The automobile rearview mirror is used to present the images of the rear, side and bottom of the vehicle, helping the driver understand the situation around the vehicle and expanding the driver's field of vision. The automobile rearview mirror is a very important part of the vehicle, and its quality, stability and reliability are related to driving safety. Therefore, before mass production and listing of the automobile rearview mirror, it is necessary to conduct a lens pulling force test. Passing the test indicates that the quality of the lens meets the standard. The pulling force of the rearview mirror lens refers to the force required to pull the rearview mirror lens from its installation position. The magnitude of this force is usually an important technical index, which reflects the firmness and reliability of the lens installation. In the automotive industry, there are usually certain standards and requirements for the pulling force of the rearview mirror lens to ensure that the lens will not fall off easily during normal use, thus guaranteeing driving safety and the normal functions of the vehicle.
