[0029] The utility model uses an angle ruler 1 to split the space angle into a plane angle and a longitudinal angle, and achieves the accuracy of the space bend assembly by controlling the plane angle.
[0030] The above-mentioned installation means detachable fixation, which can be bolt connection, snap connection, or bonding. Those skilled in the art can select any fixing method according to actual needs.
