[0051] Example 2

[0052] The first stopper 72 is provided with a first slide groove, and the first stopper 72 is provided with a first protrusion adapted to the first slide groove. The limit slide 71 slides and cooperates with the first slide groove through the first protrusion. In this embodiment, the first stopper 72 is only provided on one side of the limit slide 71. The first stopper 72 is preferably in the shape of a straight line. The first stopper 72 is located on the side of the limit slide 71 close to the front side plate 1, so that the limit slide 71 can be limited in the width direction in the cavity where it is located, and the limit slide 71 can only move along the length direction of the cavity.

[0055] Example 4

[0056] like Figure 6As shown, the present embodiment provides a foldable file box based on the embodiment 1, and the structure of the file box is the same as that of the embodiment 1, wherein the limiting member includes a first limiting piece 72 and a third limiting piece 74, the first limiting piece 72 is located on the side of the limiting slider 71 close to the front side plate 1, and the second limiting piece 73 is located on the side of the limiting slider 71 close to the rear side plate 2, and a third protrusion 714 adapted to the third limiting piece 74 is provided on the limiting slider 71. Different from the structures of the first two limiting members, the present embodiment respectively provides the first limiting piece 72 and the third limiting piece 74 on both sides of the limiting slider 71, and the third limiting piece 74 is preferably in a straight line shape. By providing the third protrusion 714 on the side of the limiting slider 71 close to the third limiting piece 74, the limiting slider 71 slides through the third protrusion 714 and abuts against the third limiting piece 74 to achieve sliding limitation, thereby preventing the limiting slider 71 from sliding out of the chamber due to excessive sliding range, making the sliding smoother, more labor-saving, and cost-saving.
