Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and
Embodiment, is further elaborated to the present invention.Should be appreciated that described herein being embodied as
Example only in order to explain the present invention, is not intended to limit the present invention.
As in Figure 3-5, a kind of safety blade, including cutter hub 1, cutter head 2 and installation portion 3, cutter hub 1
Edge is provided with the edge of a knife 4, and installation portion 3 is in opening channel-shaped or poroid, and cutter hub 1 is installed on cutter by installation portion 3
On the apparatus of handle or other blades to be used, it is additionally provided with protection portion 5 in the edge of a knife 4 and cutter head 2 junction, protects
Protecting portion 5 overall appearance is blunt bulk (such as circular blunt bulk or oval blunt bulk), in arc outside protection portion 5
Shape or curved, thickness is more than or equal to the thickness of cutter hub 1, and the blade being so designed that can effectively prevent blade
The article in packing crates and user is scratched during use.
Additionally, safety blade of the present invention generally sets a cutter head can meet use requirement, but also can be at cutter
Body two ends set two cutter heads 2 (as shown in Figure 6) respectively, correspondingly, two cutter heads are designed with protection portion.
The use opposite side edge of a knife can be changed in time, it is evident that arrange on one piece of blade when one end edge of a knife weares and teares
Two cutter heads do not increase too many production cost, but improve work efficiency.
The cutter hub of safety blade of the present invention can be provided with inclined-plane at side outward flange, it is possible to is provided with in both sides of the edge
Inclined-plane, inclined-plane forms the edge of a knife 4.Certainly, the specific needs used according to blade, the edge of a knife can be configured as it
His shape, such as arc or sector.
The protection portion (5) of safety blade of the present invention is metal blocks or plastic blocks, and protection portion periphery sets
There is chamfering, to increase the passivity of protection portion, improve the safety of blade further.During use, such as Fig. 5
Shown in, first safety blade cutter head penetrates papery tank wall, keeps the edge of a knife to contact with papery tank wall, slowly moves
Moving knife body, can scratch paper box body.Even if the most excessive, blunt due to safety blade protection portion
Property, will not scratch or scratch the article in case.And, even if careless manipulation when using, the most do not cause wound
To operator's health.
In a word, safety blade of the present invention can be widely used in individual, family tears express delivery packaging or household electrical appliance open
