Specifically, the lens fixing apparatus further include: the first spring tip 60 carries mirror body 10 for spring 50 to be fixed on
On.
Shown in Figure 2, the first side for carrying mirror body 10 is additionally provided with groove 103, and the second side for carrying mirror body 10 is equipped with circle
Hole 104, circular hole 104 are connected with groove 103；Second side is a side adjacent with first side.It is shown in Figure 3,
One end of spring 50 is arranged in groove 103, and the first spring tip 60 is arranged in circular hole 104；Due to circular hole 104 and groove 103
It is connected, one end of spring 50 can be fixed in groove 103 by the first spring tip 60.Specifically, needing fixed spring 50
One end when, by one end of spring 50 sink to carry 10 surface of mirror body groove 103 in, the first spring tip 50 is inserted into later
In the circular hole 104 for carrying 10 second side of mirror body.Wherein, spring 50, the first spring tip 60 are one-to-one, i.e. the two number
It measures identical.Illustrate by taking eight springs 50 and eight first spring tips 60 as an example in Fig. 2 and Fig. 3.It is needed in mirror body 10 correspondingly, carrying
Open up eight grooves 103 and eight circular holes 104.
In addition, the fixation of the other end in order to realize spring 50, shown in Figure 4, eyeglass provided in this embodiment is fixed
Device further include: the second spring tip 70.Wherein, the inner wall that cavity 201 is provided with the second light hole 202 is also provided with through-hole, spring 50
The other end may pass through the through-hole；The outer surface of shell 20 is arranged in the second spring tip 70, for being secured across the bullet of through-hole
The other end of spring 50.
Optionally, as shown in figure 4, through-hole close to shell 20 outer surface one end be strip groove, strip groove use
In the fixed setting second spring tip 70.
Fig. 4 in the present embodiment is to carry the installation of mirror body 10 to the schematic diagram after the cavity 201 of shell 20.Specifically, carrying mirror
After body 10 fixes spring 50 according to mode shown in Fig. 3, mirror body 10 will be carried and be pushed into from 201 opening of cavity of shell 20, outside
103 position of groove of through-hole (i.e. the through-hole that the inner wall of the second light hole 202 opens up) and load mirror body 10 on shell 20 corresponds,
Then the other end of spring 50 can be fallen into the through-hole of shell 20；It, can be by bullet by stretching the spring 50 in 20 through-hole of shell
Spring 50 is stretched to the outer surface of shell 20, passes through the circular hole of 50 other end of spring with the second spring tip 70 later.In addition, also
The second spring tip 70 can be fixed in the strip groove of case surface.Pass through spring 50 and the two kind of spring tip (i.e. first spring
The tip 60 and the second spring tip 70) realize the connection for carrying mirror body 10 and shell 20.It carries mirror body 10 and shell 20 passes through the drawing of spring 50
Power realizes connection, and subsequent adjustment is facilitated to carry position of the mirror body 10 in cavity pocket of outer cover 201.
In addition, load mirror body 10 will be carried to after in shell 20, capping 30 can closed cavity 201 opening.Such as Fig. 4 institute
Show, the upper surface of shell 20 is additionally provided with threaded hole (illustrating by taking four threaded holes as an example in Fig. 4), passes through holding screw 301
Capping 30 is fixed on to the upper surface of shell 20, referring specifically to shown in Fig. 5.
In addition, the eyeglass in existing lens fixing apparatus can only axially be translated along one or two kinds of, such as left and right
Translation and upper and lower translation cannot achieve the translation of three axis, that is, can not achieve anterior-posterior translation.Meanwhile existing lens fixing apparatus is difficult
Adjust the angle direction of eyeglass.It further include the first adjusting bolt 80 the present embodiment provides lens fixing apparatus.Referring to figs. 5 and 6
It is shown.First outer surface of shell 20 is provided with the first threaded hole of perforation to cavity, and the first outer surface is to be provided with the second light hole
Outer surface；First length for adjusting bolt 80 is greater than the length of the first threaded hole, and first, which adjusts bolt 80, screws in the first screw thread
In hole, for adjusting the distance between the cavity inner wall for carrying mirror body 10 and shell 20.
In the present embodiment, the first adjusting bolt 80 has run through the first threaded hole, and the tail end of the first adjusting bolt 80 touches
Mirror body 10 is carried, by the cavity inner wall for being screwed into the adjustable load mirror body 10 and shell 20 of depth for adjusting the first adjusting bolt 80
The distance between.Specifically, first is adjusted between adjustable load mirror body 10 and the cavity inner wall of shell 20 of bolt 80 in optical path
Distance on direction, i.e. longitudinal separation in Fig. 5.Optionally, the first adjusting bolt 80 can have multiple, be with four in Fig. 5
Example explanation.When the first adjusting bolt 80 has multiple, can preferably be controlled by the first adjusting bolt 80 for adjusting all simultaneously
System carries the distance between mirror body 10 and shell 20；It is enclosed in addition, adjusting bolt 80 by adjusting part first and load mirror body may be implemented
It is rotated around some axis, so as to adjust the angle direction of eyeglass.For example, four first adjust two of one side in bolt 80
A first to adjust bolt 80 motionless, two first adjusting bolts 80 of synchronous rotary another side, it can be achieved that eyeglass along in plane
Two vertical axises (i.e. the former two first axis adjusted where bolts 80) forward and reverse rotation.
Optionally, which further includes the second adjusting bolt 90.Referring to shown in Fig. 6 and Fig. 7, the of shell 20
Two outer surfaces or capping 30 are provided with the second threaded holes of perforation to cavity, and the second outer surface is and the appearance that is provided with the second light hole
Other adjacent outer surfaces of face；Second length for adjusting bolt 90 is greater than the length of the second threaded hole, and second adjusts bolt 90
