Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention can be easily understood by those skilled in the art from the disclosure of the present specification.

It should be understood that the drawings of the present application are designed to show the structure, ratio, size and the like only for the purpose of disclosure, so as to be understood and read by those skilled in the art, and not for the purpose of limiting the present invention, so that the present invention is not limited to the practical limitations, and therefore, the present invention is not limited to the essential technical meaning, and any modification of the structure, change of the ratio or adjustment of the size should still fall within the scope of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle", "inner", "outer" and "a" used in the present specification are used for clarity of description only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof should be regarded as the scope of the present invention without substantial changes in the technical contents.

As shown in fig. 1 to 7, the embodiment of the present invention is that, as shown in fig. 1, a toenail removing knife, including a blade 1 and a handle 2, a spherical protrusion 10 is provided on the tip of the blade 1, the blade 1 is provided with a through hole 11, the handle 2 is provided with a groove 30, the blade 1 passes through the inner edge clamping groove 30 of the through hole 11, so that the blade 1 is detachably connected with the handle 2.

Preferably, as shown in fig. 1 or 3, the blade 1 has a right-angled trapezoid shape with a longer oblique side, the cutting edge 12 being on the oblique side of the trapezoid, and the tip being located at one end of the cutting edge 12.

As shown in figure 1 or figure 3, the knife point of the blade 1 is provided with a spherical bulge 10, so that the blade 1 can not accidentally injure normal tissues when extending into subungual tissues to remove the nail. Preferably, the spherical projection 10 has a spherical diameter of 1.5 mm.

Preferably, as shown in fig. 1 or fig. 4 or fig. 6, the shape of the tool shank 2 is round-head flat.

The head of the knife handle 2 is provided with a convex part 3. Preferably, as shown in fig. 1, 2, 6 or 7, the projections 3 are kidney-shaped. Preferably, the protruding part 3 is integrally connected with the tool holder 2, so that the connection strength is high and the processing is convenient. Preferably, the handle 2 is provided with stripes 4 to facilitate holding.

Preferably, as shown in fig. 6 or 7, the stop 31 is a flat and/or curved surface disposed within the slot 30. The stopper 31 serves to prevent the blade 1 from coming off by stopping the movement of the blade 1 in the direction of the holder 2 when the replacement of the blade 1 is completed. On the other hand, when the blade 1 is removing the nail, the blade 1 can be prevented from falling off the boss 3.

Preferably, as shown in fig. 2 or 5, the groove 30 is concave in shape to facilitate its machining.

Preferably, the through hole 11 includes a first through region 110 and a second through region 111, and as shown in fig. 3, the first through region 110 is U-shaped, which is convenient to process and beautiful.
