Wedge component is connect with left-hand thread cylinder inner thread, and No. two wedge components and left-hand thread cylinder inner wall, right-hand thread cylinder inner wall are equal
It is threadedly coupled.
Preferably, the No.1 wedge component is made of No.1 wedge fixed cylinder and No.1 prism wedge, the No.1 light
It is fixed to safety barrel to connect with left-hand thread cylinder inner thread, No.1 prism wedge two sides and the fixed company of No.1 wedge fixed cylinder inner wall
It connects.
Preferably, No. two wedge components are made of No. two wedge fixed cylinders and No. two prism wedges, No. two wedges
Shape prism two sides are fixedly connected with No. two wedge fixed cylinder inner walls.
Preferably, be equipped with left-hand thread slot on the left of No. two wedges fixed cylinder, right side is equipped with right-hand thread slot, left-hand thread cylinder with
The left-hand thread slot is threadedly coupled, and right-hand thread cylinder is threadedly coupled with the right-hand thread slot.
Be using the beneficial effect of above technical scheme: structure of the invention is a kind of axis light wedge device, actual use
In the process, the light that light source generates enters from left-hand thread cylinder side, at this moment can rotate No. two wedge fixed cylinders, rotate to the left,
The distance for shortening No.1 prism wedge and No. two prism wedges, rotates to the right, just increases No.1 prism wedge and No. two wedge shapes
The distance of prism, the side wall of connecting rod play the role of limit, and the light of light source passes through No. two wedge-shaped ribs from No.1 prism wedge
Refraction is produced after mirror, by between No. two wedge fixed cylinders adjustment No.1 prism wedges of rotation and No. two prism wedges away from
From so as to adjust the angular between No.1 prism wedge and No. two prism wedges, the light after refraction passes through semi-transparent semi-reflecting eyeglass
Being reflected into need to acquire on the object of image, and constantly adjustment just can photograph the axis light trace image of no hot spot, in conclusion this
That invents is simple and reasonable, and manufacturing cost is low, by rotating left and right No. two wedge fixed cylinders, so as to adjust No.1 prism wedge
The purpose of ideal image collection is obtained to reach elimination hot spot with the angular of No. two prism wedges.

Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and facilitate its implementation.
Fig. 1 and Fig. 2 show a specific embodiment of the invention: a kind of axis light wedge device, including screw thread cartridge module 1,
No.1 wedge component 2 and No. two wedge components 3, the screw thread cartridge module 1 is by left-hand thread cylinder 11, right-hand thread cylinder 12 and connecting rod 13
Composition, described 13 one end of connecting rod are fixedly connected with 11 outer wall of left-hand thread cylinder, and the other end is fixedly connected with 12 outer wall of right-hand thread cylinder,
The No.1 wedge component 2 is connect with 11 inner thread of left-hand thread cylinder, No. two wedge components 3 and 11 inner wall of left-hand thread cylinder,
12 inner wall of right-hand thread cylinder is threadedly coupled.
In the present embodiment, the No.1 wedge component 2 is made of No.1 wedge fixed cylinder 21 and No.1 prism wedge 22, institute
It states No.1 wedge fixed cylinder 21 to connect with 11 inner thread of left-hand thread cylinder, 22 two sides of No.1 prism wedge and No.1 wedge are solid
21 inner wall of safety barrel is fixedly connected, as shown in Figure 2.
In the present embodiment, No. two wedge components 3 are made of No. two wedge fixed cylinders 31 and No. two prism wedges 32, institute
It states No. two 32 two sides of prism wedge to be fixedly connected with No. two 31 inner walls of wedge fixed cylinder, No. two prism wedges 32 and No.1 wedge shape rib
Mirror 22 forms prism wedge group, realizes the refraction of light source light.
In the present embodiment, left-hand thread slot 31-1 is equipped on the left of No. two wedge fixed cylinders 31, right side is equipped with right-hand thread slot
31-2, left-hand thread cylinder 11 are threadedly coupled with the left-hand thread slot 31-1, and right-hand thread cylinder 12 and the right-hand thread slot 31-2 screw thread connect
