[0002] In recent years, the operation quality and passenger safety of elevators have become the focus of people's daily attention. Therefore, strengthening the inspection of the manufacturing quality of elevator parts and conducting relevant inspections and verifications has become one of the important means to improve the quality of elevators and prevent and reduce accidents. The parts made of plate in elevators (such as elevator shaft walls, floor doors, car doors, car walls, etc.) will produce a certain degree of concave deformation under the action of external forces. The deformation value of these plate-shaped parts under the action of specified external forces is an important indicator to measure the strength performance of elevator plate-shaped parts.

[0003] Elevator strength testing involves strength testing of floor doors, hoistways, toe boards, car tops, car walls and other parts. The existing instrument structure can only cover one part and cannot cover all parts involved in the elevator strength test. During the testing process, multiple measuring tools need to be prepared for measurement, which is cumbersome and time-consuming. Summary of the invention
