[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0030] like Figure 1-5 The example shown is an embodiment provided by the utility model.
[0031] The embodiment of the utility model provides a pedicure knife, comprising: a knife handle 10 and a blade 20, wherein the blade 20 is detachably connected to the knife handle 10. Specifically, the front end of the knife handle 10 is connected to two arc-shaped elastic clamps 30, and the two elastic clamps 30 are arranged opposite to each other with a spacing, and the connection between the knife handle 10 and the two elastic clamps 30 is similar to the connection between the connecting handle of tweezers and the two clamp arms, and the elastic clamps 30 are in the shape of arc plates, and the two elastic clamps 30 are bent toward their respective outer sides, so that the interval between the two ends of the two elastic clamps 30 gradually increases toward the middle of the elastic clamps 30, and the blade 20 is clamped between the front ends of the two elastic clamps 30.
[0032] It can be understood that when the two elastic splints 30 are not squeezed, the front ends of the two elastic splints 30 can be in abutment with each other or with a certain interval. However, when the two elastic splints 30 are squeezed, the front ends of the two elastic splints 30 can approach each other and finally fit tightly. In specific implementation, a certain interval can be left between the front ends of the two elastic splints 30. The width of this interval is the same as the thickness of the adapted blade 20 or slightly smaller than the thickness of the blade 20, so that the blade 20 can be clamped first during the installation process, and then the clamping degree can be adjusted. Generally speaking, a blade 20 with a thickness of 0.1mm-0.3mm can be selected, which is sharper to use. Among them, the two elastic clamps 30 are provided with a strip hole 31 that penetrates each other. The strip hole 31 starts from the rear end of the elastic clamp 30 and extends toward the middle of the elastic clamp 30. The length of the strip hole 31 is close to half the length of the elastic clamp 30. The strip hole 31 is provided with a mother-and-child rivet 32. The mother-and-child rivet 32 slides in the strip hole 31, which can drive the front ends of the two elastic clamps 30 to clamp or relax each other. It can be understood that the length of the mother-and-child rivet 32 remains unchanged. When the mother-and-child rivet 32 is at the rear end of the strip hole 31, since the interval between the outer walls of the two elastic clamps 30 is the smallest here, the extrusion of the outer walls of the two elastic clamps 30 by the two ends of the mother-and-child rivet 32 is the smallest. As the mother-and-child rivet 32 slides toward the front end of the strip hole 31, the interval between the outer walls of the two elastic clamps 30 continues to increase, so the extrusion of the outer walls of the two elastic clamps 30 by the two ends of the mother-and-child rivet 32 also gradually increases, thereby forcing the two elastic clamps 30 to approach each other, thereby enabling the front ends of the two elastic clamps 30 to be clamped tighter. Conversely, sliding the mother-and-child rivet 32 backwards can relax the front ends of the two elastic clamps 30.
[0033] After adopting the above-mentioned pedicure knife, the blade 20 is clamped by two elastic clamps 30 arranged at an interval at the front end of the handle 10, and the two elastic clamps 30 are provided with strip holes 31 that penetrate each other and the mother-and-child rivets 32 that are slidably connected in the strip holes 31. The interval between the two elastic clamps 30 is adjusted by sliding the mother-and-child rivets 32 in the strip holes 31, and then the clamping degree of the blade 20 by the front ends of the two elastic clamps 30 is controlled, which makes it convenient to replace the blade 20 and can clamp the blade 20 very tightly to prevent it from falling off.
[0034] Furthermore, the inner wall of the front end of the elastic clamp 30 is a clamping wall 33, and the two clamping walls 33 are parallel to each other, so that the contact area between the two clamping walls 33 and the blade 20 is larger, and the friction between the two clamping walls 33 and the blade 20 is also larger, which can clamp the blade 20 more tightly and is not easy to slide relative to each other.
[0035] Furthermore, a positioning column 34 is provided on the inner side wall of one of the elastic clamps 30, and a positioning notch 21 is provided on the inner end of the blade 20. The positioning notch 21 is correspondingly engaged with the positioning column 34. When the blade 20 is clamped between the two clamping walls 33, the blade 20 is positioned and limited by the engagement between the positioning notch 21 and the positioning column 34, which can not only conveniently clamp the blade 20 in the correct position, but also limit the left and right movement of the blade 20. At the same time, when the two clamping walls 33 are clamped together, the end of the positioning column 34 can abut against the inner side wall of the other elastic clamp 30, thereby preventing the blade 20 from being clamped between the two elastic clamps 30 for too long and affecting the use of the blade 20.
[0036] Furthermore, a connecting hole 35 is provided on the inner side wall of the other elastic clamp plate 30 , and the positioning column 34 is plugged into the connecting hole 35 correspondingly, which can prevent the inner end of the blade 20 from passing through between the positioning column 34 and the inner side wall of the elastic clamp plate 30 .
[0037] Specifically, two positioning posts 34 are arranged at intervals, and the number and spacing of the positioning notches 21 and the connecting holes 35 correspond to those of the positioning posts 34 .
[0038] Specifically, the parent-child rivet 32 includes a nail column 321 and two nail heads 322. The nail column 321 is slidably inserted in the strip hole 31. The two nail heads 322 are respectively connected to the two ends of the nail column 321, and the inner side walls of the nail heads 322 are slidably abutted against the outer side walls of the elastic clamping plates 30. In a preferred embodiment, the length of the nail column 321 is equal to the sum of the thicknesses of the two elastic clamping plates 30, so that the inner side walls of the two nail heads 322 can simultaneously slide against the outer side walls of the two elastic clamping plates 30 regardless of the position of the strip hole 31.
[0039] Specifically, the strip hole 31 is a straight slot hole, the diameter of the nail head 322 is larger than the width of the strip hole 31 to prevent the nail head 322 from passing through the strip hole 31, and the width of the strip hole 31 is larger than or equal to the diameter of the nail column 321 to facilitate the nail column 321 to slide smoothly in the strip hole 31.
[0040] Furthermore, the outer side walls of the two elastic clamping plates 30 are respectively provided with anti-skid structures 36 to prevent the user from slipping during use. The anti-skid structures 36 may be a plurality of anti-skid grooves or anti-skid strips, or may be a covering layer of anti-skid material.
[0041] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the utility model specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the utility model.
