[0021] In this embodiment, Figure 3 and Figure 4As shown, the bottom ends of the connecting rod 307 are connected by a connecting shaft, and the connecting shaft passes through the mounting plate 302 and is rotationally connected to the mounting plate 302, the mounting plate 302 and the sub-gear 304 are rotationally connected by the connecting shaft, and the sub-gear 304 and the main gear 308 are fixedly connected with an extension rod 305; this structure can drive the main gear 308 and the sub-gear 304 to move synchronously under the drive of the motor 303, and can simultaneously drive the two clamping jaws 306 to move with the two connecting rods 307, and the two clamping jaws 306 move in opposite directions, so as to clamp and fix the middle wire. This structure can clamp wires of different diameters, thereby improving the adaptability of the inspection equipment.

[0022] In this embodiment, Figure 3 and Figure 4 As shown, there are two clamping jaws 306, and the two clamping jaws 306 are symmetrically distributed about the center line of the mounting plate 302, and the inner sides of the two clamping jaws 306 are both arc-shaped structures; the arc-shaped clamping jaws 306 can better fit the surface of the wire when clamping the wire, making the clamping more stable.

The lifting column 1 without the support of the support sheet 402 will fall under the influence of gravity. Because the bottom surface of the lifting column 1 is flush with the zero scale of the scale line 408 in the initial state, the reserved degree of the wire can be obtained by observing the distance moved by the bottom surface of the lifting column 1. This structure does not require manual measurement, the operation process is simple and the error is small.
