fifthly, when the distance between the upper end supporting disc (3) and the supporting rotating disc (2) needs to be adjusted, the electric cylinder (103) is started, the telescopic rod (606) of the electric cylinder (103) contracts to drive the pressing block (104) to reset, the pressure of the supporting block (608) is removed, the driving rod (602) and the driving shaft (6) are decoupled, when the driving shaft (6) is kept in a static state, the second motor (66) is driven to drive the driving rod (602) to rotate, the position adjustment of the upper end supporting disc (3) is realized, and the distance adjustment between the upper end supporting disc (3) and the supporting rotating disc (2) is further realized.
