After the clamping device 30 stretches into the hole of the workpiece to be painted and the box-shaped space communicated with the hole, an operator drives all pistons 21 to push towards the pneumatic rods 32 through the integral adjusting device, and at the moment, all the pneumatic rods 32 stretch until the supporting bracket 31 is tightly attached to the inner wall of the box-shaped space. The integral adjustment device is then screwed or otherwise secured. At this time, all the brackets 31 are not tightly fitted with the inner wall of the box-shaped space, so that independent adjusting devices capable of driving the single pistons 21 to independently act are also required to be respectively adjusted to drive the single pneumatic rods 32 to independently stretch and retract until each bracket 31 is tightly fitted with the inner wall of the box-shaped space, and the whole to-be-painted part is not swayed.
