The lower end of the hydraulic cylinder 19 extends through to the lower end of the cylinder 1. A handle 20 is connected to the lower end of the hydraulic cylinder 19. A stabilizing ring 21 is connected to one side of the mounting plate 2 corresponding to the rotating shaft 3. One side of the stabilizing ring 21 contacts one side of the first blade 4. Stabilizing rods are circumferentially connected to the middle of the upper end of the handle 20. The upper ends of multiple stabilizing rods extend through to the interior of the cylinder 1.

[0026] The first blade 4 and the second blade 5 can be disassembled and installed by the installation component. A threaded groove is opened on one side of the outer wall of the rotating shaft 3, and a nut is threadedly connected to the outer wall of the rotating shaft 3. The moving component can drive the second blade 5 to move on one side, so that the second blade 5 rotates on the outer wall of the rotating shaft 3, which can achieve automatic pruning of branches. When the operator grips the handle 20, the hydraulic cylinder 19 extends and retracts, driving the cylinder 1 away from the handle 20, and then the first blade 4 and the second blade 5 move away from the handle 20. The first blade 4 and the second blade 5 move upward, which is convenient for pruning branches of different heights.

[0027] The mounting assembly includes a clamping plate 6, one side of which is connected to one end of a rotating shaft 3. A support ring 7 is connected to one side of the clamping plate 6 corresponding to the outer side of the rotating shaft 3. One side of the support ring 7 contacts one side of the second blade 5. A rod 8 is connected to the lower part of one side of the clamping plate 6. One end of the rod 8 extends through to one side of the mounting plate 2. A baffle 9 is connected to the upper and lower ends of the rod 8 corresponding to one side of the mounting plate 2, and one side of each baffle 9 contacts one side of the mounting plate 2. Grooves 10 are evenly spaced on both sides of the rod 8. A buffer spring 11 is connected to one side of the inner wall of each of the two grooves 10. Several buffer springs 11 are connected to the rod 8. One end of spring 11 is connected to one end of several other buffer springs 11 and a stop block 12 is connected to one end of each of the two stop blocks 12. The two stop blocks 12 slide inside the two grooves 10 respectively. One side of each of the two stop blocks 12 contacts one side of the mounting plate 2. Rotating grooves are evenly opened on one side of the support ring 7. Rotating balls are rotatably connected inside the multiple rotating grooves. One side of each of the multiple rotating balls contacts one side of the second blade 5. A moving rod is connected to the lower part of one side of the second blade 5. A sliding groove is opened on one side of the card plate 6 corresponding to the two moving rods. One end of each of the two moving rods is slidably connected inside the sliding groove.

[0028] When it is necessary to disassemble the first blade 4 and the second blade 5, remove the nut from one end of the rotating shaft 3 and remove the mounting bolt 18. Press the two stops 12, so that multiple buffer springs 11 buffer the two stops 12 respectively, and squeeze the two stops 12 into the two grooves 10 respectively. Thus, the two stops 12 release the restriction on the insertion rod 8, so that the insertion rod 8 can move smoothly to one side of the mounting plate 2. Pull the clamping plate 6 to one side, and then drive the insertion rod 8 and the rotating shaft 3 to one side of the mounting plate 2. The two stops 9 move away from the mounting plate 2, so that the rotating shaft 3 moves out of the first blade 4 and the second blade 5, which can release the restriction of the rotating shaft 3 on the first blade 4 and the second blade 5, making it easy to directly remove the first blade 4 and the second blade 5. The first blade 4 and the second blade 5 can be quickly disassembled and assembled. The mounting plate 2 has an opening corresponding to the insertion rod 8, and the insertion rod 8 is located inside the opening.

[0029] The moving component includes a housing 13. A slide cylinder 14 is connected to one side of the upper end of the inner wall of the housing 13. An electric telescopic rod 15 is connected to the lower end of the inner wall of the housing 13 corresponding to the lower end of the slide cylinder 14. A slide rod 16 is connected to the upper end of the electric telescopic rod 15. The upper end of the slide rod 16 extends through to the upper end of the housing 13. Support blocks 17 are connected to both sides of the upper end of the slide rod 16. The two support blocks 17 are in contact with the two sides of the second blade 5 respectively. The upper part of one side of one support block 17 is connected to the second blade 5 and the other support block 17 by a mounting bolt 18.

[0030] The second blade 5 is mounted between two support blocks 17 by mounting bolt 18. When it is necessary to prune the branches, the electric telescopic rod 15 pulls the slide rod 16 downward. The slide rod 16 pulls the support block 17 and the second blade 5 downward, thereby causing the second blade 5 to rotate on the outer wall of the rotating shaft 3. The second blade 5 and the first blade 4 close together, which can prune the branches. While the second blade 5 is rotating, one side of the second blade 5 slides on the side of the support ring 7. Multiple balls on the side of the support ring 7 rotate when the second blade 5 moves. The slide rod 16 moves inside the slide cylinder 14. A mobile battery is connected to the lower end of the inner wall of the housing 13. The mobile battery is electrically connected to the electric telescopic rod 15.

[0031] Working principle: When using the device, the length of the device can be adjusted by extending and retracting the hydraulic cylinder 19, facilitating the pruning of branches at different locations. The operator grips the handle 20 and moves the first blade 4 and the second blade 5 to the pruning point. The electric telescopic rod 15 pulls down the slide rod 16, which in turn moves one side of the second blade 5 downward. The second blade 5 rotates on the outer wall of the rotating shaft 3, and the second blade 5 closes with the first blade 4, completing the pruning operation. After prolonged use, the first blade 4 and the second blade 5 need to be cleaned or replaced. Remove the nut and press the two stops 12. Multiple buffer springs 11 buffer the two stops 12 respectively, allowing the two stops 12 to be moved into position. Inside the groove 10, the clamping plate 6 is pulled to one side, causing the insertion rod 8 to move to one side. When the two stops 12 move into the groove 10, the limit between the insertion rod 8 and the mounting plate 2 is released, and the insertion rod 8 can be moved to one side of the mounting plate 2, causing the rotating shaft 3 to move to one side. The rotating shaft 3 moves away from the first blade 4 and the second blade 5, and the mounting bolt 18 is removed, so that the first blade 4 and the second blade 5 can be disassembled. During the installation process, the first blade 4 and the second blade 5 can be sleeved on the outside of the rotating shaft 3 first, and then the insertion rod 8 is inserted to one side of the mounting plate 2. The two stops 9 limit the position of the insertion rod 8, so that the first blade 4 and the second blade 5 can be installed quickly.
