[0010] The C-profile front columns are installed on the left and right sides of the front of the cabinet, and the exteriors of the deep lining and the knife switch mechanism beam are both provided with self-tapping locking screws.

[0011] The knife switch mechanism beam and the C-profile front column are both provided with corresponding holes on their exteriors, and the knife switch mechanism beam is provided with an operating hole on its exteriors.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:
