[0084] When the box door 3 is closed, the locking tongue 411 can respectively abut against the first locking block 35 and the second locking block 36, thereby driving the first locking block 35 and the second locking block 36 to rotate respectively, so as to push open the first locking block 35 and the second locking block 36, make the locking tongue 411 extend into the area between the first locking block 35 and the second locking block 36, and enable the locking tongue 411 to be clamped between the first locking block 35 and the second locking block 36, preventing the locking tongue 411 from disengaging from the locking groove 331, and thus the box door 3 can be locked.

[0085] When the locking rod 41 rotates, the locking tongue 411 can rotate and disengage from between the first locking block 35 and the second locking block 36, so that the locking tongue 411 can disengage from the locking groove 331, and thus the box door 3 is unlocked.
