Examples

As shown in fig. 1 to 4, the portable bark shearer for grafting in the embodiment includes two scissor arms 100 hinged to each other, a scissor head 120 is disposed at a front end of the scissor arm 100, a scissor handle 110 is disposed at a rear end of the scissor arm 100, fixing sleeves 200 are disposed on the scissor heads 120, the fixing sleeves 200 are U-shaped in cross section and have open ends arranged opposite to each other, the rear end of the fixing sleeves 200 is hinged to the rear end of the scissor head 120, the fixing sleeves 200 at least wrap a blade of the scissor head 120, clamping springs 210 are disposed on the fixing sleeves 200, and the clamping springs 210 always apply a mutually closed elastic force to the fixing sleeves 200.

By the scheme of the embodiment, the fixing sleeve 200 can clamp the branches under the clamping action of the clamping spring 210, and the cutting action of the scissor head 120 cannot be influenced to cut the branches in the clamping process; the securing sleeve 200 also serves to protect the scissor head 120 and prevent the fingers or other parts of the tree from being cut during use.

An opening spring 130 is arranged between the scissor arms 100 in the embodiment, and the opening spring 130 always pushes the scissor handles 110 to open the scissor heads 120.

In this embodiment or other embodiments, the front end of the fixing sleeve 200 is provided with a guide inclined surface 230, and the guide inclined surfaces 230 of the two fixing sleeves 200 are formed in a flared shape. When the device is used, the device is pushed towards the branches to be cut, so that the branches prop open the fixing sleeve 200 along the guide inclined plane 230 to reach the cutting edge, and the cutting is convenient; the fixing sleeve 200 does not need to be manually broken, and the use convenience is improved.

In this or other embodiments, the two ends of the clamping spring 210 are fixed to the front end of the fixing sleeve 200 and the front end of the scissor head 120, respectively. The interference can not be caused to the opening and closing of the fixed sleeve 200 and the scissor head 120, the fixed sleeve 200 can be tensioned in the closed shearing process of the scissor head 120, so that the fixed sleeve 200 clamps the branches, and the positioning effect is improved.

In this embodiment or other embodiments, the bottom of the outer side of the fixing sleeve 200 is a fixing edge 201. In the clamping process, the fixed blade 201 can cut into the top of the branch, so that the fixing effect is improved, and the sliding deviation of the branch in the shearing force applying process is avoided.

In this embodiment or other embodiments, the middle of the fixing sleeve 200 corresponding to the cutting edge of the scissor head 120 is provided with a positioning slot 220, and the depth of the positioning slot 220 is smaller than the distance that the scissor head 120 moves when the scissor head 120 is opened, so that the scissor head 120 is always hidden in the fixing sleeve 200 in a naturally opened state without exposing the positioning slot 220. The positioning groove 220 can further play a role in positioning, and the slipping of the branches caused in the process of clamping the branches by the fixed sleeve in the use process is avoided.
