Automobile safety belt lock catch quality detection device

The invention discloses an automobile safety belt lock catch quality detection device. The device comprises a hydraulic cylinder, wherein the hydraulic cylinder is installed on a case, a display screen is installed on the outer portion of the case, a control chip is arranged at one side of the display screen, and the hydraulic cylinder is connected with a connecting base through connecting shafts.According to the device, the hydraulic cylinder, the display screen, a first laser range finder and second laser range finders are controlled through the control chip; when the hydraulic cylinder enables a press-down plate to press down a lock catch, the first laser range finder performs ranging on the compression length of a spring, so that the magnitude of pressure borne by the lock catch is obtained; an indicating strip is attached to the surface of the lock catch, and the second laser range finders measure the deformation of the lock catch according to the position change of the indicating strip; and the control
