[0046] Furthermore, a gasket 52 is provided inside the mounting frame 5, which can not only increase the tightness between the cross post 2 and the mounting frame 5, but also prevent the two from directly contacting each other and causing wear.

[0047] The working principle of this invention is as follows: When connecting the upright 1 and the horizontal column 2, the first connecting piece 3 is first connected to the upright 1, and the second connecting piece 4 is connected to the horizontal column 2. The first fixing block 33 on the first frame 31 of the first connecting piece 3 passes through the first slot 11, and the first frame 31 fits onto three sides of the upright 1. The second fixing block 34 on the second frame 32 is inserted into the second slot 35 on the first fixing block 33. After full insertion, the first rectangular block 36 and the second rectangular block 37 can be spliced ​​together. Then, the first rectangular block 36 and the second rectangular block 37 are bolted together from the top and bottom respectively. The third fixing block 43 of the second connecting piece 4 is then inserted into the horizontal column 2. Inside, the horizontal column 2 is inserted into the third slot 41. The second connector 4, the horizontal column 2, and the third fixing block 43 are connected together on both sides by bolts. Then, the second connector 4 is aligned with the mounting frame 5. The two sides of the connecting bolt of the second connector 4 are located inside the mounting frame 5. The bolts can be abutted by the inside of the mounting frame 5. The T-slot of the mounting frame 5 away from the second frame 32 can partially cover the horizontal column 2, increasing the contact surface of the connection, dispersing the force, and improving the connection strength. Then, the mounting frame 5 and the top of the second connector 4 are connected from both sides of the mounting frame 5 by bolts, thereby completing the connection between the column 1 and the horizontal column 2.
