[0003] In the existing technology, the over-limit and overload vehicle weighing detector mainly includes a weighing plate main body and lap plates installed on both sides of it. After the weighing plate and the lap plates are installed, they are placed on a plane at a certain distance. The car tires roll over them, and the sensors inside them transmit the weight of the cars passing over them.

[0004] At present, due to the portability of overloaded and overweight vehicle weighing detectors, road maintenance personnel will carry them to various sections of the road to conduct weight detection on vehicles passing through the section. After taking out the device and placing it on the road surface, the distance between the weighing plates needs to be controlled by moving or pushing. The moving method will increase the labor loss of the staff, and the friction generated during the pushing process will increase the wear and tear of the device.

[0005] Therefore, in order to solve the above problems, a portable inspection tool for automobiles is proposed. Utility Model Content
