The second floor slab 17 is equipped with a first auxiliary support steel pipe 4, a second auxiliary support steel pipe 5, and a main support steel pipe 6.
[0020] Please refer to Figures 2, 3, and 4. The limiting mechanism 14 includes an annular groove 141. The rotating block 13 has an annular groove 141 inside. A slider 142 is slidably connected inside the annular groove 141. A pull rod 143 is fixedly connected to the end of the slider 142 away from the annular groove 141. A handle 144 is fixedly connected to the end of the pull rod 143 away from the slider 142. A connecting seat 145 is fixedly connected inside the channel steel beam 11. The connecting seat 145 contacts the handle 144. The handle 144 is made of iron. By designing the handle 144 to be made of iron, the handle 144 becomes more durable. An elastic locking block 146 is engaged inside the connecting seat 145. The elastic locking block 146 is fixedly connected to the pull rod 143. By designing the elastic locking block 146, the pull rod 143 can be limited. A sliding block 149 is slidably connected inside the connecting seat 145. The internal sliding connection is connected by guide rods 147. There are two guide rods 147, which are symmetrically distributed inside the connecting seat 145. By designing the guide rods 147, the sliding block 149 can be guided.
[0021] Please refer to Figures 2, 3, and 4. A spring 148 is provided on the outer side of the guide rod 147. One end of the spring 148 is fixedly connected to the sliding block 149, and the other end of the spring 148 is fixedly connected to the connecting seat 145. By designing the spring 148, the sliding block 149 has an elastic force.

A pull rod 143 is slidably connected inside the connecting seat 145. The rotating block 13 contacts the connecting seat 145, and the connecting seat 145 is slidably connected to the slider 142. By pulling the slider 142, the slider 142 moves to the designated position. Then, the screw 12, the rotating block 13, and the annular groove 141 are installed in the designated position. Then, the slider 142 is moved into the annular groove 141, thereby limiting the screw 12 and preventing the screw 12 from loosening after long-term use of the device.
[0022] The specific implementation process of this utility model is as follows: When the device is in use, pull the handle 144 to move away from the connecting seat 145. The movement of the handle 144 drives the pull rod 143 to move. The movement of the pull rod 143 drives the elastic block 146 and the slider 142 to move. The movement of the slider 142 drives the sliding block 149 to move. The movement of the sliding block 149 compresses the spring 148. After the slider 142 and other components move to the designated position, the rotating block 13 moves towards the channel steel beam 11. The movement of the rotating block 13 drives the annular groove 141 and the screw 12 to move. The screw 12 moves and inserts into the channel steel beam 11 to contact the first steel rib plate 1. Then, the rotating block 13 is rotated, which drives the annular groove 141 and the screw 12 to rotate. The rotation of the screw 12 causes a threaded movement with the first steel rib plate 1, thereby causing the screw 12 to generate relative displacement. After the screw 12 rotates to the designated position, the handle 144 is released, and the spring 148... The elastic force causes the sliding block 149 to move, which in turn causes the slider 142 to move. The slider 142 then causes components such as the elastic locking block 146 to move. The slider 142 moves into the annular groove 141, which in turn causes the elastic locking block 146 to engage with the connecting seat 145, thereby limiting the screw 12 and preventing the screw 12 from loosening after prolonged use.
