Shell structure

The embodiment of the invention provides a shell structure, and relates to the technical field of shell structures. The shell structure provided by the embodiment of the invention comprises a first shell, a second shell, a sliding block and a locking piece. The first shell and the second shell are buckled in a first direction, and therefore, a containing cavity is formed in the first shell and the second shell. A sliding block is in sliding fit with a fixing block, and the sliding block is used for driving the fixing block to move in the first direction under the condition that the sliding block moves in the second direction relative to the fixing block, so that the first shell has the tendency of moving close to the second shell in the first direction. As the shell structure is provided with the sliding block, a force pointing to the second shell body is applied to the first shell body when the sliding block moves in the second direction, the first shell body has a trend of moving toward the second shell bod
