There are two fixing plates 101b symmetrically arranged along the left and right sides of the fixing base 101a, which can clamp the grid plate on the stator to fix the clamping and fixing assembly 101. The clamping and fixing assembly 101 further includes an adjusting rod 101c, an adjusting button 101d, a clamping block 101e, and a clamping block spring 101f disposed inside the fixing base 101a. One end of the adjusting rod 101c is rotatably connected to the fixing plate 101b, and the other end is engaged with the adjusting button 101d. There are two clamping blocks 101e symmetrically arranged along the left and right sides of the fixing base 101a and engaged with the adjusting button 101d.

[0035] Furthermore, the lower end of the fixing base 101a is a fixing plate sliding groove 101a-1, and the fixing plate 101b is engaged therewith and can move relatively closer to or away from each other along the fixing plate sliding groove 101a-1, so as to clamp grid plates of different widths. Connecting grooves 101a-2 are vertically arranged on both sides of the fixing base 101a and are engaged with the arc adjusting assembly 201.

[0047] Furthermore, the arc measuring assembly 202 includes a placement housing 202a, a second induction block 202b disposed at the front end of the placement housing 202a, and a second induction spring 202c connected thereto. The placement housing 202a is respectively fixedly disposed on the end telescopic ring 201a, the first telescopic ring 201b, and the second telescopic ring 201c. At the same time, sensors can be placed in the measuring groove 101a-5 and the placement housing 202a to detect and record the positions of the first induction block 102a and the second induction block 202b.
