Abstract

A ratchet wrench is provided, including a main body, a ratchet, a controlling member, a restriction member and a fixing member. A head portion of the main body has a first face, a second face, a receiving hole, a receiving slot disposed in an inner surface of the receiving hole and an assembling hole. A through hole communicates the assembling hole and the receiving hole. The ratchet is rotatably disposed in the receiving hole. An assembling portion of the controlling member is rotatably inserted in the assembling hole. The restriction member is movably disposed in the receiving slot. The fixing member is disposed in the through hole, and the fixing member is abutted against the controlling member to restrict the assembling member to stay in the assembling hole. Whereby, it is convenient to manufacture and assemble the ratchet.

Description

technical field [0001] The invention relates to a tool, in particular to a ratchet wrench. Background technique [0002] Existing ratchet wrench, as described in the patent No. M462646 of Taiwan, China, mainly has a ratchet part formed on a wrench body, and the ratchet part is provided with an actuating port and a round hole, and a ratchet groove is communicated between them, and a control part is formed by a disc. There is a handle body extending from one end of the disc, and a block is formed at the other end. A U-shaped seat is formed on the top of the block, and a spring is installed at the U-shaped seat, and a limiting gap is recessed between the disc part and the U-shaped seat. , the control part is installed in the round hole, and the U-shaped seat of the control part faces the ratchet groove. One end of the ratchet part is formed with arc-shaped teeth, and the other end is provided with a limiting part. A cylinder protrudes from the limiting part. The ratchet part i...
