Abstract
A ratchet wrench includes a ratchet unit which has a ratchet tube with a reception hole. A collar is connected to one side of the head and has a slit defined radially through the collar. An engaging member has a first end thereof fixed to the collar, and a second end of the engaging member extends through the slit. The second end of the engaging member is partially located within the through hole of the collar and located above the reception hole of the ratchet tube. An operation ring is mounted to the collar and connected the engaging. A C-clip is mounted to the outer periphery of the collar. When the operation ring is rotated, the second end of the engaging member is pushed to move within the through hole of the collar to position a socket located in the reception hole of the ratchet tube.
