[0037] The device further comprises a compressed air pipeline 6 connected to the pneumatic motor, which is used to deliver compressed air to drive the operation of the pneumatic motor. A pressure regulating valve is arranged on the compressed air pipeline to adjust the pressure of the compressed air entering the pneumatic motor. Specifically, the first support shaft and the second support shaft are hollow structures, and the compressed air pipeline communicates with the outside air through the inside of the first support shaft or the second support shaft.

[0038] The outer cylinder is sleeved on the first end cover and the second end cover, and the outer cylinder is fixedly connected to the first end cover and the second end cover through the second bolts, so that the outer cylinder drives the first end cover and the second end cover to make a circular motion.
