A piston air plate 9 and a piston oil plate 10 are fixedly installed on the two rotating shafts 8 respectively. The transfer box 2 is provided with a rotation drive assembly for driving the two rotating shafts 8. The cylinder cavity 3 in the cylinder body 1 is connected to the air cavity 6 and the oil cavity 7 of the transfer box 2 by an air supply pipe 18 and an oil supply pipe 19 respectively. The piston air plate 9 is provided with a gas flow channel assembly for connecting to the air supply pipe 18, and the piston oil plate 10 is provided with a hydraulic oil flow channel assembly for connecting to the oil supply pipe 19.

[0021] Furthermore, the rotation drive assembly includes a first gear 15, a second gear 16, and a motor 17. The first gear 15 and the second gear 16 are respectively fixedly installed at one end of the two rotating shafts 8 that extend rotatably out of the transfer box 2. The first gear 15 and the second gear 16 mesh with each other. The motor 17 is provided on one side of the transfer box 2. The output shaft of the motor 17 extends rotatably into the air chamber 6 and is fixedly connected to the corresponding rotating shaft 8. This facilitates the opposite rotation adjustment of the piston air plate 9 and the piston oil plate 10 inside the transfer box 2.

[0022] Furthermore, the gas flow channel assembly includes an intake flow channel 11 and an exhaust flow channel 12. The piston disc 9 is provided with an intake flow channel 11 and an exhaust flow channel 12 respectively. Both the intake flow channel 11 and the exhaust flow channel 12 are adapted to the gas supply pipe 18, which facilitates the intake or exhaust operation of gas in the cylinder 1.

[0023] Furthermore, the hydraulic oil flow channel assembly includes an oil outlet channel 13 and an oil inlet channel 14. The piston oil plate 10 is provided with an oil outlet channel 13 and an oil inlet channel 14 respectively. Both the oil outlet channel 13 and the oil inlet channel 14 are adapted to the oil supply pipe 19, which facilitates the oil inlet or outlet operation of the hydraulic oil in the cylinder 1.

[0024] Specifically, an intake pipe 20 and an exhaust pipe 21 are respectively installed on both sides of the air chamber 6 on the transfer box 2. The intake pipe 20 is adapted to the intake flow channel 11, and the exhaust pipe 21 is adapted to the exhaust flow channel 12. When the intake flow channel 11 on the piston plate 9 is connected to the air supply pipe 18 and the intake pipe 20, it facilitates the entry of gas into the cylinder chamber 3, so that the upper chamber of the piston plate 4 in the cylinder chamber 3 generates high pressure. When the exhaust flow channel 12 on the piston plate 9 is connected to the air supply pipe 18 and the exhaust pipe 21, it facilitates the discharge of gas from the cylinder chamber 3, so that the upper chamber of the piston plate 4 in the cylinder chamber 3 generates low pressure.

[0025] Specifically, the oil chamber 7 on the transfer box 2 is connected to the oil drain pipe 22 and the oil inlet pipe 23 on both sides respectively. The oil drain pipe 22 is adapted to the oil outlet channel 13, and the oil inlet pipe 23 is adapted to the oil inlet channel 14. When the oil outlet channel 13 on the piston oil plate 10 is connected to the oil supply pipe 19 and the oil drain pipe 22, it is convenient for the hydraulic oil in the cylinder chamber 3 to be discharged. When the oil inlet channel 14 on the piston oil plate 10 is connected to the oil supply pipe 19 and the oil inlet pipe 23, it is convenient for the hydraulic oil to enter the cylinder chamber 3.

[0026] In operation: When the cylinder body 1 is running, the starting motor 17 drives the corresponding rotating shaft 8 to rotate. Since the first gear 15 and the second gear 16 mesh, they simultaneously rotate in opposite directions, causing the piston disc 9 to rotate in the air chamber 6 of the transfer box 2. Simultaneously, the piston oil disc 10 rotates in the oil chamber 7 of the transfer box 2. When the exhaust channel 12 on the piston disc 9 is connected to the air supply pipe 18 and the exhaust pipe 21, the oil inlet channel 14 on the piston oil disc 10 is connected to the oil supply pipe 19 and the oil inlet pipe 23. This allows hydraulic oil to enter the lower chamber of the cylinder cavity 3 within the cylinder body 1 through the oil inlet pipe 23, the oil inlet channel 14, and the oil supply pipe 19. Simultaneously, the gas in the upper chamber of the cylinder cavity 3 is discharged through the air supply pipe 18, the exhaust channel 12, and the exhaust pipe 21, causing the cylinder... Low pressure is generated in the upper chamber of cylinder 3, which facilitates the rapid rise of piston plate 4 within cylinder 3, completing the rapid lifting operation of push rod plate 5. When the push rod plate 5 is lowered, the motor 17 is started to rotate in the reverse direction, connecting the air intake channel 11 on piston gas plate 9 with air supply pipe 18 and air intake pipe 20. At the same time, the oil outlet channel 13 on piston oil plate 10 is connected with oil supply pipe 19 and oil discharge pipe 22, allowing gas to quickly enter the upper chamber of cylinder 3 through air intake pipe 20, air intake channel 11, and air supply pipe 18. This generates high pressure in the upper chamber of cylinder 3, rapidly pushing piston plate 4 to move rapidly downward within cylinder 3, facilitating the rapid discharge of hydraulic oil in the lower chamber of cylinder 3 through oil supply pipe 19, oil outlet channel 13, and oil discharge pipe 22, thereby quickly completing the lowering operation of push rod plate 5.

[0027] In summary, by installing a piston air plate 9 and a piston oil plate 10 in the transfer box 2, and by rotating the drive assembly to connect the exhaust flow channel 12 or intake flow channel 11 on the piston air plate 9 with the exhaust pipe 21 or intake pipe 20, and simultaneously connecting the oil inlet flow channel 14 or oil outlet flow channel 13 on the piston oil plate 10 with the oil inlet pipe 23 or oil outlet pipe 22, the gas in the upper chamber of the cylinder cavity 3 in the cylinder body 1 is quickly discharged, generating low pressure. This facilitates the rapid entry of hydraulic oil into the lower chamber of the cylinder cavity 3 through the oil inlet pipe 23, oil inlet flow channel 14, and oil delivery pipe 19, completing the rapid lifting operation of the push rod plate 5. Simultaneously, the gas... The air enters rapidly into the upper chamber of cylinder 3 through intake pipe 20, intake passage 11 and air supply pipe 18, generating high pressure in the upper chamber of cylinder 3. This rapidly pushes piston plate 4 downward within cylinder 3, facilitating the rapid discharge of hydraulic oil from the lower chamber of cylinder 3 through oil supply pipe 19, oil outlet passage 13 and oil drain pipe 22, thereby quickly completing the descent of push rod plate 5. In this case, cylinder 1, through a combination of pneumatic and hydraulic oil entering and exiting cylinder 3, can quickly complete the lifting or lowering of push rod plate 5 on cylinder 1, achieving precise control of the lifting and lowering of push rod plate 5 on cylinder 1, and reducing the possibility of cylinder 1 retraction.
