Among many flat-panel displays, LCDs have many superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. LCDs have been widely used in various electronic products such as computer monitors, televisions, mobile phones, and tablet computers. Each LCD monitor needs to undergo various performance tests before leaving the factory, such as image testing to detect whether there are bad pixels, bright spots, dark spots, etc. on the LCD screen, and viewing angle testing to detect the display effects of the LCD monitor at different viewing angles, including color changes, brightness changes, etc.

[0003] Since LCD monitors that have not been completed are generally not installed with display base brackets, most of the current LCD monitors need to be manually supported by staff when being tested. The size and weight of the monitors are generally large, and long-term support will increase the workload of the staff. It is also easy for the LCD monitor to collapse due to operational errors of the staff, causing damage to the LCD monitor. When testing the LCD monitor, the LCD monitor needs to be constantly swung to perform tests on different items. Manually supporting the LCD monitor is very inconvenient and affects the efficiency of the test. Therefore, it is necessary to design a detection auxiliary device for LCD monitors that has good stability and is easy to operate to solve the above problems. Utility Model Content

The drop of the first sliding plate 4 will pull the two first tension springs 3, so that the two first tension springs 3 can be stretched. When the first sliding plate 4 drops, it will drive the support plate 5 to drop a certain distance. When the support plate 5 drops, the tensile force on the second tension spring 10 will gradually decrease, and the second tension spring 10 will shrink. The second tension spring 10 will drive the clamping plate 9 to move close to the LCD display until it contacts the LCD display, so that the LCD display can be clamped.
