A sliding groove extending longitudinally is provided on an outer side of each side wall. The airtight box is further provided with an opening and locking mechanism slidably connecting the cover and the box body. The opening and locking mechanism is provided with a pushing member slidably fixed in the sliding groove and a connecting rod rotatably fixed on the pushing member and mounted inside the cover.
