[0031] The second control component drives multiple regulating components, and the regulating components control the engaging components to adjust the limit state of the winding wheel 7, so that the multiple winding wheels 7 are in an idling state, so that the multiple gravity balls 9 automatically fall by gravity, and the impact test is performed on the tested material, so as to achieve a more comprehensive multi-point impact test on the tested material and improve the accuracy of the impact test;

[0032] When the winding wheel 7 is in an idling state, the slide plate 11 is pulled simultaneously to slide along the slide rod 10 to a distance adapted to the height of the gravity ball 9. After the gravity ball 9 completes the impact, the second control assembly is reset, so that the multiple winding wheels 7 are in a locked state connected to the first transmission assembly. Therefore, when the slide plate 11 is reset, the first control assembly drives the second transmission assembly, and the second transmission assembly drives the multiple first transmission assemblies, so that the multiple winding wheels 7 rotate to wind the rope, thereby causing the multiple gravity balls 9 to reset synchronously.

[0033] The first screw group 3 is used to adjust the height of the gravity ball 9 , and the second screw group 5 is used to adjust the plane position of the gravity ball 9 .

[0038] By the movement of the slide plate 11, the drive ring 23 is driven to move synchronously by the slide plate 11, so that the toggle block inserted into the spiral groove 22 by the drive ring 23 cooperates with the spiral groove 22, so that the connecting rod 21 rotates, and the connecting rod 21 drives the second worm 20 to rotate, and the second worm 20 drives the multiple second worm wheels 19 to rotate, so that the multiple first worm gears 18 rotate, and then the multiple first worm wheels 17 rotate, so that the first worm wheel 17 drives the sleeve 15 to rotate.

[0039] To further optimize the solution, the regulating component includes a ring 24, a pull rope 25, a first spring 26 and a guide wheel 27. The ring 24 is fixedly sleeved on the rhombus column 14.

On the contrary, the second connecting plate 30 is released, and the first connecting plate 29 can be automatically reset by the first spring 26, so that the first clutch block 12 and the second clutch block 13 are pressed against each other to lock the winding wheel 7.

[0041] A further optimized solution is that the second control component includes a pressure plate 33, which is located on multiple second connecting plates 30, and the pressure plate 33 is against the multiple second connecting plates 30.

[0045] A further optimized solution is that a pair of support frames 38 are fixedly connected to the base 1, a limit plate 39 is arranged between the support frame 38 and the base 1, and a plurality of cylinders 40 are fixedly installed between the limit plate 39 and the support frame 38. The limit plate 39 is pushed by the cylinder 40 to clamp the material to be tested.

[0046] It should be noted that for the convenience of operation, during operation, the fourth connecting plate 34 can be held and pressed down. At this time, the first clutch block 12 and the second clutch block 13 are separated, so that multiple gravity balls 9 automatically fall down and impact the material to be tested. At this time, the downward action of the fourth connecting plate 34 is maintained, and then the slide plate 11 is pulled, so that the connecting rod 21 drives the multiple second clutch blocks 13 to rotate until the slide plate 11 is in a suitable position, and then the slide plate 11 and the fourth connecting plate 34 are released, and the second spring 36 pushes the fourth connecting plate 34 to automatically reset. At the same time, the first spring 26 pushes the first connecting plate 29 to automatically reset, and the first clutch block 12 and the second clutch block 13 are against each other. At the same time, the third spring 37 pulls the slide plate 11 to automatically reset, so that the multiple winding wheels 7 rotate, so that the multiple gravity balls 9 are reset synchronously.
