[0044] As shown in Figures 2 and 3, the actuating assembly 5 includes an actuating rod 50 slidably attached to the cover 2 at one end, and two actuating blocks 51 attached to the actuating rod 50. The two actuating blocks 51 move between a retracted position and an extended position. In the retracted position, the two actuating blocks 51 retract into the groove of the actuating rod 50, so that when the actuating rod 50 moves upward from closing to opening the cover 2, the two actuating blocks 51 pass between the two protrusions 410. In the extended position, the two actuating blocks 51 extend from the groove of the actuating rod 50, so that when the actuating rod 50 moves downward from opening to closing the cover 2, the two actuating blocks 51 squeeze the two protrusions 410, thereby moving the two clamps 40 from the clamped position to the released position.

[0045] As shown in FIG1 and FIG2 , the actuating assembly 5 further includes a first restoring element 52 disposed between each actuating block 51 and the actuating rod 50 .

When the lid 2 is opened from closed to open, the two clamps 40 are kept in the clamped position by the second reset element 53. When the lid 2 is opened to closed, the two clamps 40 are moved from the released position to the clamped position by the second reset element 53.

[0048] As shown in FIG. 2 and FIG. 3 , the second restoring element 53 is a tension spring.
