Through this setting, the limiting block 7132 can be moved out of the clamping block 72 to fix the clamping block 72.

[0028] The working principle is as follows:

[0029] First, before use, bring the workpiece to be coated to the side of the placement rack and wait for fixing.

[0030] Second, during use, adjust the position of the fixed bracket 4 according to the size of the workpiece. Rotate the first handle 64, which drives the first round rod 63 to rotate. When the first round rod 63 rotates, it drives the gear 62 to rotate. When the gear 62 rotates, it drives the fixed block 61 to move, so that the fixed block 61 moves out of the fixing hole 5, and then the position of the fixed bracket 4 can be moved. Subsequently, rotate the second handle 64 in the reverse direction to move the fixed block 61 into the fixing hole 5 to complete the fixation;

[0031] Third, then adjust the distance between the support blocks 71. Pull down the second handle 712, which drives the movable rod 78 to move, so that the movable rod 78 moves out of the limiting rod 711. Subsequently, rotate the second handle 712. When the second handle 712 rotates, it drives the movable rod 78 to rotate. When the movable rod 78 rotates, it drives the second round rod 74 to rotate through the fixed rod 79. When the second round rod 74 rotates, it drives the connecting sleeve 75 to rotate. When the connecting sleeve 75 rotates, it drives the connecting belt 76 to rotate. When the connecting belt 76 rotates, it drives the movable block 77 to move;

[0032] Fourth, when the movable block 77 moves, it drives the limiting block 7132 to move through the connecting rod 7131, so that the limiting block 7132 squeezes the spring 7135 along the optical rod 7133, and the limiting block 7132 cancels the limiting effect on the clamping block 72. Press the second handle 712 to fix the movable rod 78 by the limiting rod 711. Subsequently, pull the support block 71 to drive the clamping block 72 out of the clamping groove 73, insert the clamping block 72 into a new clamping groove 73. Then pull the second handle 712, and then rotate the second handle 712 in the reverse direction, so that the connecting belt 76 no longer pulls the movable block 77. After the spring 7135 loses the acting force, it releases the elastic potential energy to push the limiting block 7132 to move, so that the limiting block 7132 moves out of the clamping block 72, and fixes the clamping block 72 again. Finally, the workpiece can be fixed to the support block 71 and sent into the coating machine.
