A bolt 8 is threadedly connected to the bottom surface of the pull plate 9, and the bolt 8 is threaded through the pull plate 9 and connected to the bottom surface of the support plate 7. A bushing 10 is placed on the upper end of the pull plate 9, and a piston rod 14 is slidably connected inside the bushing 10. A push rod 5 is sleeved on the upper end of the piston rod 14. The right end of the sleeve pressure plate 3 is rotatably connected to the support plate. A pin 6 is slidably connected to the right end of the sleeve pressure plate 3 on the side wall of the support plate 7. The pin 6 is slidably connected to the side wall of the support plate 7 by passing through the inside of the sleeve pressure plate 3. A groove 12 is provided inside the bottom surface of the sleeve pressure plate 3. A pressure block 13 is fixedly installed on the inner side wall of the groove 12. The pressure block 13 is in contact with the top surface of the push rod 5. The bushing 10 is fastened to the top surface of the pull plate 9 by a fixing bolt. The piston rod 14 is connected to the inside of the bushing 10 by passing through the inside of the pull plate 9. The pull plate 9 is fixedly installed on the side wall of the gas-driven liquid pump body by a fixing bolt. A tension spring 4 is fixedly installed between the push rod 5 and the bushing 10, and the tension spring 4 is sleeved on the outside of the piston rod 14. When the gas-driven liquid pump body is used outdoors, the right end of the sleeve pressure plate 3 is connected to the side wall of the support plate 7. The pin 6 passes through the inside of the side wall of the sleeve pressure plate 3 and is connected to the inside of the side wall of the support plate 7. The bushing 10 is fastened to the top surface of the pull plate 9 by a fixing bolt, and the piston rod 14 is slidably connected to the inside of the bushing 10 by passing through the inside of the pull plate 9. Then, the sleeve pressure plate 3 is pressed down, and the pressure block 13 squeezes the push rod 5.
