The invention relates to a handheld
fingerprint acquisition device. The device comprises a main body and a collection device, and further comprises a
protection mechanism and an
electric power auxiliary mechanism. The
protection mechanism comprises a protection cover, a moving block, a connecting rod, a baffle, a
rubber ring and two return assemblies. The
electric power auxiliary mechanism comprises an air conveying
pipe, a power
pipe, a generator, a transmission shaft, fan blades, a dustproof net, a supporting
assembly and an air gathering ring. The return
assembly comprises a guide groove, aguide rod, a spring and a mounting hole, and the supporting
assembly comprises a supporting rod and a mounting bearing. According to the handheld
fingerprint acquisition devicem the collection deviceis covered by the
protection mechanism, under the protection effect of the protection mechanism, the probability that the collection device is abraded is reduced, the recognition precision of the
fingerprint collector is improved, the
electric energy can be generated through the
electric power auxiliary mechanism, then the
electric energy is supplied to the fingerprint collector for use, so thatthe consumption of the fingerprint collector on the external
electric energy is reduced, and the energy-saving performance of the fingerprint collector is improved.
