The invention relates to a handheld power tool (1), including: a mobile element (100) and a stationary element (102) a rotatable actuator a ball nut (200) a ball screw (202) having a first end (202a) connected to the mobile element (100) and a universal joint (10, 12, 14) arranged so as to be driven by the rotatable actuator and so as to rotate the ball nut (200) on said ball screw (202) in order to move the ball screw (202), and thus the mobile element (100), relative to the stationary element (102). The universal joint can be advantageously retained inside two concentric spherical bearings (50a, 60a, 70a, 80a), thus making it possible to take up the axial forces in two directions. It is thus possible to eliminate any radial force on the ball screw (202) and have angularly variably rotational output.
