The working principle of the slip shaft is roughly divided into two types. One is the same principle as the air shaft, which uses the expansion and contraction of the air bag to control the tightness of the slip ring and meet the reasonable tension requirements required by customers. The simplest one is that the strip-type air shaft is consistent with the principle of this kind of slip shaft. The principle of this structure slip shaft is to use the promise dry strip groove on the shaft center to install the air bag, and then match it with a slip ring. It is a high quality slip shaft.
