Abstract
The utility model discloses a special magnetic powder brush for extraction of fingerprints and relates to criminal investigation tools. The special magnetic powder brush is composed of a center shaft, a plastic head sleeve, a cylindrical magnet, a lantern ring, a push rod, a spring, a steel wire, a thumb button, a hollow handle, a hose torch light handle, an LED lamp holder, a switching button, a battery, a hose, a circuit board, wires and a circular connector. The special magnetic powder brush has the advantages that the plastic head sleeve has sliding performance and can slide on the center shaft along with pushing force generated by pressing the thumb button to be separated from the cylindrical magnet, so that magnetic powder on the plastic head sleeve falls off because of loss of magnetic force; the thumb is loosened, and the thumb button and the plastic head sleeve can both go back to the original state under the action of spring force, so operation is easy, and a traditional two-hand operating method is changed; the magnetic powder brush and a torch light are closely combined into a whole, and a traditional separated structure is changed, so the special magnetic powder brush is more applicable to actual operation; besides, the direction of the LED lamp holder can change along with changes of the bending direction of the hose, so the special magnetic powder brush is more beneficial to discovery of the fingerprints or palm prints on site.
Description
Technical field
This utility model relates to a kind of criminal investigation instrument, or rather, is that the one dedicated magnetic that takes the fingerprint is whitewashed.
Background technology
In daily site inspection, to on-the-spot shadow of doubt, technician by brush magnetic powder to manifest offender's fingerprint or palmmprint, thereby give a clue, try and produce evidence for the detection of case.The magnetic powder brush that the existing technician of basic unit uses, its head and bar portion are fixed, in bar portion, there is a metal pull bar, a Magnet is fixed in pull bar one end, the other end is handle, after use finishes, and the handle of tractive metal pull bar, the bar portion of Magnet meeting indentation magnetic powder brush, thus make the magnetic powder of head surface absorption lose magnetic force and Automatic-falling.These action need both hands have coordinated, and one holds magnetic powder brush holder support portion, and another pulls the handle of moving metal pull bar.In addition, in the reconnaissance at criminal scene at some night, technician also needs to brush magnetic powder on one side, takes torch on one side, and these appointed conditions or operating procedure are all brought great inconvenience to preliminry basic research.
Summary of the invention
This utility model is mainly to solve prior art existing technical problem, thereby provides the one dedicated magnetic that takes the fingerprint to whitewash.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The one dedicated magnetic that takes the fingerprint is whitewashed, and the described dedicated magnetic that takes the fingerprint is whitewashed by telescopic magnetic powder brush and flexible pipe torch two parts and formed.
Described telescopic magnetic powder brush comprises central shaft, plastics headgear, cylinder-shaped magnet, the collar, push rod, spring, steel wire, thumb button and hollow handle.
