[0045] Step 4. Securely fix the device body 1 to the equipment platform through the through groove 11-3 of the base 11, connect the air pipe group of the three sets of cylinders 13 connected in series through the air pipe connector 111 and the air pipe 112 to the air source, and adjust the cylinders 13 to the non-ejected state.
