Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1-2, the present invention provides a kind of technical scheme: a kind of in the stereomicroscope of control stent length, bag
Including base 1, the side of base 1 upper surface is fixedly connected with first stay tube 2, and the inwall bottom first stay tube 2 is fixing to be connected
Having the first motor 3, the side of the first motor 3 to be fixedly connected with rotating disk 4, the side of rotating disk 4 is fixedly connected with first and fixes axle 5,
The inwall on the first surface and clutch shaft bearing 6 fixing axle 5 is flexibly connected, and the side of the outer wall of clutch shaft bearing 6 and connecting rod 7 is fixed
Connecting, the opposite side of connecting rod 7 is fixedly connected with second and fixes axle 8, and second fixes the surface of axle 8 and the inwall of the second bearing 9
Being flexibly connected, the outer wall of the second bearing 9 is fixedly connected with push rod 10, and the total length of push rod 10 and connecting rod 7 is 15 centimetres, the
A length of 30 centimetres of one stay tube 2, one end of push rod 10 is fixedly connected with the first expansion link 11, the first expansion link 11 another
One end passes first stay tube 2, and the side of the first expansion link 11 is fixed with one end of second stay tube 12 and is connected, by first
Motor 3 and the cooperation of clutch shaft bearing 6, make the second bearing 9 drive push rod 10 to move, thus the first expansion link 11 can move, from
And making the highly automated regulation of stereomicroscope, the inwall width of first stay tube 2 is ten centimetres, the width of the first expansion link 11
Being ten centimetres, the inwall of second stay tube 12 is fixedly connected with the second motor 13, and the surface of the second motor 13 rotating shaft is fixing to be connected
Having projection 14, one end of projection 14 is through turning the opening that the surface of bar 15 is offered, and the width turning the opening that bar 15 surface is offered is same
The diameter of projection 14 adapts, and the one end turning bar 15 is movably connected in the surface of the second motor 13, and turn the other end of bar 15 with
The side of connecting rod 16 is flexibly connected, and the opposite side of connecting rod 16 is connected with fixed plate 17, the opposite side of fixed plate 17 and fore-set
The bottom surface of 18 is fixing to be connected, and the side of fore-set 18 is fixedly connected with the second expansion link 19, by the second motor 13 and projection 14
Coordinate, make to turn bar 15 and connecting rod 16 moves, so that fore-set 18 drives the second expansion link 19 to move, make stereomicroscope and people's
Distance is automatically adjusted, and people use convenient, and first stay tube 2 is identical with second stay tube 12 size, the first expansion link 11
Identical with the second expansion link 19 size, the opposite side of the second expansion link 19 is fixedly connected on through the opposite side of second stay tube 12
The surface of microscope body 20.
Operation principle: when being easy to the stereomicroscope use controlling stent length, by the first motor 3 and clutch shaft bearing
The cooperation of 6, makes the second bearing 9 drive push rod 10 to move, so that the first expansion link 11 is at the internal motion of first stay tube 2,
Thus reach the purpose of regulation height, by the second motor 13 and the cooperation of projection 14, make to turn bar 15 and connecting rod 16 moves, thus
Make fore-set 18 drive the second expansion link 19 at the internal motion of second stay tube 12, thus reach the mesh of regulation and people's distance
's.
