A piston ring 5 is machined on the piston 2. The piston ring 5 is sealed to the piston chamber by a sealing element 6. A sealing ring 7 is disposed at the opening of the piston chamber. The sealing ring 7 is fixed to the piston chamber by set screws. The side of the sealing ring 7 is sealed to the piston chamber and the piston 2 by sealing elements 8 and 9, respectively. An air inlet 10 and an air inlet 11 are machined on the piston chamber, located on opposite sides of the piston ring 7. Compressed gas is introduced through the air inlet 10 and air inlet 11, causing the piston 2 to slide. An end cap 12 is installed at one end of the cylinder liner 1. The end cap 12 is connected to the cylinder liner 1 by screws, and the end cap 12 presses against the sealing ring 7.

[0019] The sliding sleeve 3 slides within the sliding sleeve cavity. A sealing element 13 is provided within the sliding sleeve cavity and is sealed to the sliding sleeve 3. One end of the sliding sleeve 3 is fixed to the piston 2 by a snap ring 14. The sliding sleeve 3 is sealed to the piston 2 by a sealing element 15. The piston 2 has a mounting groove, and the sliding sleeve 3 is placed in the mounting groove. A snap ring groove is machined in the mounting groove, and the snap ring 14 is connected in the snap ring groove. The sealing element 15 is installed on the side wall of the mounting groove.

[0020] The rotating sleeve 4 is rotatably connected to the rotating sleeve cavity through a bearing component 1. The bearing component 1 includes two ball bearings, which are sleeved on both ends of the rotating sleeve 4. An end cap 2 16 is installed on the other end of the cylinder sleeve 1, which blocks the bearing component 1. One end of the rotating sleeve 4 extends out of the cylinder sleeve 1 and is connected to a drive wheel 17. The drive wheel 17 is installed on the extended end of the rotating sleeve 4 through a key block. A shoulder is machined on the rotating sleeve 4 to block the drive wheel 17.
