The right end of the inner handle extends out of the right end of the inner handle sleeve and is combined with the disc-like cutter head into a whole. An acute-angled cutter integrated with the cutter head is arranged at the lower end of the cutter head. During operation, the locking block is presseddownwards by a thumb to slide, then, the gear is driven to rotate, the cutter rotates around the axis of the inner handle, and the cutting edge of the cutter cuts corresponding soft tissue in the rotation process of the cutter.
