[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This rapid device for detecting residual stress in automotive headlight covers allows for easy movement over short distances. Operators can hold the handle and pry the main body of the device backward, causing the wheels to contact the ground. The handle and wheels then work together to move the device. For lifting to higher ground, the hoisting rope and lifting rings can be connected, allowing the entire device to be hoisted. This process can be performed by a single person. When testing for residual stress in the headlight cover, the cover is placed on a lighting platform. A camera captures the image, which is then transmitted to a display screen for initial inspection. If cracks or breaks are found, further testing is unnecessary. If no damage is found, the headlight cover is placed on an ultrasonic receiver for non-destructive testing via an ultrasonic transmitter. Attached Figure Description
