Abstract

The utility model belongs to mechanical product which is a special tool adopting the spinning method to sample. The structural feature of the special tool is the integration of a hollow ball knob, a slide bar and a cutter which is inlaid in a copper bush to be placed in a shell having a spring. In the hollow ball knob and the slide-bar, an ejector rod and a thin steel wire are connected and are perpendicular to a fixed plate, and the cutter is caused to extend into a hollow cavity via a plug and a pressing spring. Firstly the special tool eliminates the phenomenon that the finger is sore due to the continuous operation and sampling; the sample can be cut only by slight force; secondly, the cutter position is good; the abuse that the cutter is ruptured due to the fact that the strain is uniform or the direction of the applying force is not vertical to the paper surface is overcome; thirdly, the sample in the cutter is convenient to be taken out.

Description

Microscale sampler

Technical field

The utility model belongs to a kind of engineering goods, adopts the specific purpose tool of spin-on process sampling, carries out the usefulness of check evaluations such as document, seal for the technician of public security department.

Background technology

Existing sampling instrument is to serve as the sampling cutting knife with the stainless steel syringe needle, and the knurled knob head of an about 10-12mm of diameter is installed on syringe needle top, when cutting the sample sample of document with it, with finger control, firmly press down this knob head of rotation entirely, the serial sampling running time one is long, finger is ached, it is hard to exert all one's strength, if wear the gloves operation, easily the syringe needle cutting knife is fractureed again, and be difficult in cutting knife, taking a sample, use very inconvenient.

Summary of the invention

The purpose of this utility model is to overcome outside the deficiency of existing sampling instrument, aims to provide a kind of novel micro sampler.

The purpose of this utility model can realize by following measure

A kind of microscale sampler mainly is made up of hollow handle ball, slide-bar, push rod, copper sheathing, stage clip, housing, spring, cutting knife, finer wire, location-plate.Hollow handle and slide-bar are become one, and by centering location in the copper sheathing, are seated in the housing of spring.In hollow handle ball and slide-bar, push rod links to each other with cutting knife and perpendicular to location-plate, and stretches in the cavity by screw plug, stage clip.Press down when cutting pattern and the rotary handle ball get final product, in cutting knife, take out check sample with push rod, finer wire then.

Advantage of the present utility model and beneficial effect are

1, increased rotation when exerting pressure handle, sampling operation, finger is firmly very light comfortable, has eliminated the phenomenon that former instrument is ached finger fully;

2, increased the guiding and the stabilising arrangement of cutting knife newly, overcome former instrument because of finger firmly with the fracture phenomenon of cutting knife of paper out of plumb;

3, design the mechanism that from the fine aperture of cutting knife, takes out small sample sample, sampling is finished with cutting the once coherent operation of sample, both increased work efficiency, be difficult for losing, obscuring the sample of taking-up again.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail again

A kind of microscale sampler mainly is made up of hollow handle ball 1, slide-bar 3, push rod 4, copper sheathing 5, stage clip 6, housing 7, spring 8, cutting knife 9, finer wire 10, location-plate 11.Hollow handle ball 1 is become one with slide-bar 3, cutting knife 9, and by copper sheathing 5 centerings location, is seated in the housing 7 of spring 8, and location-plate 11 is embedded on the housing 7.In hollow handle ball 1 and slide-bar 3, push rod 4 links to each other with finer wire 10 and perpendicular to location-plate 11, and by screw plug 2, stage clip 6, cutting knife 9 is extend in the cavity 12.

Sample is placed on transparent cavity 12 and location-plate 11 times, and rotation is exerted pressure handle 1, slide-bar 3, cutting knife 9 by copper sheathing 5 centerings location, along housing 7 glide, compression spring 8, make cutting knife 9 cut sample, and set back by spring 8.Press lower push rod 4 compression press springs 6 again, the finer wire 10 that links to each other with push rod 4 is stretched out by the cutting knife bottom, takes out sample, and stage clip 6 sets back push rod 4, finer wire 10, carries out cycling next time.
