[0054] In this embodiment, during actual measurement, the detection base 3 is directly inserted into the second storage slot 132 of the main frame, and then the socket head 63 of the wiring assembly 6 is inserted through the top plate 13 into the wiring socket 313 for connection and use. Testing and correction are required before use. The handle frame 311 is started to drive the magnetic detection group 4 to rotate. When the infrared receiver 22 receives the signal from the infrared transmitter 44, it stops rotating and sets the position as the initial position. The magnetic probe 43 on the magnetic detection group 4 is used for detection. The detection data is transmitted to the system through the wiring assembly 6, and then the magnetic detection group 4 is driven to rotate by the handle frame 311, and the next magnetic probe 43 is used for detection. The data after the detection of all magnetic probes 43 is averaged and displayed on the display as the final detection result. When the equipment needs to be repaired, the socket head 63 of the wiring assembly 6 is first removed from the positioning slot 133, and then the handle frame 311 can be held to remove the detection base 3 from the second storage slot 132, so as to facilitate the maintenance of the magnetic detection group 4 and the driving component 5 on the detection base 3.
