In various embodiments of the present invention, the supporting leg 3 may be connected to one or more first beams 1 and one or more second beams 2 according to need, which is not limited to the present invention.
In some embodiments of the present invention, a first step 441 is disposed on a side of the first protrusion 44 opposite to the second protrusion 45, so that the first protrusion 44 engages with a sidewall of the first through hole 11 where the first beam 1 is disposed when inserted into the first through hole 11. A second step 451 is provided on a side of the second protruding portion 45 opposite to the first protruding portion 44 so that the second protruding portion 45 engages with a sidewall of the second through hole 21 provided on the second beam 2 when inserted into the second through hole 21. Thereby, the first and second protrusions 44 and 45 are made to be hook-shaped protrusions, thereby reinforcing the connection strength between the connection member 4 and the first and second beams 1 and 2.
In some embodiments of the invention, the cross section of the connecting piece 4 on the plane formed by the bisectors of the first beam 1 and the second beam 2 and the supporting leg 3 is a U-shaped connecting piece that opens towards the supporting leg 3.

One end of the first beam 1 connected with the supporting leg 3 is adapted to the outer side wall of the supporting leg 3, and a third protruding portion 12 clamped into the first notch 32 is provided. Thereby, it is possible to provide a limit to the first beam 1 and the support foot 3 and to strengthen the connection strength. One end of the second beam 2 connected with the supporting leg 3 is adapted to the outer side wall of the supporting leg 3, and a fourth protruding portion 22 clamped into the second notch 33 is provided. Thereby, it is possible to provide a limit to the second beam 2 and the support foot 3 and to strengthen the connection strength.
In some embodiments of the present invention, the first beam 1 is further provided with a first avoidance groove 13 to avoid the third through hole 31 when the supporting leg 3 is connected, so as to prevent the fastener 5 from being obstructed from penetrating into the third through hole 31 after passing through the fourth through hole 46. The second beam 1 is further provided with a second avoidance groove 23 to avoid the third through hole 31 when the supporting leg 3 is connected, so that the fastener 5 is prevented from being blocked from penetrating into the third through hole 31 after passing through the fourth through hole 46.
The foregoing merely illustrates various embodiments of the present invention, and the present invention is not limited thereto, and those skilled in the art can implement more modifications within the scope of the present invention without departing from the spirit of the present invention, and the modifications are not repeated herein.
