[0002] Tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. Ability to enhance the glass's own wind pressure resistance, cold and heat resistance, impact resistance, etc. When testing tempered glass, the impact resistance test of tempered glass is one of the important items. When testing, the sample is clamped on the sample holder Draw a circle with the geometric center of the sample as the center and a radius of 25 mm, adjust the impact height of the steel ball to the height specified in the test standard, and loosen the steel ball so that the steel ball falls freely on the geometric center, and the tempered glass is tempered. However, when the current experimental device is in use, it is troublesome to place it. It is necessary to lift the upper frame down, place the sample, and then place the upper frame on the sample. During the experiment, when the glass breaks , there is the problem that it is not convenient to collect broken glass, and after the steel ball reaches the set position, it is easy to rotate, resulting in the landing point not being on the geometric center, there is a problem of large error, it is not convenient to use, and the steel ball When the height is adjusted, there is a problem that it is inconvenient to adjust
