Abstract: A laser sight is disclosed, including a housing which defines a first central axis, an objective module, an eyepiece, an erecting system, and an adjusting member. The objective module is fixed to a first end of the housing, and the eyepiece is fixed to a second end of the housing, opposite to the first end. The erecting system is movably disposed between the objective module and the eyepiece and comprises a laser rangefinder defining a second central axis. The adjusting member is movably disposed on the housing and connected to the erecting system. During windage and elevation adjustments, the adjusting member moves with respect to the housing and impels the laser rangefinder, such that the first and second axes form an included angle.

Abstract: An adjustable object lens device includes an outer barrel, a rotary component coupled movably to the outer barrel, an object lens unit disposed movably in the outer barrel, a decorative unit coupled to the rotary component, and a limiting unit. The limiting unit includes a press ring that is movably retained in the decorative ring, and that abuts against one end of the object lens unit, and a biasing member disposed in the outer barrel and abutting against the other end of the object lens unit, thereby securing the object lens unit between the biasing member and the press ring.

Abstract: An adjusting apparatus for a telescopic system includes a base unit, a rotating unit, a resilient member, and an adjusting member. The base unit includes a top wall, a bottom wall, and a surrounding wall, among which an accommodating space is defined. The rotating unit is disposed on the base unit. The resilient member is disposed between and abuts against a positioning section of the rotating unit and one of the top and bottom walls of the base unit so as to bias the positioning section to press against the other of the top and bottom walls, and has at least two circumferentially spaced-apart first contacting portions contacting the positioning section. The adjusting member is mounted threadably on the positioning section. When the rotating unit is rotated, the adjusting member moves axially relative to the base unit.
