[0027] Working principle: When installing the crossbeam 1, it is only necessary to align the open groove 2 on the crossbeam 1 with the connecting seat 3 and snap it in. Due to the setting of the inclined surface on the buckle 5 and under the action of the restoring force of the first spring 8, when the crossbeam 1 is snapped into the connecting seat 3, the buckle 5 will automatically shrink into the interior of the connecting seat 3. When the slot 4 corresponds to the buckle 5, the buckle 5 will automatically snap into the slot 4, completing the automatic fixation of the crossbeam 1. There is no need for the cumbersomeness brought by connecting with bolts, and under the action of the elastic gasket 20, it can be ensured that the crossbeam 1 does not wear the contact surface with the steel column 10 during installation. When the crossbeam 1 is fixed, the support rod 15 is flipped by the elastic gasket 20, and the pressure block 14 is pressed at the same time to drive the two L-shaped plugs 13 along the sliding column 16. Move towards each other and compress the second spring 17, then insert the support rod 15 into the opening 11 as a whole, and when the L-shaped plug 13 on the support rod 15 corresponds to the socket 12, release the pressure block 14, and under the action of the restoring force of the second spring 17, the L-shaped plug 13 automatically snaps into the socket 12, and the support rod 15 can complete the stretching and fixation of the beam 1, thereby improving the stability of the overall structure. When the beam 1 needs to be removed, it is only necessary to press the pressure block 14 and flip the support rod 15 to release the restriction effect of the support rod 15 on the steel column 10, and by pulling the pull block 9, drive the buckle 5 to retract into the connecting seat 3, and compress the first spring 8, thereby releasing the restriction effect of the buckle 5 on the beam 1, and the beam 1 can be quickly removed, which is simple and convenient.
