Detailed Description
The following description of the preferred embodiments of the present invention will be made in conjunction with the drawings and the accompanying drawings to further illustrate the technical means adopted to achieve the objects of the present invention.
Referring to fig. 1 to 6, a first preferred embodiment of the multi-sheet type safety cutting blade of the present invention is used for cutting one of an adhesive tape, a film and a paper roll, and includes a first body 10, a second body 20 and a safety margin S.
The first body 10 can be a sheet, such as a metal sheet, the top of the first body 10 has a cutting portion 11, the cutting portion 11 has a knife edge 111, and the knife edge 111 can be a straight knife edge 111. The second body 20 is combined with the first body 10, the top of the second body 20 is provided with a plurality of safety lugs 21 which are arranged at intervals, and a plurality of grooves 22 which are arranged at intervals are formed among the safety lugs 21; the safety margin S is located above each safety protrusion 21 of the second body 20, and a vertical distance H1 from a top surface of each safety protrusion 21 is 0.5 millimeters (mm), and the cutting edge 111 of the cutting part 11 is exposed out of the groove 22 of the second body 20 and does not protrude beyond the safety margin S.
Since the top of the second body 20 has the plurality of safety protrusions 21 arranged at intervals, and the cutting edge 111 of the cutting portion 11 is not higher than the safety boundary S, when a user touches the top of the multi-piece safety cutting blade, the plurality of safety protrusions 21 can provide a stop protection effect, thereby reducing the chance that a finger directly touches the cutting edge 111, and even if the skin of the finger touches the cutting edge 111, the cutting depth of the cutting edge 111 into the epidermis can be limited, so that the cutting edge 111 can only hurt the cuticle for protecting the skin, and the safety of the multi-piece safety cutting blade is improved.
In the first preferred embodiment, the second body 20 has two side plates 201,203 and a top plate 202, the two side plates 201,203 are respectively combined with two opposite sides of the first body 10, the top plate 202 is covered on the top of the first body 10, the plurality of grooves 22 are formed on the top plate 202 of the second body 20 at intervals and penetrate through the top plate 202, the plurality of safety protrusions 21 are formed on the top plate 202 at intervals, and the knife edge 111 of the cutting portion 11 of the first body 10 is exposed out of the grooves 22 of the second body 20 and is lower than the top surface of each safety protrusion 21. Preferably, the distance D between two adjacent safety lugs 21 is less than or equal to 3 mm, and greater than or equal to 0.2 mm, preferably greater than or equal to 0.35 mm, and the perpendicular distance H2 between the knife edge 111 and the top surface of each safety lug 21 is less than or equal to 0.5 mm.
Because the knife edge 111 of the cutting part 11 is lower than the top surface of each safety bump 21, and the cutting part 11 is covered by the safety bumps 21, when a user touches the top of the multi-piece safety cutting blade, the user will touch the top surfaces of the safety bumps 21 first to avoid directly touching the cutting part 11 of the first body 10, and because the vertical distance H2 between the knife edge 111 and the top surfaces of the safety bumps 21 is less than or equal to 0.5 mm, the problem that the tape is difficult to cut due to the overlarge height difference between the knife edge 111 and the top surfaces of the safety bumps 21 can be avoided.
Referring to fig. 7 to 10, in a second preferred embodiment, the second body 20A is a sheet body, such as a metal sheet body or a plastic sheet body, and is combined to one side of the first body 10A, a plurality of the grooves 22A are formed at the top of the second body 20A in an interval arrangement, a plurality of safety bumps 21A are formed between the grooves 22A in an interval arrangement, a knife edge 111A of the cutting portion 11A of the first body 10A is exposed out of the groove 22A of the second body 20A and is lower than the top surface of each safety bump 21A without protruding the safety margin S, the knife edge 111A is located at a side of the first body 10A adjacent to the second body 20A, and a vertical distance H2 between the knife edge 111A and the top surface of each safety bump 21A is smaller than or equal to 0.5 mm.
Since the knife edge 111A of the cutting portion 11A is lower than the top surface of each safety bump 21A, when the user touches the top of the multi-piece safety cutting blade, the user will first touch the top surfaces of the safety bumps 21A to avoid directly touching the cutting portion 11A of the first body 10A, and the distance H2 between the knife edge 111A and the top surfaces of the safety bumps 21A is less than or equal to 0.5 mm, so as to avoid the problem that it is difficult to cut the tape due to the large height difference between the knife edge 111A and the top surfaces of the safety bumps 21A.
Referring to fig. 11 and 12, in a third preferred embodiment, the second body 20B is a sheet body combined with one side of the first body 10B, a plurality of the grooves 22B are formed at intervals on the top of the second body 20B, a plurality of safety protrusions 21B are formed at intervals between the grooves 22B, a knife edge 111B of the cutting portion 11B of the first body 10B protrudes out of the top surface of each safety protrusion 21B and is not higher than the safety boundary S, the knife edge 111B is located at one side of the first body 10B adjacent to the second body 20B, a vertical distance H2 between the knife edge 111B and the top surface of each safety protrusion 21B is less than or equal to 0.5 mm, and the knife edge 111B can be flush with the safety boundary S.
Since the knife edge 111B of the cutting portion 11B protrudes out of the top surface of each safety bump 21B and does not protrude out of the safety boundary S, the adhesive tape can contact the knife edge 111B first in the process of pressing down, so that the adhesive tape is easier to cut and cut, even if a finger touches the multi-piece safety cutting blade, the knife edge 111B is still touched, but the safety bumps 21B arranged at intervals can provide a limiting protection effect, and after the finger touches the safety bumps 21B, the pressing down is not continued, so that the chance that the knife edge 111B penetrates through the skin is reduced, in addition, the thickness of the cuticle of the skin is about 0.5 mm, so that even if the epidermis is scratched by the knife edge 111B, only the cuticle without nerves and blood vessels is injured, bleeding is avoided being cut, and the safety of the multi-piece safety cutting blade is improved.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person can make modifications or changes equivalent to the equivalent embodiment without departing from the scope of the present invention, but all the technical matters of the present invention are within the scope of the present invention.
