[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When working, the folding rod 34 is first pressed to cause the surface of the folding column 37 to slide to the rectangular groove position on the surface of the annular groove 36. At this time, the inner surface of the folding groove 35 is disengaged from the inner protrusion of the support frame 1. At this time, the folding rod 34 can be rotated. The rotation of the folding rod 34 drives the connecting block 33 to rotate downwardly toward the support frame 1. When the connecting block 33 and the support frame 1 are rotated to be flush with each other, the folding rod 34 is released. The folding rod 34 will move outward under the action of the sliding spring 62, causing the inner surface of the folding groove 35 to contact with the inner protruding surface of the support frame 1, limiting the further rotation of the folding rod 34. The same operation is performed to unfold each structure, and the card block 2 is slid to the connecting block 33.
