In the present invention, when one of the main trigger component 1 and the sub trigger component 4 is triggered, the relative position between the pressing component 3 and the switch key 511 can be changed, and the other of the main trigger component 1 and the sub trigger component 4 is triggered to make the pressing component 3 press the switch key 511. Therefore, in the invention, switches do not need to be matched with each trigger component, and only one switch is configured to realize that any one of the main trigger component 1 and the auxiliary trigger component 4 is triggered firstly, and the switch key 511 is pressed when the other one is triggered, so that the starting convenience, diversity and selectivity of the garden tool machine are increased, the user experience is improved, the wiring complexity is reduced, and the layout space is saved. Furthermore, in the invention, the switch 51 can be turned on only when the main trigger assembly 1 and the auxiliary trigger assembly 4 are both triggered, thereby improving the use safety of the garden tool machine.

In a possible implementation scheme, as shown in fig. 5, the switch 51 is a bipolar switch, and has 6 insertion pieces 512, and a back electromotive force is formed after power failure by a wiring manner to implement braking, thereby solving the problem that electromagnetic braking is required to be applied when power failure and shutdown occur in the prior art, and reducing cost.

Further, as shown in fig. 1 to 4, the adjusting assembly 2 includes a position adjusting member 21 and a linkage adjusting member 22, the pressing assembly 3 includes a pressing member 31 and a pushing member 32, the linkage adjusting member 22, the pressing member 31 and the switch 51 are all accommodated in the housing 5, one end of the position adjusting member 21 is connected to the main trigger assembly 1, the other end of the position adjusting member 21 is connected to the linkage adjusting member 22, the pressing member 31 is respectively matched with the linkage adjusting member 22 and the pushing member 32, the pressing member 31 is driven by the linkage adjusting member 22 to move from the first position to the second position, and the pressing member 31 is driven by the pushing member 32 to move from the first state to the second state.

In a possible implementation, with continued reference to fig. 3, the pressing assembly 3 further includes an auxiliary pushing member 34 and a rotating shaft 33, the auxiliary pushing member 34 is connected to the pushing member 32, and a side of the auxiliary pushing member 34 away from the pushing member 32 is provided with at least one inclined surface 341, and the inclined surface 341 is in contact with the secondary trigger assembly 4. Preferably, the side of the auxiliary pushing member 34 away from the pushing member 32 is provided with three inclined surfaces 341, which illustratively, as shown in fig. 8, specifically include an inclined surface 341a, an inclined surface 341b and an inclined surface 341c, wherein the inclined surfaces 341b and 341c are symmetrical with respect to the inclined surface 341 a.

Further, the pressing member 31 is rotatably connected to the rotating shaft 33, and the pressing member 31 is rotated around the rotating shaft 33 from the first state to the second state under the pushing of the pushing member 32 to change the relative position with the switch key 511.

In a possible implementation scheme, the main trigger assembly 1 may be triggered first, so that the main trigger assembly 1 drives the adjusting assembly 2 to move from the first position to the second position, that is, the position adjusting member 21 and the linkage adjusting member 22 are sequentially driven to move in a direction close to the second position. Further, the linkage adjusting member 22 drives the pressing member 31 engaged therewith to move toward the second position during the movement. During the movement of the pressing member 31 toward the second position, the relative position between the pressing member 31 and the switch key 511 changes, i.e., the pressing member 31 gradually approaches the switch key 511. Then, the auxiliary trigger assembly 4 is triggered again, the pushing member 32 is driven by the auxiliary trigger assembly 4 to move so as to push the pressing member 31 to move from the first state to the second state, so that the switch button 511 is pressed during the process that the pressing member 31 moves from the first state to the second state, thereby realizing the start of the switch linkage device of the garden tool machine.

It will be appreciated that the first position may refer to an initial position of the adjustment assembly 2 when the main trigger assembly 1 is not triggered. The second position may be a target position reached by the adjusting assembly 2 driven by the main triggering assembly 1 after the main triggering assembly 1 is triggered.

