Abstract

The invention discloses a safe knife. The safe knife comprises a blade (1) and a protection shell located outside the blade (1). A blade opening is formed in the middle of the protection shell. The blade is located in the blade opening. A notch (103) extending towards the interior of the blade (1) from the upper edge of the blade (1) is arranged on the blade (1). A protection tile (7) and a torsion spring (5) are arranged at the top of the blade opening. The protection tile (7) is located above the notch (103). The two ends of the torsion spring (5) are connected to the protection tile (7) andthe protection shell correspondingly. According to the safe knife, medical packages and hoses connected with syringe needles on the medical field can be subjected to faster cutting operation, harm tothe body is low, and the safe knife can be safely used in the environment that patients in psychiatric wards and the like gain knives and great harm can be generated.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a safety cutting tool. Background technique [0002] In daily life, people are often accidentally stabbed by scissors. On special occasions such as mental illness wards and elementary schools, scissors and other knives are considered dangerous items and are often kept in places where mental patients or elementary school students are not easily accessible. Locally, especially in psychiatric wards, scissors are kept in isolation. Even so, scissors are necessary when cutting medical items such as infusion tubes, and it is a cumbersome thing to take the scissors out of locked drawers and other safe places for cutting each time. In addition, the scissors are also easily corroded by the infused liquid, which increases the cost of use. And if the medical personnel carry the scissors on their body all the time, it is not only inconvenient, but also a great potential safety hazard...
