[0002] Solar films, also known as heat insulation films, in modern solar film production technology, metal layers such as aluminum, gold, copper, silver, etc. are often made into multi-layer dense high heat insulation metal film layers through vacuum spraying or magnetron sputtering technology. In applications, it is often adhered to smooth surfaces such as car window glasses for light and heat insulation. When the glass suddenly bursts or is impacted or struck by external forces, if the impact resistance of the solar film is poor, the glass is likely to suddenly burst, causing injury accidents. Therefore, it is necessary to detect the impact resistance of the produced solar films to ensure their safety performance, reduce the splashing of glass fragments, and protect people from harm.

[0030] In a preferred embodiment, the first crossbar 2, the second crossbar 4, the third crossbar 5, and the fourth crossbar 8 are symmetrically arranged with respect to the vertical rod 3. This helps to achieve force balance and enhance the stability of the linkage mechanism.

[0031] In a preferred embodiment, the structure of the fixing device is as follows: on both sides of the fixing ring 9, cylinders 10 are symmetrically provided. The upper surface of the cylinder body is flush with the upper surface of the fixing ring 9. The output shaft of the cylinder 10 is connected to both sides of the pressing ring 11.
