Abstract

The invention relates to an automatic card painting pen. The automatic card painting pen mainly solves the problems that when an existing card painting pen is used for painting an answer sheet, repeated painting is needed, the car painting speed is low, and painting marks are irregular. The automatic card painting pen is characterized in that a lead core mechanism swing sleeve (3) is arranged inside a main shell (1), a lead core mechanism inner sleeve (6) is arranged in the lead core mechanism swing sleeve (3), and a lead core (12) with a rectangular cross section is arranged inside the lead core mechanism inner sleeve (6). The automatic card painting pen is high in sheet painting speed, clear and standard painting marks can be left at the specific position like stamping, and continuous and automatic lead supplementing can be achieved.

Description

technical field [0001] The invention relates to a stationery product, in particular to an automatic card-painting pen. Background technique [0002] In the current senior high school entrance examination, college entrance examination and other various examinations, most of the multiple-choice questions use the way of painting answer sheets to facilitate scoring by computer, improve the speed of marking papers, and reduce the interference of human factors. At present, the scribbling tools used by candidates are roughly divided into two types: one is to cut the 2B pencil lead into a rectangular cross-section as a scribbling tool; the other is to buy a finished mechanical pencil with a rectangular lead cross-section as a Scribble tool. However, the two tools are basically used in the same way in the process of use. During the test, in order to meet the requirements of the graffiti standard, to prevent the blackness of the graffiti card from being insufficient and to prevent th...
