For convenience of explanation, be referring to Fig. 2 and Fig. 3, Fig. 2 the utility model fixing seat 100 an embodiment
Schematic diagram, Fig. 3 is the decomposition diagram of fixing seat 100 shown in Fig. 2.As shown in Fig. 2, fixing seat 100 is for fixing optics
Element 10 is simultaneously used to be arranged elastic component 151,153, and optical element 10 includes optical axis 11.Fixing seat 100 include fixing groove 110,
Elastic component fixing groove 130.Fixing groove 110 is for being arranged optical element 10.Fixing groove 110 includes first end 111, second end 113
And abutment face 115.Fixing groove 110 extends to second end 113 by first end 111 and is formed, and first end 111 not with second end 113
Connection.Elastic component fixing groove 130 is extended to the second fixing end 133 by the first fixing end 131 and is formed.Elastic component 151,153 can
It is inserted into elastic component fixing groove 130.Elastic component 151 is including force section 1511 and through linking arm (not shown) and force section 1511
The support portion 1513 being connected, elastic component 153 is including force section 1531 and penetrates linking arm (not shown) and 1531 phase of force section
The support portion 1533 of connection.Support portion 1513,1533 is resisted against the inner surface of elastic component fixing groove 130, to provide force respectively
Portion 1511,1531 towards optical element 10 thrust (not shown) so that optical element 10 is supported on abutment face 115.Fixing groove
110 opening direction and the opening direction of elastic component fixing groove 130 are all not parallel to 11 direction of optical axis, and elastic component 151,
153 and optical element 10 be respectively implanted in flexible fastening slot 130 and fixing groove 110 along the direction for being not parallel to optical axis 11.
When optical element 10 is set in fixing groove 110 and elastic component 151,153 is set to flexible fastening slot 130, bullet
Property part 151,153 the elasticity pushing and pressing optical element 10 of force section 1511,1531, to cause partial optical element 10 to support abutment face
115.In one embodiment, the normal direction of the tangent plane of any point can not be with optical element on the abutment face 115 of fixing groove 110
10 optical axis 11 is vertical.
Therefore, by the setting of fixing groove 110, elastic component fixing groove 130 and elastic component 151,153, can quickly and
Easily optical element 10 is accurately arranged in fixing seat 100.Pass through the force section 1511,1531 of elastic component 151,153
Elasticity pushing and pressing optical element 10, can allow partial optical element 10 to support abutment face 115, and optical element 10 is accurately arranged
In required assembled position, and can to avoid optical element 10 tilt or be displaced the problems such as.
Specifically, when elastic component 151,153 is set in elastic component fixing groove 130, elastic component 151,153 parts are set
It is placed in elastic component fixing groove 130, and is born against by support portion 1513,1533 and consolidated in the first of elastic component fixing groove 130
The inner surface of fixed end 131 and the second fixing end 133, to provide thrust of the force section 1511,1531 towards optical element 10 respectively,
So that optical element 10 supports abutment face 115.
