assembly is arranged in the knife handle. The limiting
assembly comprises a hollow column, a limiting block and a first clamping ball, the outer wall of the hollow column is fixedly connected to the interior of the cutter handle, one side wall of the clamping ball is fixedly connected to the outer wall of the limiting block, and the outer wall of the limiting block is slidably connected to the interior of the hollow column. According to the grafting knife, the
scabbard is inserted into the knife handle, the clamping block extrudes the first clamping ball and the limiting block and extrudes the telescopic rod and the first spring, locking of the
scabbard is achieved, and the problems that due to the fact that a traditional grafting knife
scabbard is not provided with a fixing structure, the scabbard is prone to loosening or falling in the carrying and high-altitude operation process, a
cutting edge is exposed, and potential safety hazards exist are solved. And the use safety of the tool is improved.
