A barrel (not shown in the drawings) is connected to the front end of the oil outlet passage 12, and a hose of the fuel dispenser is connected to the rear end of the oil inlet passage 11. The stop valve 20 is arranged above the platform 13, when the stop valve 20 is pressed against the platform 13, the liquid passing port 14 is blocked, the oil inlet channel 11 and the oil outlet channel 12 are blocked, so that the fuel gun is in a closed state, when the stop valve 20 moves upwards, the liquid passing port 14 is opened, the oil inlet channel 11 is communicated with the oil outlet channel 12, and fuel in the oil inlet channel 11 can flow into the oil outlet channel 12 through the liquid passing port 14, so that the fuel gun is opened, and the fuel can be injected into a fuel tank of the vehicle through a gun barrel. The upper end of the stem 40 is vertically connected to the check valve 20 and is located below the check valve 20, and the lower end of the stem 40 protrudes out of the gun body 10. The spring 30 is disposed above the check valve 20 for pressing the check valve 20, and when the check valve 20 is not subjected to the upward force of the plunger 40, the spring 30 presses the check valve 20 against the platform 13 to block the liquid passing port 14. The pressing strip 50 is movably connected to the gun body 10, the front portion of the pressing strip 50 is located below the ejector rod 40, when an operator applies force upwards on the pressing strip 50 to enable the front portion of the pressing strip 50 to rotate upwards, the pressing strip 50 pushes against the ejector rod 40 to move upwards, the ejector rod 40 drives the stop valve 20 to move upwards to enable the liquid passing port 14 to be opened and the spring 30 to be compressed, and after the operator removes the force on the pressing strip 50, the spring 30 resets to enable the stop valve 20 to move downwards again to seal the liquid passing port 14. The utility model discloses in: as shown in fig. 2, an elastic body 80 is disposed on the platform 13, a sealing ring 70 is embedded on the elastic body 80, and the stop valve 20 is pressed against the sealing ring 70 by moving downwards.
