An arc-shaped locking mechanism disposed on the right side of the frame includes a rotating block between the front side plate and rear enclosure plate; a knob outside the front end of the front side plate and fixedly connected to the rotating block; and multiple differently inclined plates on the outer ring of the rotating block. The oblique boss of one frame is operative to abut against different inclined plates of an adjacent frame, respectively.
