[0054] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0055] Working principle of the present invention: When in use, the support column 1 is placed between two I-shaped steels to support the two I-shaped steels. Rotating the rotating block 20 can rotate the transmission shaft 18. The rotation of the transmission shaft 18 can rotate the transmission gear 19. The rotation of the transmission gear 19 can apply force to the rotating gear 16 in the support column 1 and make the rotating gear 16 rotate. With the rotation of the rotating gear 16 and the limit of the connecting groove 12 on the connecting block 11, the connecting plate 3 can drive the support plate 4 to slide in the inner wall of the support groove 2. After the support plate 4 slides out of the support groove 2, it can support the surface of the I-shaped steel. As the connecting plate 3 moves, the tooth plate 9 can move. The movement of the tooth plate 9 can apply force to the gear 7, and the gear 7 can rotate. Since the two gears 7 are meshed, the rotating plate 8 can rotate upward, which can increase the contact area between the support plate 4 and the I-shaped steel. Therefore, when in use, the support area of ​​the equipment on the I-shaped steel can be increased, and the support structure can be stored when not in use, achieving the effect of stable support and storage at the same time;

[0056] When the support plate 4 supports the I-shaped steel, after the positioning frame 21 is separated from the inner wall of the support groove 2, the positioning frame 21 can be pulled to make the positioning block 26 slide in the inner wall of the positioning groove 25. As the support plate 4 contacts the outer wall of the I-shaped steel, the positioning rod 23 can be rotated to make the positioning plate 24 clamped in the groove wall of the I-shaped steel, so that the groove wall of the I-shaped steel can be clamped, which can increase the support effect on the I-shaped steel;

[0057] After the rotating plate 8 contacts the surface of the I-shaped steel, the rotatable adjusting plate 29 cooperates with the rotating operation of the adjusting tooth 28, so that the adjusting plate 29 can make further contact with the surface of the steel structure, and the contact area between the equipment and the steel structure can be further increased. After the adjusting plate 29 contacts it, the limiting spring 31 allows the limiting rod 30 to be stably placed in the tooth groove of the adjusting tooth 28, so that the adjusting plate 29 can be fixed;

[0058] After the support plate 4 contacts the surface of the I-shaped steel, the movable block 36 can slide through the inner wall of the movable groove 35 under the elastic force of the movable spring 37. At this time, the worm 33 can contact the worm wheel 34, so that the equipment can be fixed and stable, and the stable operation of the support for the I-shaped steel can be guaranteed.
