[0037] Working principle: when relevant personnel need to perform hot stamping operation on the heat dissipation grille, first place the heat dissipation grille on multiple groups of wedge blocks 605. When the heat dissipation grille contacts the inclined surface of the wedge block 605, the wedge block 605 moves and the length of the connecting spring 610 changes. The heat dissipation grille is placed in the middle position due to the elasticity of the connecting spring 610, thereby completing the positioning operation. After positioning, the corresponding fixing operation is performed to fix the heat dissipation grille. The operation of fixing the heat dissipation grille is a prior art and will not be explained in detail here. After fixing, the electric telescopic rod 5 is started to move downward to complete the hot stamping operation, thereby avoiding manual observation and adjustment to achieve a quick positioning effect. The operation is simple and convenient, and the positions of multiple groups of moving seats 604 can be adjusted. The adjustment operation is to rotate the threaded rod 602 so that the threaded rod 602 drives the corresponding moving seat 604 to move, and then the moving seat 604 drives the connecting rods 603 on both sides to open, thereby making the moving seats 604 on both sides move outward, and at this time, the moving seat 604 at the rear end will move toward the middle, thereby being able to adapt to the positioning of heat dissipation grilles of different models. The operation is simple and convenient.

[0038] When the curvature of both sides of the heat dissipation grille needs to be adjusted, first move the corresponding plug-in column 704 upward, then rotate the moving block 607, and then rotate the wedge block 605 to adapt to some heat dissipation grilles with curvature. At the same time, when the moving block 607 rotates, it can drive the pointer 701 to rotate, and then the pointer 701 corresponds to the scale on the positioning column 608 to determine the rotation angle, and then the other set of moving blocks 607 can be rotated to the same angle.
