The second sensor 159 is aligned with the guide 129 at the lower end of the connecting shaft 128, and when the connecting shaft 128 rotates, the second sensor 159 is misaligned with the guide 129, and the second sensor 159 sends a signal indicating that the detecting head 127 is not aligned with the nut on the bolt 04 to be detected. During the detection, if the second sensor 159 is offset from the guide 129, it indicates that the detection head 127 rotates with the bolt 04 to be detected, that is, it indicates that the nut on the bolt 04 to be detected is loose, and maintenance and inspection are required.

The upper end of the detecting head 127 is provided with a projection 1271 aligned with the first sensor 158, and in the case where the second sensor 159 is aligned with the guide 129, if the projection 1271 is misaligned with the first sensor 158, it means that the detecting head 127 has moved relatively along the connecting rotation shaft 128, that is, the detecting head 127 is pushed up by the bolt 04 to be detected. At this point, the position of the torque sensing assembly 12 needs to be adjusted again so that the sensing head 127 is aligned with the bolt 04 to be sensed. When the second sensor 159 is aligned with the guide 129, the first sensor 158 is also aligned with the projection 1271, which indicates that the head 127 is properly aligned with the bolt 04 to be tested. At this time, the detection head 127 can be accurately sleeved on the bolt 04 to be detected.

in order to judge the relative position between the detection head and the bolt to be detected more accurately, the adjusting time of the torque detection assembly is shortened, the operation process is visual, and the operator can operate the position adjustment between the detection head and the bolt to be detected more intuitively.
