[0002] Pins are a type of standardized fastener that can be used for static fixed connections or for relative movement with the connected parts. They are mainly used at the hinge joints of two parts to form hinge connections. Pins are usually locked with cotter pins, which ensure reliable operation and easy disassembly.

[0003] Problems with the existing technology: When existing pins are used to connect items, they often fit tightly, resulting in the need for alignment when the connecting parts are plugged in. Especially under restricted conditions, plugging in becomes more difficult. Utility Model Content

[0017] 4. In the utility model, the ball rotates in the second fixed rod fixed at the lower end of the limiting shaft, and the ball can rotate therein when in use. Then the ball and the second fixed rod are interspersed with the interlacing rod, which can play an extension role when in use, and then interspersed on the ball to limit it so that it can only rotate in one direction.

[0018] 5. In the present invention, the steering hole provided on the second fixing rod facilitates the rotation with the following parts during use, and then an extra gap is provided to facilitate adjustment during operation, so that the rotation is smoother.
