摘要： A ratchet tool includes a head portion, a ratchet mechanism, and a pawl control mechanism. The ratchet mechanism includes a gear wheel and a pawl in tooth engagement. The gear wheel is rotatably mounted on the head portion. The pawl is movably mounted on the head portion. The pawl control mechanism includes a pusher urged by an elastic member. The pusher includes a first end against the pawl and a second end against the elastic member. The elastic member is selectively compressed by the pusher. The elastic member includes at least one limiting portion of a first internal diameter against the second end of the pusher. The elastic member includes a plurality of compressible portions and the compressible portion adjacent to the at least one limiting portion is of a second internal diameter. The first internal diameter is less than the second internal diameter.

摘要： A one-way torque adjustable screwdriver comprises a body and a polygonal elastic member disposed inside the body. A torque transmission device and a torque adjusting device are mounted on two ends of the polygonal elastic member, respectively. A drive rod is connected to the torque transmission device. Driving the torque adjusting device to move can change a length of the polygonal elastic member, thus change an acting force of the polygonal elastic member exerted on the torque transmission device, change an output torque provided by the drive rod, and thus achieve the effect of easy operation.

摘要： 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. In addition, the corresponding hook portion and shaft can be combined together through the simple penetrating and hooking actions, and the crossing and rotating actions can separate the two box bodies from each other in the state when the tool box is opened, so that the effects of the simple and convenient operations are achieved.
摘要翻译： 具有快速释放结构的工具箱包括：第一箱体，其具有与第一钩部和第一轴一体形成的一侧; 以及具有与第二钩部和第二轴一体形成的一侧的第二箱体。 第一钩部钩住第二轴，第二钩部钩住第一轴。 因此，第一箱体和第二箱体可以组合在一起并形成可开启和闭合的状态。 因为第一箱体，第一钩部和第一轴可以一体地形成为与由第二箱体，第二钩部和第二轴构成的结构形成相同的结构，该第二箱体也可以一体形成 ，可以实现简化结构的目的和效果。 此外，相应的钩部和轴可以通过简单的穿透和钩挂动作组合在一起，并且交叉和旋转动作可以在工具箱打开的状态下将两个箱体彼此分离，从而使效果 实现了简单方便的操作。

摘要： 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.

摘要： 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.
