in this embodiment of the application, after the first moving part 201 is connected with the first light guide cylinder 11 through the first positioning screw 202, the second moving part 301 is connected with the second light guide cylinder through the second positioning screw 302, at this time, the gear 402 is located between the first moving part 201 and the second moving part 301, but because one side of the first moving part 201 departing from the second moving part 301 is in a free state, one side of the second moving part 301 departing from the first moving part 201 is also in a free state, in order to ensure that the gear 402 and the first moving part 201, and the second moving part 301 are all engaged, this application is provided with two rack limit posts 501 on the horizontal plate 1011, the two rack limit posts 501 are used for limiting the corresponding first moving part 201, the position of the second moving part 301, so that the first moving part 201 and the second moving part 301 can be engaged with the gear 402.

In some embodiments, in order to limit the moving distance of the first moving part 201 and the second moving part 301, as shown in fig. 3 and in combination with fig. 4, the present application provides a first corner 2011 on the first moving part 201, and at the same time, provides a second corner 3011 on the second moving part 301; when the first moving part 201 or the second moving part 301 moves to a preset position, the rack stopper column 501 abuts against the corresponding first corner 2011 or second corner 3011.

In use, when the first moving part 201 and the second moving part 301 approach each other, if one of the rack bar posts 501 abuts against the corresponding first corner 2011 on the first moving part 201, and the other rack bar post 501 abuts against the corresponding second corner 3011 on the second moving part 301, the first moving part 201 and the second moving part 301 cannot approach each other further.

In some embodiments, in order to facilitate fixing the first positioning screw 202 to the first tooth hole 1101 on the first light guiding tube 11 and, at the same time, facilitate fixing the second positioning screw 302 to the second tooth hole on the second light guiding tube 12, as shown in fig. 2, the first moving assembly 20 in this application further includes a first limit nut 203, and the second moving assembly 30 further includes a second limit nut 303, and one end of the first limit nut 203 and one end of the second limit nut 303 are both closed structures; the first limit nut 203 is connected to one end of the first positioning screw 202 far away from the first light guide tube 11, and is used for driving the first positioning screw 202 to rotate, and the second limit nut 303 is connected to the second positioning screw 302, and is used for driving the second positioning screw 302 to rotate.

Because the one end of first stop nut 203 is closed structure, after driving first stop nut 203 to rotate the preset position through the handle, first stop nut 203 just can not continue to rotate relative first positioning screw 202 again, at this moment, it will drive first positioning screw 202 synchronous rotation to continue to rotate first stop nut 203 again to make first positioning screw 202 fasten in the first tooth hole 1101 that corresponds, because the structure of second stop nut 303 is the same with the structure of first stop nut 203, here again do not describe tiredly.

When the gear 402 is used, the gear module is 0.5, the number of teeth is 10, and according to the diameter, the gear module, the number of teeth, 0.5, 10, 5mm, the indexing circumference, the indexing circle diameter, pi, 5mm, 3.14, 15.700mm, the gear indexing arc length is equal to the rack linear stroke. That is, the rack can be driven to move 15.700mm by one rotation of the 0.5 die gear, so that the circumference corresponding to each 1 degree is 15.7/360 ° -0.043, and the angle corresponding to each 1mm circumference is 1/0.043-22.929, so that when the rotating rod 401 drives the gear 402 to rotate 22.929 °, the corresponding first moving member 201 or second moving member 301 can be driven to move 1 mm; because the first moving part 201 and the second moving part 301 are in a symmetrical relationship, when the rack pitch circle moves for 1mm of circle, the distance between the first light guide cylinder 11 driven by the first moving part 201 and the second light guide cylinder 12 driven by the second moving part 301 is 2 mm;

when the distance between the first light guide tube 11 and the second light guide tube 12 is 11 × 2mm, the moving distance of the first moving member 201 or the second moving member 301 is 11mm, and the rotation angle of the gear 402 is required to be 22.929 × 11 to 252.229 °, and after 22 parts are equally divided, the corresponding angle per scale is 252.229/22 to 11.464 °. The diameter of the pointing circle on the dial 404 is 25mm, according to the arc length formula: the sector arc length is central angle degree pi radius/180 22.929 3.14 (25/2)/180 5.001mm, and the adjustment of the central angle degree is pupil distance 2. From this it follows that: the pupil distance is adjusted to 1mm, namely the arc length on the dial is adjusted to 5.001/2, namely 2.500mm (namely the relationship of 1: 2.500 times), therefore, when the pointer 40111 points to the rotary arc length of 2.500mm, the pupil distance is actually adjusted to 1mm, the relationship of amplifying by 2.500 times is realized, and the multiple can be changed in proportion along with the scaling up of the sizes of the pointer and the dial in the invention, so that the actual pupil distance is more accurate.
