[0024] As Figures 1 - 3 shown, a plurality of limiting rods 16 are fixedly connected to the outer surfaces of the two moving blocks two 11, limiting blocks 17 are fixedly connected to the outer surfaces of the plurality of limiting rods 16, springs 18 are movably sleeved on the outer surfaces of the plurality of limiting rods 16, the plurality of limiting rods 16 are evenly divided into four groups, limiting plates 19 are movably sleeved on the outer surfaces of the four groups of limiting rods 16, realizing the fixation of the product to be detected by the two limiting plates 19, avoiding the installation difficulty caused by the large size of the laminated glass, improving the user experience, and having a simple structure and convenient operation, which is convenient for use.

[0025] As Figures 1 - 3 shown, the motor 2 is fixedly connected to the top of the working frame 1, a stamping mechanism 20 is arranged on the top of the working frame 1, and the motor 2 can provide power for the rotating shaft 3 to make the rotating shaft 3 rotate.

[0026] As Figures 1 - 3 shown, sliding grooves one 15 are formed on both sides of the working frame 1 close to the two sliding rods one 7, the two sliding rods one 7 are movably embedded in the inner surfaces of the two sliding grooves one 15, and the sliding grooves one 15 can limit the sliding rods one 7 to avoid derailment of the sliding rods one 7 and affect the use of the equipment.

[0029] Working principle: This equipment is a closed laminated glass impact test stand. When in use, manually pry open the two limit plates 19 so that the two limit plates 19 move in opposite directions on the multiple limit rods 16 and stretch the two springs 18. Because the spring 18 is fixedly connected to the moving block 11, the two springs 18 will obtain elastic potential energy. The limit block 17 can prevent the limit plate 19 from excessive movement and detach from the limit rod 16. Then place the product to be tested on the moving block 11 close to the middle position of the two limit plates 19, and then release the two limit plates 19. The two springs 18 release the elastic potential energy, so that the two limit plates 19 move to the initial position, and then start the motor 2 on the working frame 1. The motor 2 is equipped with a stepper and can realize forward and reverse rotation. The motor 2 drives one of the rotating shafts 3 to rotate through the output shaft. , one of the rotating shafts 3 drives the synchronous belt 5 to rotate through the synchronous wheel 4. Because the two clamping blocks 6 are clamped on the two synchronous belts 5, the synchronous belt 5 will cause the two clamping blocks 6 to move in opposite directions when it rotates. The two clamping blocks 6 drive the two slide bars 7 to move in opposite directions on the inner surfaces of the two slide grooves 15. The two slide bars 7 drive the two moving blocks 8 to move in opposite directions. The two moving blocks 8 drive the two moving blocks 11 to move in opposite directions through multiple slide bars 2 10. The two moving blocks 2 11 drive the two pulleys 13 to move in opposite directions on the inner surfaces of the two special-shaped grooves 14 through two fixed rods 12. Because the contour of the special-shaped groove 14 is tortuous, the two moving blocks 2 11 will move to both sides. The slide bar 2 10 and the slide groove 2 9 can limit the moving trajectory of the moving block 2 11.
