[0023] This utility model discloses a cylindrical pruning tool. By setting the blade holder 1 and the blade 2 in a circular shape, the blade 2 can be driven to rotate around its own axis by a drive mechanism during pruning. At the same time, the blade 2 can be driven to move up and down in the vertical direction by a lifting mechanism, so as to prune the cylindrical side of the plant. The structure is simple and the pruning efficiency is high. At the same time, the circular shape of the blade 2 increases the rigidity of the blade 2 and reduces the wear of the blade 2.

[0024] In one specific embodiment of this application, the end of the tool holder 1 away from the mounting part 4 extends outward with an annular flange 6. The flange 6 extends horizontally and forms a ring shape. A plurality of fixing holes 7 are evenly distributed on the flange 6 around the axis of the tool holder 1. The tool holder 1 can be detachably mounted on the drive mechanism by screws through the fixing holes 7, so as to facilitate the assembly and disassembly of the tool holder 1.

[0025] In another specific embodiment of this application, the inner wall of the tool holder 1 is provided with a mounting groove 20 at the mounting part 4. The blade 2 is fixedly mounted on the mounting groove 20. The mounting groove 20 is used to position the blade 2, which facilitates the installation of the blade 2 and improves the stability of the blade 2 installation. Furthermore, a plurality of mounting holes 8 are evenly distributed around the mounting groove 20. The end of the blade 2 is provided with a connecting hole 9 that corresponds to and mates with the mounting hole 8. Thus, the blade 2 can be detachably and fixedly mounted on the tool holder 1 by using a fixing screw to engage the mounting hole 8 and the connecting hole 9, thereby facilitating the disassembly and replacement of the blade 2.

[0026] In addition, such as Figure 4 As shown, this application also discloses a cylindrical pruning device, including any of the above-described pruning blades, a drive mechanism for driving the pruning blades to rotate, and a lifting mechanism for driving the pruning blades to move up and down in the vertical direction.

[0027] This utility model discloses a cylindrical pruning device. By setting the blade holder 1 and the blade 2 in a circular shape, the blade 2 can be driven to rotate around its own axis by a drive mechanism during pruning. At the same time, the blade 2 can be driven to move up and down in the vertical direction by a lifting mechanism, so as to prune the cylindrical side of the plant. The structure is simple and the pruning efficiency is high. At the same time, the circular shape of the blade 2 increases the rigidity of the blade 2 and reduces the wear of the blade 2.

[0028] In one specific embodiment of this application, the lifting mechanism includes a mounting frame 10, a lifting seat 11 movably mounted on the mounting frame 10, and a first drive assembly for driving the lifting seat 11 to move vertically relative to the mounting frame 10. Specifically, the first drive assembly includes a first drive motor 12 and a lead screw 13.

The opposite sides of the lifting seat 11 are slidably engaged with the slide rail 14 via rollers 15. The middle part of the lifting seat 11 is threadedly engaged with the lead screw 13. The first drive motor 12 controls the rotation of the lead screw 13, thereby driving the lifting seat 11 to move up and down relative to the mounting frame 10.

[0029] In this application, the driving mechanism includes a rotating base 16 and a second driving assembly for driving the rotating base 16 to rotate. The rotating base 16 is cylindrical, and its upper end is rotatably connected to the lifting base 11. The pruning blade is fixedly installed at the lower end of the rotating base 16. Specifically, the second driving assembly includes a second driving motor 17 and a transmission belt 18.
