Technical Field

The application relates to a microscope carries thing device, especially relates to a locating component and microscope.

background

In the process of diagnosing diseases, whether live cells are diseased or not is judged, the conventional means is to adopt a mode of carrying a bearing member to carry out live body puncture to obtain cell tissues to be detected, the bearing member is fixed on an objective table of a microscope through a fixing device, and the cell characteristics are observed through the microscope, so that the conclusion whether the cells are diseased or not is obtained.

The bearing member is in a structure with a large length-thin ratio, the length of the bearing member is more than three times of the diameter, bending deformation is easy to generate in a free state, and the bearing member is more difficult to maintain in a flat state particularly under the condition that cell tissues to be detected are attached to the bearing member. The traditional fixing device applies tension force to two ends of the bearing piece to provide certain tension rigidity for the bearing piece so as to keep the bearing piece straight. In the practical application process, the tension force is difficult to control, and if the tension force is too small, the bearing part is easy to loosen; if the tension force is too large, the bearing part is easy to generate torsional deformation due to uneven stress, and the detection precision of the cell tissue to be detected is further reduced.

Disclosure of Invention

In order to solve one of the above problems, the embodiments of the present application provide a positioning assembly and a microscope.

the embodiment of the first aspect of the present application provides a positioning assembly, configured to fix a carrier; the method comprises the following steps: the positioning assembly includes:

Positioning a substrate; a first bearing structure and a second bearing structure are respectively arranged at two ends of the positioning base body along the length direction and are respectively used for supporting two ends of the bearing piece;

the first fixing structure is arranged on the first bearing structure and used for fixing one end of the bearing piece;

And the second fixing structure is arranged on the second bearing structure and used for fixing the other end of the bearing piece.

Embodiments of the second aspect of the present application provide a microscope comprising: a positioning assembly as described above.

The technical scheme that this application embodiment provided, adopt first bearing structure and second bearing structure to set up the both ends at the location base member respectively, a both ends for supporting carrier, still adopt first fixed knot structure to set up the one end of carrying the thing on first bearing structure and fix, second fixed knot constructs the other end of carrying the thing on second bearing structure and fixes, because first bearing structure and first fixed knot construct the power of carrying the thing and be the carrier axial direction of perpendicular to, second bearing structure and second fixed knot construct the power of carrying the thing and also be the carrier axial direction of perpendicular to, consequently, can not exert torsional force or axial tension to carrying the thing, the problem of adopting the taut mode in both ends to exert torsional force and axial tension to carrying the thing and make to carry the thing and take place torsional deformation easily in traditional scheme has been solved.
