[0002] When repairing groundwater, it is necessary to use an injection device to inject the repair agent into the groundwater. For example, Chinese utility model patent CN218656090U discloses an injection device for groundwater repair agent. Water is injected into the water storage tank through a water inlet pipe. After the injection device body completes the injection of the agent, the injection tube body is taken out of the soil layer. At this time, the hydraulic pump is turned on. Under the pressure of the hydraulic pump, the water in the water storage tank is transported into the drain pipe through the pumping pipe, and then flows into the annular pipe. Multiple conical nozzles are all facing the direction of the injection tube body. The annular pipe The water inside is sprayed toward the outer surface of the injection tube body through multiple conical nozzles to clean the mud and sand stains on the surface, thereby achieving the effect of convenient and timely cleaning; as the injection tube body is taken out upward, the arc-shaped scraper can scrape off some muddy stains on the surface, making it easier for the conical nozzle to spray water for cleaning, so that the outer surface of the injection tube body can be cleaned more cleanly. When there are fewer stains on the outer surface of the injection tube body and the arc-shaped scraper is not needed, move the arc-shaped scraper upward with force to make the two L-shaped plates slide out from the inside of the L-shaped groove, and then open the buckle to remove the arc-shaped scraper.

[0003] Although the above-mentioned prior art can clean the stains on the surface of the syringe body, the tip of the syringe body cannot be cleaned, so that the tip of the syringe body still needs to be cleaned manually. Utility Model Content
