Abstract: The present invention discloses a wrench holder comprising a main frame, a hand grip, a slidable fastener, two knobs and a cover plate. There is a plurality of recesses defined on the main frame for wrenches to be held. The hand grip is rotatably allocated at the bottom of the main frame, and the slidable fastener is movably applied at the bottom of the main frame as well to limit the hand grip revolving against the main frame. The cover plate provides the wrenches held within the main frame to be sheltered. The wrench holder of the present invention is designed to improve protection for wrenches and convenience for users.

Abstract: The present invention discloses a ratchet wrench, which includes a body, a driving head, a fixing disk and a rotatable member. The body has a ring-shaped head with internal teeth therein. The driving head is located in the ring-shaped head and has a top portion which has a reception recess and a pawl is located in the reception recess. The pawl has engaging teeth on two ends of the front thereof and two curved surfaces are formed on the back of the pawl. A spring is located in the reception recess so as to bias the back of the pawl. The rotatable member is located on the top of the ring-shaped head and has two driving pins which shift the spring to pivot the pawl such that the engaging teeth in one of the two ends of the pawl are engaged with the internal teeth to control the driving head to rotate in one direction.
