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 to 5, the present invention provides a technical solution: the utility model provides a pen-type scanner, which comprises a housing 4, inlay in display screen 1 on shell 4 surface, the basal surface of shell 4 is inlayed and is had scanning screen 8, the surface that the both sides of display screen 1 are located shell 4 inlays and has operation button 2, the surface that one side of operation button 2 is located shell 4 inlays and has power button 3, only need align the position department that needs the scanning with scanning screen 8 on shell 4 basal surface, then press power button 3, operation button 2 can begin to operate, and scanning screen 8, display screen 1, power button 3 are prior art, do not do too much here and describe.

The side wall of the shell 4 is fixedly connected with an operating ring 5, the part of the operating ring 5 is positioned outside the shell 4, the surface of the operating ring 5 is uniformly provided with a plurality of positioning teeth 13, the inside of the shell 4 is provided with an adjusting gear 9 matched with the operating ring 5, the adjusting gear 9 and the operating ring 5 are at the same height, the operating ring 5 can be driven to rotate by rotating the operating ring 5 positioned outside the shell 4, the operating ring 5 is matched with the adjusting gear 9 through the positioning teeth 13 on the outer wall of the operating ring 5, so as to drive the adjusting gear 9 to rotate, the inside of the adjusting gear 9 is rotatably connected with a threaded rod 10, the adjusting gear 9 and the threaded rod 10 are coaxial centers, the inner wall of the adjusting gear 9 is provided with an inner thread 11 matched with the threaded rod 10, the positioning teeth 13 are matched with the teeth on the outer wall of the adjusting gear 9, when the adjusting gear 9 rotates, the inner thread 11 and the threaded rod 10 on, so that the threaded rod 10 is threadedly rotated by the adjusting gear 9 and the internal thread 11 to achieve up-and-down displacement.

Threaded rod 10's bottom is equipped with slide mechanism, slide mechanism includes regulating plate 12, regulating plate 12 is located in the middle of threaded rod 10's the bottom, regulating plate 12's bottom is equipped with a plurality of regulating wheels 7, shell 4's bottom surface is seted up and is used with regulating plate 12 cooperation and accomodate groove 6, the cross section of accomodating groove 6 is circular, and the shape size of accomodating groove 6 is unanimous with regulating plate 12's shape size, the two clearance fit uses, regulating plate 12 accessible is accomodate groove 6 and is accomodate to shell 4's inside, when shell 4, when scanning screen 8 uses, slide regulating wheel 7 to shell 4's bottom when outside, can make regulating wheel 7 and scanning paper laminating, the frictional force of paper has been reduced.
