发明名称 Ratchet wrench with rotatable driving head
摘要 A ratchet wrench includes a body, a driving head, a control member and a resilient member. The body includes a handle and a Y-shaped extension. The driving head is pivotably connected to the Y-shaped extension by two pivots and an inner groove and a recess are respectively defined in the inside of the Y-shaped extension. The inner groove accommodates the C-shaped plate of the control member and the resilient member is received in the recess. The C-shaped plate has engaging teeth defined in distal ends thereof and the pivots each have ratchet teeth which are engaged with the engaging teeth by moving the control member so as to control the rotation of the driving head relative to the body.
