[0037] Example:

[0038] This embodiment provides a sight, such as Figure 1 As shown, the scope specifically includes an objective lens unit 1, an operating lever 2, and an eyepiece unit 3. The objective lens unit 1 and eyepiece unit 3 are tubular in shape and are generally coaxially arranged. The objective lens unit 1 is rotatably mounted at one end of the operating lever 2, and the eyepiece unit 3 is mounted at the other end. The user observes through the eyepiece unit 3 while simultaneously controlling the rotation of the objective lens unit 1 to adjust the focal length of the scope. The specific structure, interrelationship, and working principle of the objective lens unit 1, operating lever 2, and eyepiece unit 3 are existing technologies and will not be described further in this embodiment.

[0039] Unlike existing technologies, the scope in this embodiment also includes a focusing clamp 4, such as... Figure 4 and Figure 6 As shown, the focusing clamp 4 includes a clamp ring 41 and a locking element 42.

[0040] The hoop 41 is generally C-shaped and has a certain degree of elasticity. Its two ends extend radially outward to form a first locking rod 411 and a second locking rod 412. The locking member 42 has an annular portion 421, the shape of which includes, but is not limited to, a circular ring or a triangular ring. The first locking rod 411 is at least partially located in the middle of the annular portion 421, and the second locking rod 412 is also at least partially located in the middle of the annular portion 421. The first locking rod 411 and the second locking rod 412 simultaneously press against the inner wall of the annular portion 421. In other words, the annular portion 421 can limit the first locking rod 411 and the second locking rod 412 and reduce the distance between them, thereby causing the hoop 41 to deform and reduce its inner diameter. Simultaneously, the locking member 42 is also positioned radially outward of the hoop 41 via the first locking rod 411 and the second locking rod 412. Figure 1As shown, the inner diameter of the hoop 41 is reduced to be clamped on the outer wall of the objective lens unit 1, so that the hoop 41 and the objective lens unit 1 are rotated synchronously, and the user can also control the rotation of the objective lens unit 1 by rotating the locking member 42 to focus. Compared with the scheme of directly rotating the objective lens unit 1, the rotation arm of the locking member 42 can be longer, so that the user is more labor-saving during focusing.

[0041] In addition, since the focusing hoop 4 and the objective lens unit 1 are in a split structure, the scope of the embodiment can be directly installed with the focusing hoop 4 on the basis of the prior art to obtain, thereby reducing the production cost.

[0042] As preferred, as shown in the drawings, Figures 5-7 As shown, the first locking rod 411 has a first threaded segment 413, the second locking rod 412 has a second threaded segment 414, the first threaded segment 413 and the second threaded segment 414 are spliced to form a threaded column 415, the threaded column 415 is located in the annular portion 421, the inner wall of the annular portion 421 is provided with a thread, and the threaded column 415 is threadedly connected with the inner wall of the annular portion 421 to prevent the locking member 42 from falling off the first locking rod 411 and the second locking rod 412. It is easy to understand that if the annular portion 421 is to be threadedly connected, the inner wall surface shape thereof should be designed as a cylindrical surface, and an internal thread is provided on the cylindrical surface.

[0043] Further preferably, the first locking rod 411 further has a first connecting segment 416 located between the first threaded segment 413 and the end of the hoop 41, and the two ends of the first connecting segment 416 are respectively elastically connected to the end of the first threaded segment 413 and the end of the hoop 41; the second locking rod 412 further has a second connecting segment 417 located between the second threaded segment 414 and the end of the hoop 41, and the two ends of the second connecting segment 417 are respectively elastically connected to the end of the second threaded segment 414 and the end of the hoop 41. Wherein, in the direction from the radial inner side of the hoop 41 to the radial outer side, the spacing between the first connecting segment 416 and the second connecting segment 417 gradually decreases, in other words, the closer to the end of the hoop 41, the smaller the spacing between the first connecting segment 416 and the second connecting segment 417.

