Abstract:
A ratchet wrench including a holding portion, a neck portion, a switching member, a controlling rod, a blocking member, and a ratchet driving head is disclosed. The neck portion which is located at the top end of the holding portion has a cavity. The cavity has a first recess and an opening. The first recess is used for receiving a compressible elastic member and a ball. The opening is used for receiving and tightly fitting with a bendable elastic member. The switching member has a second recess to hold the bottom of the bendable elastic member, and the switching member has two adjacent arc grooves at its bottom. The controlling rod links the switching member to shift the switching member in the cavity to allow the ball to be pressed into one of the arc grooves. The controlling rod can be applied to shift, rotate or both shift and rotate the switching member in the cavity.
