Quick Disassembly Device and the Operation Method thereof

A quick disassembly device comprising:

• a first connection mechanism comprising:
• a first housing;
• a shell movably disposed on the first housing, and comprising a fastening groove, wherein the fastening groove comprises a locking segment, a connection segment, and an unlocking segment;
• a main elastic element connected to the first housing and the shell;
• and
• a second connection mechanism comprising:
• a second housing;
• a switch element movably disposed in the second housing, and comprising a latch;
• and
• a transverse elastic element connected to the second housing and the switch element,
• wherein when the first connection mechanism is connected to the second connection mechanism, the first housing contacts the second housing, the shell is at an initial position, and the latch is in the the locking segment of the fastening groove,
• as the first connection mechanism separating from the second connection mechanism, the shell is moved to an unlock position, so that the latch moves from the locking segment to the connection segment, the transverse elastic element moves the switch element, and
• after the shell is released, the main elastic element moves the shell toward the initial position, and the latch is moved to the unlocking segment.
