Abstract

The utility model relates to a strip extractor for hands, feet and skin. One end of a Y-shaped support frame 1 with a handle 4 is fixed with a rubber roller 5 which can roll, and the other end of the Y-shaped support frame 1 is fixed with a rotatable adhesive tape paper reel 8. Since the support frame having a triangular structure is stable, the surface of the rubber roller is smooth, the support frame has elasticity, large contact area, uniform pressure, and gummed paper can be spread on a crease without crinkle and air bubble, the strip extractor of the utility model can increase the speed and raise the quality of extracting the strip of hands, feet and skin, and compared with traditional method, strip extraction via the crease is standard.

Description

Strip maker for hand, foot and skin

This utility model relates to the public security equipment in power tool field, particularly impression instrument for extracting.

In criminal scene is reconnoitred, can extract the important step that impression is Forensic Science work fast, simply, in high quality, its extraction quality directly affects the accuracy of evaluation.For a long time, the hands, foot, the skin stricture of vagina that extract on the object all are to continue to use the traditional method that hands is rolled moulding paper, and this method has many shortcomings in real work: (1). take off the gummed paper difficulty.(2). one man operation's inconvenience.(3). gummed paper difficulty is rolled flatly, is prone to bubble and fold.(4). extraction rate is slow.Above-mentioned shortcoming has reduced hands, foot, the skin stricture of vagina quality extracted, brings certain difficulty to evaluation.And these shortcomings mainly to be physiological characteristics (, pressure inequality uneven as watch face) by human body determined, extract when even referring to fingerprint, palmmprint, barefootprints particularly outstanding.

The purpose of this utility model is to provide a kind of easy, quick, high-quality hands, foot, skin stricture of vagina instrument for extracting.

Technical solution of the present utility model is: hands, foot, skin stricture of vagina extractor.The fixing rotatable rubber rollers of one end of " people " font support of band handle, the other end is fixed rotating adhesive tape paper roll.Axle inserts the inner core of rubber rollers, and two ends are locked on the support by nut.The adhesive tape paper roll is fixed on the sleeve by the gummed paper fast pulley, inserts axle in the sleeve and is locked on the support by nut.

According to technique scheme, earlier the adhesive tape paper roll is fixed on the sleeve with the gummed paper fast pulley, be fixed on the support through the interpolation axle then, aim at the position of being extracted, handle is taken off gummed paper on the other hand on the other hand, take off to adhesive tape and can be pressed in rubber rollers following time, lift the adhesive tape wheel slightly, push hard and get final product.Cut off adhesive tape after the adhesion; Uncover adhesive tape one end during extraction, the other end still sticks on the object about about 1cm, will extract paperboard and send under the adhesive tape, rolls pressure by adhesive tape one end of not uncovering to the other end with rubber rollers, promptly finishes whole operating process.Support adopts " people " font A-frame good stability, and rubber rollers smooth surface, good springiness, contact area is big, pressure is even, can overcome manual shortcoming.This utility model equipment is simple, and is easy to operate, the hands of extraction, foot, skin stricture of vagina quality height, and speed is fast.

Accompanying drawing 1 is this utility model sketch map;

Accompanying drawing 2 is this utility model side view;

Accompanying drawing 3 is this utility model vertical view;

In conjunction with the accompanying drawings, a kind of embodiment of the present utility model is described.Hands, foot, skin stricture of vagina extractor, the fixing rotatable rubber rollers 5 of an end of " people " font support 1 of band handle 4, the other end is fixed rotating adhesive tape paper roll 8; Axle 7 inserts the inner core of rubber rollers 5, and two ends are by nut 6 lockings, and an end of support 1 has the breach 2 of being convenient to installation shaft 7; Adhesive tape paper roll 8 is fixed on the sleeve 10 by gummed paper fast pulley 9, its fixed form is for being threaded, there is the hands of being convenient to turn to remove breach 12 on the gummed paper fast pulley 9, inserts axle in the sleeve 10 and by nut 11 lockings, an end of support 1 has the breach 3 of being convenient to installing sleeve 10 interpolation axles.
