end of the first pressing member 160 is a trigger portion 161, the other end is rotatably connected with the pulling member 140, and a third elastic member 183 is further disposed between the first pressing member 160 and the pulling member 140. Specifically, the third elastic member 183 may be a torsion spring. The torsion spring can keep the first pressing member 160 away from the switch 170 when no external force is applied, so as to prevent the first pressing member 160 from falling on the triggered portion 171 of the switch 170 due to its own weight.

The second trigger 120 includes a handle 121 and a pressure head 122, which are integrally connected, the second trigger 120 can rotate relative to the housing of the holder 100, the handle 121 and the pressure head 122 are respectively located at two sides of the rotation axis of the second trigger 120, and a fourth elastic member 184 is disposed between the handle 121 and the housing of the holder 100. The ram 122 and the triggered part 171 are located on both sides of the triggering part 161. Preferably, referring to fig. 9, an accommodating groove 1221 is provided on a side of the pressing head 122 close to the triggering portion 161, and has a size slightly larger than that of the triggering portion 161 for accommodating the triggering portion 161, so that when the triggering portion 161 is pressed, the relative position between the two is relatively stable and the deviation and dislocation are not easy to occur.

When the first actuator 200 is connected to the holder 100 to form the hedge trimmer, the pulling plate 111 is pulled, the first elastic member 181 is compressed, the pulling plate 111 pulls the pulling cable 130, and the pulling member 140 is pulled by the pulling cable 130 to move. When the pulling member 140 moves, the side wall of the engaging groove 141 will abut against the upper end of the third swinging member 150, so as to drive the third swinging member 150 to rotate clockwise, and the second elastic member 182 is compressed. When the pulling member 140 moves, the first pushing member 160 is pulled, so that the triggering portion 161 of the first pushing member 160 moves to the right. When the pulling plate 111 is pulled to the limit position (i.e. the first elastic member 181 is compressed to the limit position), the triggering portion 161 has reached the position right above the triggered portion 171, but there is still a certain gap therebetween in the vertical direction. At this point the first action is complete. Then, the handle 121 is pressed to rotate the second trigger 120 clockwise, the pressing head 122 rotates downward, and the fourth elastic member 184 is compressed. When the ram 122 rotates to a certain degree, the groove wall of the receiving groove 1221 will abut against the triggering portion 161, so that the triggering portion 161 rotates downward relative to the pulling member 140 until the triggered portion 171 is pressed and the triggered portion 171 is triggered to complete the second action. At this time, the third elastic member 183 is torsionally deformed. If the pulling plate 111 is released first, the pulling plate 111 will move reversely to reset under the driving of the resilience of the first elastic member 181, the pulling plate 111 will not give a pulling force to the pulling member 140 any more, and at this time, the pulling member 140 will only receive the resilience of the second elastic member 182, and the third swinging member 150 will rotate reversely to reset under the driving of the resilience of the second elastic member 182. After the third swinging member 150 rotates reversely and resets, the pulling member 140 is held to move leftward, the pulling member 140 moves leftward to drive the first pressing member 160 to move leftward, the first pressing member 160 moves leftward to make the triggering portion 161 deviate from the triggered portion 171, that is, the triggering portion 161 and the triggered portion 171 are no longer aligned in the vertical direction, the triggered portion 171 is no longer pressed by the triggering portion 161, and at this time, the hedge trimmer is no longer in the start-up state. If the handle 121 is released first, the second trigger 120 will rotate reversely to reset under the driving of the resilience force of the fourth elastic member 184, the pressing head 122 will not abut against the triggering portion 161 any more, the triggering portion 161 rotates reversely to reset under the driving of the resilience force of the third elastic member 183, and is separated from the triggered portion 171, the triggered portion 171 will not be pressed by the triggering portion 161 any more, and the hedge trimmer will not be in the start-up state any more. Therefore, the hedge trimmer can be no longer in the starting state when any trigger is released. Thereafter, it is still necessary to operate both triggers to open the hedge trimmer to meet the safety requirements of the hedge trimmer. The orientations such as "up, down, left, right" and the like are shown in the view of fig. 7, and the orientations appearing below are also shown in the view of the corresponding drawings, and these orientations are only for convenience of description and understanding, and are not intended to limit the absolute positions thereof.

