[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "alignment", "overlap", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model.

[0025] The terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features; in the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0026] In order to solve the problems of great processing difficulty, difficulty in ensuring that the size meets the design requirements, poor processing technology and difficult assembly in the prior art, the embodiment provides a Figure 3 The tubular positioning block (also called rotating lock block) shown in the figure is provided with a first claw 6 and a second claw 7 at the ends of the same diameter line (this is the existing design) at one end of the tubular positioning block, and the other end of the outer wall of the tubular positioning block is provided with Figure 6 The first limiting block 8 and the second limiting block 9 at the ends of the same diameter line shown in the figure are designed to combine the existing technology of the sliding groove 4 and the sliding pin 5 (both the sliding groove and the sliding pin extend along the axial direction) into one, simplify the number of parts, and assemble conveniently and quickly, especially reduce the processing difficulty, cooperate with the positioning size, easily ensure the processing size, and have good processability, and more easily meet the assembly process requirements.

[0027] In order to achieve better assembly process, the first limiting block 8 and the second limiting block 9 provided by the embodiment are the same in structure, and are both Figure 6The arc-shaped convex part 10 in the middle, the connecting part 11 connecting the arc-shaped convex part 10 and the outer side wall of the tubular positioning block constitute. And the upper and lower ends of the connecting part 11 are tangent to the arc-shaped convex part 10 and the outer side wall of the tubular positioning block respectively. In this way, a good arc transition can be achieved, especially for the design of the front mounting bracket 2 that matches it. That is Figure 7 The shown one is a rail type rotating bracket, which includes a front mounting bracket 2 and a tubular positioning block 3 coaxially installed in the front mounting bracket 2, i.e. a tubular positioning block with a first limiting block 8 and a second limiting block 9, Figure 7 It can be found that the inner side wall of the front mounting bracket 2 is provided with a first axial sliding groove 12 and a second axial sliding groove 13 matched with the first limiting block 8 and the second limiting block 9, and by Figure 8 It can be clearly seen that the first axial sliding groove 12 and the second axial sliding groove 13 are through grooves, i.e. extending along one end of the front mounting bracket 2 to the other end, so that when the first clamping jaw 6 and the second clamping jaw 7 are assembled in Figure 9 The corresponding end wall of the rotating assembly 14, the first limiting block 8 and the second limiting block 9 are in contact with the corresponding end of the rotating assembly 14. Compared with the prior art, the rotation of the tubular positioning block 3 is prevented by the cooperation of the two notches on the annular stop ring on the inner wall of the front mounting bracket 2, the sliding groove 4 and the sliding pin 5. Only the cooperation of the first limiting block 8 and the second limiting block 9 with the corresponding first axial sliding groove 12 and the second axial sliding groove 13 is needed to prevent the rotation of the tubular positioning block 3, the structure is greatly simplified, and the machining of the first limiting block 8 and the second limiting block 9 has a larger machining size, which reduces the machining difficulty and improves the assembly simplicity and qualification rate.

[0028] The connecting screw hole on the rotating assembly 14 (also known as rotating block) is used to connect the sighting device with the rotating assembly 14, and in the use process, the sighting device drives the rotating block to rotate around Figure 9 The z-axis, at the same time, the positioning boss of the rotating block (i.e. the first clamping jaw 6 and the second clamping jaw 7 in the patent document with the patent number 202022203833.1) and the positioning groove 16 on the rotating block (i.e. the first arc-shaped stop edge or the second arc-shaped stop edge in the patent document with the patent number 202022203833.1) of the tubular positioning block slide contact, forcing the tubular positioning block to slide linearly along the Z-axis direction, when the rotating block rotates around Figure 10 The shown one is a rail type rotating bracket, which includes a front mounting bracket 2 and a tubular positioning block 3 coaxially installed in the front mounting bracket 2, i.e. a tubular positioning block with a first limiting block 8 and a second limiting block 9, Figure 11When the vertical position (90°) is shown, because the tubular positioning block is provided with the first axial sliding groove 12 and the second axial sliding groove 13 matched with the first limiting block 8 and the second limiting block 9 on the inner side wall of the rotating support structure, i.e., the front mounting support 2, the rotating block can only linearly slide along the Z-axis direction and cannot rotate in the x, y plane, and at the same time, the positioning boss (i.e., the first clamping jaw 6 and the second clamping jaw 7) of the tubular positioning block is tightly pushed into the positioning groove 16 on the rotating block 14 through the Z-axis direction locking spring 15, so as to realize the quick positioning from the horizontal position (0°) to the vertical position (90°).
