Abstract
A multi-impact hand tool comprises a sleeve, a tool head, a movable rod, a spring and an impact block. With only one impact operation, the multi-impact hand tool can provide a multi-impact effect, thus improving the working efficiency. In addition, the impact force can be directly transferred to the tool head for performing the chiseling operation, thus improving the working efficiency.