In addition, if the trigger unit 161 does not complete the first operation, the second operation may be completed first. Specifically, when the second trigger 120 is rotated and the pull plate 111 is pulled, when the second trigger 120 is rotated, the triggering portion 161 is first rotated downward to be close to the triggered portion 171 to complete the second action, but there is still a gap between the triggering portion 161 and the triggered portion 171 in the left-right direction, and when the pull plate 111 is pulled again, the triggering portion 161 moves rightward until the triggering portion 161 moves above the triggered portion 171 to press the triggered portion 171 and trigger the triggered portion 171 to complete the first action.

Referring to fig. 4, 7 to 10, the first connecting end 310 of the second actuator 300 is used for connecting with the holder 100, and the second connecting end 320 is used for connecting with the first actuator 200. The first connection end 310 is provided with a raised protrusion 311 on an outer surface thereof. If the holder 100 is connected to the second actuator 300 and the first actuator 200 in sequence to form a high branch shears, when the second actuator 300 is installed, the protrusion 311 will abut against the lower end of the third swinging member 150 when entering the holder 100, and drive the third swinging member 150 to rotate clockwise, so as to replace the first trigger 110, and the trigger 161 moves to the right to complete the first action. At this time, the second trigger 120 is simply pushed to rotate the second trigger 120 clockwise, so that the triggered part 171 is triggered to complete the second operation.

A detailed description of one embodiment is shown in fig. 11. In this embodiment, the first trigger 110 is connected to the pulling member 140 via an oscillating member. The oscillating piece may be the first oscillating piece 511 in fig. 11. The first swinging member 511 has one end pivotally connected to the pulling plate 111 in the first trigger 110 and the other end connected to the pulling member 140. Specifically, a locking groove 141 is disposed at an end of the pulling member 140 close to the cable 130. The bottom end of the first swinging member 511 extends into the catching groove 141, and the top end of the fourth swinging member 512 extends into the catching groove 141. The remaining structure is similar to the embodiment shown in fig. 7, and thus, the description thereof is omitted. In this embodiment, the abutting member may be the fourth swinging member 512 in fig. 11. One end of the fourth swinging member 512 is connected to the pulling member 140, and the other end of the fourth swinging member 512 can be pressed by the protrusion 311 of the second actuator 300. Similar to the embodiment shown in fig. 7, if the first actuator 200 is connected to the holder 100 to form a hedge trimmer, when the pulling plate 111 is rotated, the pulling plate 111 drives the first swinging member 511 to rotate counterclockwise, so as to abut against the pulling member 140 and move rightward to complete the first action. If the holder 100 is sequentially connected to the second actuator 300 and the first actuator 200 to form a high branch shears, when the second actuator 300 is installed, the protrusion 311 will abut against the lower end of the fourth oscillating member 512, and drive the fourth oscillating member 512 to rotate clockwise, so as to abut against the pulling member 140 and move rightward to complete the first action.

