Referring to fig. 6, further, a first sliding chute 323 is disposed on the rotating hanging plate 320, a sliding block 324 is disposed in the first sliding chute 323, one end of the hook 322 is connected to the sliding block 324, and the sliding block 324 can drive the hook 322 to slide along the first sliding chute 323, so as to move the hook 322 to the position above the second limiting hole 304 of the member to be sprayed 301. The center of the rotating hanging scaffold 320 is provided with a mounting hole 321, a first sliding chute 323 extends from the mounting hole 321 to two ends along the same straight line, and two sliding blocks 324 are respectively loaded from the inlets of the first sliding chutes 323 at two sides of the mounting hole 321 and slide to the left and right sides of the first sliding chute 323; the first sliding groove 323 has a limiting wall at the left and right ends to prevent the sliding block 324 from coming off from the two ends.

Specifically, the slider 324 includes a sliding portion 325 and a connecting portion 326, the sliding portion 325 has a wedge-shaped cross section (which may be T-shaped or other types), the first sliding groove 323 has a matching wedge-shaped cross section, and the sliding portion 325 is prevented from falling off after being fitted into the first sliding groove 323; the connecting portion 326 is disposed on the sliding portion 325, a connecting hole 327 is formed in the connecting portion 326, one end of the hook 322 passes through the connecting hole 327, after the lower end of the spray-coated part 301 is fixed, the hanging plate 320 is rotated, the hook 322 is rotated to a position above the second limiting hole 304, and the other end of the hook passes through the second limiting hole 304, the rotating hanging plate 320 is adjusted, so that the hook 322 on the other side also passes through the corresponding second limiting hole 304.

In addition, the to-be-sprayed member 301 may be hung on the rotating hanging plate 320 through the hanging hook 322, and then the to-be-sprayed member 301 is rotated to be parallel to the positioning surface 315 on the rotating table 310, the lower end of the to-be-sprayed member 301 abuts against the positioning surface 315, and the lower end of the to-be-sprayed member 301 is fixed on the positioning surface 315 through the first limiting member 313.

Because the height of the piece 301 to be sprayed when vertically placed is much greater than the height of the positioning surface 315, before the second limiting member is connected, it is difficult to achieve firm limiting of the piece 301 to be sprayed only by the limiting column, and the piece 301 to be sprayed is easily tilted and difficult to keep vertical. Therefore, referring to fig. 7, in this embodiment, the rotating table 310 is further provided with a clamping member 330, the clamping member 330 is disposed opposite to the positioning surface 315, and after the lower end of the to-be-sprayed part 301 is connected to the first limiting member 313, the clamping member 330 is engaged with the positioning surface 315, specifically, the clamping member 330 presses the to-be-sprayed part 301 against the positioning surface 315, so as to clamp and fix the lower end of the to-be-sprayed part 301.

Further, referring to fig. 7, a spring 332 is connected to the clamping member 330, the other end of the spring 332 is fixedly connected to the rotating table 310, and the spring 332 can drive the clamping member 330 to move toward the positioning surface 315 to clamp the member 301 to be sprayed.

Further, the clamping member 330 can be fixed on the side of the to-be-sprayed member 301 far away from the positioning surface 315 through the fixing member 334, so as to leave a space for manual operation (limiting the lower end of the to-be-sprayed member 301), thereby avoiding interference. After the member 301 to be sprayed is connected to the first position-limiting member 313, the fixing member 334 is removed, the clamping member 330 is released from being fixed, and the spring 332 drives the clamping member 330 to move toward the positioning surface 315.
