This patent uses a detector, which includes a base, on which a detection mechanism and a motor are fixed. The detection mechanism includes a frame, in which a bearing body and a pressure detection component for tightening the bearing body longitudinally and transversely are provided. A vibration machine is provided below the frame, and the frame is vibrated by the vibration machine so that the vibration force is transmitted to the bearing body through the pressure detection component. When the utility model is in use, by providing a pressure detection component for tightening the bearing body longitudinally and transversely in the frame, the pressure detection component is used to perform pressure detection on the bearing body, thereby early detection of problems caused by stress affecting the bearing body. By providing a vibration machine under the frame, the frame is vibrated by the vibration machine so that the vibration force is transmitted to the bearing body through the pressure detection component, thereby simulating real field conditions and early detection of problems caused by vibration affecting the bearing body.
