[0021] Specifically, the auxiliary handle of the pruning shears is an annular structure, the handle upper cover 1 and the handle lower cover 2 are respectively half-type shells, the handle upper cover 1 and the handle lower cover 2 are connected by screws, a groove for accommodating a micro switch 11 is provided in the handle upper cover 1, and three grooves for accommodating elastic components are also provided, a trigger part 41 of the trigger component 4 is arranged in the cavity of the handle upper cover 1 and the handle lower cover 2, the trigger part 41 corresponds to the three elastic components and the micro switch 11, a No. 1 limiting part 43 and a No. 2 limiting part 44 of the trigger component 4 are arranged in the limiting grooves 3 of the handle upper cover 1 and the handle lower cover 2, and ...4 of the trigger component 4 is arranged in the limiting grooves 3 of the handle upper cover 1 and the handle lower cover 2. The limiting part 43 and the second limiting part 44 are slidably matched with the limiting groove 3. The pressing part 42 of the pressing trigger part 4 can trigger the trigger part 41 to press against the elastic part to turn on the micro switch 11. The trigger part 4 is provided with a first operating part 45, a second operating part 46 and a third operating part 47.

[0022] When working:
[0023] When a person presses the first operating part 45, the first operating part 45 applies force to the first elastic component 12 and the micro switch 11, triggering the micro switch 11 to open the handle;
[0024] When a person presses the second operating part 46, the second operating part 46 presses the second elastic component 13, and at the same time, the first limiting part 43 moves into the limiting groove 3, and the third operating part 47 moves toward the direction of the micro switch 11 with the first limiting part 43 as a fulcrum, thereby driving the first operating part 45 to press against the first elastic component 12 and the micro switch 11, triggering the micro switch 11, and opening the handle;
[0025] When a person presses the third operating part 47, the third operating part 47 presses the third elastic component 14, and at the same time the No. 2 limiting part 44 moves into the limiting groove 3, and with the No. 2 limiting part 44 as a fulcrum, the second operating part 46 moves toward the direction of the micro switch 11, thereby driving the first operating part 45 to press against the first elastic component 12 and the micro switch 11, triggering the micro switch 11, and opening the handle.
[0026] In the above structure, the first elastic component 12, the second elastic component 13 and the third elastic component 14 are distributed in positions, and then cooperated with the trigger component 4, so that the micro switch 11 can be turned on by pressing the trigger component 4 in any direction. The internal structure of the handle is simple, and it is easy to press the trigger component 4 in multiple directions to turn on the handle.
[0027] like Figure 1As shown, in one embodiment, the first elastic component 12, the second elastic component 13 and the third elastic component 14 of the auxiliary handle of the pruning shears are springs, one end of the spring abuts against the handle cover 1, and the other end of the spring abuts against the trigger part 41 of the trigger component 4.
[0028] Specifically, when the trigger component 4 is manually pressed, the trigger portion 41 of the trigger component 4 applies force to the spring, so as to apply force to the button of the micro switch 11, triggering the micro switch 11 to turn on the handle. When the trigger component 4 is manually released, the trigger component 4 returns to the free position under the action of the spring force, and the handle switch is turned off. This arrangement facilitates the pressing and releasing operations of the trigger component 4.
[0029] like Figure 3 As shown, in one embodiment, the trigger portion 41 of the trigger component 4 of the auxiliary handle of the pruning shears is provided with a slot 411 for abutting against the switch of the micro switch 11 and three abutting columns 412 for abutting against the elastic component.
[0030] Specifically, the push button of the micro switch 11 abuts against the slot 411 of the trigger part 41, and the abutting column 412 of the trigger part 41 abuts against one end of the spring. This arrangement facilitates the trigger component 4 to press the micro switch 11 and the spring.
[0031] like Figure 1 As shown, in one of the embodiments, a gap is provided between the first limiting portion 43 and the second limiting portion 44 of the trigger component 4 of the auxiliary handle of the pruning shears and the limiting groove 3 .
[0032] Specifically, when the second operating part 46 and the third operating part 47 are manually pressed, the first limiting part 43 and the second limiting part 44 move into the limiting groove 3, so that the first limiting part 43 and the second limiting part 44 serve as fulcrums. This arrangement facilitates applying pressure to the first operating part 45 to trigger the micro switch 11.
[0033] like Figure 1 As shown, in one embodiment, a groove for accommodating a micro switch 11 and three elastic components is provided in the handle upper cover 1 of the auxiliary handle of the pruning shears. This arrangement facilitates fixing the micro switch 11 and the three elastic components in the cavity when the handle lower cover 2 is connected to the handle upper cover 1.
[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the handle upper cover 1 and the handle lower cover 2 of the auxiliary handle of the pruning shears are connected by screws. This arrangement can reliably connect the handle upper cover 1 and the handle lower cover 2 together.
[0035] like Figure 1 and Figure 2As shown, in one embodiment, the auxiliary handle of the pruning shears also includes a fixing component 5, and the fixing component 5 is used to fix the pruning shears head and other components. This arrangement facilitates fixing other components on the handle.
[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
