The rectangular positioning block 316 plays a positioning role on the paralleling guide plate 302, ensuring the position accuracy of the paralleling guide plate 302 on the base 301.

[0032] In some embodiments, see Figures 1 to 4 , the support seat 304 is fixedly connected to the base 301 by a cable tie 317. In this embodiment, a through hole for the cable tie 317 to pass through is provided on the base 301. One cable tie 317 passes through the through holes on the two bases 301 at the same time, thereby fixing the two bases 301. In order to make the connection between the base 301 and the support seat 304 more secure, two cable ties 317 are installed between the support seat 304 and the base 301, and the two cable ties 317 are symmetrically arranged relative to the base 301. The top and bottom surfaces of the support seat 304 are provided with positioning grooves 318 that match the cable tie 317. The positioning grooves 318 limit the cable tie 317, thereby effectively preventing the cable tie 317 from being displaced relative to the support seat 304, thereby ensuring the relative stability between the support seat 304 and the base 301.
