Description
Technical field
The present invention relates to biological material extractor fields, and in particular to a kind of split type roller biological material extractor.
Background technology
Extraction now for biological material mostly uses the viscous method taken, that is, passes through colloid and the object for leaving biological material
Contacted, the sample on object be sticked on extractor, after colloid is detached in laboratory, sample on colloid is examined
It surveys.
Traditional extractor is mostly to dip in subtype structure, i.e., is integrally stored in carton after one layer of colloid being sticked at handle bottom end
In, when use, opens carton, throws off colloid protective film and can be used.The design structure is using more convenient, but there is some
It is insufficient：1, conventional extractor need to be integrally placed in carton, and size and the extractor size of carton mutually restrict, and when extracting, some are recessed
When falling into the biological material in object, extractor is limited by length and can not be played a role；2, conventional extractor is packaged as papery,
It is easy to happen deformation, the seal of box body is poor, not strong to extractor protectiveness in box, and pollution, which easily occurs, leads to serious consequence；
3, conventional extractor colloid part and handle portion distance are closer, and when use is also easy to cause pollution；4, colloid part significant surface
Product is influenced by structure, it is difficult to be increased colloid in smaller volume and be actually used area；5, conventional extractor material waste is big, makes
It can not be reused with primary rear packing box, extractor etc., also easily be polluted the environment while enhancing use cost.
Invention content
In order to solve the above technical problems, the present invention provides a kind of split type roller biological material extractor, it can be by roller
It is separated from extraction handle, it is easy to use, it is simple in structure.

A kind of split type roller biological material extractor, including extraction handle and storage box, the extraction handle includes outside handle
Shell, clamping head, motion bar, roller and multiple into system, it is described it is multiple into system include spring, clearance fit piece and multiple into piece, it is described
Motion bar is mounted in handle casing, and both ends are exposed independent from outside handle casing, the clearance fit piece altogether there are two, be in hollow
Circle, and being installed between motion bar and handle casing, and being fixed together with motion bar, one is located at upper end, and one
It is a to be located at lower end, it is described it is multiple into piece and clamping head be in fall " Qian " shape, and the multiple length into piece is respectively less than clamping head with width, it is multiple
Be positioned in clamping head into piece, the clamping head and it is multiple into piece at the same position of upper end there are through-hole, on the clamping head
The lower end with handle casing is held to be fixed together, the motion bar lower end passes through clamping head and the multiple through-hole on piece, and
It is fixed with nut in end, the spring pocket is located on motion bar between the clearance fit piece and clamping head of lower end, described
Hollow circular gasket is additionally provided between clamping head and spring, the clamping head bottom end is additionally provided with locking system, the roller
It is mounted on clamping head by the way that locking system is detachable.
Further, the roller is wrapped with rubber layer, and the rubber layer surface is also enclosed with colloid layer.
Further, the storage box includes box body and box cover, and there are two parallel racks for the interior setting of the box body, and
Two racks are in top there are groove, in being respectively arranged with card column with rack corresponding position in the box cover.
Further, the locking system includes identical two parts, is respectively and fixedly installed to down " Qian " shape clamping head
Two bottom ends, every part locking system include two identical spring leafs, the equal one end of two spring leafs and clamping head
It is fixed together, other end elasticity separable-closed type is close together, and there are holding holes among two spring leafs.
Further, the motion bar upper end is additionally provided with press section.
The beneficial effects of the invention are as follows：1, roller is fixedly mounted on by the way that locking system is detachable on clamping head, extraction
Roller can be removed from clamping head, be positioned in storage box after biological material, and passes through the rack and card column in storage box
It fixes, protectiveness is stronger, it is entirely avoided the biological material on roller is contaminated；2, pressing for motion bar upper end need to only be pressed
Splenium can remove roller, be touched without hand, convenient and efficient and pollution-free；3, storage box and extraction handle repeat and make
With use cost being greatly saved, and meet environmental requirement.
