The outer wall of the crossbeam 2 and the two sides of the column 1 are sleeved with a U-shaped plate 3. A cross plate 4 is fixedly arranged between the upper ends of the two U-shaped plates 3. The lower ends of the U-shaped plates 3 are fixedly connected with a stopper 6 through a connecting rod 5. The U-shaped plate 3, the connecting rod 5 and the stopper 6 are made of an integral molding process to improve the stability of the connection between the U-shaped plate 3, the connecting rod 5 and the stopper 6. The upper end of the column 1 L-shaped plates 7 are arranged on both sides of the ends, and the upper surfaces of the two L-shaped plates 7 are in contact with the lower surface of the crossbeam 2. A strip opening is provided on the upper end of the L-shaped plate 7, and the upper ends of the L-shaped plate 7 are respectively in contact with the corresponding U-shaped plate 3 and the stopper 6. A groove is provided on the upper side of the column 1, and through grooves are provided on both sides of the lower end of the groove. A plug-in plate 8 is fixedly provided on one side of the middle end of the L-shaped plate 7, and the plug-in plate 8 is plugged into the corresponding through groove. The longitudinal sections of the plug-in plate 8 and the through groove are both rectangular, so that the plug-in plate 8 and the through groove are more stable.

[0025] Reference Figure 1-3 A limiting mechanism for limiting the two plug plates 8 is provided inside the groove, and the limiting mechanism includes a push plate 9 and a limiting rod 10. The push plate 9 is slidably arranged inside the groove. The cross sections of the push plate 9 and the groove are both rectangular, so that the push plate 9 cannot rotate, that is, it can slide stably. The two limiting rods 10 are fixedly arranged on both sides of the lower surface of the push plate 9. Limiting holes are provided on the upper surfaces of the ends close to the two plug plates 8. The two limiting rods 10 are plugged into the corresponding limiting holes. A bolt 11 is provided on the middle threaded sleeve of the cross plate 4.