[0044] Specifically referring to Figure 6 and Figure 7 At this time, the spacing between the locking member 42 and the hoop 41 is far, the first connecting segment 416 and the second connecting segment 417 are not in contact and extrusion with the inner wall of the annular portion 421, and the inner diameter of the hoop 41 is φ1. Combined with Figure 8 and Figure 9, rotating the locking member 42, the locking member 42 can gradually approach the hoop 41 by the thread cooperation between the inner wall of the annular portion 421, in the process, the end face of the annular portion 421 adjacent to the hoop 41 gradually extrudes the first connecting section 416 and the second connecting section 417, the first connecting section 416 and the second connecting section 417 gradually enter the annular portion 421 by the deformation of the respective end portions, and thus the first connecting section 416 and the second connecting section 417 approach each other, at the same time, the two ends of the hoop 41 are further approached, the inner diameter of the hoop 41 is further reduced and becomes φ2. In other words, by changing the number of rotation of the locking member 42, the extrusion degree of the end face of the annular portion 421 to the first connecting section 416 and the second connecting section 417 can be changed, and then the adjustment of the inner diameter of the hoop 41 is realized, so as to allow the hoop 41 to adapt to the objective lens unit 1 with different outer diameters, and the versatility of the focusing clamp 4 is improved.

[0045] Specifically referring to Figure 8 and Figure 9 , as preferred, the locking member 42 further has a limiting portion 422, the limiting portion 422 is located at the end face of the annular portion 421 away from the hoop 41. After the limiting portion 422 abuts against the end portion of the threaded column 415, it cannot further approach the hoop 41, at this time, the threaded column 415 plays a limiting effect on the locking member 42, avoiding the end portions of the first connecting section 416 and the second connecting section 417 from being excessively deformed and broken.

[0046] It is not difficult to understand that in the embodiment, the locking member 42 is a screw cap. In some other embodiments, the locking member 42 only has the annular portion 421, and the locking member 42 can be a nut.

[0047] Again referring to Figure 5 , Figure 7 and Figure 9 , the side wall of the first threaded section 413 is provided with a clamping groove 418, and the side wall of the second threaded section 414 is convex to form a clasp 419, the user can first single-handedly buckle the clasp 419 in the clamping groove 418 to prevent the first threaded section 413 and the second threaded section 414 from being separated, and then single-handedly install the locking member 42 to the threaded column 415. The cooperation of the clasp 419 and the clamping groove 418 allows the user to single-handedly realize the installation process of the focusing clamp 4.

[0048] Referring to Figure 2 and Figure 4 , the outer wall of the annular portion 421 in the embodiment is provided with a first anti-skid tooth 423. In the process of rotating the locking member 42 to adjust the inner diameter of the hoop 41, and in the process of rotating the locking member 42 to drive the objective lens unit 1 to rotate, the first anti-skid tooth 423 can effectively play an anti-skid effect.

[0049] As Figure 2 and Figure 5As shown, the inner wall of the hoop 41 is provided with second anti-skid teeth 4110, which can increase the clamping effect of the hoop 41 on the objective lens unit 1. Figure 2 and Figure 3 As shown, the outer wall of the objective lens unit 1 is provided with third anti-skid teeth 11. By adjusting the position of the hoop 41 on the objective lens unit 1 and making the second anti-skid teeth 4110 and the third anti-skid teeth 11 contact, the clamping effect of the hoop 41 on the objective lens unit 1 can be further improved, and it is ensured that the hoop 41 and the objective lens unit 1 can rotate synchronously when the lock 42 is actuated.

[0050] The hoop 41 is spaced apart from the end face of the objective lens unit 1, so as to avoid blocking the field of view of the objective lens unit 1 during the actuation of the lock 42.

[0051] Referring to Figure 2 and Figure 3 , the operating rod 2 further comprises an end cover 5 hinged at the end face of the objective lens unit 1, so as to block or avoid the field of view of the objective lens unit 1. Since the hoop 41 is spaced apart from the end face of the objective lens unit 1, the end cover 5 is also spaced apart from the hoop 41, so as to avoid the interference of the rotation of the hoop 41 with the end cover 5.

[0052] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0053] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
