Abstract
Description
Technical Field
[0001] The utility model belongs to the field of criminal technology photography, and particularly relates to a flattening photographing bracket for flexible objects. Background Art
[0002] In the practice of public security trace inspection work, it is common that suspects or parties have come into contact with certain flexible objects (such as plastic wrapping paper, smooth paper, fabric) and left fingerprints. Criminal technology personnel often use the method of evaporating 502 glue at high temperature to reveal the fingerprints. However, after the fingerprints are successfully revealed, due to reasons such as the flexible objects being prone to wrinkling and deformation and the revealed fingerprints being easily damaged, it is difficult to photograph and fix the fingerprints on the flexible objects completely and clearly. There are two traditional solutions: First, flatten the flexible object manually. The disadvantage of this method is that it requires the cooperation of multiple criminal technology personnel, the flattening effect is not ideal, and it is easy to damage the flexible object and the fingerprints left on it during the flattening and photographing processes; Second, purchase professional photographing equipment. The disadvantages are high cost, high training cost, inconvenient use, and it is easy to damage the flexible object and the fingerprints left on it during the flattening and photographing processes. At present, photographing and fixing the fingerprints revealed on flexible objects is still a difficult problem in the practice of public security trace inspection work. Content of the Utility Model

The technical solution designed by the utility model includes a base, a support rod, a fixing frame A and a fixing frame B; the base is provided with a groove, one end of the support rod is fixedly connected to the base through the groove, and the end of the support rod away from the base is integrally connected to the fixing frame A; magnets are arranged at the four vertices of the fixing frame A and the four vertices of the fixing frame B, and the fixing frame B is aligned and attached to one side of the fixing frame A through the magnets for fixing the flexible object; the base, the support rod, the fixing frame A and the fixing frame B are all made of transparent acrylic material.
[0004] Preferably, the fixing frame A is provided with two groups of card slots, the two groups of card slots are in an "L" shape and are respectively arranged on the left and right sides of the other side of the fixing frame A where the fixing frame B is aligned and attached, for the filter to be slidably inserted into the card slots; the two groups of card slots are made of transparent acrylic material.
[0005] Preferably, the magnet is a rubidium magnet made of neodymium iron boron material.
[0006] Preferably, the magnets are embedded in the four vertices of the fixing frame A and the four vertices of the fixing frame B.
