The configuration of 164a is similar with model of action, repeats no more in this.The first adjustment element 364 of the present embodiment
Being from the first different places adjusting element 164, the first rotating part 364b adjusting element 364 is star
Type rather than discoid.First adjusts element 364 is used for along first axle A1 " it is screw-locked at support body (not shown),
Rotating part 364b has orthogonal first end face E1 " and side S ", the first end face E1 " it is perpendicular to
First axle A1 " and side S " be not orthogonal to first axle A1 ".Side S " drive for stress
One adjusts element 364 along first axle A1 " rotate.But, the side S ' in above-mentioned Fig. 5 and Fig. 6
In side S " can also have concave convex texture further, for the convenient force of user.
In sum, embodiments of the invention at least have one of them advantage following, the present invention's
In above-described embodiment, first adjusts element is screw-locked at optical base along first axle, and first adjusts element
Rotate not by the first end face stress being perpendicular to first axle, but by being not orthogonal to first
The lateral forces of axis and rotate.Accordingly, other component at scialyscope adjusts unit too close to first
In the case of first end face of part, the first operation adjusting element will not be therefore and inconvenient, uses
Person can force in the side of the first adjustment element and drive the first adjustment element, in order to unit uniform to light
Part is adjusted, and so reaches to improve production efficiency, simplify manufacturing process and improve the effects such as yield.
Additionally, in the above embodiment of the present invention, the external diameter of the first the first end face adjusting element is designed as
Adjust the external diameter of the second end face of element more than second, make the side of the first adjustment element adjust with first
The pivot center (the most above-mentioned first axle) of element has bigger distance, when allowing user force in side
Sufficiently large moment can be produced to drive the first adjustment element to rotate smoothly.
The foregoing is only presently preferred embodiments of the present invention, it is impossible to limit what the present invention implemented with this
Scope, the most all simple equivalence changes made according to the claims in the present invention and summary of the invention and modification,
The most still remain within the scope of the patent.It addition, any embodiment of the present invention or claim
