[0025] When the utility model is used, the operator first places the fire extinguisher bottle between the two inclined plates 14, and then places the fire extinguisher base on the front side of the round table 35, and starts the first motor 15. The output shaft of the first motor drives the first pulley 16 to rotate, and the first pulley 16 drives the second pulley 17 to rotate through the belt 18. The second pulley 17 synchronously drives the first screw 10 to rotate, so that the bottom plate 11 moves upward, and the bottom plate 11 drives the connecting rod 13 and the inclined plate 14 to move upward synchronously through the vertical rod 12, and drives the inclined plate The fire extinguisher bottle body on the upper side of 14 moves upward, so that the fire extinguisher bottle body is horizontally aligned with the base, and the first electric telescopic rod 22 is started. The output end of the first electric telescopic rod 22 pushes the second motor 23 to move forward, so that the base on the front side of the round table 24 abuts against the fire extinguisher bottle body, and then the second motor 23 and the welding gun 21 are started synchronously. The second motor 23 synchronously drives the base and the fire extinguisher bottle body to rotate, and at the same time, the welding gun 21 welds the intersection of the fire extinguisher bottle body and the base, which reduces the labor intensity of the operator and improves the welding efficiency;

[0026] The utility model drives four inclined plates to move up and down by a first motor, thereby adjusting the upper and lower positions of the fire extinguisher bottle body so as to align them with the base; and drives the fire extinguisher bottle body and the base to rotate simultaneously by a second motor, so that a welding gun welds the connection between the fire extinguisher bottle body and the base, thereby realizing automatic welding, improving production efficiency and ensuring product quality.