In a possible implementation scheme, the first position may be a fixed position point or a range value, and similarly, the second position may also be a fixed position point or a range value, and the specific setting value may be set according to an actual situation, and is not specifically limited herein. Illustratively, when the first position is a fixed position point, the adjusting component 2 is in the position point when the main trigger component 1 is not triggered, and when the first position is a range value, the adjusting component 2 is in the range when the main trigger component 1 is not triggered. It will be understood that the point at which the adjustment assembly 2 is located at a fixed position may be the point at which the center point of the adjustment assembly 2 is located at the fixed position, or some important mark on the adjustment assembly 2 is located at the point. Correspondingly, the fact that the adjusting component 2 is located within the range may mean that the adjusting component 2 is located within the range as a whole, or may mean that a certain marking element on the adjusting component 2 is located within the range, which may be preset according to requirements, and is not limited specifically here.

Further, the pressing member 31 forms an angle with respect to a pressing direction, the pressing direction is a direction in which the switch key 511 is pressed to turn on the switch 51, the first state may be a state when the sub trigger assembly 4 is not triggered, and an angle included between the pressing member 31 and the pressing direction is defined as an initial angle. The second state may be a state in which the pressing member 31 is driven by the sub-trigger assembly 4 to move after the sub-trigger assembly 4 is triggered, and an included angle between the pressing member 31 and the pressing direction is defined as a target angle.

In another possible implementation scheme, the auxiliary triggering component 4 may be triggered first, the pressing member 31 is driven by the auxiliary triggering component 4 to move from the first state to the second state, the relative position between the pressing member 31 and the switch key 511 changes in the process that the pressing member 31 moves from the first state to the second state, that is, at least a part of the pressing member 31 is gradually perpendicular to the pressing direction, and then the main triggering component 1 is triggered, so that the main triggering component 1 drives the adjusting component 2 to move from the first position to the second position, that is, the position adjusting component 21 and the linkage adjusting component 22 are sequentially driven to move towards the direction close to the second position. Further, the linkage adjusting member 22 drives the pressing member 31 engaged therewith to move from the first position to a direction close to the second position during the movement. The switch button 511 is pressed by a portion of the pressing member 31 perpendicular to the pressing direction while the pressing member 31 reaches the second position, thereby enabling the actuation of the garden tool machine switch linkage.

Further, with continued reference to fig. 1 to 4, the device further includes a housing 5, and the switch 51, the pressing member 31 and the linkage adjusting member 22 are all accommodated in the housing 5. With reference to fig. 2 and fig. 3, the pressing member 31 includes a pressing portion 311 and a rotating portion 312, the pressing portion 311 and the rotating portion 312 are integrally formed, a through hole is formed at a joint of the pressing portion 311 and the rotating portion 312, the rotating shaft 33 is disposed in the through hole so that the pressing portion 311 can rotate around the rotating shaft 33, an included angle is formed between the pressing portion 311 and the rotating portion 312, and specifically, when the secondary trigger assembly 4 is not triggered, the pressing portion 311 and the rotating portion 312 are both disposed at an included angle with the pressing direction. The pressing piece 31 is changed from the first state to the second state, which means that the pressing piece 31 is rotated about the rotating shaft 33 from an initial angle formed with the pressing direction to form the target angle with the pressing direction by the pushing of the pushing piece 32.

Further, the sub trigger assembly 4 includes a sub trigger 41, a sub handle housing 42 and a pushing member 43, the sub trigger 41 is enclosed in the sub handle housing 42, and the pushing member 43 is disposed on the sub trigger 41. Preferably, as shown in fig. 9, the secondary trigger 41 includes at least three triggered directions, namely, the first triggering direction, and a second triggering direction and a third triggering direction, wherein the second triggering direction and the third triggering direction are symmetrical with respect to the first triggering direction. The auxiliary trigger 41 can be triggered in multiple directions, and operation convenience is improved. The pushing part 43 includes an accommodating space for accommodating the auxiliary pushing part 34, and at least one pushing inclined surface 431 corresponding to the inclined surface 341 is provided on an inner wall of the accommodating space of the pushing part 43, as shown in fig. 10, for example, specifically including: three abutting slopes 431b,431 a,431 c corresponding to the slopes 341b,341 a,341 c, respectively. Wherein the push slopes 431b and 431c are symmetrical with respect to 431 a.

