Problems solved by technology

At present, there are mainly two types of safety scissors designed for children: one is plastic safety scissors, which are made of hard plastic and can prevent children from being injured, but they are not sharp enough and children's strength is relatively small. Safety scissors cannot be used to cut hard cardboard; the other is to blunt or encapsulate the tip of the scissors to prevent children from being stabbed by the tip of the scissors, but the opening angle of the two blades of this kind of scissors is relatively large. There is a problem that it is easy to cut children's fingers

Abstract

The invention belongs to the technical field of study articles and discloses a safe craft scissor. The safe craft scissor comprises two shear blades and two telescopic handles. One end of shear blades are scissor tips and the other end are scissor tails. The middle of the shear blades is provided with a main hinging hole. The inner edge of each scissor tip is provided with a cutting edge and the outer edge of each scissor tip is provided with a first assistant hinging hole. Each scissor tail is provided with a second assistant hinging hole. Two shear blades are mutually hinged through the main hinging hole. One end of each telescopic handle is mutually hinged with the first assistant hinging hole on the two shear blades correspondingly. The other end of each telescopic handles is mutually hinged with the second assistant hinging hole on the two shear blades correspondingly. The safe craft scissor has a high shear ability, a rigid paper can be cut by kids with the safe craft scissor, the expandable angle of the two scissor tips is constrained by the telescopic handles, the fact that fingers of the kids stretch between the cutting edges of the two scissor tips can be prevented, and the injury of cutting fingers of kids is avoided.

Description

technical field [0001] The invention belongs to the technical field of school supplies, and in particular relates to safety craft scissors. Background technique [0002] Paper-cutting can exercise children's imagination and hands-on ability very well, but traditional scissors have sharp scissor blades and scissor tips, which are relatively dangerous and not suitable for children to use. At present, there are mainly two types of safety scissors designed for children: one is plastic safety scissors, which are made of hard plastic and can prevent children from being injured, but they are not sharp enough and children's strength is relatively small. Safety scissors cannot be used to cut hard cardboard; the other is to blunt or encapsulate the tip of the scissors to prevent children from being stabbed by the tip of the scissors, but the opening angle of the two blades of this kind of scissors is relatively large. There is a problem that children's fingers are easily cut. Conte...
