[0002] A coupler is a hook at both ends of a train car or locomotive, which has the functions of connection, traction and buffering. A coupler is a vehicle component used to connect a locomotive and a vehicle or between vehicles, transmit traction and impact force, and keep a certain distance between vehicles. Before a train leaves the factory, the installation height of the coupler needs to be measured. The qualified height limit for coupler inspection is 880±10mm (according to the iron standard TB / T3044-2002TB / T3046-2002), that is, the height difference of couplers on the same vehicle shall not exceed 10mm. When the coupler height exceeds the allowable error range, the force-bearing area of ​​the hook tongue of the coupler connection will be reduced, thereby causing the natural separation of the coupler, resulting in a decoupling accident, endangering driving safety, and the consequences are unimaginable. It not only seriously threatens driving safety, but also causes serious losses to people's lives and property. At present, most of the measurements of coupler height are still carried out using measuring tools such as steel tape measures. Although this method is convenient, the measurement accuracy is not high enough.

[0003] The Chinese utility model patent with publication number CN219454906U discloses a locomotive coupler height measuring tool, including: a base, a mounting plate, a vertical pole and a vernier ruler, the mounting plate is slidably connected to the upper surface of the base, one end of the vertical pole is hinged to the upper surface of the mounting plate, the vernier ruler is connected to the vertical pole, the vernier ruler is a digital display vernier ruler, and the vernier ruler is used to measure the height of the locomotive coupler.

[0032] Working principle: When it is necessary to unfold, the two folding beams 8 are opened to separate the folding fixed magnet 1 6 and the corresponding folding fixed magnet 2 9. When the folding beam 8 swings and unfolds, the unfolding fixed magnet 2 11 and the corresponding unfolding fixed magnet 1 10 are adsorbed together.