As shown in fig. 2 and 6, when the secondary trigger assembly 4 is not triggered, the inclined pushing surface 431a of the pushing member 43 contacts the inclined surface 341a of the auxiliary pushing member 34, and the pushing member 32 is separated from the pressing member 31. When the auxiliary trigger 41 is pressed along the first triggering direction, the auxiliary triggering assembly 4 is triggered, the auxiliary trigger 41 moves along the first triggering direction, so that the pushing part 43 of the auxiliary trigger 41 moves along the first triggering direction, and the pushing part 43 generates pushing force on the auxiliary pushing part 34 in the moving process, so as to drive the auxiliary pushing part 34 to move. Specifically, when the pushing inclined surface 431a of the pushing member 43 moves along the first triggering direction, a pushing force is generated on the inclined surface 341a of the auxiliary pushing member 34 along the pushing direction, the pushing force is decomposed into a component force in the first component force direction and a component force in the second component force direction on the inclined surface 341a, the component force in the first component force direction causes the auxiliary pushing member 34 on which the inclined surface 341a is located to move along the first component force direction, but the movement is blocked by the inner wall of the accommodating space, so that the auxiliary pushing member 34 is prevented from moving along the first component force direction; as shown in fig. 7, the component force in the second force dividing direction causes the auxiliary pushing member 34 on which the inclined surface 341a is located to move along the second force dividing direction, so as to drive the pushing member 32 connected to the auxiliary pushing member 34 to move along the second force dividing direction, the pushing member 32 contacts the rotating portion 312 of the pressing member 31 after moving along the second force dividing direction, and the pushing member 32 continues to move along the second force dividing direction to push the pressing member 31 on which the rotating portion 312 is located to rotate around the rotating shaft 33, so that the pressing member 31 rotates from the first state to the second state.

When the auxiliary trigger 41 is pressed along the second triggering direction, the auxiliary trigger drives the abutting piece 43 to move along the second triggering direction, so that the abutting inclined surface 431b of the inner wall of the accommodating space abuts against the inclined surface 341b, and the auxiliary pushing piece 34 where the inclined surface 341b is located moves along the second force dividing direction. Specifically, when the sub trigger 41 is pressed in the second triggering direction, the sub trigger 41 drives the pushing member 43 to move in the second triggering direction, the accommodating space of the pushing member 43 moves in the second triggering direction, the pushing inclined surface 431b of the inner wall of the accommodating space pushes against the inclined surface 341b of the auxiliary pushing member 34, the pushing force decomposes a component force in the second component force direction and a component force in other directions at the inclined surface 341b, the component force in other directions intends to move the auxiliary pushing member 34 in other directions, but the inner wall of the accommodating space prevents the auxiliary pushing member 34 from moving in other directions, so that the auxiliary pushing member 34 can only move in the second component force direction under the driving of the component force in the second component force direction, and thus the pushing member 32 is driven to move in the second component force direction and then contacts the rotating portion 312 of the pressing member 31, and the pushing member 32 continues to move in the second component force direction and push the pressing member 31 at the rotating portion 312 to rotate around the rotating shaft 33, so that the pressing member 31 rotates from the first state to the second state.

When the auxiliary trigger 41 is pressed in the third triggering direction, the auxiliary trigger 41 drives the abutting piece 43 to move in the third triggering direction, the accommodating space of the abutting piece 43 moves in the third triggering direction, the abutting inclined surface 431c of the inner wall of the accommodating space abuts against the inclined surface 341c of the auxiliary pushing piece 34, and since the abutting inclined surfaces 341c and 341b are symmetrical with respect to the inclined surface 341a, the abutting force decomposes the component force in the second force dividing direction and the component force symmetrical with the component force in the other direction at the inclined surface 341c, and similarly, the inner wall of the accommodating space prevents the auxiliary pushing piece 34 from moving in the direction symmetrical with the other direction, so that the auxiliary pushing piece 34 can only move in the second force dividing direction under the component force driving in the second force dividing direction, thereby driving the pushing piece 32 to move in the second force dividing direction and then contact with the rotating portion 312 of the pressing piece 31, and the pushing piece 32 continues to move in the second force dividing direction and push the pressing piece 31 located at the rotating portion 312 to rotate around the rotating shaft 33, so that the pressing piece 31 rotates from the first state to the second state.

