As shown in fig. 3, the locking mechanism is now in the unlocked position. When the container needs to be locked, the driving screw 1 is reversed to synchronously drive the left moving module 21 and the right moving module 22 to move in opposite directions, so as to push the first locking member 31 and the second locking member 32 connected together through the connecting shaft 30 to rise upwards, and simultaneously, the first locking portion 311 and the second locking portion 321 perform opening movement. When the first locking member 31 and the second locking member 32 rise to the highest point, the first locking member 31 and the second locking member 32 are respectively abutted against the edge of the opening 61, and at this time, the first locking member 31 and the second locking member 32 are enclosed to form an "X" shape (see fig. 2), and the upper ends of the first locking portion 311 and the second locking portion 321 extend out above the opening 61, and the locking claw 301 of the first locking portion 311 and the locking claw 301 of the second locking portion 321 face opposite to each other, so as to assist in locking the container.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
