[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Reference Figure 1-Figure 6 A plane mirror positioning assembly shown in the figure comprises a bottom plate 1, a plurality of support columns 2 are arranged on the top of the bottom plate 1, a test table 3 is fixedly mounted on the tops of the plurality of support columns 2, a plane mirror 25 is arranged on the top of the test table 3, two circular plates 11 are arranged on the top of the test table 3 through an adjustment mechanism, the adjustment mechanism is used to adjust the position of the circular plates 11, and a measuring mechanism is arranged on the top of the bottom plate 1, the measuring mechanism is used to measure the position of the circular plates 11;

[0031] The adjustment mechanism includes two rectangular sliders 4. Two sliding holes are provided on the top of the test bench 3. The two rectangular sliders 4 are slidably installed in the two sliding holes through sliding units. A round table 10 is slidably installed in the two rectangular sliders 4 through the adjustment unit. A placement round plate 11 is provided at the top of the round table 10 through a telescopic unit. A clamping unit is provided at the top of the placement round plate 11. A square hole is provided at the top of the round table 10. A rectangular slide bar 19 is slidably installed in the square hole. The top of the rectangular slide bar 19 is fixedly installed at the bottom of the placement round plate 11. A limit plate 20 is fixedly installed at the bottom of the rectangular slide bar 19.

[0032] The measuring mechanism includes a scale 22, which is arranged on the top of the base plate 1. Two slide grooves are provided on both sides of the base plate 1. L-shaped sliders 24 are slidably installed in the four slide grooves. Two observation plates 23 are respectively arranged on the top of the four L-shaped sliders 24, and the two observation plates 23 are respectively adapted to the two limit plates 20.

[0033] like Figure 2As shown, the sliding unit includes two bidirectional screw rods 5, the two sliding holes are connected by a connecting hole, the opposite inner walls of the two sliding holes are jointly provided with a transmission groove, the two ends of the two bidirectional screw rods 5 are respectively rotatably installed on the opposite inner walls of the two transmission grooves, the two bidirectional screw rods 5 are connected by a transmission element, and the two rectangular sliders 4 are both threadedly installed on the two bidirectional screw rods 5. In this way, by rotating the two bidirectional screw rods 5, the two rectangular sliders 4 can be driven to achieve synchronous movement toward or away from each other under the action of the threads, thereby facilitating the adjustment of the lateral position of the rectangular slider 4, and the adjustment operation is convenient.

[0034] like Figure 3 As shown, the transmission element includes two sprockets 6, and the two sprockets 6 are respectively fixedly sleeved on two bidirectional screw rods 5. Chains 7 are installed on the two sprockets 6 in meshing with each other. Such an arrangement can drive the two bidirectional screw rods 5 to rotate synchronously through the meshing action of the two sprockets 6 and the chain 7, thereby preventing the rectangular slider 4 from getting stuck during movement.

[0035] like Figure 2 As shown, one end of one of the bidirectional screw rods 5 extends outside the test bench 3 and is fixedly mounted with a hand wheel 8. With this arrangement, when the bidirectional screw rod 5 needs to be rotated, convenient operation can be achieved by rotating the hand wheel 8.

[0036] like Figure 5 As shown, the adjustment unit includes two limit sliders 9, a rectangular hole is opened on the top of the rectangular slider 4, and limit sliding holes are opened on the relative inner walls of the rectangular hole. The two limit sliders 9 are respectively slidably installed in the two limit sliding holes, and the sides of the two limit sliders 9 are fixedly connected to the outer wall of the circumferential side of the table 10. In this way, when it is necessary to adjust the longitudinal position of the table 10, the adjustment function of the longitudinal position of the table 10 is realized by sliding the two limit sliders 9, and the adjustment operation is convenient.