In a possible implementation, the position adjusting member 21 may be configured as a pull rope, and when the position adjusting member 21 is configured as a pull rope, one end of the pull rope is connected to the main trigger assembly 1, and the other end of the pull rope is connected to the linkage adjusting member 22. When the main trigger assembly 1 is triggered, the main trigger assembly 1 pulls the pull rope to move, and the pull rope pulls the linkage adjusting piece 22 to move. Illustratively, as shown in fig. 1, the main trigger assembly 1 includes a main trigger 11 and a main handle housing 12, wherein an installation shaft is disposed on the main handle housing 12, the main trigger 11 is provided with an installation hole, and the installation hole of the main trigger 11 is sleeved on the installation shaft to achieve a rotational connection between the main trigger 11 and the main handle housing 12.

Furthermore, the outside package of stay cord is equipped with the insulating layer to play the guard action to the stay cord. Specifically, after the second clamping piece is matched with the second clamping groove, when the main trigger assembly 1 is triggered, the main trigger assembly 1 pulls the pull rope to move, the pull rope drives the second clamping piece to move, and then the second clamping piece drags the linkage adjusting piece 22 to move together from the first position to the second position.

Further, in a possible implementation scheme, as shown in fig. 2, an avoidance space 221 is formed in the linkage adjusting member 22, a part of the pressing member 31 is disposed in the avoidance space 221, and another part of the pressing member 31 is exposed outside the avoidance space 221. Specifically, one end of the rotating portion 312 of the pressing member 31, which is far away from the rotating shaft 33, is exposed out of the avoiding space 221 and is located on one side of the linkage adjusting member 22, which is close to the pushing member 32, and when the pushing member 32 is pushed by the auxiliary pushing member 34 to move in the second force dividing direction, the pushing member 32 contacts with one end of the rotating portion 32 exposed out of the avoiding space 221, so that the pressing member 31 is pushed to rotate from the first state to the second state; one end of the pressing portion 311 of the pressing member 31, which is far away from the rotating shaft 33, is exposed outside the escape space 221 and is located on one side of the linkage adjusting member 22, which is close to the switch 5, and when the pressing member 31 is located at the second position and is in the second state, one end of the pressing portion 311, which is exposed outside the escape space 221, presses the switch key 51. Preferably, the cord is made of a metal wire, and one end of the cord is engaged with the main handle case 12 of the main trigger unit 1 by a first engaging member, and the other end is engaged with the inside of the case 5 by a second engaging member 6.

Further, in a possible implementation scheme, as shown in fig. 3 and 4, an inner wall of the housing 5 protrudes inward to form a spring abutting block 52, the adjusting assembly 2 further includes a first return spring 23, the first return spring 23 is located in the linkage adjusting member 22, one end of the first return spring 23 is connected or abutted to the inner wall of the linkage adjusting member 22, and the other end of the first return spring 23 is connected or abutted to the spring abutting block 52, so that the linkage adjusting member 22 is returned from the second position to the first position. Illustratively, the linkage adjusting member 22 has a receiving groove, one end of the receiving groove is an open port, the other end of the receiving groove is a closed port, the first return spring 23 is located in the receiving groove of the linkage adjusting member 22, the spring abutting block 52 of the housing 5 is located at the open port, one end of the first return spring 23 may abut against a groove wall of the closed port, and the other end of the first return spring passes through the open port to connect or abut against the spring abutting block 52. Further, in another possible implementation, the first return spring 23 may also be disposed inside the switch housing 5 and outside the linkage adjuster 22. For example, the first return spring 23 may be located between the switch housing 5 and the linkage adjuster 22, and one end of the first return spring 23 may be connected to an inner wall of the switch housing 5, and the other end thereof may be connected to an outer wall of the linkage adjuster 22. Under this kind of structure, after main trigger subassembly 1 is triggered, main trigger subassembly 1 drives position control spare 21 by the first position to the direction motion that is close to the second position, and position control spare 21 drives linkage regulating part 22 simultaneously and moves to the direction that is close to the second position, and in the motion process, position control spare 21 drives this first reset spring 23 and is stretched, after loosening main trigger subassembly 1, first reset spring 23 resets, and then drives linkage regulating part 22 and reset to the first position.

