step four, adjusting the frame height: when need to set a height and place protecting sheathing (1), pull down spiral shaft (7), break away from behind blind hole (15) at guide pillar (14), take out protecting sheathing (1) with front shroud (6) and back shroud (5) cooperation tooth board (4) together, then change front shroud (6) and back shroud (5) position, insert two tooth boards (4) in protecting frame (3) again, remove to setting for after the distance, upwards promote spiral shaft (7), first magnetic force piece (11) and second magnetic force piece (12) attract each other, and guide pillar (14) insert in blind hole (15), accomplish the fixing of setting for distance back front shroud (6) and back shroud (5) position, realize the height of protecting sheathing (1) and place.
