The other end of the steel plate bending part falls on the top surface of the angle adjustment block (22). At the same time, place a component template (21) with the same thickness behind one end of the steel plate component (4). ② Unscrew the locking nut (24) so ​​that the telescopic screw (23) and the angle adjustment block (22) can move along the axis of the telescopic screw (23).
