Abstract

Disclosed is a tool handle (20) having an inner safety core (230), comprising an outer housing and an inner cavity, wherein the inner cavity is filled with the safety core made of a lightweight and flexible material. Also disclosed is a hand tool comprising the tool handle. The tool handle in use can absorb a vibration and reduce a counterforce to alleviate fatigue of an operator. Also, the tool handle uses less material than the existing hollow tool handle, is more lightweight and high-strength, and is ensured not to be broken into halves when broken, thus being more safe and reliable.

Description

technical field [0001] The invention relates to a tool handle, in particular to a tool handle with a safety inner core and a hand tool including the tool handle. Background technique [0002] Existing hand tools generally include a tool head and a tool handle connected with the tool head. Tool heads mainly include axes, hammers, hoes and so on. Tool handles are generally made of engineering plastics, metal or wood. [0003] Chinese Utility Model Patent No. 201420601467.7 provides a hand tool with a hollow bent handle, including a tool head and a tool handle, the tool head is connected to the tool handle, the tool handle is a hollow bent handle, and the tool The head and the tool handle are integrally connected by injection molding. Although the above-mentioned hand tools with hollow curved handles are light in weight, comfortable to use and high in efficiency, their safety cannot be fully guaranteed, especially in case the tool handle breaks due to abnormal use or other r...