[0037] like Figure 5 As shown, the telescopic unit includes multiple telescopic shafts 12, a circular groove is opened at the top of the truncated table 10, the top ends of the multiple telescopic shafts 12 are fixedly installed on the bottom end of the placed circular plate 11, and the bottom ends of the multiple telescopic shafts 12 are respectively slidably installed in the multiple circular grooves, and the multiple telescopic shafts 12 are sleeved with compression springs 13, the top ends of the multiple compression springs 13 are fixedly installed on the bottom end of the placed circular plate 11, and the bottom ends of the multiple compression springs 13 are fixedly connected to the top of the truncated table 10. In this way, the telescopic shaft 12 can limit the truncated table 10 when it is raised or lowered through the limiting function to prevent it from rotating, and the elastic effect of the compression spring 13 can drive the placed circular plate 11 to reset when the limiting effect on the placed circular plate 11 is released, and the stability is strong.

[0038] like Figure 5As shown, the clamping unit includes two arc-shaped fixing plates 14, and the two arc-shaped fixing plates 14 are fixedly installed on the top of the placing circular plate 11. The inner walls of the circumferential sides of the two arc-shaped fixing plates 14 are provided with through holes, and sliding shafts 15 are slidably installed in the two through holes. An arc-shaped clamping plate 16 is fixedly installed at one end of the two sliding shafts 15, and a pulling plate 17 is provided at the other end of the two sliding shafts 15. Resetting elements are provided on the two sliding shafts 15. In this way, the candle can be clamped and fixed through the elastic action of the two arc-shaped clamping plates 16 and the reset element, so that the center position of the candle corresponds to the center position of the placing circular plate 11.

[0039] like Figure 5 As shown, the reset element includes a clamping spring 18, which is sleeved on the sliding shaft 15, one end of the clamping spring 18 is fixedly installed on the outer wall of the circumference of the arc-shaped fixed plate 14, and the other end of the clamping spring 18 is fixedly installed on the side of the pull plate 17. In this way, when the limit on the pull plate 17 is released, the elastic action of the clamping spring 18 drives the pull plate 17 and the arc-shaped clamping plate 16 to realize the reset function.

[0040] like Figure 6 As shown, a zero scale line 21 is provided on the base plate 1, and the position of the zero scale line 21 corresponds to the position of the plane mirror 25. In this way, the distance between the observation plate 23 and the plane mirror 25 can be measured through the scale line 22 and the zero scale line 21 set on the top of the base plate 1.

[0041] An optical imaging device adopts the above-mentioned plane mirror positioning assembly.

[0042] The working principle of the present invention is as follows: the two pull plates 17 are pulled respectively, thereby driving the two sliding shafts 15 and the two arc-shaped clamping plates 16 to move in opposite directions, placing the candle on the top of the placing circular plate 11, and loosening the two pull plates 17. Under the elastic action of the clamping spring 18, the candle can be conveniently fixed, thereby preventing the candle from tipping over during the moving process, thereby improving the stability during use.

[0043] When the position of the candle needs to be adjusted, the bidirectional lead screw 5 is first driven to rotate by the hand wheel 8, and then the other bidirectional lead screw 5 is driven to rotate synchronously under the meshing action of the two sprockets 6 and the chain 7, so that the two rectangular sliders 4 move synchronously toward or away from each other, and the lateral position of the candle is adjusted. One of the placement circular plates 11 is pulled upward to drive the rectangular slide bar 19 and the limit plate 20 to move upward synchronously, and the extrusion between the limit plate 20 and the bottom plate 1 is released. Then, the placement circular plate 11 is slid along the rectangular hole to adjust the longitudinal position of the candle. Then, the placement circular plate 11 is released, and the placement circular plate 11 and the limit plate 20 are driven to reset downward through the elastic action of multiple compression springs 13. In this way, the position of the candle can be conveniently adjusted.

[0044] The candle image is observed through the plane mirror 25, and then the position of the other circular plate 11 and the candle is adjusted according to the above steps to make them coincide with the image of the candle, and then the two observation plates 23 are slid respectively so that their sides are respectively fitted with the sides of the two limit plates 20, and then the distance between the two limit plates 20 and the plane mirror 25 is measured by the scale 22. With this arrangement, the entire measurement process is more convenient and easy to perform actual operations.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
