The application principle of the invention is as follows:

when the hand-held hydraulic cylinder is used, a long handle or a short handle is selected according to the requirement, after the hand-held hydraulic cylinder is installed, the hand-held hydraulic cylinder is lifted up to be propped against a branch through a guide inclined plane 13, then the branch is moved along the guide inclined plane and enters between a T-shaped head 3 and a connecting seat 5, the part to be cut of the branch is accommodated in an arc-shaped positioning groove 14 along the trend of the branch, at the moment, the branch is semi-wrapped and positioned by the arc-shaped positioning groove 14, the hand-held hydraulic cylinder is pulled to be propped against the bottom of the arc-shaped positioning groove 14, the handle is pressed, so that the hand-held hydraulic cylinder 1 starts to work, the spike part firstly pierces the branch and is continuously inserted into a through hole, and then the cutting edge cuts off the branch; when the cutting machine is used for cutting off, one part of branches falls down, the other part of branches still remains, and the remaining branches support the hanging part on one side, so that the cutting machine can not suddenly lose support, and an operator can move the cutting machine to a new cutting position.

It is to be noted that, for the high branch, when the branch is positioned until cutting is finished, the user does not need to laboriously hold the handle by virtue of the action of the hanging part, and can finish the cutting work by only pressing, thus greatly reducing the labor intensity; in addition, high-altitude branches can be easily guided into a working area through the guide inclined plane, can be accurately positioned through the branch positioning mechanism, can be further positioned through the spike part and simultaneously crush the cutting part, and can complete cutting under the condition of very labor saving through the hydraulic cylinder; from the above, the invention can improve the pruning efficiency of the branches, ensure the safety of operators and reduce the labor intensity during pruning operation.
