The first cross member 4.1 and the second cross member 4.2 are in close contact with each other in the packaged state. In the mounted state, the connecting device 5 limits the relative displacement of the first cross member 4.1 and the second cross member 4.2 in the length direction of the support frame 4. In fig. 1, the X direction is the width direction of the supporting frame 4, the first beam 4.1 and the second beam 4.2, and the Y direction is the length direction of the supporting frame 4, the first beam 4.1 and the second beam 4.2.
In the above technical solution, the first beam 4.1, the second beam 4.2 and the connecting device 5 form the supporting frame 4, and the supporting frame 4 can be switched between an installation state and a packaging state. In the installed state, the end user can quickly assemble the table legs 3 and other accessories; when under the packing state, the interval of first crossbeam 4.1 and second crossbeam 4.2 dwindles, can reduce the volume when supporting frame 4 transports, reduces the packing volume, reduces the packing cost. The first cross beam 4.1 and the second cross beam 4.2 are tightly attached in a packaging state, so that the size during transportation can be reduced as much as possible, the transportation is convenient, the first cross beam 4.1 and the second cross beam 4.2 can be mutually supported in the packaging state, the deformation is not easy, and the transportation loss is reduced.
