  • Patent number: 11994178
    Abstract: A universal joint includes a socket member and a driving member. The socket member includes a receiving hole, and an inner periphery of the receiving hole is formed with first evading portions and first abutting portions staggered with each other to cause the first abutting portions not connected to each other. Each first abutting portion is provided with a first abutting face, a second abutting face, and an adjacent edge formed between the first abutting face and the second abutting face. One side of the adjacent edge forms an adjacent edge angle being greater than 177 degrees and less than 180 degrees. The driving member includes a rounded base arranged in the receiving hole and a driving column opposite to the rounded base.

  • Patent number: 11965563
    Abstract: An elastic short-pin type universal joint includes a first base, a second base, a jointer, a first elastic member, two second elastic members, and four short pins. The first base engages the second base to form a space therebetween. The jointer is received in the space between the first and the second bases. The jointer has a first bore passing through the jointer, a second bore, and a third bore. The first elastic member is received in the first bore of the jointer, and the second elastic members are received in the second bore and the third bore. The short pins are urged by ends of the first elastic member and the second elastic members to press the first base and the second base respectively. As a result, the first base is able to rotate related to the second base in all directions.

  • Patent number: 10421175
    Abstract: An anti-theft rack includes a rack frame supporting at least one retaining device. The at least one retaining device is configured to retain a socket tool and includes a seat mounted on the rack frame, a sliding member slidably engaged with the seat, and a retaining member disposed between the seat and the sliding member. The seat includes a shaft portion and the sliding member is movably mounted on the shaft portion. The shaft portion includes a first recessed portion and a second recessed portion of different depths adapted to receive the retaining member. The retaining member is selectively disposed in the first and second recessed portions in response to movement of the sliding member. Further, a position limiter is releasably disposed between two terminal positions of a moving path of the sliding member and configured to prevent the sliding member from the first position to the second position.

  • Publication number: 20150136763
    Abstract: A tool box with a quick release structure includes a first box body having one side integrally formed jointly with a first hook portion and a first shaft; and a second box body having one side integrally formed jointly with a second hook portion and a second shaft. The first hook portion hooks the second shaft, and the second hook portion hooks the first shaft. Thus, the first box body and the second box body can be combined together and form openable and closeable states. Because the first box body, the first hook portion and the first shaft can be integrally formed as a structure form the same as the structure form constituted by the second box body, the second hook portion and the second shaft, which can also be integrally formed, the object and effect of simplifying the structure can be achieved.

  • Patent number: 8869658
    Abstract: In a multi-function tool structure, a body and a work rod are pivotally connected together and can form a folded and retracted state. Moreover, an elastically movable press button is disposed on the body and can link up a positioning pin movably inserted into the work rod. Thus, pressing the press button can release a lock between the work rod and the positioning pin so that the work rod is swingable, while releasing the press button can lock the positioning pin and the work rod together again. Thus, the work rod and the body can be folded and retracted to facilitate the storage and carrying. After the work rod is developed, it can form multiple included angles with respect to the body so that the requirements of different operation angles can be satisfied.

  • Patent number: 8113092
    Abstract: A push-type ratchet wrench may be easily operated. At least one end of a handle has a head, in which a driving body for rotating a workpiece and an engaging block capable of selectively switching the rotation direction of the driving body are provided. Also, a control member for actuating the engaging block is provided on the head. The control member includes a base disposed in the head, and an actuating block pivotally mounted on the base. The actuating block has an actuating sheet passing through the base and extending toward the engaging block. A clamping slot is formed at a location corresponding to the engaging block so that the actuating sheet can be clamped by the engaging block, and the user can press the actuating block leftward/rightward to achieve the object of switching and to prevent the conventional problems of easily breaking and uneasily actuating.
