[0018] See also Figure 1-3 As shown, a housing structure of an optoelectronic instrument that is easy to disassemble and assemble includes a housing 1. A plurality of plug-in holes 13 are distributed on the inner wall of the housing 1, and the plug-in holes 13 are interconnected through side channels 14. The side channels 14 are connected to the inner space of an integrated block 17, and two holes 16 are connected to the outside of the integrated block 17. A rear cover plug-in edge block 11 is provided at the inner edge of the rear end shell opening of the housing 1, and a plug-in card slot 12 is provided on the surface of the rear cover plug-in edge block 11.
