Figure 3-Figure 6 The alcohol in the alcohol tank 44 can flow into the interior of the piston cylinder 39 in a one-way quantitative manner through the one-way valve 8. When the first contact rod 18 continues to move after contacting the first contact frame 21, the purpose of contacting the piston rod 41 in the piston cylinder 39 can be achieved. The piston rod 41 drives the piston plate 40 to move in the piston cylinder 39, and the quantitative alcohol inside can be transported to the plurality of nozzles 43 fixed on the cleaning seat 28 through the pipeline for spraying. The ninth spring 42 accumulates force, which is convenient for wetting the cleaning sponge 31, and the dial body 4 can be removed. The stains and grease on the surface can be removed to improve the cleaning effect. The quantitative spraying of alcohol can reduce the excessive use of alcohol and avoid waste. Secondly, the volatilization speed can be increased to avoid alcohol residue in the welding process and affect the welding quality. When the welding gun 7 is welding, the first resistance rod 18 is resisted and continues to move horizontally, the ninth spring 42 stops storing force, and one end of the first resistance rod 18 pushes the piston cylinder 39 to move, prompting the mounting plate 46 fixed under the piston cylinder 39 to slide on the third slide rod 45, and the tenth spring 47 stores force.