For another example, referring to fig. 14, a detailed description will be given of a specific embodiment shown in fig. 14. In this embodiment, the pressing member may be the second pressing member 542 shown in fig. 14. The pulling element 140 is connected to the second swinging element 541, and the top end of the second swinging element 541 passes through the engaging slot 141 of the pulling element 140 and then is fixedly connected to the cable 130. The positions of the second trigger 120, the second pushing member 542 and the triggered portion 171 are opposite to those of the embodiment shown in fig. 7. Preferably, one end of the second trigger 120 close to the second pushing member 542 is provided with a concave groove (not shown), the groove has an inclined surface (not shown) inclined from the bottom of the second trigger 120 toward the second pushing member 542, the right end of the inclined surface is higher than the left end at the angle shown in the figure, and the surface of one end of the second pushing member 542 is attached to the inclined surface and can slide along the inclined surface. The rotation axis 1211 of the second trigger 120 rotating with respect to the housing of the holder 100 is located at the leftmost end of the second trigger 120, i.e., the end away from the switch 170, and when the second trigger 120 is pressed, the second trigger 120 will rotate counterclockwise around the rotation axis 1211. Preferably, when the second trigger 120 rotates counterclockwise around the rotating shaft 1211, the inclined surface follows the second trigger 120 to rotate counterclockwise around the rotating shaft 1211, so that one end of the second pushing member 542 slides along the inclined surface, and the sliding causes the second pushing member 542 to rotate clockwise around the pulling member 140, that is, the second pushing member 542 rotates towards the triggered portion 171 of the switch 170 to complete the second action. A seventh elastic component 543 for driving the pulling component 140 to move leftwards and return is disposed between the pulling component 140 and the housing of the holder 100, and when the pulling component 140 moves rightwards, the seventh elastic component 543 is compressed. If the first actuator 200 and the holder 100 are connected to form the hedge trimmer, the pulling plate 111 pulls the cable 130, the cable 130 pulls the second swinging member 541 to rotate clockwise, the second swinging member 541 will abut against the pulling member 140 to move rightward when rotating, the pulling member 140 pulls the second pressing member 542 to move rightward to complete the first motion, and at this time, the seventh elastic member 543 is compressed. If the holder 100 is sequentially connected to the second actuator 300 and the first actuator 200 to form a high branch shears, when the second actuator 300 is installed, the protrusion 311 will abut against the lower end of the second swinging member 541, so that the second swinging member 541 rotates clockwise, and abuts against the pulling member 140 to move rightward.

In the holder 100, the pulling member 140 moves rightward so that the triggering portion of the second pushing member 542 is aligned with the triggered portion 171 of the switch 170 in the pushing direction. Specifically, the pulling member 140 moves rightward so that the second pushing member 542 slides along the inclined surface of the second trigger 120 toward the triggered portion 171 of the switch 170, thereby aligning the triggering portion of the second pushing member 542 with the triggered portion 171 of the switch 170 in the pressing direction. At this point, the first action is complete. At this time, when the second trigger 120 is pressed until the second trigger 120 rotates counterclockwise to a certain extent, the second pressing member 542 is pushed by the second trigger 120 to rotate toward the triggered part 171, until the triggering part of the second pressing member 542 presses the triggered part 171, and triggers the triggered part 171 to complete the second action. Specifically, the pushing of the second pushing member 542 by the second trigger 120 includes that the second trigger 120 rotates counterclockwise to cause one end of the second pushing member 542 to slide along the inclined surface, so that the second pushing member 542 rotates obliquely upward around the pulling member 140, and the triggering portion of the second pushing member 542 approaches the triggered portion 171 until the triggered portion 171 is pressed. If the second trigger 120 is pressed first to perform the second action, the second trigger 120 pushes the second pressing member 542, including that the second trigger 120 rotates counterclockwise to make one end of the second pressing member 542 slide along the inclined surface relatively, so that the second pressing member 542 rotates around the pulling member 140 in an inclined upward direction, and the triggering portion of the second pressing member 542 is close to the triggered portion 171, but at this time, a certain distance still exists between the triggering portion of the second pressing member 542 and the triggering portion 171, and thus the second action is completed. At this time, the first trigger 110 is pressed to make the pulling plate 111 pull the cable 130 to move, the cable 130 drives the second swinging member 541 to rotate clockwise, the clockwise rotation of the second swinging member 541 makes the second swinging member 541 abut against the pulling member 140 to move right, the pulling member 140 moves right to make the triggering portion of the second pressing member 542 contact with the triggered portion 171 of the switch 170 and abut against the triggered portion 171 to trigger the triggered portion 171, at this time, the first action is completed, and the switch 170 is triggered.

