Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As in Figure 3-5, a kind of safety blade, comprise cutter hub 1, cutter head 2 and installation portion 3, cutter hub 1 edge is provided with the edge of a knife 4, installation portion 3 is in opening channel-shaped or poroid, cutter hub 1 is installed on the apparatus of handle of a knife or other blades to be used by installation portion 3, protection portion 5 is also provided with in the edge of a knife 4 and cutter head 2 junction, protection portion 5 overall appearance is blunt bulk (bulk as blunt in circle or oval blunt bulk), in arcuation or curved outside protection portion 5, thickness is more than or equal to the thickness of cutter hub 1, the article in packing case and user is scratched when the blade of design like this can effectively prevent blade from using.
In addition, the utility model safety blade establishes a cutter head to meet instructions for use usually, but also can establish two cutter heads 2 (as shown in Figure 6) respectively at cutter hub two ends, correspondingly, two cutter heads is all provided with protection portion.Can change in time when one end edge of a knife weares and teares and use the opposite side edge of a knife, clearly, one piece of blade arranges two cutter heads does not increase too many production cost, but improves operating efficiency.
