[0026] The working principle of this utility model is as follows: At the start of operation, the adjusting screw is adjusted, and the piston retracts along the adjusting screw under the elastic force of the spring. After adjusting to the required injection volume, the regulating valve is adjusted. The regulating valve is used to connect to external air compressor equipment to compress air and control the frequency. After adjustment, the injection channel and regulating chamber are emptied. Then, the regulating valve is opened to inject air, pushing the piston to move. The piston compresses the spring. After compression to the desired level, the regulating valve releases pressure and exhausts air. The spring resets, causing the piston to retract. Simultaneously, the one-way valve closes. When valve two opens, the piston's movement creates a vacuum between the sliding cavity and the injection channel, causing oil to flow from check valve two into the sliding cavity and injection channel, entering a state ready for injection. During the injection action, check valve two closes, check valve one opens, and the regulating valve opens to inject compressed air. The compressed air pushes the piston forward, which in turn pushes the push rod, forcing the oil in the sliding cavity and channel one out. The oil is then ejected from check valve one. After ejection, the regulating valve, piston, check valve one, and check valve two reset to enter the oil storage phase, completing the entire process.
[0027] This invention uses an adjustment structure to adjust the space of the adjustment cavity, thereby adjusting the reset distance of the piston assembly.

Furthermore, by setting up the injection channel and adjustment cavity, oil-gas separation is achieved, preventing the inflow of injection gas and the formation of oil mist, ensuring injection quality, and preventing the splashing of oil mist from affecting workshop operators, thus improving protection.
