A lead screw 86 is connected to the inside of the nut pair 85, and one end of the lead screw 86 abuts against the outer wall of the material cylinder 7. The bevel gear 83 can be driven to rotate by rotating the bevel gear ring 81, and the nut pair 85 can be driven to rotate by the rotation of the bevel gear 83, thereby realizing the displacement of the lead screw 86, and then the clamping and positioning of the material cylinder 7 is realized through the synchronous displacement of the lead screw 86, thereby ensuring the stability of the material cylinder 7.

[0029] Furthermore, a material receiving barrel 6 is placed on the upper surface of the vehicle body 1 , and the material receiving barrel 6 corresponds to the bottom of the spray gun 5 .
