[0036] Working principle: when the ball head body 1 works with the ball pin, friction will be generated on the surface of the ball head body 1. At this time, the lubricant liquid in the first liquid channel 400 and the second liquid channel 500 flows out through the liquid guide hole 600 on the liquid outlet 6, and is uniformly applied on the surface of the ball head body 1, forming a lubricating film, which effectively reduces the friction between the ball head body 1 and the ball pin.

[0037] When it is necessary to supplement the lubricant liquid, the pipe cover on the first liquid guide pipe 403 and the second liquid guide pipe 503 is opened, the lubricant liquid is injected into the first liquid channel 400 and the second liquid channel 500 through the liquid guide pipe, and then the pipe cover is closed, so that the lubricating system can normally operate.
