The left installation cover 2 and the right installation cover 3 are assembled into a complete rectangular structure. A connecting plate 7 is glued inside the installation box 1. A hinge is welded on the side of the connecting plate 7 away from the installation box 1. The connecting plate 7 is connected to the vision corrector 4 through the hinge. The vision corrector 4 rotates through the hinge. Support components 5 are provided on both sides of the installation box 1 to support The component 5 includes a support column 501 and a tightening nut 503. The side of the tightening nut 503 is welded to the side of the installation box 1. A rotating plate 504 is provided on the other side of the tightening nut 503. A through hole is opened on the surface of the rotating plate 504, and the size of the through hole is the same as the size of the threaded hole of the tightening nut 503. The bottom of the rotating plate 504 is welded to the top of the support column 501. A tightening bolt 502 is provided on the side of the rotating plate 504 away from the tightening nut 503. The tightening bolt 502 passes through the surface of the rotating plate 504. The through hole acts on the tightening nut 503, and the rotating plate 504 is fixed by tightening the bolt 502 and the tightening nut 503, so as to fix the support column 501. A thread groove is opened inside the support column 501, and the support column 501 is connected with the screw 505 through the thread groove. The end of the screw 505 away from the support column 501 is welded with a support plate 506. The screw 505 rotates in the thread groove inside the support column 501 to adjust the height of the device. The number of support components 5 is four. And the four support components 5 are symmetrically distributed on both sides of the installation box 1. In the initial state, the four support components 5 and the installation box 1 are on the same horizontal plane. When the support components 5 are needed to support the device, the tightening bolts 502 are loosened, and then the rotating plate 504 is rotated at an angle. The rotation angle of the rotating plate 504 is 360 degrees, so the rotating plate 504 can rotate forward and reverse. When the support column 501 is rotated to be perpendicular to the installation box 1, the tightening bolts 502 are tightened to fix the support column 501;

[0021] A limiting assembly 6 is provided on the side of the vision corrector 4, and the limiting assembly 6 includes a first telescopic rod 601 and a second telescopic rod 602, the second telescopic rod 602 is sleeved inside the first telescopic rod 601, a first base plate 603 is welded to the end of the first telescopic rod 601 away from the second telescopic rod 602, the first base plate 603 is adhered to the surface of the installation box 1, a second base plate 604 is welded to the end of the second telescopic rod 602 away from the first telescopic rod 601, and the second base plate 604 is adhered to the side of the vision corrector 4, a fixing ring 606 is welded to the end of the first telescopic rod 601 away from the first base plate 603, one end of the fixing ring 606 is a circular ring, and two arc plates are connected to one end of the circular ring, and through holes are opened on the top of the two arc plates, and a plurality of limiting holes 605 are opened on the surface of the second telescopic rod 602, and the limiting holes 605 penetrate the surface of the second telescopic rod 602, and the fixing ring 606 is threadedly connected with the limiting bolt 607 through the through hole, and is passed between the vision corrector 4 and the connecting plate 7.

When the vision corrector 4 rotates, the second telescopic rod 602 slides inside the first telescopic rod 601. When the vision corrector 4 is adjusted to a suitable angle, the limit bolt 607 is tightened. The limit bolt 607 passes through the limit hole 605 on the surface of the second telescopic rod 602 through the through hole of the fixing ring 606, and finally passes through the pupil of another fixing ring 606 to fix the position of the second telescopic rod 602 to prevent the adjusted angle of the vision corrector 4 from changing. When the angle is adjusted to stretch the second telescopic rod 602 from the inside of the first telescopic rod 601, the longest stretching distance is not greater than the total length of the first telescopic rod 601 plus the second telescopic rod 602. When the angle is adjusted to shrink the second telescopic rod 602 toward the inside of the first telescopic rod 601, the shortest shrinking distance is not less than the length of the first telescopic rod 601.

[0022] Working principle: When in use, the utility model achieves the purpose of vision correction by using the support component 5 to adjust the height of the device and the limit component 6 to adjust the angle of the vision corrector 4. First, open the left installation cover 2 and the right installation cover 3, and then adjust the four support components 5 separately. First, loosen the tightening bolt 502, and then rotate the rotating plate 504. When the rotating plate 504 rotates to be perpendicular to the installation box 1, tighten the tightening bolt 502. When the tightening bolt 502 is completely screwed into the tightening nut 503, the rotating plate 504 is fixed, and then the support column 501 is fixed. After the four support columns 501 are fixed, adjust the height according to the user's requirements. First, manually screw the screw 505 out of the support column 501. When the exposed part of the screw 505 becomes more and more, it means that the height of the device is higher. When the required height is reached, stop screwing the screw 505, and then put the device through the support plate 506. Place it on the table, and then the height of the device is adjusted. Then adjust the angle of the vision corrector 4. First, loosen the limit bolt 607 to disengage it from the limit hole 605 on the surface of the second telescopic rod 602, and then rotate the vision corrector 4. Because the vision corrector 4 is rotatably connected to the connecting plate 7 through a hinge, the vision corrector 4 can rotate around the hinge on the connecting plate 7. After the vision corrector 4 is rotated to a good angle, tighten the limit bolt 607. After the limit bolt 607 passes through the limit hole 605, it passes through the through hole on the surface of the fixing ring 606 and is then locked. At this time, the first telescopic rod 601, the fixing ring 606 and the second telescopic rod 602 support and limit the vision corrector 4. At this time, the angle of the vision corrector 4 is adjusted.