The following description will be given of a case where one of the first and second actions acts on the triggered portion 171 and the other acts on the triggering portion 161, and one of the first and second actions is a case where the triggered portion 171 moves toward the triggering portion 161 and the other acts on a case where the triggering portion 161 moves toward the triggered portion 171. Referring to fig. 7 and 13, as previously described, in some embodiments, the mechanical linkage assembly includes a pressing member having a trigger portion, and the switch 170 is connected to one of the pressing member and the first trigger 110, and the second trigger. One of the switch 170 and the pressing member connected to the first trigger 110 may be moved by the first trigger 110, and one of the switch 170 and the pressing member connected to the second trigger may be moved by the second trigger, so that the triggering portion and the triggered portion 171 are gradually brought closer to each other until the triggered portion 171 is triggered. For example, in some embodiments, the triggered portion 171 is coupled to the first trigger 110 and the triggering portion is coupled to the second trigger. In one embodiment shown in FIG. 13, the switch 170 is fixedly connected to the switch attachment plate 531, the switch attachment plate 531 is fixedly connected to the pull member 140, the pull member 140 is connected to the cable 130, and the cable 130 is connected to the first trigger 110. The ram 122 acts as a push member, the handle 121 acts as a second trigger, and a partial region of the ram 122 acts as a trigger. In the embodiment, the pushing element is connected to the second trigger in a rotating manner, and when the second trigger is pushed, the pushing element rotates clockwise, so that the triggering portion gradually approaches the triggered portion 171. When the first actuator 200 is connected to the holder 100 to form the hedge trimmer, the pulling plate 111 pulls the pulling cable 130, the pulling cable 130 pulls the pulling member 140, the pulling member 140 pulls the switch fixing plate 531 and the switch 170 fixed on the switch fixing plate 531, so that the triggered part 171 moves to the right to complete the first action. When the second trigger is pressed, the pressing member rotates clockwise, and the trigger portion gradually approaches and triggers the triggered portion 171 to complete the second action. If the second trigger is pressed first, the pressing piece rotates clockwise, the triggering part of the pressing piece approaches the switch 170 in the vertical direction, but the triggering part of the pressing piece is further away from the triggered part 171 in the horizontal direction at this time, and the second action is finished; then, the first trigger 110 is pressed again, the pull plate 111 of the first trigger 110 pulls the cable 130, the cable 130 pulls the pull member 140, the pull member 140 pulls the switch fixing plate 531, and the switch 170 fixed on the switch fixing plate 531, so that the triggered part 171 moves to the right to complete the first action, and the triggered part 171 moves to the right so that the triggering part reaches above the triggered part 171 to press the triggered part 171 to trigger the triggered part 171. If the holder 100 is connected to the second actuator 300 and the first actuator 200 in sequence to form a high branch shears, when the second actuator 300 is installed, the protrusion 311 will abut against the third swinging member 150, so as to abut against the pulling member 140 and move it to the right, and the second actuator 300 keeps the connection relationship with the holder 100, so that the protrusion 311 will abut against the third swinging member 150, so as to keep the pulling member 140, the switch fixing plate 531 and the switch 170 at the position after moving to the right, that is, to keep the triggered part 171 of the switch 170 at the position aligned with the pressing head 122 in the vertical direction (i.e., the pressing direction). At this time, the second trigger is simply pressed to press the ram 122 and trigger the triggered portion 171 of the switch 170, thereby turning on the high branch shears.

