Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the embodiments of the drawings.
[0025] Such as Figure 1 to Figure 7 As shown, the sight includes a bracket 10 and a collimator window 20 connected to the bracket, wherein an inner sleeve 30 is axially inserted in the collimator window, and the collimator 40 is fixed on the inner wall of the inner sleeve 30. The head extends toward the center of the inner sleeve 30 (also the center of the quasi-core window), and one end of the optical fiber 50 is wound on the outer peripheral wall of the inner sleeve 30. In order to avoid abrasion of the optical fiber 50 when the inner sleeve 30 rotates, a groove 301 is opened on the outer peripheral wall of the inner sleeve 30, and the optical fiber 50 is arranged and wound in the groove 301 in sequence, that is, the optical fiber 50 is accommodated in the groove 301. At the mouth of the groove 301; the other end of the optical fiber 50 passes through ...
