Here, the rotation axis of the first rolling element 51 coincides with the width direction of the jig, and the rotation axis of the second rolling element 52 and the rotation axis of the first rolling element 51 are arranged in parallel to each other. In this way, the above arrangement ensures that the direction of movement of the first and second pulling

segments

531, 532 is along the length of the clamp, thereby causing the first and

second clamping assemblies

41, 42 to move towards or away from each other along the length of the clamp. Meanwhile, the above arrangement improves the transmission reliability of the transmission assembly 50.
