[0002] The length adjustment of the scope usually refers to adjusting the distance between the scope and the barrel to ensure that the scope is aligned with the barrel, thereby improving the accuracy of the design. This process does not directly involve the change in the length of the scope itself, but rather adjusts the installation position of the scope. Scopes of different lengths need to be replaced in different environmental situations. Firearms personnel need to adjust the position of the scope on the gun body slide rail when using it to adapt to the shooter's shooting posture and shooting habits.

[0003] According to the Chinese patent publication number CN220583205U, "A sight with an adjustable length structure", it mainly describes that by rotating the adjusting sleeve installed on the outside of the sight body, the adjusting sleeve can be rotated on the sight body through the adjusting annular groove, which is beneficial for the adjustment sleeve to drive the glass lens to extend or contract, and the overall length of the sight can be adjusted. In the process of adjusting the precise position of the sight, the position of the sight on the gun body slide needs to be constantly adjusted and connected through a limit mechanism thread. The shooter needs to constantly adjust to adapt to the shooting posture and shooting habits, which makes the adjustment more troublesome.

[0004] Therefore, a scope with an adjustable length structure is proposed to solve the problem that in the process of adjusting the precise position of the scope, the position of the scope on the gun body slide needs to be constantly adjusted and connected through a limit mechanism thread. The shooter needs to constantly adjust to adapt to the shooting posture and shooting habits, which makes the adjustment more troublesome. Utility Model Content

DETAILED DESCRIPTION

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] Please refer to Figure 1-4 The shown sight has a length-adjustable structure, comprising a gun body upper support plate 1 and a scope body 2, the scope body 2 being fixedly connected with a connecting block 3, both ends of the gun body upper support plate 1 being fixedly connected with trapezoidal blocks 7, the trapezoidal blocks 7 and the upper side structures of the sliding guide rail 5 being consistent and both being dovetail structures, which can provide a limit for the connecting block 3, the gun body upper support plate 1 being located between the two trapezoidal blocks 7 and having a trapezoidal recess 6, the gun body upper support plate 1 being located in the trapezoidal recess 6 and being rotatably connected with an adjusting rod 8, the adjusting rod 8 being threadedly connected with a sliding guide rail 5, the sliding guide rail 5 being provided with yin-yang grooves, the sliding guide rail 5 being in contact with the connecting block 3, the connecting block 3 being threadedly connected with a limiting rod 4, rotating the adjusting rod 8 can drive the sliding guide rail 5 to move, so that the position of the scope body 2 can be continuously adjusted after being connected with the scope body 2 to adapt to the shooting posture and shooting habits of the shooter.

[0019] The upper support plate 1 of the gun body is fixedly connected to the bottom side of the reinforcing rib 9 , and the reinforcing rib 9 is fixedly connected to the side of the two trapezoidal blocks 7 that are away from each other. The stability of the trapezoidal blocks 7 can be increased by providing the reinforcing rib 9 .
