Background technique

In many exams nowadays, it is necessary to write with a water-based pen and at the same time use a pencil to draw cards, and when there are mistakes in the drawn cards, it is necessary to use an eraser to correct them. Candidates who take various types of examinations now need to bring pens, pencils and erasers, and before use, they need to use a pencil sharpener to cut the pencil lead into a rectangle so that it can be painted on the card. It can be seen that the following problems are more prominent in this situation : 1. It is inconvenient to carry a lot of things, and it is easy to lose; 2. It is troublesome and wasteful to cut the general cylindrical pencil lead into a rectangle suitable for the shape of the card during the test; 3. When the card is wrong, the general eraser Due to the larger size it is difficult to wipe and may wipe off other answers.
