[0048] The first unlocking arm 121 and the second unlocking arm 122 are respectively rotatably arranged on the first rotating seat 112a and the second rotating seat 112b through the first rotating part and the second rotating part, and are limited by the torsion spring so that the first releasing part and the second releasing part in their initial state will not apply force to the locking tongue assembly, and the first stop block 121d and the second stop block respectively limit the first releasing part and the second releasing part from moving too far away from the locking tongue assembly.

[0049] After the transfer is completed, the first unlocking arm 121 and the second unlocking arm 122 are respectively located on both sides of the linkage arm 13, more specifically, on both sides of the inclined surface of the linkage arm 13, and the working surfaces of the first release portion 121a and the second release portion are close to the unlocking hole 213 of the lock tongue assembly. When the button 141 is pressed, the pressing connecting column 142 is pressed downward to drive the pressing portion 131 to move, thereby causing the linkage portion 133 to apply a downward force to the first working portion 121c and the second working portion. At this time, the first working portion 121c and the second working portion overcome the torsion force of the torsion spring and move downward, so that the first release portion and the second release portion apply force to the lock tongue assembly, thereby achieving unlocking.

[0050] In order to prevent debris from entering through the fitting between the button and the cover bracket and causing a cover opening failure, a pressing retaining ring 140 with a hollow structure in the middle is buckled on the raised portion arranged around the top of the mounting cavity of the reserved mounting portion 21 of the unlocking mechanism.

[0051] The locking tongue assembly is unlocked or locked by the cooperation among the unlocking release assembly 12, the linkage arm 13 and the pressing assembly 14, which not only effectively improves the synchronization of opening the two box covers, but also has a simple structure, convenient operation, better stability, and good market prospects.

[0052] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
