Two adjacent connecting blocks 84 will move in opposite directions. The connecting block 84 drives the slide 7 to move horizontally. The slide 7 drives the clamping block 10 to move horizontally and contact the workpiece to clamp and position it. This allows the vehicle frame to be positioned both laterally and longitudinally, resulting in better positioning, improved stability, and improved testing results.

[0025] During the horizontal movement of clamping block 10, clamping block 10 will first contact the side of the frame. Then clamping block 10 stops moving while slide block 7 continues to move. Slide block 7 will drive slide rod 95 and slider 92 to move. Slide block 92 will drive ball 93 to roll along groove 94. Slide block 92 will squeeze spring 91. Under the elastic action of spring 91, it will give clamping block 10 a reaction force, so that clamping block 10 can clamp and position the workpiece. This allows clamping block 10 to simultaneously position workpieces of different sizes, resulting in better positioning effect.
