However, in actual use, we found that the clamping objects of these limiting mechanisms are usually fixed, and their adaptability to automobile instrument cover frames of different specifications is poor. Moreover, after each clamping, the automobile instrument cover frame is generally put into the receiving box from the top of the receiving box, which may cause damage to the automobile instrument cover frame. Therefore, how to solve this problem is what we need to consider. Utility Model Content
