Abstract (en)

A wrench includes a handle (10), a clutch (30), a detent, a controller (40), a gear (20) and a C-ring (21). The handle includes an annular head (11) defining a circular space (12), a pothole (13) not overlapping the circular space, a channel (15) for communicating the circular space with the pothole, a recess (14) and an annular groove (16) both defined in a wall of the circular space. The clutch includes two claws (31) put in the recess and a spring (32) put between the claws. Each of the claws includes a toothed face (33) and a rod (34). The claws can easily be put into the recess since the rods can be moved through the channel. A controller is put rotationally in the pothole for moving the rods. The gear is put in the circular space. The gear includes a toothed face for engagement with the toothed face (22) of one of the claws. The C-ring includes an external edge put in the annular groove, and an internal edge for retaining the annular gear in the circular space.
