In ring body 0110.
Preferably, have between the outside wall surface of the internal face of the first torus 0110 and the second torus 0210 and be not more than
The unilateral gap width of 1mm.Specifically, the difference between the outside diameter of the internal diameter of the first torus 0110 and the second torus 0210 is not
More than 2mm, the first torus 0110 and the second torus 0210 is set to form clearance fit.On the one hand, the second torus 0210 had been both
The first torus 0110 can be swimmingly rotated on, there is very easily regulative mode；On the other hand, second torus 0210
Adjust interstice coverage to be in ideal range, be more easy to realize accurate adjusting, adjust difficulty and be also greatly lowered.
Further preferably, between the second torus 0210 and first connecting portion 0111 there is unilateral gap width to be not more than
The clearance fit of 0.5mm, further limits the adjustment interstice coverage of the second torus 0210, makes adjusting more accurate.In other words,
Second torus 0210 has clearance fit with first connecting portion 0111, and the internal diameter of first connecting portion 0111 (is under internal thread
Diameter of thread) difference between the outside diameter of the second torus 0210 is not more than 1mm, connects easy to the second torus 0210 in first
The disengaging of socket part 0111 picks and places, while applies axial constraint to the second torus 0210, avoids the second torus 0210 that accident occurs
Slide.
Second connecting portion 0220 can use multiple structural forms, such as all kinds of cylinders, and opening up vertically and the second torus
The through hole of 0210 perforation, to ensure light path therethrough.More preferably, second connecting portion 0220 has annulus column structure and rotatably
It is held in the first annulus end face 0120, second connecting portion 0220 is used to be connected with fuselage and keeps light with the second torus 0210
Road penetrates through.
In other words, 0220 and second torus 0210 of second connecting portion is respectively provided with circular ring structure, is respectively provided with inside the two logical
Hole simultaneously keeps being mutually communicated.When 1000 both ends of optical axis adjustment means difference connection lens and fuselage, the light path of camera lens is through the
Two torus 0210 keep penetrating through with second connecting portion 0220 with fuselage.
Second connecting portion 0220 can use a variety of connection structures, depend primarily upon the structure of the connecting pin of fuselage.More typically
Ground, the type of attachment of second connecting portion 0220 and fuselage includes being threadedly coupled, is clamped and dismountable structure type such as fastens, such as with
Threaded portion or Access Division that the connecting pin of fuselage matches etc..
In an exemplary embodiment, second connecting portion 0220 has external screw thread, is connected corresponding to using internal thread
The fuselage at end.In other words, second connecting portion 0220 protrudes from second one end of torus 0210 away from first connecting portion 0111, shape
Into a boss structure.Meanwhile second connecting portion 0220 protrudes from the first annulus end face 0120 away from first connecting portion 0111 in the lump
One end.Under internal and external threads coordinate, second connecting portion 0220 is connected and fixes with fuselage, so that fuselage and optical axis adjustment means
1000 are connected as one.In another embodiment, second connecting portion 0220 can use internal thread form, corresponding to using outer spiral shell
The fuselage of line connecting pin.
It should be noted that when second connecting portion 0220 has the end face for protruding from the second torus 0210 and forms boss,
The internal diameter of first annulus end face 0120 is more than the outside diameter of second connecting portion 0220.In other words, the first annulus end face 0120 and second
Connecting portion 0220 has clearance fit relationship, inner ring of the second connecting portion 0220 through the first annulus end face 0120 and stretch out in second
Outside one end of torus 0210.Meanwhile second connecting portion 0220 is rotatably held on the first annulus end face 0120, make
Two components 0200 can easily rotate or mobile adjustment.
Second torus 0210 can use a variety of connection structures, foregoing boss, round platform with second connecting portion 0220
Structure etc..Preferably, the second torus 0210 has the second annulus end face 0230 close to one end of second connecting portion 0220, and second
The outer ring of annulus end face 0230 is connected with the internal face of the second torus 0210, and the inner ring of the second annulus end face 0230 and second connects
The inside of socket part 0220 connects and keeps light path therethrough.Second torus 0210 can be separately set with the second annulus end face 0230,
In this embodiment, it is preferred that the two is integrated connection structure.
Specifically, the second annulus end face 0230 has cirque structure, and it is remote that its outer ring is embedded in the second torus 0210
One end end of first connecting portion 0111 and with 0210 integrally connected of the second torus.The inner ring of second annulus end face 0230 and
The inside of two connecting portions 0220 keeps perforation,
In other words, when first component 0100 and second component 0200 assemble in place, the first torus 0110, the second annulus
The through hole that body 0210 each has with second connecting portion 0220 integrally penetrates through, and forms an optical axis hole penetrated through vertically.It is preferred that
Second annulus end face 0230 has coaxial relation with second connecting portion 0220, and optical axis hole is in centre, makes paths more
It is straight.
Preferably, the axial dimension after the first torus 0110 removal first connecting portion 0111 is more than the second torus 0210
Axial dimension.In other words, the second torus 0210 and the first torus 0110 have along between the axial direction of the first torus 0110
Gap, has along the axial adjusting space of the first torus 0110, optical axis adjustment means 1000 is had axial direction and radiai adjustment concurrently
Power.
In application, second component 0200 is sheathed in first component 0100.First connecting portion 0111 is connected with camera lens, and second
Torus 0210 is sheathed in the first torus 0110, and second connecting portion 0220 is stretched through the inner ring of the first annulus end face 0120
