[0019] Working principle: First, the staff fits the installation plate 1 with the outer side of the I-beam 2, and passes several fixing tubes 6 through the through-hole. Before passing through the through-hole, the staff can first press the two clamping plates 36 to flip them to each other and enter the inner cavity of the rectangular opening, and at the same time move the sphere 38 to the front side to facilitate the fixing tube 6 to pass through the through-hole. After passing through the through-hole, due to the spring force of the fixing spring 37, the sleeve plate 35 can be driven to move to the front side, and the corresponding side of the two clamping plates 36 is in contact with the outer side of the sphere 38, so that the two clamping plates 36 are flipped back and fit with the inner wall of the I-beam 2. Then the staff rotates the bolt 40 to move it to the rear side and fit with the outer wall of the I-beam 2, thereby completing the purpose of fixing the load-bearing steel 3. If a natural disaster or human factor causes the load-bearing steel 3 to be deformed, the load-bearing steel 3 may tilt, causing the horizontal ball 13 to roll and contact the trigger block 15. When the trigger block 15 on the front side is hit, the active push block 10 can be driven to move to the front side through the connecting rod 9 and contact the reciprocating push block 16, thereby driving the reciprocating push block 16 to move away from the load-bearing steel 3. When the reciprocating push block 16 moves, the translation plate 17 can be driven to move away from the load-bearing steel 3. When the translation plate 17 moves, the two cranks 23 can be used to drive the two scissors 22 to flip in opposite directions, thereby cutting the steel wire 34. When the trigger block 15 on the rear side is hit, the movable push block 11 can be driven to move to the rear side through the moving rod 12, contact the reciprocating push block 16, and repeat the above movement process. When the steel wire 34 is cut, the rack 25 moves downward under the action of gravity and drives the gear 29 to rotate. When the gear 29 rotates, it can drive the two screw rods 30 to rotate. Since the outer threads of the two screw rods 30 are arranged in opposite directions, the two threaded plates 27 can move in opposite directions. The threaded plates 27 are fitted with the guide plates 26 through the slide plates 31 to limit the moving trajectory. When the two threaded plates 27 move, they can drive the adjacent clamping plates 7 to move. The two clamping plates 7 can fix and clamp the I-beam 2 to provide secondary fixation for the load-bearing steel 3.
