The free end 31 of the elastic pressure plate 3 is located between the contact 21 of switch 2 and the second pressing part 47. A first trigger part 43, a second trigger part 42, and a third trigger part 41 are provided on the second pressing part 47 corresponding to the free end 31 of the elastic pressure plate 3. The specific arrangement of the first trigger part 43, the second trigger part 42, and the third trigger part 41 on the second pressing part 47 can be set according to actual conditions. Optionally, please refer to [link to relevant documentation]. Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, the first trigger part 43, the second trigger part 42, and the third trigger part 41 are arranged sequentially from left to right on the second pressing part 47.
[0054] Button 4 presses against the free end 31 of the elastic pressure plate 3 from three directions via the first trigger part 43, the second trigger part 42, and the third trigger part 41, thereby activating switch 2. The free end 31 of the elastic pressure plate 3 can have one position for contacting the first trigger part 43, the second trigger part 42, and the third trigger part 41; it can also have two positions for contacting the first trigger part 43, the second trigger part 42, and the third trigger part 41 respectively; or it can have three positions for contacting the first trigger part 43, the second trigger part 42, and the third trigger part 41 respectively. Optionally, please refer to... Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, the elastic pressure plate 3 is provided with a first contact portion 34, a second contact portion 33, and a third contact portion 32 in sequence along the direction from the connecting end 37 toward the free end 31. The first contact portion 34 is bent by the elastic pressure plate 3 toward the contact point 21, and the third contact portion 32 is bent by the elastic pressure plate 3 toward the contact point 21.
[0055] Specifically, the free end 31 of the elastic pressure plate 3 is provided with a first contact portion 34, a second contact portion 33, and a third contact portion 32 from right to left.

For example, please refer to... Figure 1 and Figure 2In this embodiment, the connecting end 37 of the elastic pressure plate 3 is located on the right side of the contact 21. The elastic pressure plate 3 extends downward and to the left from the right side of the contact 21 to the lower side of the contact 21 to form a free end 31, so that the first contact portion 34, the second contact portion 33, and the third contact portion 32 are located on the left side of the connecting end 37. The following will be described with the example of the first contact portion 34, the second contact portion 33, and the third contact portion 32 being located on the left side of the end of the elastic pressure plate 3 connected to the switch 2.
[0056] Further, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, when button 4 moves in the first direction, the first trigger part 43 abuts against the first contact part 34 to move the elastic pressure plate 3 toward the contact point 21 to trigger the contact point 21 to turn on the switch 2; when button 4 moves in the second direction, the second trigger part 42 abuts against the second contact part 33 to move the elastic pressure plate 3 toward the contact point 21 to trigger the contact point 21 to turn on the switch 2; when button 4 moves in the third direction, the third trigger part 41 abuts against the third contact part 32 to move the elastic pressure plate 3 toward the contact point 21 to trigger the contact point 21 to turn on the switch 2.
[0057] Specifically, please refer to Figure 1 and Figure 2 When the handle assembly 100 is in the initial state, button 4 is in the initial position, and the free end 31 is separated from the contact 21. When button 4 is not pressed, the handle assembly 100 is in the initial state, button 4 is in the initial position, the free end 31 of the elastic pressure plate 3 is separated from the contact 21, and button 4 is not triggered by the elastic pressure plate 3.
[0058] Please see Figure 7 and Figure 8 When the handle assembly 100 is in the left-pressed state, the button 4 is in the first trigger position, the first trigger part 43 abuts against the left side of the first contact part 34, and the free end 31 deforms upward to press against the contact 21. When the first pressing part 46 of the button 4 is pressed to the left, the handle assembly 100 is in the left-pressed state, the button 4 moves to the left to the first trigger position, the first trigger part 43 of the button 4 abuts against one side of the first contact part 34 of the elastic pressure plate 3, so that the first trigger part 43 provides an upward pressing force on the free end 31 of the elastic pressure plate 3, so that the free end 31 can deform upward to press against the contact 21 of the switch 2 to trigger the switch 2.
[0059] Please see Figure 5 and Figure 6When the handle assembly 100 is in the upward pressing state, the button 4 is in the second trigger position, the second trigger part 42 abuts against the lower side of the second contact part 33, and the free end 31 deforms upward to press against the contact 21. When the second pressing part 47 of the button 4 is pressed upward, the handle assembly 100 is in the upward pressing state, the button 4 moves upward to the second trigger position, the second trigger part 42 of the button 4 abuts against the lower side of the second contact part 33 of the elastic pressure plate 3, so that the second trigger part 42 provides an upward pressing force on the free end 31 of the elastic pressure plate 3, so that the free end 31 can deform upward to press against the contact 21 of the switch 2 to trigger the switch 2.
[0060] Please see Figure 3 and Figure 4 When the handle assembly 100 is in the right-pressed state, the button 4 is in the third trigger position, the third trigger part 41 abuts against one side of the third contact part 32, and the free end 31 deforms upward to press against the contact 21. When the third pressing part 48 of the button 4 is pressed to the right, the handle assembly 100 is in the right-pressed state, the button 4 moves to the right to the third trigger position, the third trigger part 41 of the button 4 abuts against the right side of the third contact part 32 of the elastic pressure plate 3, so that the third trigger part 41 provides an upward pressing force on the free end 31 of the elastic pressure plate 3, so that the free end 31 can deform upward to press against the contact 21 of the switch 2 to trigger the switch 2.
[0061] The elastic pressure plate 3 is provided with a first contact portion 34, a second contact portion 33, and a third contact portion 32. The specific style of the first contact portion 34, the second contact portion 33, and the third contact portion 32 can be set according to the actual situation. For example, the first contact portion 34, the second contact portion 33, and the third contact portion 32 can all be protrusions or contact surfaces.
