For some branches that are not cut off, they are cut off manually.

[0026] The working principle of the present invention: First, the surrounding seat 1 is installed on the Chinese fir tree trunk. The surrounding seat is composed of a fixed sub-seat 3 and a movable sub-seat 4, which are hinged at one end and connected by a connecting bolt at the other end. When installing, the connecting bolt is opened, and after surrounding the tree trunk, it is fixed. The climbing motor and the crawler feeder in the moving component 2 provide power and support for the surrounding seat to move up and down along the tree trunk; then the annular motor 16 is started, and its rotating end drives the driving gear 17 to rotate. The driving gear meshes with the transition gear 18, and the transition gear then meshes with the annular rack 20, thereby driving the annular rack and the support frame 6 arranged thereon to perform a circular movement, so that the withered branch electric saw 9 and the clamping claws 13 can perform a circular movement; then, according to the growth direction of the withered branch, the angle motor 26 is started, and its rotating end drives the circular gear 28 to rotate. The circular gear meshes with the sector gear 29, and further rotates the main support frame 24. Since the fixing plate 11 is arranged on the main support frame 24 and the auxiliary support frame 25, the fixing plate will deflect, so that the clamping claws 13 can better adapt to the growth direction of the withered branch; when the withered branch enters the clamping claws 13, the transverse sliding component 12 starts to work. The motor drives the screw 33 to rotate, and the moving block 34 cooperating with the screw drives the moving seat 32 and the clamping claws 13 to move, and the claw bodies on both sides of the clamping claws approach. At this time, the cutting motor 38 is started to drive the cutting blade 39 to rotate. As the clamping claws move, the cutting blade quickly cuts off the branched side branches on the withered branch; after the side branch pruning is completed, the annular rotating component continues to work, making the withered branch electric saw 9 approach the root of the withered branch, and starting the withered branch electric saw 9 to cut off the connection between the withered branch and the tree trunk. The withered branch and the cut-off side branches fall to the ground, completing the entire pruning process.
