ABSTRACT:
A ratchet wrench includes a wrench body, a ratchet wheel, a direction control mechanism, a drive member, a ball, and a quick release mechanism. The quick release mechanism includes a bolt, a movable rod, a press knob, and an elastic member. Thus, the socket is mounted on and detached from the driving head of the drive member easily and rapidly, thereby facilitating a user mounting the socket on the driving head of the drive member and detaching the socket from the driving head of the drive member.
