On the basis, the driver drives the first support 11 and the second support 12 to synchronously slide to approach or separate from each other, so that the first rotating clamp 21 and the second rotating clamp 22 are synchronously clamped, and the problem that the detection efficiency is influenced by poor flexibility and applicability of the traditional detection device is overcome to a certain extent.

The first support 11 and the second support 12 may be connected to the frame 10 by a guiding structure, such as a guiding rail or a guiding rod, so that the first support 11 and the second support 12 are slidably arranged along the extending direction of the guiding structure. For example, as shown in fig. 1, the frame 10 preferably has a pair of guide rails 15, and the first mount 11 and the second mount 12 are each slidably mounted to the frame 10 by the pair of guide rails 15. The sliding range of the first support 11 and the second support 12 on the frame 10 along the guide rail 15 can be limited by the stroke length of the guide rail 15, and preferably, a limiting structure is further provided on the frame 10 for limiting the sliding range of the first support 11 and the second support 12. The limiting structure may be a limiting mechanism such as a limiting stopper or a damper, and preferably, at least one limiting structure is respectively arranged on both sides of each support along the extending direction of the guide rail 15, so as to respectively limit the maximum distance and the minimum distance of the first support 11 and the second support 12 in the extending direction of the guide rail 15. The limit structure can also have a plurality of mounting positions on the frame 10, and the mounting position of the limit structure is adjusted, so that the range of the maximum distance and the minimum distance is changed, and the rotation detection device can be suitable for objects to be detected with various sizes.

According to the actual working condition environment, the rotation of the object to be detected can be realized by manually operating the first rotating clamp 21 and the second rotating clamp 22 to rotate in a clamping state, and the automatic rotation of the first rotating clamp 21 and the second rotating clamp 22 can also be realized by a rotation driving mechanism.
