High-efficiency convenient skull preparation tool

Abstract

This utility model discloses a highly efficient and convenient skull preparation tool, comprising a lower handle and an upper handle hinged together, both with jaws at the same end and connected by a V-shaped spring. A locking component is located near the jaws on the V-shaped spring. This component includes a rack rotatably connected to the inside of the lower handle, a recessed cavity in the middle of the upper handle, a micro-gear and a micro-ratchet connected to a support shaft within the recessed cavity, and a control shaft rotatably connected thereto. A washer and a micro-torsion spring are fitted around the control shaft, one end of which passes through the upper handle and connects to a hook. The convex surface of the hook abuts against a stop bar. A thumb-and-shoulder stop is located in the center of the top surface of the upper handle. When operating this tool, bringing the handle close deforms the V-shaped spring, pushing the rack and micro-gear to engage, achieving automatic locking without continuous force. Unlocking can be done with one hand. The locking component is ingeniously designed, easy and effortless to operate, and structurally stable, greatly improving the efficiency and comfort of skull preparation.