It should be noted that the installation position and the connection manner of the first return spring 23 described above are only an exemplary illustration, and in other possible implementations, the first return spring 23 only needs to drive the linkage adjusting member 22 to return to the first position, and the specific installation position or the connection manner thereof is not specifically limited.

Further, with reference to fig. 2 and fig. 3, the pressing assembly 3 further includes a second return spring 35, the second return spring 35 is located in the avoiding space 221 of the linkage adjusting member 22, one end of the second return spring 35 is connected to the pressing member 31, and the other end of the second return spring 35 is used for being connected to or abutted against the inner wall of the linkage adjusting member 22, so that the pressing member 31 is returned from the second state to the first state. For example, one end of the second return spring 35 may be connected to the pressing member 31, and the other end thereof may be connected to an inner wall of the interlocking adjuster 22, and in particular, one end of the second return spring 35 is connected to the inner wall of the interlocking adjuster 22, and the other end thereof is connected to an end of the rotating portion 312 of the pressing member 31. It should be noted that, in this structure, when the secondary trigger assembly 4 is triggered, the secondary trigger assembly 4 drives the pressing member 31 to move from the first state to a direction close to the second state, the pressing member 31 compresses the second return spring 35 in the process of moving to the second state, and after the secondary trigger assembly 4 is released, the second return spring 35 returns to the original position, and then the pressing member 31 is driven to return to the first state. Further, in another embodiment, one end of the second return spring 35 may be connected to the pressing member 31 and the other end thereof may abut against the interlocking adjuster 22, or one end of the second return spring 35 may abut against the pressing member 31 and the other end thereof may be connected to the interlocking adjuster 22.

Specifically, the main trigger assembly 1 sequentially drives the position adjusting member 21 and the linkage adjusting member 22 to move towards the second position. The linkage adjusting piece 22 drives the pressing piece 31 matched with the linkage adjusting piece to move towards the second position in the process of moving. During the movement of the pressing member 31 toward the second position, the pressing member 31 gradually approaches the switch key 511. Then, the auxiliary trigger assembly 4 is triggered again, the auxiliary trigger assembly 4 drives the pushing member 32 to move so as to push the pressing member 31 to move from the first state to the second state, and the switch button 511 is pressed by the pressing member 31 in the process of moving from the first state to the second state, so that the switch linkage device of the garden tool machine is started.

Or, when the auxiliary triggering assembly 4 is triggered first, the auxiliary triggering assembly 4 drives the pressing member 31 to move from the first state to the second state, and the relative position between the pressing member 31 and the switch key 511 changes in the process that the pressing member 31 moves from the first state to the second state. Specifically, at least a portion of the pressing piece 31 is gradually perpendicular to the pressing direction. Then, the main trigger assembly 1 is triggered again, and the main trigger assembly 1 drives the adjusting assembly 2 to move from the first position to the second position. Specifically, the main trigger assembly 1 sequentially drives the position adjusting member 21 and the linkage adjusting member 22 to move towards the second position. The linkage adjusting piece 22 drives the pressing piece 31 matched with the linkage adjusting piece to move from the first position to the second position in the moving process. At the same time when the pressing member 31 reaches the second position, the switch button 511 is pressed by a portion of the pressing member 31 perpendicular to the pressing direction, so that the garden tool machine switch linkage is started, i.e., the pressing member 31 gradually approaches the switch button 511.

It should be noted that the installation position and the connection manner of the second return spring 35 described above are only an exemplary illustration, and in other possible implementations, the second return spring 35 only needs to be able to drive the pressing member 31 to return to the first state, and the specific installation position or the connection manner thereof is not specifically limited.
