In addition, the tension of the cable between the two wire blocks will also affect the accuracy of its detection. In the comparative documents, the tension for fixing the cable is often determined by manual experience, that is, the accuracy of the tension is difficult to control.

The first motor 123 is fixed to the frame 110, and the output shaft of the first motor 123 and the double-threaded rod 121 are connected together through a gear transmission member 124. The arrangement of the double-threaded rod 121 and the guide rod 125 enables the two T-blocks 122 to move toward or oppositely. The spacing adjustment mechanism 120 is arranged to adjust the spacing between the two columns 130;

[0024] The upper end of the column 130 is fixed to the lower surface of the curved plate 140, the first cylinder 150 is fixed to the outer wall of the curved plate 140, the piston rod end of the first cylinder 150 is fixed to the outer wall of the clamping plate 160, and further includes an anti-slip pad 170, which is fixed to the outer wall of the clamping plate 160.

Installed between the two brackets 180, the dustproof mechanism 192 and the grinding mechanism 193 are both installed on the frame 110. The dustproof mechanism 192 is set to reduce dust in the air.