The pressing piece is provided with a pressing inclined plane and a pressing plane, if the first action is carried out, the pressing plane is aligned with the triggered part along the pressing direction after the first action is finished, and the pressing plane is abutted against the triggered part after the second action is finished so as to finish triggering. When the second action is performed first, the pressing inclined surface abuts against the triggered part after the second action is completed, and when the first action is completed later, the triggered part gradually changes from abutting against the pressing inclined surface to abutting against the pressing plane, and when the triggered part abuts against the pressing plane, the triggering is completed. For example, referring to fig. 9, the trigger portion 161 of the first pushing member 160 is arched, and the bottom end of the trigger portion 161 includes a pushing inclined plane 1612 and a pushing plane 1611, which are disposed adjacent to each other. In some embodiments, when the holder 100 and the first actuator 200 are assembled to form the hedge trimmer, the first trigger 110 is operated first, and then the second trigger 120 is operated, so that the first change of the positions of the triggering portion 161 and the triggered portion 171 completes the first action, and the pressing plane 1611 is aligned with the triggered portion 171 along the pressing direction. In some embodiments, when the second trigger 120 is operated first and then the first trigger 110 is operated, when the positions of the triggering portion 161 and the triggered portion 171 are changed for the first time, the triggered portion 171 abuts against the pressing inclined surface 1612, and when the positions of the triggering portion 161 and the triggered portion 171 are changed again by pressing the first trigger 110, the triggered portion 171 moves along the pressing inclined surface 1612 relative to the first pressing member 160, the pressing force applied to the triggered portion 171 gradually increases until the pressing force is maximum when the triggered portion 171 is abutted against the pressing plane 1611, and at this time, the triggered portion 171 is triggered. Specifically, referring to fig. 9 and 14, in fig. 9, the pressing plane 1611 and the pressing inclined plane 1612 are both located at the bottom end of the first pressing member 160, the pressing plane 1611 is located at a side close to the second trigger 120, the pressing inclined plane 1612 is located at a side close to the first trigger 110, and the pressing plane 1611 and the pressing inclined plane 1612 are adjacent to each other. In fig. 9, when the first trigger 110 is operated first when the holder 100 and the first actuator 200 are assembled to form the hedge trimmer, and the positions of the triggering portion and the triggered portion 171 are changed for the first time to complete the first action, the pressing plane 1611 is aligned with the triggered portion 171 along the pressing direction, i.e., the pressing plane 1611 is located right above the triggered portion 171 in the view shown in the figure. Then, when the second trigger 120 is operated, the second trigger 120 rotates to make the pressing head 122 press down the first pressing member 160, so that the pressing plane 1611 of the first pressing member 160 presses the triggered part 1711, thereby completing the second action and starting the hedge trimmer. When the second trigger 120 is operated first and the first trigger 110 is operated again, the triggered portion 171 abuts against the pressing inclined surface 1612 when the positions of the triggering portion 161 and the triggered portion 171 are changed for the first time, and when the positions of the triggering portion and the triggered portion 171 are changed again by pressing the first trigger 110, the triggered portion 171 moves along the pressing inclined surface 1612 relative to the second pressing member 542, the pressing force applied to the triggered portion 171 gradually increases until the triggered portion 171 moves to abut against the pressing plane 1611, and at this time, the pressing force is maximized, and the triggered portion 171 is triggered. When the holder 100 is sequentially assembled with the second actuator 300 and the first actuator 200 to form a high branch shears, the protrusion 311 of the second actuator 300 abuts against the third swinging member 150 to rotate the third swinging member 150, the third swinging member 150 rotates to drive the pulling member 140 to move towards the first trigger 110, the pulling member 140 drives the first pressing member 160 to move towards the first trigger 110, and the movement of the first pressing member 160 causes the positions of the triggering portion and the triggered portion 171 to change for the first time to complete the first action, at this time, the pressing plane 1611 is aligned with the triggered portion 171 along the pressing direction, and in the view shown in the drawing, the pressing plane 1611 is located right above the triggered portion 171. Also, the protrusion 311 is held in a state of abutting against the third swinging member 150 in the holder 100, so that the trigger portion and the triggered portion 171 are held in the position after the first change. At this time, when the second trigger 120 is pressed, the second trigger 120 rotates to make the ram 122 press down the first pressing member 160, so that the pressing plane 1611 of the first pressing member 160 presses the triggered part 1711, thereby completing the second action and turning on the high branch shears.

