The hinge shaft then drives the connecting block to rotate, thus allowing the angle of the pruning components to be freely adjusted. This facilitates the pruning of branches with different inclinations, reduces operational difficulty, and improves the efficiency of pruning work. Attached Figure Description

[0022] Please see Figure 1-3 This utility model provides a pruning device for forestry engineering, including a telescopic handle 1, an adjustment component 2, and a shearing component 3. The telescopic handle 1 includes a hand handle 11 and a support rod 12 slidably connected inside the hand handle 11. A first drive component 13 for driving the support rod 12 to slide is provided inside the hand handle 11. The first drive component 13 includes a first motor 131 fixedly installed at the lower end of the hand handle 11 and a screw 132 fixedly connected to the output end of the first motor 131. The screw 132 is arranged along the length direction of the hand handle 11, extends into the support rod 12, and is threadedly connected to the support rod 12. A guide groove 14 is provided on the inner wall of the hand handle 11. Guide blocks 15 that slide in cooperation with the guide groove 14 are fixedly connected to both sides of the lower end of the support rod 12. With the setting of the telescopic handle 1, when adjusting the length, the first motor 131 can be directly started to drive the screw 132 to rotate, so that the screw 132 drives the support rod 12 to extend and retract along the hand handle 11, thereby enabling quick and free adjustment of the length of the device.
[0023] Specifically, the adjustment component 2 includes a housing 21 fixedly installed on the upper end of the support rod 12 and a connecting block 22 hinged to one side of the housing 21. A second drive component 23 for driving the connecting block 22 to rotate is provided inside the housing 21. The second drive component 23 includes a second motor 231 fixedly installed on the outer wall of the housing 21, a worm gear 232 fixedly installed at the output end of the second motor 231, and a worm wheel 233 meshing with one side of the worm gear 232. A hinge shaft 234 is fixedly passed through the axis of the worm wheel 233. Both ends of the hinge shaft 234 are fixedly connected to the connecting block 22. By adjusting the component 2, when pruning branches with different inclinations, the second motor 231 can be activated to drive the worm gear 232 to rotate, which in turn drives the worm wheel 233 to rotate. The worm wheel 233 then drives the hinge shaft 234 to rotate, which in turn drives the connecting block 22 to rotate. This allows for free adjustment of the angle of the pruning component 3, facilitating the pruning of branches with different inclinations, reducing operational difficulty, and improving the efficiency of pruning work.
[0024] Specifically, the shearing assembly 3 includes two blades 31 hinged to one end of the connecting block 22. An electric push rod 32 is fixedly installed inside the connecting block 22. A movable plate 33 is fixedly connected to one end of the electric push rod 32. A connecting rod 34 is hinged between the two blades 31 and the movable plate 33. With the setting of the shearing assembly 3, during pruning, the electric push rod 32 can be activated to drive the movable plate 33 to slide, so that the movable plate 33 drives the two blades 31 to rotate crosswise through the connecting rod 34, thereby causing the two blades 31 to cut the branches.
[0025] Furthermore, a silicone anti-slip sleeve 16 is provided at the lower end of the outer surface of the handheld lever 11. The silicone anti-slip sleeve 16 can improve the comfort of the handheld lever 11. A removable battery 17 is provided at the lower end of the handheld lever 11, which supplies power to the first motor 131, the second motor 231 and the electric push rod 32.
[0026] The working principle and usage process of this utility model are as follows: First, during pruning, the electric push rod 32 can be activated to drive the movable plate 33 to slide, so that the movable plate 33 drives the two blades 31 to rotate crosswise through the connecting rod 34, thereby cutting the branches. Through the setting of the telescopic handle 1, when adjusting the length, the first motor 131 can be directly activated to drive the screw 132 to rotate, so that the screw 132 drives the support rod 12 to extend and retract along the hand handle 11, thereby quickly and freely adjusting the length of the device. Through the setting of the adjustment component 2, when pruning branches with different inclinations, the second motor 231 can be activated to drive the worm gear 232 to rotate, so that the worm gear 232 drives the worm wheel 233 to rotate, and the worm wheel 233 drives the hinge shaft 234 to rotate, which in turn drives the connecting block 22 to rotate, thereby freely adjusting the angle of the cutting component 3, which is convenient for pruning branches with different inclinations, reducing the difficulty of operation and improving the efficiency of pruning work.
