Meanwhile, the installation block 323 drives the installation plate 331, the chute plate 332, the connecting rod 333, the adjusting block 334 and the arc-shaped support plate 322 to synchronously move, and because the inclination angle of the connecting line changes at this time, the arc-shaped support plate 322 is not attached to the connecting line at this time, in order to ensure that the arc-shaped support plate 322 always keeps the attaching state with the connecting line, the adjusting block 334 can slide along the installation plate 331, the adjusting block 334 drives the pin shaft to synchronously move along the chute plate 332, the pin shaft moves and simultaneously drives the connecting rod 333 to synchronously rotate around the hinging points at two ends of the pin shaft, the connecting rod 333 drives the arc-shaped support plate 322 to synchronously rotate around the hinging points between the pin shaft and the installation plate 331 until the arc-shaped support plate 322 is attached to the connecting line again, and then the adjusting block 334 is fixed through the cooperation between the inserting rod 336 and the inserting hole 335, so as to push, the inclination angles of different arc-shaped support plates 322 are adjusted one by one and kept consistent.
In the subsequent detection process, the elastic telescopic rods 326 can be taken out from the left and right adjacent threaded rods 325 in the same mode so as to ensure that the different threaded rods 325 are not interfered with each other, the plurality of threaded rods 325 are connected into a whole through the elastic telescopic rods 326, the time required for adjusting the inclination angles of the connecting wires one by one is reduced, the adjustment speed is improved, different connecting wires can be adjusted to the same inclination angle, different arc-shaped supporting plates 322 can be adjusted to the same horizontal position, the consistency between the different connecting wires is improved, and the fact that the different connecting wires can always carry out torsion detection in the same state is ensured.
