Abstract (en)

[origin: WO2022011631A1] A fastening tool includes a motor assembly (20), a drive mechanism connected to the motor assembly and adapted to drive a piston; and an energy accumulating mechanism that is connected to a striking element (38) suitable for striking a workpiece. The energy accumulating mechanism contains a driven member (36). The drive mechanism further contains a crank assembly (28) connected between the motor assembly (20) and the driven member to transform a rotational force from the motor assembly (20) to a linear motion of the driven member(36). With the crank assembly the fastening tool eliminates gear meshing parts in its motion conversion mechanism, which does not only simplify the structure, saves cost, but also prolongs the product life of the fastening tool.
