Both hands hold the C-shaped structure through the preset gap, which is comfortable and fits, and the grip is tighter.
[0035] In a possible implementation, only one end of the cross section of the quadrangular prism structure of the housing 100 is provided with a C-shaped structure, and at least one limiting portion 200 is provided. The limiting portion 200 is disposed close to the protrusion of the housing 100C structure.
[0036] In a possible implementation, the protection portion is slidably connected to the connecting belt, and a sliding direction of the protection portion is consistent with a length direction of the connecting belt.
[0037] In a possible implementation, the protection portion is provided with two through holes, which match the connecting belt, one end of the connecting belt in the length direction is fixed to the housing 100, and the other end passes through the two through holes in sequence and is fixed to the housing 100. The two ends of the connecting belt are located at the two ends of the same side of the prism structure of the housing 100 along the observation direction of the night vision device.
[0038] In a possible implementation, both ends of the limiting portion 200 are detachably connected to the outer side wall of the housing 100, so that if the limiting portion 200 is damaged, it is easy to replace it.
