When installing the support column 5, the positioning strip 4 on the support column 5 is aligned with the positioning groove 3, and then the positioning strip 4 is inserted into the inside of the positioning groove 3. The positioning strip 4 drives the support column 5 to move to the inside of the sleeve 2. A load-bearing beam 6 is provided on the top of the support column 5, and a pedal 7 is provided on one side of the load-bearing beam 6. The bottom of the pedal 7 is movably connected to a T-shaped movable column 8, and one side of the T-shaped movable column 8 is fixedly connected to a fixed column 9. When the pedal 7 is installed on the load-bearing column 6, the T-shaped movable column 8 is pulled, the pedal 7 is placed on the fixed frame 11, and then the T-shaped movable column 8 is loosened, so that the fixed column 9 moves and is inserted into the inside of the fixed frame 11.

[0030] When installing the support column 5, insert the positioning strip 4 on the support column 5 into the positioning groove 3, then rotate the fixing bolt 10 to fix the support column 5 inside the sleeve 2, and then install the load-bearing beam 6 on the top of the support column 5. When installing the pedal 7, pull the T-shaped movable column 8 through the pulling block 20 to remove the fixing column 9 from the inside of the fixing hole 14, so that the fixing groove 12 can be sleeved on the top of the fixing frame 11. At the same time, the fixing block 13 is inserted into the inside of the fixing frame 11, and then loosen the pulling block 20, so that the spring 19 pushes the limit block 18 to move, and the limit block 18 drives the T-shaped movable column 8 to move, and the T-shaped movable column 8 pushes the fixing column 9 to move and move to the inside of the fixing hole 14 again.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. When installing the pedal 7 between the two load-bearing beams 6, by pulling the T-shaped movable column 8, the T-shaped movable column 8 drives the fixed column 9 to move out from the inside of the fixing hole 14, so that the fixing groove 12 can be sleeved on the outside of the fixing frame 11, and the fixing block 13 is inserted into the inside of the fixing frame 11. Then loosen the T-shaped movable column 8. Under the push of the spring 19, the T-shaped movable column 8 drives the fixed column 9 to move to the inside of the fixing hole 14 and fixes the fixed block 13 inside the fixing frame 11. When installing the pedal 7, the operator only needs to pull the T-shaped movable column 8, which is relatively convenient to operate.

[0033] 2. When inserting the support column 5 into the sleeve 2, align the positioning strip 4 at the bottom of the support column 2 with the positioning groove 3 inside the sleeve 2, and then insert the positioning strip 4 into the positioning groove 3, so that the positioning strip 4 drives the support column 5 to move into the sleeve 2. Under the positioning of the positioning strip 4 and the positioning groove 3, the threaded holes on the support column 5 and the sleeve 2 can be directly aligned, thereby improving the efficiency of installation.
