摘要： A ratchet wrench includes first recess in the function end thereof and a second recess is defined in the inside of the first recess. A ratchet wheel is located in the first recess, and a pawl and a resilient member are located in the second recess. The resilient member is connected between the pawl and the inside of the second recess. The resilient member biases the pawl to be engaged with the ratchet wheel. A C-shaped restriction member is engaged with the first recess and has a rod which is inserted into the second recess. A space is defined between the inside of the first recess and the rod. The second end of the resilient member is located in the space so as to position the resilient member in the second recess.

摘要： A pawl structure of ratchet wrenches has multiple engaging teeth, a first recess and a second recess. The engaging teeth include first teeth at the mediate portion and second teeth are respectively located at two ends of the engaging teeth. The tips of the first teeth are located on a first curve which has a center and a central line extends through the center and intersects the first curve. The tips of the second teeth are located on a second curve which gradually leaves from the center of the first curve along with the second curve extending away from the central line. The first recess is located corresponding to the central line and the first teeth. The second recess is located corresponding to the second teeth.

摘要： An open wrench includes a body having a mounting hole defined therethrough. Two first faces and two second faces are respective defined in the inside of the mounting hole. The two first faces and the two second faces are located along four consecutive sides of an imaginary hexagonal body. Each first face has at least two teeth defined therein. Five curved faces are defined in the inside of the mounting hole and located corresponding to five corners of the imaginary hexagonal body. Each of the first and second faces has a contact face and each contact face is connected between two adjacent curved faces. The length of each contact face is 0.5-0.65 of the length of each side of the imaginary hexagonal body.

摘要： The present invention relates a one-direction ratchet wrench, which has a driving head with a first cavity and a second cavity. There are walls located on the top and the bottom portions of the second cavity, and a pin hole is extended from the second cavity to the walls. A ratchet wheel is rotatably mounted in the first cavity, and there is a plurality of ratchet teeth in the outer periphery of the ratchet wheel and a receptacle formed in the middle to receive and drive workpieces. A pawl is located in the second cavity and one of its sides has a plurality of teeth engaged with the ratchet teeth. A pin is inserted in a pin hole for an elastic assembly to hitch on. The elastic assembly has a first elastic element and a second elastic element. One end of the second elastic element links to the pawl and the other end links to the first elastic element. The first elastic element hitches on the pin and one of its ends sticks against the inner wall of the second cavity. Thus, the present invention is able to effectively control workpieces being driven in one-direction.
