When the combined left side plate 13, the combined right side plate 14 and the combined front shell 11 are connected, the front locking fixing piece 115 on the combined front shell 11 is inserted into the locking mechanism 17 and abuts against the pull hook 1741. One end of the pull hook 1741 is beveled. When the front locking fixing piece abuts against the beveled surface of the pull hook 1741, the pull hook 1741 drives the locking pull rod 174 to rotate and stretch the tension spring 1744 at the same time. As the front locking fixing piece continues to penetrate, the front clamping hole 1151 is opposite to the pull hook 1741. The tension spring 1744 resets to pull the locking pull rod 174 to reset, so that the pull hook 1741 is clamped into the inside of the front clamping hole 1151 and hooks the front locking fixing piece 115.

The locking pull rod 174 deflects to stretch the tension spring 1744. At the same time, the locking pull rod 174 drives the pull hook 1741 to separate from the rear locking fixing piece 155 and the front locking fixing piece 115. Then, the combined rear shell 15, the combined left side plate 13, the combined right side plate 14 and the combined front shell 11 can be disassembled in sequence. One end of the central rotating shaft 173 is hexagonal. The central rotating shaft 173 can be rotated by using a hexagonal screwdriver.

[0058] As a specific technical solution of the embodiment, the combined cover 16 comprises a cover body 161. The bottom of the cover body 161 is movably clamped with a tobacco slice box 162.
