Among them, the upper locking nut 23 is embedded in the first groove 21, and the upper locking nut 23 is threadedly connected to the upper end of the corresponding column 30. Make the overall structure of the frame more stable.

[0021] The base 10 has a second countersunk hole 11 and a second groove 12 communicating with the second countersunk hole 11 at a position corresponding to the first countersunk hole 22. The second countersunk hole 11 is a through hole, and the second countersunk hole 11 and the second groove 12 are coaxially arranged. Each second groove 12 is sleeved on the lower end of the corresponding column 30. A lower locking nut 13 is embedded in the second groove 12, and the lower locking nut 13 is threadedly connected to the lower end of the corresponding column 30. The lower locking nut 13 is fixed to the base 10 by bolts. In this way, the base and the column will not loosen.

[0022] In addition, each column 30 is fixed to the upper cross beam 20 via a fixing mechanism 40 .
