Description
Affiliated technical field
The utility model belongs to a kind of brush of fingerprint on the article that shows and shows instrument, is a kind of fingerprint hairbrush particularly.
Background technology
In the prior art, the scout normally collects evidence by taking the fingerprint.The instrument that often uses when at present, the scout takes the fingerprint is the fingerprint hairbrush.This fingerprint hairbrush includes: the hairbrush of storage bean sheet jelly capsule, brush body and lower end thereof.During use, extruding storage bean sheet jelly capsule, fingerprint powder wherein (copper powder or aluminium powder) can spray, again with the light brush finger line of hairbrush surface.The deficiency of its existence is: the discharge rate of uncontrollable fingerprint powder, and fingerprint powder amount is too much, can stick with paste from the teeth outwards, destroys fingerprint; Fingerprint powder amount is very few, can influence brush and show quality.In addition, leather bag dusts and comes backwash with hand, causes dust from flying easily; And the scope that brush shows is little, and efficient is low.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved fingerprint hairbrush is provided, and it is got the powder amount and can control, and it is big that brush shows area, has improved brush and has shown quality and efficient.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: shell, storage powder box, hairbrush transfer roller, it is characterized in that: the storage powder box is fixed in the shell, the lower port place activity of storage powder box is connected with Lou powder roll shaft, the activity of hairbrush transfer roller is connected in the below of leaking the powder roll shaft, and the bottom of hairbrush transfer roller is exposed at the shell lower port; Be provided with motor and battery in the enclosure, be provided with cell switch outward, motor is connected with the hairbrush transfer roller with leakage powder roll shaft.
The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, open cell switch, motor rotates, and is being with leakage powder roll shaft and hairbrush transfer roller to rotate thereupon.Leaking the powder roll shaft can slowly drain to the fingerprint powder in the storage powder box on the hairbrush transfer roller of below, and the hairbrush transfer roller of rotation is pressed close to fingerprint and brushed apparent, more convenient laborsaving.Most of hairbrush is wrapped up by shell, and skyborne the flying upward of fingerprint powder is restricted, and has reduced the harm of powder to human body to greatest extent.The size of leaking the powder amount is come surely by leaking the powder roll shaft, the leakage powder amount after the setting obtains just right control, and it is too much or very few to have overcome the amount that human factor causes, and has guaranteed brush produce effects fruit.Owing to adopt hairbrush transfer roller brush to show, increase brush and shown area, brush shows once just can successfully manifest fingerprint, has improved the brush obvious effective rate greatly.
