When all the folded edges 121 are folded backward and enclosed to form a three-dimensional handle, the buckle 126 is locked in the corresponding first buckle hole 127. With the above arrangement, the two folded edges 121 located on the outside can be conveniently connected together.

[0037] Reference Figure 5 and Figure 6 According to some embodiments of the present invention, the buckle 126 includes a column 1261, a block 1262 is formed on the periphery of the column 1261, and a formed avoidance hole 125 is provided on the corresponding folding edge 121. The formed avoidance hole 125 is arranged corresponding to the block 1262. With the above arrangement, the buckle 126 and the folding portion 120 can be integrally formed. When all the folding edges 121 are relatively folded and enclosed to form a three-dimensional handle, the column 1261 is inserted into the corresponding first clamping hole 127, and the block 1262 is clamped with the side wall of the corresponding first clamping hole 127, thereby realizing that the two folding edges 121 located on the outside are clamped together.

[0038] Reference Figure 5 In the specific implementation process, the buckle 126 is arranged on the rear side of the folding portion 120. Therefore, when all the folds of the folding portion 120 are folded relative to each other to form a handle, the buckle 126 is located on the inner side of the handle to prevent the buckle 126 from hitting the hand.

[0039] It should be noted that the above-mentioned buckle 126 can also be set in other ways. For example, the buckle 126 can be set as a T-shaped protrusion. After the T-shaped protrusion passes through the first clamping hole 127, the protrusions on both sides of the T-shaped protrusion can be clamped on the side walls of the first clamping hole 127.

[0040] Reference Figure 1 and Figure 2In the specific implementation process, four folding edges 121 are provided, and the upper ends of the two folding edges 121 located in the middle are provided with first connecting parts 122, and the two first connecting parts 122 are relatively open. The head 110 is provided with two first avoidance holes 114, and the head 110 forms a second connecting part 115 between the two first avoidance holes 114. The two first connecting parts 122 are located in the two first avoidance holes 114 one by one, and the second connecting part 115 is located between the two first connecting parts 122 and connected to the two first connecting parts 12 2, an arc-shaped second bending groove 124 is arranged between the second connecting portion 115 and the two first connecting portions 122, and the first bending groove 123 located between the two folding edges 121 in the middle is connected with the two second bending grooves 124. With the above arrangement, after the folding portion 120 is folded to form a handle, the two first connecting portions 122 can be supported on the rear side of the head 110, thereby enhancing the strength between the head 110 and the folding portion 120, and preventing the head 110 from bending backward relative to the folding portion 120 to affect the normal use of the card razor.

[0041] Reference Figure 2 and Figure 3 According to some embodiments of the utility model, the head 110 is located on the upper side of the folding portion 120, and the positioning structure includes three convex strips 111 arranged side by side on the front side surface of the head 110, the convex strips 111 are arranged along the up-down direction, and at least one positioning groove 1111 is arranged on the convex strips 111. The bottom surface of the positioning groove 1111 is inclined relative to the up-down direction, and the blade 210 is placed in the corresponding three positioning grooves 1111 and abuts against the bottom surface of the corresponding positioning groove 1111. With the above arrangement, the blade 210 is supported by the convex strips 111 at both ends and the middle position to prevent the blade 210 from bending and affecting the use during the use of the razor.

[0042] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, each convex strip 111 may be provided with three positioning grooves 1111 , thereby, one blade 210 , two blades 210 , or three blades 210 may be placed on the three convex strips 111 as needed.

[0044] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, a positioning protrusion 1112 is provided on the bottom surface of each positioning groove 1111, and the blade 210 is provided with three positioning holes 211, and the positioning protrusions 1112 are inserted into the corresponding positioning holes 211 to make the blade 210 more firmly installed.

[0045] It should be noted that, in other embodiments, the above-mentioned positioning structure may also be arranged in other ways. For example, the above-mentioned three convex strips 111 may be made into one convex strip 111 .

[0046] Reference Figure 2 and Figure 4 According to some embodiments of the utility model, a sheath 220 is provided with a slot, and a blade 210 is inserted into the corresponding slot. A plurality of second avoidance holes 221 are provided on the sheath 220 at intervals along the length direction of the blade 210. The second avoidance holes 221 are connected to the slot, and the second avoidance holes 221 are located at the edge of the blade 210 to expose the edge of the blade 210. With the above arrangement, the blade 210 can effectively avoid scratching the user during the use of the razor.

[0047] According to some embodiments of the present invention, the wall thickness between two adjacent second avoidance holes 221 is 0.2 mm to 0.5 mm, and the width of each second avoidance hole 221 is 0.8 mm to 2 mm. The above arrangement can ensure that the blade 210 can shave hair normally.
