[0023] In use: Place the armored door horizontally between two L-shaped clamps 6. Drive the first electric push rod 7 to move the L-shaped clamps 6 to contact the armored door. The two L-shaped clamps 6 clamp and fix the armored door from both sides. The armored door is suspended and fixed in the groove 2. Turn on the first motor 10 to drive the first lead screw 11 to rotate.