In fig. 14, pressing inclined surface 5421 and pressing plane 5422 are both located at the top end of second pressing member 542, pressing plane 5422 is located at the side close to second trigger 120, and pressing inclined surface 5421 is located at the side close to first trigger 110. In fig. 14, when the holder 100 and the first actuator 200 are assembled to form the hedge trimmer, if the first trigger 110 is operated first, the first trigger 110 drives the cable 130 to move, the cable 130 drives the second swinging member 541 to rotate, the second swinging member 541 rotates to abut against the second pulling member 140 and pushes it to move, the second pulling member 140 drives the second pressing member 542 to move, and when the second pressing member 542 moves, the end portion of the second pressing member 120 abutting against the inclined surface slides along the inclined surface toward the switch 170, thereby completing the first action. When the second trigger 120 is operated again, the second trigger 120 is pressed to rotate, the second trigger 120 rotates to enable the inclined surface to rotate along with the second trigger 120, the inclined surface rotates to enable the second pressing piece 542 to generate relative movement to the inclined surface, the inclined surface further approaches the triggered part 171, and the triggered part 171 is pressed, so that the second action is completed. If the second trigger 120 is operated first, the second trigger 120 is pressed to rotate, the second trigger 120 rotates to make the inclined surface rotate along with the second trigger 120, and the inclined surface rotates to make the second pressing piece 542 generate relative movement to the inclined surface to approach the triggered part 171, so as to complete the first action. Then, the first trigger 110 is operated, the first trigger 110 drives the cable 130 to move, the cable 130 drives the second swinging member 541 to rotate, the second swinging member 541 rotates to abut against the second pulling member 140 and pushes the second pulling member to move, the second pulling member 140 moves to drive the second pressing member 542 to move, and when the second pressing member 542 moves, the end portion of the second trigger 120 attached to the inclined surface slides along the inclined surface toward the switch 170 until the triggered portion 171 is pressed, so that the first action is completed. When the holder 100 is sequentially assembled with the second actuator 300 and the first actuator 200 to form the hedge shears, the protrusion 311 of the second actuator 300 abuts against the second swinging member 541 to rotate the second swinging member 541, so as to replace the operation of the first trigger 110, which is the same as the process after the first trigger 110 is operated during the hedge trimmer and is not described herein again. Also, the protrusion 311 is held in a state of abutting against the second swinging member 541 in the holder 100, so that the trigger portion and the triggered portion 171 are held at the position after the first change. At this time, the second trigger 120 is pressed to open the hedge trimmer, and the process of pressing the second trigger 120 is the same as the process of pressing the second trigger 120 in the hedge trimmer, which is not described herein again.

As mentioned above, the first actuator 200 and the second actuator 300 can be detachably connected to the holder 100, and the first actuator 200 can also be detachably connected to the second actuator 300. The connection structure between the first actuator 200 and the holder 100 and the connection structure between the second actuator 300 and the holder 100 are the same, and the connection structure between the second actuator 300 and the holder 100 is taken as an example for description.

Referring to fig. 6 and 15, in some embodiments, the holder 100 includes a locking member 192 and a locking button 191, the locking member 192 is connected to the locking button 191, the second actuator 300 is provided with a second locking position 312, when the locking button 191 is operated, the locking member 192 is driven to move away from the second locking position 312, and the second actuator 300 is unlocked from the holder 100; when the locking member 192 is extended into the second locked position 312, the second actuator 300 is locked with the holder 100.

In some embodiments, the operation of the locking button 191 will move the locking member 192 away from the second locking position 312. The bottom end of the first connection end 310 of the second actuator 300 is provided with a second locking position 312, and specifically, the second locking position 312 may be a groove. The locking key 191 is provided with a first inclined surface 1911, the locking member 192 is provided with a second inclined surface 1921, and the second inclined surface 1921 is attached to the first inclined surface 1911. A fifth elastic member 185 is disposed between the locking button 191 and the housing of the holder 100, and a sixth elastic member 186 is disposed between the locking member 192 and the housing of the holder 100. When mounting, pushing lock key 191, first sloped surface 1911 slides along second sloped surface 1921 and gives a pushing force to lock 192 where second sloped surface 1921 is located, the pushing force splits a downward component at second sloped surface 1921, the component pushes lock 192 to move downward, and the top end of lock 192 retracts downward to avoid second actuator 300. Then, the first connecting end 310 of the second actuator 300 is inserted into the holder 100, at this time, the locking button 191 is released, the locking button 191 reversely moves and resets, the locking member 192 reversely moves and resets, and the top end of the locking member 192 extends into the second locking position 312, so that locking is achieved.
