Abstract
The utility model discloses a kind of nucleic acid glue cutter sweep, mainly comprise the handle that two structures are identical and symmetrical, two handles intersect and hinged by fixed pin shaft mutually, the force section that each handle comprises grip part and is fixedly connected with grip part, be symmetrically arranged with blade in the inner side of two force sections, described blade is connected with force section by contiguous block.The force section of contiguous block and handle is one-body molded.The front end of contiguous block has been located at insert pocket, and described blade is connected in insert pocket.The utility model is by the distance between adjustment two handle force section and then the spacing between adjustment two blades, simple to operate, make rubber tapping work rapid and convenient, can ensure that its hand and arm are away from blob of viscose and blade, objectionable impurities is not easily stained with on arm, from ultraviolet injury, ensure that the personal safety of operating personnel, single stage method is cut; Save the time; Blob of viscose can be put into centrifuge tube by rubber cutting apparatus accurately simultaneously, decreases loss and the pollution of blob of viscose.
Description
Technical field
The utility model relates to biological experiment clothing arts, is specifically related to a kind of nucleic acid glue cutter sweep.
Background technology
Agarose gel electrophoresis is a kind of electrophoresis method making supporting dielectric with agarose, and its analysis principle and the main difference of other holder electrophoresis are: it has concurrently " molecular sieve " and the double action of " electrophoresis ".The product of general PCR is all detected by agarose gel electrophoresis, object band needs to reclaim in some cases, the method that we adopt rubber tapping to reclaim usually reclaims object band, and the instrument that rubber tapping is reclaimed generally selects single-edge blade, and the method exists following defect and drawback:
(1) although rubber tapping has protective cover, and arm exposes under ultraviolet light, and blade cuts, and needs to carry out multitool operation, and elapsed time is more, ultraviolet is easily burnt arm;
(2) blade rubber tapping, error comparatively large, cutting process accurately can not cut out beam shapes, cut comparatively large then can impurity more, very little then can not complete recovery object band;
(3) hold blade, easily hurt arm, the agarose containing EB has larger toxicity, incorporates wound, larger to human injury.
(4) blob of viscose of well cutting needs to put into centrifuge tube, operates with blade, more clumsy, and blob of viscose easily drops.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of nucleic acid glue cutter sweep, and this cutter sweep is easy and simple to handle, use double blade, blade space regulates by handle, makes rubber tapping work rapid and convenient, effectively can avoid burn or incised wound operator arm simultaneously.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of nucleic acid glue cutter sweep, mainly comprise the handle that two structures are identical and symmetrical, two handles intersect and hinged by fixed pin shaft mutually, the force section that described each handle comprises grip part and is fixedly connected with grip part, be symmetrically arranged with blade in the inner side of two force sections, described blade is connected with force section by contiguous block.
Further, the force section of described contiguous block and handle is one-body molded.
Further, the front end of described contiguous block has been located at insert pocket, and described blade is connected in insert pocket.
Further, the ellipsoidal cross section of described grip part, the center of grip part has been located at gripping hole.
A kind of nucleic acid glue of the utility model cutter sweep, this device comprise two symmetries handle and by two blades that contiguous block is connected with handle, there is following beneficial effect:
1, blade space regulates by hand, makes rubber tapping work rapid and convenient;
2, control blade by handle to cut nucleic acid glue, make people's hand away from blob of viscose, make arm be not easy to be subject to blade injury, and EB is not easy to be stained with arm, alleviate pollution and injury that people is caused;
3, owing to adopting the adjustable cutting of double blade, make originally to need the process of repeatedly cutting to become single stage method cutting, saved the time, decreased arm and expose the injury caused under ultraviolet light;
4, blob of viscose can only be scooped up translation and pour centrifuge tube into by single blade of the prior art, blob of viscose easily drops, and the double blade arm type rubber cutting apparatus of the application can pick up blob of viscose as tweezers, accurately put into centrifuge tube easily, decrease loss and the pollution of blob of viscose.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural representation of a kind of nucleic acid glue of the utility model cutter sweep.
In figure: 1-handle; 1a-grip part; 1b-force section; 2-fixed pin shaft; 3-blade; 4-contiguous block; 5-insert pocket; 6-grips hole.
Embodiment
As shown in Figure 1, a kind of nucleic acid glue cutter sweep described in the utility model embodiment, mainly comprise the identical and symmetrical handle of two structures 1, two handles 1 mutually intersect and hinged by fixed pin shaft 2, the force section 1b that each handle 1 comprises grip part 1a and is fixedly connected with grip part 1a, blade 3 is symmetrically arranged with in the inner side of two force section 1b, blade 3 is connected with force section 1b by contiguous block 4, contiguous block 41 is one-body molded with the force section 1a of handle 1, be convenient to processing, the bulk strength of cutter sweep can be improved simultaneously.
One preferred embodiment, the front end of contiguous block 4 has been located at insert pocket 5, blade 3 is connected in insert pocket 5, blade 3 and the fixed form of insert pocket 5 can adopt blade 3 and insert pocket 5 with interference fit, or after blade 3 is plugged on insert pocket 5, by fixture as screw or spring pin are fixed, adopt above-mentioned any-mode, blade 3 is convenient to change, and can improve the whole service life of cutter sweep.
Preferably, the ellipsoidal cross section of grip part 1a, the center of grip part 1a has been located at and has gripped hole 6, and convenient operation personnel grip and apply cutting force.
A kind of nucleic acid glue of the utility model cutter sweep, in use, regulate the distance between two handle force sections by hand and then regulate the spacing between two blades, simple to operate, make rubber tapping work rapid and convenient simultaneously, the grip part of the hand-held handle of operator, can ensure that its hand and arm are away from blob of viscose and blade, objectionable impurities is not easily stained with on arm, can be can from ultraviolet injury, ensure that the personal safety of operating personnel, owing to adopting the adjustable cutting of double blade, make originally to need the process of repeatedly cutting to become single stage method cutting, save the time, rubber cutting apparatus can pick up blob of viscose as tweezers simultaneously, accurately put into centrifuge tube easily, decrease loss and the pollution of blob of viscose.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
