A limiting head 19 is preset on the other end of the limiting frame 15. The extension member 13 is arranged on the fixture 12, and the extension member 13 is movably connected to the fixture 12.

[0055] The fixture 12 moves on the outer ring of the magnifying glass barrel 1 to facilitate adjusting the posture and position of the fixture 12 so as to be able to clamp the magnifying glass barrel 1 at a suitable position. The magnifying glass barrel 1 is inserted into the inner side of the fixture 12.

[0056] The number of auxiliary components is three to six, and they are all located on the upper side of the fixture 12;

[0057] The auxiliary component can move on the magnifying glass barrel 1 together with the fixture 12.

[0058] The expansion piece 13 includes a second base plate 29 which is installed on the fixture 12. Four first support columns 30 are installed on the second base plate 29.

[0059] The second base plate 29 can be fixed at any position around the fixture 12 in a circle. Thus, the expansion piece 13 can be installed at any position on the fixture 12. A guide rail is provided on the expansion piece 13 for installing auxiliary equipment.

[0060] The inner ring of the fixture 12 is installed with evenly distributed gas springs 25.

[0061] The size of the gas spring 25 is variable to adapt to magnifying glass barrels 1 with different outer diameters, so that the fixture 12 can firmly clamp the magnifying glass barrel 1. The elastic force of the gas spring 25 provides the clamping pressure.

[0062] The first fixture part 20 is a half-ring, the second fixture part 21 and the third fixture part 22 are quarter-rings. The first fixture part 20, the second fixture part 21 and the third fixture part 22 form a complete circle.

[0063] The first fixture part 20 is screwed to the second fixture part 21, and the first fixture part 20 is screwed to the third fixture part 22.

[0064] The fixture 12 further includes a structural ring which is installed on the flat surface of the fixture 12. An annular rack 27 is installed on the structural ring. Two of the first gears 28 on the expansion piece 13 engage with the annular rack 27.

[0065] The expansion piece 13 moves along the annular rack 27 by means of the first gear 28, causing the expansion piece 13 to rotate around the fixture 12.

[0066] The auxiliary component includes a first base plate 14 and a connection unit. The first base plate 14 is connected to the fixture 12. The connection unit is installed on the first base plate 14 and is movably connected to the magnifying glass barrel 1.

[0067] The connection unit includes a second swing arm 17, an angle locking member 18 and a first swing arm 16. One end of the limit frame 15 is screwed to the first base plate 14, and a limit head 19 is installed at the other end. The size of the limit frame 15 is variable.

The other end of the first swing arm 16 is fixedly connected to the end of the limit frame 15 near the limit head 19.

[0069] The angle locking member 18 controls the swinging of the second swing arm 17. The second swing arm 17 causes the limit heads 19 to approach each other through the first swing arm 16, and the limit heads 19 are abutted against the outer periphery of the camera barrel 2. The camera barrel 2 is limited by the limit heads 19 on multiple groups of auxiliary components, so that the camera barrel 2 is relatively locked with the magnifying glass barrel 1.

[0070] The auxiliary component includes a second support column 31 and a locking member. The second support column 31 is installed on the first base plate 14. The first base plate 14 is fixedly connected to the second support column 31 through the locking member. The second support column 31 is installed on the first base plate 14, and a second gear 32 is installed on each of the second support columns 31;

[0071] Two of the second gears 32 are engaged with the annular rack 27;

[0072] The fixture 12 includes a first fixture member 20, a second fixture member 21, a third fixture member 22, a first micro servo cylinder 23 and a second micro servo cylinder 24. One end of the first fixture member 20 is screwed with a first micro servo cylinder 23, and the other end is screwed with the second micro servo cylinder 24. The first micro servo cylinder 23 is screwed with the second fixture member 21, and the third fixture member 22 is screwed with the second micro servo cylinder 24.

[0073] The first micro servo cylinder 23 and the second micro servo cylinder 24 respectively control the swinging of the second fixture member 21 and the third fixture member 22, so that the second fixture member 21 and the third fixture member 22 are closed or separated. The closed second fixture member 21 and third fixture member 22 and the first fixture member 20 form the fixture 12;

[0074] A number of magnifying convex lenses are installed in the magnifying glass barrel 1.

[0075] The fixture 12 tightly clamps the lens barrel, and then uses several auxiliary components to embrace the camera barrel 2, so that the camera barrel 2 is limited and then docked with the magnifying glass barrel 1, so that the magnifying glass barrel 1 and the camera barrel 2 are adapted. The magnified image of the magnifying glass barrel 1 is recorded by the camera barrel 2. The clamping range of the auxiliary components is wide and the clamping is relatively stable.

[0076] The fixture 12 is installed on a carrier. The carrier includes a chassis 3, a vertical cylinder 4, a movable column 5, a cylinder 6, a mounting block 7, a circular cylinder 8 and a connecting column 9. The vertical cylinder 4 is installed on the upper side of the chassis 3. The movable column 5 is movably inserted into the vertical cylinder 4.

[0080] An elastic disc two is arranged on one side of the gear two 32 away from the support column two 31. The annular rack 27 can be clamped by the elastic disc two and the support column two 31.

[0081] The specific implementation manner is as follows: The magnifying glass lens barrel 1 is quickly limited by the fixture 12, so that the installation of the lens barrel can be completed efficiently. By controlling the clamping degree of the fixture 12, the limiting effect of the fixture 12 can be relaxed so that the magnifying glass lens barrel 1 can rotate and move; The micro servo cylinder one 23 and the micro servo cylinder two 24 control the separation and closing of the fixture part three 22 and the fixture part two 21. The limiting head 19 can limit and position the camera lens barrel 2, so that the magnifying glass lens barrel 1 is correspondingly connected to the camera lens barrel 2. The camera lens barrel 2 records the magnified image of the magnifying glass lens barrel 1, which is convenient for projection observation and storage;

[0082] The annular rack 27 on the structural ring can work normally when the fixture part three 22 and the fixture part two 21 are separated and closed;

[0083] Adjust the position of the bottom plate one 14 on the fixture 12 to make the auxiliary components arranged in a suitable position. Then control the docking of the camera lens barrel 2 and the magnifying glass lens barrel 1. Then, through the angle locking member 18, control the activities of the swing arm two 17 and the swing arm one 16. Control one end of the limiting frame 15 close to the limiting head 19 to approach the outer surface of the camera lens barrel 2. Through several auxiliary components, the positions of the camera lens barrel 2 and the magnifying glass lens barrel 1 are relatively fixed. Thus, the lens of the camera lens barrel 2 is adapted to the eyepiece of the magnifying glass lens barrel 1, and the camera lens barrel 2 can record the content magnified and displayed by the magnifying glass lens barrel 1. A magnet can be arranged on the bottom plate one 14 to firmly suck the fixture 12.

[0084] It should be understood that in the development process of any actual implementation manner, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, such development efforts will be a routine work of design, manufacturing, and production.

[0085] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
