Further, the cylinder clamp mechanism 100 may include a single acting finger cylinder 101 and a return spring (not shown); the reset spring is arranged between the two clamping jaws of the finger cylinder 101 and used for driving the two clamping jaws to reset. The clamping process is that a compressed air pressure supply source such as an air pump provides compressed air or extracts air for the finger cylinder 101 through the air claw rotary joint 103 so as to drive the two clamping jaws of the finger cylinder 101 to overcome the elastic force of the return spring to draw together in an opposite direction, and the clamping action is completed. When the clamping jaw is loosened, the two clamping jaws are opened and reset through the elastic force of the reset spring to complete the loosening action. Of course, the return spring in the present application may also be directly installed in the cylinder block of the finger cylinder 101, and is used for providing the return elastic force to the piston in the cylinder block, which is not limited in particular.

Therefore, the number of the driven pulleys 204 can be designed to be one more than that of the finger cylinder 101; the excessive driven pulleys 204 can be rotatably mounted at the other end position of the top of the rotating plate 304 and are distributed on the same second straight line with the driving pulleys along the length direction of the rotating plate 304; wherein the first straight line and the second straight line are distributed at intervals; i.e. such that the first straight line does not coincide with the second straight line.
