Specifically, traditional pin connection structures usually require the use of complex tools during installation and disassembly, which is cumbersome and inefficient. In addition, during long-term use of the pin, due to the lack of effective lubrication measures, it is easy to cause increased wear between the pin and the pin hole, affecting the stability and service life of the connection.

[0007] Preferably, there are two oil seepage holes, which are symmetrically distributed about the oil storage cavity, and a rubber sheet is fixed on the end plate of the pin body, and the rubber sheet is an annular plate.

[0008] Preferably, a through hole is formed on the surface of the baffle bar, and the positioning handle passes through the through hole.

[0009] Preferably, a slot is provided on the rod body of the positioning plug handle, and the slot is an annular slot.

[0010] There are two card slots, and the surfaces of the introduction port and the installation port are both sleeved and fixed with rubber clamps, the rubber clamps and the card slots correspond one to one, and after one end of the positioning handle is inserted into the introduction port, the rubber clamp is inserted into the corresponding card slot.

[0011] Preferably, the installation port is a "T"-shaped round hole, one end of the installation port is provided with an internal thread, the positioning handle is a "T"-shaped round rod, one end of the positioning handle is provided with an external thread, and the external thread and the internal thread are matched and connected.
