Detailed Description

The utility model will be further elucidated with reference to the drawings and the embodiments, which are exemplary only and do not limit the scope of the utility model.

As shown in fig. 1-5, a child safety knife comprises a knife body 1 and a knife handle 2; the blade body 1 is similar to a triangular shape as a whole; the thickness D of the bottom part 101 of the knife body is 0.5mm-0.9mm, and the thickness of the knife body 1 is gradually increased from bottom to top; the bottom 101 of the knife body is wavy; the knife body 1 is made of metal; the knife handle 2 is fixedly connected with the rear end of the knife body 1. According to the utility model, the thickness D of the bottom surface 101 of the knife body is set to be 0.5-0.9 mm (the thickness of a normal knife edge in the prior art is far smaller than the value), so that the bottom 101 of the knife body cannot form a sharp knife edge, the knife body 1 can be used for cutting articles, meanwhile, the skin of children and other people can be prevented from being cut when the knife body is used, and the safety is improved; the thickness of the knife body 1 gradually increases from bottom to top, so that the rigidity of the knife body 1 can be improved to a certain extent, and the service life of the knife body 1 is prolonged; the bottom 101 of the knife body is wavy, so that the knife body 1 can be cut more easily when cutting articles, for example, children can use the knife to cut fruits or biscuits and the like, and only need to move the knife back and forth continuously during cutting, and certainly, the knife can also be cut vertically; the cutter body 1 made of metal can further prolong the service life of the cutter body 1, and the cutter body 1 is not easy to break.
