[0002] Bud removal and shoot control is an extremely important and crucial technique in citrus cultivation. It requires pruning the new shoots of fruit trees, which necessitates the use of bud removal shears.

[0003] A search revealed that the announcement number CN217790458U, entitled "A Seedling Cotyledon Bud Removal Tool," includes a mounting bracket. Research and analysis revealed that although it has the advantages of simple operation, high bud removal efficiency, and the ability to avoid damage to other non-bud branches, it also has the following disadvantages to some extent.

[0004] For example, when the device is not in use, it is usually in an open state, and the cutting edge is usually directly exposed. When the device is held and moved, the cutting edge will touch people and cause injury. This is not conducive to people's personal safety and is not convenient for people to use. In order to solve the above technical problems, we have designed a new type of bud-removing shear. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model rotates the positioning block to move it out of the positioning groove. After the positioning block and the positioning groove are no longer engaged, the connecting piece drives the first pull rod and the locking block to move up and down under the action of the return spring. The locking block drives the pull handle to rotate. The connecting piece pushes the second pull rod, causing the second pull rod to move up and down. The second pull rod pushes the movable scissor blade to rotate, causing the blades of the movable scissor blade and the fixed scissor blade to separate.

[0015] 2. This utility model allows the new shoot to be cut to be placed between the movable and fixed scissor blades. Then, pressing the movable scissor blade causes the locking block, the first pull rod, the connecting piece, and the second pull rod to move up and down. The second pull rod drives the movable scissor blade to rotate, and the new shoot is cut by the movable and fixed scissor blades. After one cut, the movable scissor blade can automatically return to its original position under the action of the return spring, which facilitates subsequent continuous cutting. After the cut is completed, the movable and fixed scissor blades are closed, and then the positioning block is locked back into the positioning groove to position the handle and the pull handle, preventing the movable and fixed scissor blades from opening automatically.
