Example Embodiment
[0023] Example 1, see image 3 The retractable fixing structure between the telescopic sleeve 2 and the box body 1 is as follows: the telescopic direction of the telescopic sleeve 2 is set as the axial direction of the bottom box, and the inner sides of the two opposite sides of the box body 1 are respectively provided with A number of transverse grooves 7 perpendicular to the axial direction of the bottom box, the outer sides of the two opposite sides of the telescopic sleeve 2 are respectively provided with a number of transverse convex strips 8 perpendicular to the axial direction of the bottom box. The shape and size of the lateral grooves 7 are matched, and the number of the lateral protruding strips 8 is less than the number of the lateral grooves 7 , and the lateral protruding strips 8 fall into the lateral grooves 7 . In this way, as long as a certain amount of force is used to push the telescopic sleeve 2 toward the box body 1, the transverse protruding strips 8 of th...
Example Embodiment
[0024] Example 2, see Figure 4 , the retractable fixing structure between the telescopic sleeve 2 and the box body 1 is as follows: it also includes a positioning bolt 9, a positioning block 10 is provided on the inner side of the side surface of the telescopic sleeve 2, and the inner side of the side surface of the box body 1 , There is a support block 11 near the bottom surface of the box body 1. Generally speaking, the telescopic sleeve 2 and the bottom surface of the box body 1 have a certain distance, so the inner side of the side between the telescopic sleeve 2 and the bottom surface of the box body 1 can be set Positioning block 10. The positioning bolt 9 is rotatably fixed to one of the positioning block 10 or the supporting block 11 , and is threadedly connected to the other of the positioning block 10 or the supporting block 11 . In this way, the distance between the positioning block 11 on the inner side of the telescopic sleeve 2 and the support block 12 on the i...
