Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: a WEB fingerprint information identification device comprises a fingerprint identification card punch 1, wherein a right-angle triangular groove is formed in one side of the upper end of the fingerprint identification card punch 1, and a fingerprint screen 2 is arranged on the inclined surface of the right-angle triangular groove, which is a conventional structure on the existing fingerprint identification card punch and is used for conveniently pressing the fingerprint screen 2 with a finger to punch a card;
a dustproof cover plate 4 is hinged at the upper end of a right-angle groove wall corresponding to the fingerprint screen 2 in the right-angle triangular groove, a spring groove 6 is arranged in the middle of the groove wall, a bending spring 7 is fixed in the spring groove 6, one end of the bending spring 7, far away from the spring groove 6, is fixed in the middle of the lower side of the dustproof cover plate 4, one end of the dustproof cover plate 4, far away from the hinge joint, is provided with a telescopic plate groove 8, a telescopic plate 5 is movably inserted in the telescopic plate groove 8, both ends of one side, located in the telescopic plate groove 8, of the telescopic plate 5 are both connected with a return spring 9, one end, far away from the telescopic plate 5, of the return spring 9 is both fixed on one groove wall of the telescopic plate groove 8, one side, far away from the return spring 9, of the telescopic plate 5 is provided with a clamping groove 10, a silica gel block 11 is clamped in the clamping groove 10, one side, the silica gel block 11 is used for wiping the fingerprint screen 2 when the dustproof cover plate 4 is turned over;
