Abstract

An impact driver (1), comprising a housing (20), a motor (21), a main shaft (23) and an impact mechanism, the impact mechanism comprising an anvil (10) and a hammer (25) which is both rotationally and axially movable relative to the anvil (10), a front end of the anvil being provided with a chuck portion for receiving a front-end tool, the chuck portion being provided with an axially extending insertion hole (14), and a rear end of the anvil being provided with a receiving opening (12) for receiving a front end of the main shaft, wherein the insertion hole (14) and the receiving opening (12)are connected to each other. Thus, if the front-end tool breaks and a broken part is jammed in the insertion hole (14), the broken part can be pushed out of the insertion hole (14) using a maintenance tool, so that there is no need to scrap the entire anvil; thus, the convenience of maintenance is increased while the cost of maintenance is greatly reduced.
