A fastener tool which contains a motor, a drive mechanism connected to the motor and adapted to drive a piston, and a locking module. The locking module includes a rotating member coupled with the drive mechanism and adapted to rotate with a spindle and define a rotation axis; and a receiving member adapted to engage with the rotating member at and engaging portion. The rotating member includes a latch and a biasing member, wherein the biasing member moveably supports the latch in a direction substantially perpendicular to the rotation axis. Therefore, the locking module provides a locking mechanism that prevents back driving of the fastener tool that increases the lifespan and efficiency of the tool.

A powered fastener driver includes a cylinder and a drive piston within the cylinder being acted on by a driving force resulting from a pressure differential. The powered fastener further includes a drive blade coupled to the drive piston and operable to drive a fastener, and an adjustable valve for selectively introducing air from ambient atmosphere into the cylinder, thereby changing the pressure differential acting on the drive piston. By adopting a self-contained vacuum generating means as described above, the present invention does not rely on any external vacuum source and powered fastener driver can be used and carried with conveniently.
