When the position of the screw is adjusted, the end of the screw needs to be clamped by the clamping block 404, so that the motor 402 drives the screw to rotate, and the position of the screw is adjusted. In order to realize that the clamping blocks 404 can be clamped relatively when rotating synchronously along with the motor 402, one end of the rotating shaft 403 facing the clamping blocks 404 is divided into two parts by an axial through groove 407, the two clamping blocks 404 are respectively arranged at the end parts of the two parts, a cavity 408 with the height larger than that of the through groove 407 is arranged at the inner end of the through groove 407, and the two clamping blocks 404 can move oppositely to compress the through groove 407.

The screw rod extends into the notch 409, and the two clamping blocks 404 move relatively to clamp the screw rod and rotate synchronously along with the rotating shaft.

In order to drive the two clamping blocks 404 to clamp or unclamp, a pair of clamping plates 411 arranged on two sides of the clamping blocks 404 is mounted at the position of the rotating shaft 403 where the cavity 408 is arranged through a linear bearing 410, and the clamping plates 411 drive the two clamping blocks 404 to clamp or unclamp through axial movement on the rotating shaft 403.

In order to clamp and release the clamping blocks 404 through the clamping plates 411, guide posts 412 are arranged on two sides of each clamping block 404, a pair of guide grooves 413 with opposite inclined inner ends are respectively arranged on each clamping plate 411, and the two guide posts 412 on the same side of the two clamping blocks 404 can move in the guide grooves 413 of the same clamping plate 411.

When splint 411 removed towards clamp splice 404, two guide posts 412 of homonymy removed to the guide way 413 inner end, and the slope setting of guide way 413 then can drive two clamp splices 404 and remove in opposite directions to press from both sides the screw rod tightly, when splint 411 reverse movement, guide post 412 withdraws from the guide way 413, and clamp splice 404 then can reset and open, can loosen the screw rod.

In order to realize the axial movement of the clamping plate 411 on the rotating shaft 403, the rotating shaft 403 passes through a set of telescopic members and is in transmission connection with the motor 402 through a coupler 414, and the telescopic members can drive the clamping plate 411 to axially move on the rotating shaft 403.

In order to move the clamp plate 411 through the telescopic member, the telescopic member includes a front end plate 415 and a rear end plate 416 which are oppositely arranged, and two telescopic cylinders 417 which are arranged between the front end plate 415 and the rear end plate 416, wherein the front end plate 415 is connected with the linear bearing 410 through a plane bearing 418.

Laser sensor 406 may be selected from, but is not limited to, laser sensor 406 of the type IEC 60825-1.

The torque sensor 401 may be selected from, but is not limited to, a torque sensor 401 having a model number DYN-201.

In the position measurement of the screw, the distance range between the screw and the laser sensor 406 may be set directly on the touch panel 425, or a standard range setting may be performed using a standard member, and the same acceptable torque range may be set by using both methods. The dimming support to be detected is placed on the mounting seat 405, then the telescopic air cylinder 417 is started, the screw rod is clamped by the clamping block 404, the motor 402 is started to rotate the screw rod, the laser sensor 406 detects the distance between the screw rod and the laser sensor in real time, and when the set range is reached, the motor 402 stops rotating. While the motor 402 rotates, the torsion sensor 401 can detect the torque of the screw rod at the same time, and can pick out the torque in time if the torque is not within a qualified range, so that subsequent use is prevented from being influenced.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention.
