The support rod 1 here plays a supporting and fixing role for the top box 7, and a motor 8 is fixedly connected to the left side of the inner wall of the top box 7. The top box 7 here can ensure the stability of the motor 8 during operation. The driving end of the motor 8 is fixedly connected to a main pulley 9, and the motor 8 here can drive the main pulley 9 here to rotate after starting. The rear end of the main pulley 9 is rotatably connected to the left side of the inner wall of the top box 7, and the right inner wall of the top box 7 is rotatably connected to a slave pulley 10. The top box 7 here provides stable support for the slave pulley 10, and the outer sleeves of the main pulley 9 and the slave pulley 10 are provided with belts 11, and the main pulley 9 and the slave pulley 10 here can drive the belt 11 to start transmission.

[0013] A rotating column 12 is fixedly connected to the outer side of the belt 11. The belt 11 here can drive the rotating column 12 here to move in a rectangular track during transmission. The outer side of the rotating column 12 is slidably connected to a sliding frame 13. Because a groove is provided in the middle of the sliding frame 13 here, when the rotating column 12 slides in the rectangular track, it can drive the external sliding frame 13 to slide left and right. The outer side of the sliding frame 13 is slidably connected to the outside of the top box 7. Both sides of the inner wall of the sliding frame 13 are fixedly connected to the limiting blocks 14.

The clamp 24 here is used to constrain the cable of the driving source of this device, and the left side of the clamp 24 is rotatably connected to a short column 25, and the short column 25 here provides a stable support for the clamp 24.

[0015] Working principle: When you need to move to another location after pruning the trees in this area, you can first rotate the rotating block 5 so that the rotating block 5 is horizontal to the sliding column 3, and then pull out all the sliding columns 3, so that the two support rods 1 and the top box 7 can be folded, which makes it easier for the staff to move positions, saves physical strength, and thus increases the speed of pruning trees. After arriving at the area, the sliding column 3 is reinserted, and under the weight of the counterweight block 6, the rotating block 5 is again in a vertical relationship with the sliding column 3, and the plug column 4 is inserted into the inside of the support rod 1, thereby completing the installation of this device.

[0016] When starting to prune branches, the motor 8 inside the top box 7 can be started to drive the main pulley 9, the secondary pulley 10 and the belt 11 to start transmission, thereby driving the rotating column 12 and the sliding frame 13 to move. At this time, the sliding frame 13 will move left and right under the limit of the limit block 14, and at the same time drive the support plate 15, the rotating shaft 16 and the blade 17 to start pruning the tree, and the staff no longer need to move left and right, which improves the flexibility of the device. At the same time, the protective cover 19 supported by the pillar 18 here can effectively prevent accidental damage to the wires when pruning trees, providing effective safety protection.

[0017] In addition, when connecting the driving source of this device, the clamping jaws 24 can also be pulled to move the two clamping jaws 24 to both sides. At this time, the inner column 23 will squeeze the spring 22 to cause it to contract, generating a greater force. At the same time, the ball 20 and the outer column 21 will rotate accordingly. At this time, the two clamping jaws 24 will open an opening at a certain angle, and then the wires of the driving source are placed between the two clamping jaws 24. Release your hands. At this time, the two clamping jaws 24 can be closed again under the action of the spring 22, thereby completing the restraint of the wires.
