A limiting groove is formed on the surface of the rectangular block 6. A micro motor 7 is fixedly installed inside the limiting groove. A lead screw 8 is arranged at the end of the micro motor 7. A guiding block 9 is sleeved outside the lead screw 8. A wire bundling assembly 10 is movably installed on the front of the guiding block 9. The wire bundling assembly 10 includes a connecting block 1001. A limiting port is formed on the front of the connecting block 1001. A micro reset spring 1002 is fixedly connected to the inner side wall of the limiting port. An arc-shaped fixing plate 1003 is fixedly connected to the end of the micro reset spring 1002.

[0027] In this embodiment, an anti-slip pad is adhesively bonded to the surface of the arc-shaped fixing plate 1003. The anti-slip pad is made of rubber material. By providing the anti-slip pad, the contact friction between the arc-shaped fixing plate 1003 and the connecting pipe 5 is increased, thereby improving the clamping stability of the wire bundling assembly 10 on the connecting pipe 5.

[0028] In this embodiment, a docking hole 17 is formed in the front surface of the guide block 9, and a plug rod 1004 is fixedly connected to the back surface of the connecting block 1001. By providing the plug rod 1004 and inserting it into the docking hole 17, the wire bundling assembly 10 can be quickly docked with the guide block 9, and the disassembly and assembly are convenient.

[0029] In this embodiment, magnetic attraction sheets 18 are provided at both the inside of the docking hole 17 and the end of the plug rod 1004. The sizes of the two groups of magnetic attraction sheets 18 match each other. By providing the magnetic attraction sheets 18, the wire bundling assembly 10 can be stably installed on the guide block 9 and is not likely to fall off during use.

When using the spray gun, if it accidentally falls, due to the action of the elastic cord 12, the spray gun will not fall, so that the spray gun will not be damaged.

[0031] Embodiment Two;

[0032] On the basis of Embodiment One, a preferred embodiment of the powder coating electrostatic spray gun provided by the present invention is as Figures 1 to 4 shown:

[0033] In this embodiment, a plurality of ventilation holes 14 are formed in the surface of the elastic band 13, and a cavity is formed inside the elastic band 13. A water bag 16 is filled in the cavity. By providing the ventilation holes 14 and the water bag 16, people have a higher comfort level when wearing the elastic band 13.

[0034] In this embodiment, a holding groove 3 is formed in the front surface of the holding handle 2, and an anti-slip cloth 4 is adhesively bonded to the surface of the holding groove 3.

[0035] In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0036] In practical applications, the elastic strap 13 is tied to the arm through the magic tape 15. Due to the arrangement of the ventilation holes 14 and the water bag 16, the comfort level of people wearing it is relatively high. When using the spray gun, if it accidentally falls off, due to the arrangement of the elastic cord 12, the spray gun will not fall to the ground, thus preventing damage to the spray gun. Combined with the anti-slip cloth 4 in the holding groove 3, the friction force when people use the spray gun is increased, which can better prevent the situation of the spray gun falling when people use it. When using the spray gun, the part of the connecting pipe 5 that drags on the ground is placed into the limiting port of the connecting block 1001. The arc-shaped fixing plate 1003 clamps and fixes the connecting pipe 5 under the contraction deformation of the micro reset spring 1002. The anti-slip pad increases the contact friction force between the arc-shaped fixing plate 1003 and the connecting pipe 5, thereby improving the clamping stability of the wire harness assembly 10 on the connecting pipe 5. The guide block 9 can move and adjust the position of the wire harness assembly 10 under the action of the micro motor 7 driving the lead screw 8, with stronger applicability.

[0037] In summary, by means of the above technical solutions of the present invention, through the arranged wire harness assembly 10, the connecting pipe 5 can be limited and clamped to avoid abrasion caused by dragging on the ground during use. Moreover, according to the up and down height when people use the spray gun, the guide block 9 can move and adjust under the action of the micro motor 7 driving the lead screw 8, with relatively strong applicability. The arrangement of the elastic strap 13 can be tied to people's arms through the magic tape 15. When using the spray gun, if it accidentally falls, due to the action of the elastic cord 12, the spray gun will not fall, thus preventing damage to the spray gun. Combined with the anti-slip cloth 4 in the holding groove 3, the friction force when people use the spray gun is increased, which can better prevent the situation of the spray gun falling when people use it.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
