[0056] Furthermore, a positioning ring 202a is provided at the lower end of the cover plate 202, and the size of its outer wall is consistent with the size of the inner wall of the box body 201. There is also a clamping block 202b provided at the lower end of the cover plate 202 in the internal area of ​​the positioning ring 202a. Its shape is L-shaped, with the vertical section connected to the cover plate 202 and the horizontal section pointing to the switch slot 201a, and the width is half of the switch slot 201a.

[0057] Furthermore, a positioning block 202c is provided at the lower end of the cover plate 202, which is arranged opposite to the positioning ring 202a, and a sliding groove 202c-1 is correspondingly provided on the opposite surfaces of the two.

[0058] Furthermore, the opening and closing component 301 includes a switch 301a and an elastic gasket 301b. The switch cooperates with the switch slot 201a.

The front end of the pressure plate 302b can cooperate with the clamping block 202b.

[0061] It should be noted that the sliding length of the rotating shaft rod 302a in the sliding groove 202c-1 is greater than twice the width of the block 202b.

When the transfer box needs to be closed, the cover plate 202 is closed to make the positioning ring 202a cooperate with the box body 201, and then the pushing blocks 301a-1 on both sides of the box body 201 are pushed. During the cooperation between the locking block 301a-4 and the block 202b, the locking block 301a-4 simultaneously pushes the end of the pressure plate 302b. When the switch 301a and the block 202b are fully cooperated, the pressure plate 302b is also completely separated from the block 202b. , driven by the torsion spring 302c, it rotates along the shaft rod 302a, giving a downward pressure to the items placed in the transfer box to ensure the stability of the items; when the transfer box needs to be opened, the pushing blocks 301a-1 on both sides of the box body 201 are pushed in the opposite direction, the switch 301a is disengaged from the block 202b, and the pressure plate 302b pushes the cover plate 202 to rise and disengage from the box body 201 due to the elastic force of the torsion spring 302c, completing the opening of the transfer box. After opening, the pushing plate 302b-2 is manually pushed to make the pressure plate 302b cooperate with the block 202b for the next use.

[0064] In summary, the opening and closing component can adjust the clamping component while opening and closing the box body and the cover, so that in the closed state the clamping component can clamp the items placed inside to ensure the stability of the items during transportation. At the same time, the clamping component can also make the opening process of the transfer box smoother.