[0062] Optionally, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, the first contact portion 34, the second contact portion 33, and the third contact portion 32 are respectively the right contact slope 34a, the contact plane 33a, and the left contact slope 32a. The right contact slope 34a is inclined to the left from top to bottom, and the left contact slope 32a is inclined to the right from top to bottom. The contact plane 33a is located below the right contact slope 34a and the left contact slope 32a.
[0063] Specifically, the lower surface of the elastic pressure plate 3 has a right-side contact slope 34a, a contact plane 33a, and a left-side contact slope 32a, which respectively constitute the first contact portion 34, the second contact portion 33, and the third contact portion 32. When the handle assembly 100 is in its initial state, the right-side contact slope 34a is inclined downwards from right to left relative to the horizontal plane, the contact plane 33a is parallel or approximately parallel to the horizontal plane, and the left-side contact slope 32a is inclined downwards from left to right relative to the horizontal plane. This arrangement of the first contact portion 34, the second contact portion 33, and the third contact portion 32 as contact surfaces simplifies the configuration of these components. Furthermore, the first contact portion 34 is configured as a right-side contact slope 34a, which facilitates the application of an upward pressing force to the free end 31 of the elastic pressure plate 3 through the abutting engagement between the first trigger portion 43 and the first contact portion 34; the second contact portion 33 is configured as a contact plane 33a, which facilitates the application of an upward pressing force to the free end 31 of the elastic pressure plate 3 through the abutting engagement between the second trigger portion 42 and the second contact portion 33; and the third contact portion 32 is configured as a left-side contact slope 32a, which facilitates the application of an upward pressing force to the free end 31 of the elastic pressure plate 3 through the abutting engagement between the third trigger portion 41 and the third contact portion 32.
[0064] Further, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, a portion of the free end 31 is recessed upward relative to the portion adjacent to it in the left-right direction, so as to form a recessed groove 35 on the lower surface of the free end 31.
[0065] Specifically, the free end 31 of the elastic pressure plate 3 located on the right side of the contact 21 is bent multiple times from right to left in the order of upward → left → downward → left, so as to form a downward-facing recessed groove 35 on the right side of the contact 21. The size of the recessed groove 35 gradually decreases from bottom to top in the left and right directions, making the recessed groove 35 a trapezoidal groove.
[0066] Button 4 is provided with a first trigger part 43, a second trigger part 42, and a third trigger part 41. The specific style of the first trigger part 43, the second trigger part 42, and the third trigger part 41 can be set according to the actual situation. For example, the first trigger part 43, the second trigger part 42, and the third trigger part 41 can all be protrusions or abutting surfaces.
[0067] Further, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8In this embodiment, the button 4 is provided with a groove 44 with the slot facing upward. The size of the groove 44 gradually decreases from top to bottom in the left and right directions. The left side wall, bottom wall and right side wall of the groove 44 respectively form a left abutting slope 41a, an abutting plane 42a and a right abutting slope 43a.
[0068] Optionally, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, the first trigger part 43 protrudes from the inner surface of the button 4 toward the handle 1, and the third trigger part 41 protrudes from the inner surface of the button 4 toward the handle 1. This forms a groove 44 between the first trigger part 43 and the third trigger part 41, which helps to prevent other structures on the button 4 from interfering with the contact between the three trigger parts and the three contact parts.
[0069] Please see Figure 1 , Figure 3 , Figure 5 and Figure 7 A spring-loaded reset element is usually provided between the handle 1 and the button 4. The spring-loaded reset element can be a spring 5 or a torsion spring, etc. In this way, the button 4 can be moved back to the initial position by spring reset or torsion reset, so that the free end 31 of the elastic pressure plate 3 is separated from the contact 21 of the switch 2, so as to disconnect the switch 2 and play a safety protection function.
[0070] Optionally, please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In this embodiment, a first spring 5a is provided between the first pressing part 46 and the handle 1, a second spring 5b is provided between the second pressing part 47 and the handle 1, and a third spring 5c is provided between the third pressing part 48 and the handle 1.
[0071] Specifically, the first spring 5a and the third spring 5c are arranged in a left-right direction, with the first spring 5a located to the left of the first pressing part 46 and the third spring 5c located to the right of the third pressing part 48. The second spring 5b is arranged in a vertical direction, located above the second pressing part 47. In this way, the action of the first spring 5a, the second spring 5b, and the third spring 5c allows the button 4 to automatically move and reset to its initial position.
[0072] The elastic pressure plate 3 at contact point 21 adopts a multi-segment bending structure, and the contact area between button 4 and elastic pressure plate 3 is correspondingly provided with two inclined surfaces and one flat surface. When button 4 is pressed upward, the flat surface segment in the middle of button 4 lifts the elastic pressure plate 3, thereby triggering switch 2. When button 4 is pressed to the left or right, the two inclined surfaces of button 4 lift the elastic pressure plate 3, thereby triggering switch 2.
[0073] This utility model also provides a garden tool, which can be a hedge trimmer or a pruning machine, etc. The garden tool includes a handle assembly. Since the structure of the handle assembly adopts the technical solution of the above embodiment, it has the beneficial effects brought about by the technical solution of the above embodiment.
[0074] Garden tools can be equipped with one or more handles. When a garden tool has one handle, that handle can be configured as handle assembly 100; when a garden tool has multiple handles, any one of those handles can be configured as handle assembly 100. Optionally, in this embodiment, the garden tool also includes a housing, a main handle located on one side of the housing, and a shearing blade located on the other side of the housing. The handle assembly 100 is an auxiliary handle, and the handle assembly 100 is connected to the side of the housing away from the main handle.
