[0012] In summary, this application includes the following beneficial technical effects:

[0013] The lifting plate is raised to a suitable height by the lifting assembly so that the branch to be pruned passes between the two clamping plates. By starting the two hydraulic cylinders, the two clamping plates are driven to move closer to each other when the hydraulic cylinders move, thereby clamping and fixing the branch to avoid bending of the branch when the branch is pruned.

The output ends of the two hydraulic cylinders 3 are fixedly connected to the clamping plate 4; the cutting assembly includes a transverse groove 5 opened on the surface of the lifting plate 2, and the inner wall of one end of the transverse groove 5 is fixedly connected to a forward and reverse motor 6. The output end of the forward and reverse motor 6 is fixedly connected to a screw rod 7 through a coupling. The external thread of the screw rod 7 is connected to a sliding seat 8. The surface of the sliding seat 8 is fixedly connected to an electric push cylinder 9. The output end of the electric push cylinder 9 is fixedly connected to a cutting machine 10. The lifting plate 2 is raised to a suitable height through the lifting assembly so that the branches to be pruned pass through the two clamping plates 4 By starting the two hydraulic cylinders 3, the movement of the hydraulic cylinders 3 will drive the two clamping plates 4 to approach each other, thereby clamping and fixing the branches to avoid bending of the branches when pruning them. By starting the forward and reverse motors 6, the forward and reverse motors 6 start to drive the screw rod 7 to rotate, and the rotation of the screw rod 7 drives the sliding seat 8 outside it to move outside the screw rod 7. The bottom of the sliding seat 8 fits tightly with the bottom of the transverse groove 5, thereby avoiding the sliding seat 8 from rotating and deviating when the outside of the screw rod 7 moves, until the sliding seat 8 drives the cutting machine 10 to move to the appropriate position. The operation of the cutting machine 10 will drive the cutting disk to rotate at high speed, and the electric push cylinder 9 will be started. The movement of the electric push cylinder 9 will drive the cutting machine 10 and move toward the branches, thereby realizing the cutting and pruning of the branches.

When the hydraulic cylinders 3 move, the two clamping plates 4 are driven to move closer to each other, thereby achieving the clamping and fixing of the branches. The arc-shaped protrusions 18 can increase the friction between the two clamping plates 4 and the branches, thereby increasing the stability of the clamping plates 4 when clamping the branches, and avoiding the bending of the branches when pruning the branches. By starting the forward and reverse motors 6, the forward and reverse motors 6 start to drive the screw rod 7 to rotate. The rotation of the screw rod 7 drives the sliding seat 8 outside it to move outside the screw rod 7. The bottom of the sliding seat 8 is tightly fitted with the bottom of the transverse groove 5, thereby avoiding the sliding seat 8 from rotating and deviating when the outside of the screw rod 7 moves, until the sliding seat 8 drives the cutting machine 10 to move to a suitable position.
