Through the coordinated use of structures such as the positioning hole 91, the positioning block 93, and the first spring 94, the moving block 4 can be positioned, and thus the position of the spray gun body 5 can be refined.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , a release mechanism 10 is provided on the flow pipe of the spray gun body 5. The release mechanism 10 includes a diversion plate 101, the diversion plate 101 is fixedly connected to the inner side wall of the flow pipe of the spray gun body 5, a release cylinder 102 is fixedly connected inside the flow pipe of the spray gun body 5, a sliding plate 103 is fixedly connected to the inner top of the release cylinder 102, a sliding cylinder 104 is slidably sleeved on the outer side of the sliding plate 103, a second spring 105 is provided on the outer side of the sliding plate 103, and a friction head 106 is fixedly connected to the lower end of the sliding cylinder 104, the friction head 106 being slidably connected to the release cylinder 102. Through the arrangement of the diversion plate 101, the spraying liquid can be diverted. Under the structures such as the second spring 105 and the friction head 106, the hard impact generated by the fluid stress can be worn.

[0028] The specific implementation process of the present utility model is as follows: During use, through the arrangement of the spray gun body 5, the spraying liquid can be sprayed. When the spray gun body 5 is instantaneously started, it will cause the spraying liquid to instantaneously flow, thereby generating a certain fluid stress impact phenomenon. Under the action of the flow guiding plate 101, the fluid can be guided, so that the spraying liquid contacts the friction head 106.

Under the extrusion of the inner wall of the positioning hole 91, the positioning block 93 can be pushed to move and drive the top plate 92 to move, and the first spring 94 deforms. Finally, the positioning block 93 is separated from the positioning hole 91. Under the action of force, the positioning block 93 moves along the inner side wall of the support table 1. When the positioning block 93 slides into the next positioning hole 91, the first spring 94 restores its deformation to push the positioning block 93 into the positioning hole 91 to limit the movement of the moving block 4, and thus the position of the spray gun body 5 can be precisely controlled and used.
