One end of power column is slidably matched with the helicla flute, and when the worm screw rotates, one end of the rotation force column is along the spiral shell
Spin slot slides；Eyepiece mount, the other end of the rotation force column are fixedly connected with the eyepiece mount.
In this way, the worm screw is slidably matched by helicla flute and the rotation force column, so that when the worm screw rotates,
The rotation force column moves in the horizontal plane along helicla flute, and then drives the eyepiece mount to move in the horizontal plane, passes through
Rotary worm, realizes that interpupillary distance is adjusted.
In one of the embodiments, the helicla flute includes the first helicla flute and the second helicla flute, and described first is spiral
Groove and the second helicla flute mirror symmetry, it is described rotation force column include respectively with first helicla flute, the second helicla flute
The the first rotation force column and the second rotation force column being slidably matched.
Further, flex point is not present to be opened up along smooth curve in the helicla flute on the curve.
Preferably, the cross section of the helicla flute is arc-shaped, the rotation force column being slidably matched with the helicla flute
One end it is spherical in shape.
Further, the spherical radius is less than the radius of the arc.
In one of the embodiments, the both ends of the worm screw are respectively equipped with knob.
In one of the embodiments, the rotation force column and the eyepiece mount are integrally formed.
The application also provides a kind of microscope, including above-mentioned interpupillary distance adjusting part.

Embodiment
Below in conjunction with attached drawing, the technical characteristics of the utility model and advantage are clearly and completely described, it is clear that institute
The embodiment of description is only the section Example of the utility model, rather than whole embodiments.
It should be noted that when element is referred to as " being fixed on " another element, it can be directly on another element
Or there may also be element placed in the middle.All connection/the connecting relations arrived involved in text, not singly refer to component and directly connect,
And refer to can be according to specific implementation situation, by adding or reducing connection annex, to form more preferably connection structure.
Please refer to Fig.1 shown in~3, a kind of interpupillary distance adjusting part 10, including：
Worm screw 110, worm screw 110 are equipped with helicla flute, including the first helicla flute 111 and the second helicla flute 112, and first is spiral
111 and second helicla flute of groove, 112 mirror symmetry；
Force column 120 is rotated, including the first rotation force column 121 and second rotates force column 122, the first rotation force column
121 one end is slidably matched with the first helicla flute 111, and one end of the second rotation force column 122 is slided with the second helicla flute 112 matches somebody with somebody
Close, when worm screw 110 rotates, the first rotation force column 111 and second rotates one end of force column 112 respectively along the first helicla flute
111 and second helicla flute 112 slide；
The eyepiece mount 130 of two mirror symmetries, the first rotation force column 121 and second rotate the other end of force column 122
It is fixedly connected respectively with two eyepiece mounts 130.
In this way, the worm screw is slidably matched by helicla flute and the rotation force column, so that when the worm screw rotates,
The rotation force column moves in the horizontal plane along helicla flute, and then drives the eyepiece mount to move in the horizontal plane, passes through
Rotary worm, realizes that interpupillary distance is adjusted.
In one of the embodiments, rotation force column is integrally formed with eyepiece mount.It is appreciated that rotation force column with
