A device for cutting and pasting paper for students

technical field

The invention relates to the technical field of paper cutting, in particular to a paper cutting and pasting device for students.

Background technique

With the rapid development of education in our country, the learning pressure of primary and secondary school students has also increased. Primary and secondary school students use more test papers and handouts in the learning process, or when they see some good extracurricular reading materials, students will focus on these content. Cut it out and paste it on your own notebook, but the cutting tools currently used by students are generally a knife or a ruler, which is very inconvenient during the cutting process, and can easily cause damage to the test paper or reading material, and cannot be pasted after cutting, Students are required to use double-sided tape or glue for pasting, which is troublesome to operate and affects students' learning efficiency. Moreover, when cutting with scissors, students may injure themselves due to improper operation, which is dangerous. It is very necessary to have a paper cutting and pasting device for students, which is convenient, reasonable in structure and high in use efficiency.
