<p>A multiple function power tool includes a motor (50), a gear-box (05), a transmission part, a module set, an arc element (30) and a control circuit, wherein the control circuit connects with the input end of the motor (50), a turning end of the motor (50) connects with the input end of the gear-box (05), an output end of the gear-box connects with the transmission part, an end of the arc element (30) sleeves on the transmission part, the module set is provided between the other end of the arc element (30) and transmission part, and the transmission part is a ball screw structure. The power tool has a simple structure and lower cost; the mechanical efficiency is improved and the energy is saved by the ball screw structure; the different functions, e.g. punch, shear and compression joint can be achieved by replacing the module set.</p> |
