[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] The present application embodiment discloses a tea tree pruning device, referring to Figure 1-Figure 2 , including a base 1, a frame 4 is arranged above the base 1, a lifting member is arranged between the frame 4 and the base 1, one side of the frame 4 is opened, a movable fixing frame 5 is arranged on the open side of the frame 4, a cutting blade 3 is rotatably inserted inside the fixing frame 5, the edge of the cutting blade 3 protrudes to the outside of the fixing frame 5, a motor 6 is fixedly installed above the fixing frame 5, the output end of the motor 6 passes through the fixing frame 5 and extends to the inside of the fixing frame 5, and the output end of the motor 6 is fixedly connected to the center of the cutting blade 3.

[0018] The lifting member comprises an electric push rod 2 , which is fixedly mounted above the base 1 . The electric push rod 2 is arranged vertically, and an output end of the electric push rod 2 is fixedly connected to a frame 4 .

[0019] When pruning the tea tree, the electric push rod 2 drives the frame 4 to rise and fall above the base 1, so as to adjust the position of the cutting blade 3 according to the height of the tea tree. The motor 6 drives the cutting blade 3 to rotate to prune the tea tree. The fixing frame 5 is moved out from the inside of the frame 4, so that the fixing frame 5 can drive the cutting blade 3 to extend outward, thereby being able to prune tea trees of different depths, making the device more widely applicable.

[0020] Reference Figure 2 Two groups of connecting rods 10 are arranged inside the frame 4, and the centers of the two groups of connecting rods 10 are both connected by hinge shafts 9. Push blocks 8 are rotatably installed at both ends of the connecting rods 10, wherein the two groups of push blocks 8 are slidably connected to the fixed frame 5, and a driving structure is arranged between the other two groups of push blocks 8, and the driving structure drives the two groups of push blocks 8 to move closer to or away from each other.

[0021] The driving structure comprises a threaded rod 7 , which is rotatably inserted into the interior of the frame 4 , the threaded rod 7 is horizontally arranged, and the threaded rod 7 and the push block 8 are threadedly connected.

[0022] When adjusting the position of the fixing frame 5, the threaded rod 7 is rotated. Since the threaded rod 7 is threadedly connected to the push block 8, the threaded rod 7 can drive the two groups of push blocks 8 to move closer to or away from each other. When the two groups of push blocks 8 are close to each other, the two groups of connecting rods 10 are driven to rotate around the hinge shaft 9, thereby pushing the fixing frame 5 away from the frame 4. When the two groups of push blocks 8 are close to each other, the connecting rod 10 pulls the fixing frame 5 to move in the direction close to the frame 4.

[0023] Reference Figure 3 A slide groove 11 is provided inside the push block 8, a slider 12 is slidably inserted inside the slide groove 11, the slider 12 is rotatably connected to the connecting rod 10, a spring 13 is movably inserted inside the slide groove 11, and the spring 13 is connected to the slider 12.

[0024] When pruning tea trees, if you encounter some thick branches that cannot be pruned, you can push the fixing frame 5 vertically toward the frame 4. At this time, the fixing frame 5 pushes the two sets of sliders 12 to slide inside the slide groove 11 through the connecting rod 10. The two sets of sliders 12 move away from each other. At this time, the spring 13 is deformed by the force, thereby being able to provide a certain degree of protection for the cutting blade 3.
