Connect fixing component 30.Described refers to rotatably relative to the rotation of at least two axis directions, such as the directions H and the directions V, such as to scheme
Shown in 4B, Fig. 4 C；Can also be more rotation axis directions；That is the first end 41 of the link component 40 is along at least two
A first rotary shaft (such as H1 axis, V1 axis, or more direction in H1V1 planes) be rotatably coupled the mobile member 20, should
The second end 42 of link component 40 along at least two second rotary shafts (such as H2 axis, V2 axis, or more side in H2V2 planes
To) it is rotatably coupled the fixing component 30, the direction of the direction of each first rotary shaft and second rotary shaft is one by one
It is corresponding.Preferably, each first rotary shaft intersects at same first rotary middle point, and each second rotary shaft intersects at same second rotation
Turn central point.The rotation of first end 41 and second end 42 can also be end relative to an axis of rotation spherical rotary, first end
41 and the end surface of second end 42 tangentially rotated relative to the spherical surface in an axle center, as shown in Figure 4 A, in this way, mobile member 20 can
Any angle and distance are adjusted in its mobile range relative to fixing component 30, adjustable maximum distance is limited to connect
The length and maximum tilt angle of connecting rod 43 in bar component 40；The axis of rotation can be fixed with position, also with connecting rod structure
Small-scale movement occurs for the turned position of part 40.
Preferably, it can realize that mobile member 20 exists by the combination of multiple link components 40 and/or multiple abutting members 60
In mobile process, remain perpendicular to optical axis direction S (being parallel to HV planes in other words).
The quantity of link component 40 is at least three, and three link components 40 are not on same straight line at this time, according to three
Point determines the principle in face, ensures that mobile member 20 is parallel to plane HV always in moving process.According to the shape of mobile member 20

The intersection point 411,421 of the equal length of line, the first end 41 of each link component 40 and the above-mentioned vertical join line of second end 42 it
Between distance it is also equal, to also forming parallelogram；Link component 40 first end 41 and second end 42 respectively along right
When the first directions rotary shaft H1 answered and the second directions rotary shaft H2 rotate, the first end 41 of two link components 40 it is each
Vertical join line begins between one-to-one 1 second rotary shaft H2 of vertical join line and second end 42 between the first rotary shaft H1
Whole keeping parallelism；When intersection point 411 at the first rotary shaft H1 of multiple link components 40 is not at same straight line, one is constituted
Plane, to which the intersection point 421 at the second rotary shaft H2 also constitutes a plane, to ensure that the first end 41 of link component 40 connects
The bottom surface of mobile member 20 remain parallel with 30 groove of fixing component, 31 bottom surface that second end 42 connects, mobile member 20
Always it is moved in the plane for being parallel to 30 groove of fixing component, 31 bottom surface.Preferably, each first rotary shaft (such as H1 axis, V1
Axis) intersect at same first axis of rotation, each second rotary shaft (such as H2 axis, V2 axis, V1, V2 axis are each parallel to V axis) intersection
In same second axis of rotation, to which the inclined degree in each direction of rotation can be consistent.It can also each rotary shaft not phase
Same axis of rotation is met at, the angle of inclination of each direction of rotation or range can difference at this time.Link component 40
