Description

Grinding tool

The technical field is as follows: a grinding tool, which relates to the field of nail care. In particular to a tool for trimming nails.

Background art:

the existing methods for nursing the nails of people generally comprise two methods, namely 'scissors' and 'grinding'.

The nail clipper usually works on the principle of lever, such as the nail clipper with patent number CN 201720627108.2. However, in the nail clipper, the tail end of the clip is required to be pinched with a large force in the operation process, and when the nail clipper is used for cutting the nail of the foot, the tail end of the clip is always far away from the human body, so that the user generally needs to bend down to match the clip to ensure that the user can hold the clip and can pinch the clip, and the whole operation is quite awkward. Such an operation is troublesome for the elderly who are not flexible in their hands and feet, and often causes the nail clipper to slip off and fall off due to difficulty in bending down, unstable exertion, imbalance, and the like.

The existing tools for grinding nails are generally divided into two types, one is a power tool (for example, the patent No. CN 201610348197.7), and the other is a nail file (for example, the patent No. CN 200520016062.8). Unfortunately, these two tools are not particularly suitable for the elderly to dress nails, especially for the feet with the tools. The reason is that the existing manicuring tools have the problems of poor hand feeling and poor effect caused by poor precision and poor controllability in the process of manicuring nails. To let us understand this problem better, we do not mention a single example: if one person has itching of the toes, the person can be precisely positioned and effectively controlled if the person is to treat the itching of the toes, the hand feeling is the best, and the operation method is convenient, namely the person can directly use the fingers to 'rub' the toes. On the contrary, if the method of 'holding the thin stick by hand' is adopted to 'rub' the toes, because a certain distance is always reserved between the front end of the thin stick and the grab handle, and dynamic force is frequently applied in the process of rubbing the toes, according to practical experience, the method has poor precision and poor controllability, and even sometimes can hurt the feet due to 'rubbing deviation', obviously, the final result of the method is naturally poor hand feeling and poor effect. The existing nail polishing tools are operated by holding a grinding tool with hands, so the effect of the nail polishing tool is completely similar to the effect of holding a thin stick with hands to rub the fingers of feet in the aspect of nail polishing operation.

The invention content is as follows:

the invention aims to provide a grinding tool for grinding nails, which is convenient for people with flexible hands and feet to use, is also convenient for people with inflexible hands and feet to use, and can be even convenient for blind people to use. The technical scheme is as follows:

an abrasive article characterized by: the grinding tool comprises an abrasive and a control piece; the abrasive is fixed on the surface of the finger control piece; the grinding tool is mounted on the finger of an operator to grind the fingernail.

Further: a finger leading-in hole is formed in the finger control piece; the grinder is mounted on the finger of the operator through the finger introduction hole.

Further: the finger control piece is a finger sleeve piece.

Further: the finger control piece is a finger clamping piece.

Further: the finger control piece is a hoop finger piece.

Further: the finger control piece is at least provided with two abrasive surfaces.

Further: the finger control part is provided with a finger adapting part.

Further: the finger adaptation piece is an elastic sleeve.

Further: the finger adaptation piece is an elastic ring.

Further: the finger control piece is provided with an elastic belt; the sharpener is mounted on the operator's finger by the elastic band.

Further: and a cutter and/or a file are/is arranged on the finger control piece.

The operation method or the steps (for example, the method for polishing the toenail of the right foot of the user by the right hand of the user is not the only method or the steps, but the three steps can be performed by one step):

1. fastening the abrasive tool on the right index finger of the operator through the finger introduction hole or the elastic band;

2. placing the grinding tool on the front edge of any one of the toenails of the right foot of the user, and simultaneously putting the right hand on the instep of the right foot (or holding the toe with the thumb and the middle finger) to ensure that the right hand (except the right index finger) of the user can keep effective contact with the right foot without relative movement;

3. only using the right forefinger to drive the grinding tool to grind the toenail until the toenail is ground in place;

4. the rest of the toenails are polished by the steps.

The key of the operation method or the steps is as follows: when the forefinger drives the grinding tool to grind the fingernails, the right hand and the right foot keep relatively motionless as much as possible, so that the precision and the controllability of grinding the fingernails can be well improved.

Has the advantages that:

1. the precision of the manicuring nail is improved. The finger directly controls the finger control piece, and the grinding material is directly arranged on the surface of the finger control piece, so that the operation that the distance between the front end of the existing grinding tool and the grab handle is directly shortened to be zero is equivalent to the operation that the finger directly rubs the finger, and the distance is zero, the rubbing deviation is difficult, and the precision of the nail grinding can be greatly improved compared with the existing grinding tool.

2. The controllability of manicuring is enhanced. The fingers are rubbed by the hands by a method of holding the grinding tool, and the hands are influenced by holding the grinding tool, so that the hands can only do integral motion along with the grinding tool in the process of rubbing the fingers by the grinding tool, and the motion with a certain distance is often poor in controllability and easy to deviate. On the contrary, if the grinding tool disclosed by the patent is adopted, not only is the operation of the distance zero, but also in the operation process, only the finger of the grinding tool needs to be controlled to move together with the grinding tool, and other fingers can be relatively fixed. Obviously, as a result of the combined action, the grinding tool can be stably controlled by hands in the operation process, so that the controllability of nail grinding can be greatly enhanced.

3. Good hand feeling and good effect. Adopt the grinding apparatus coping fingernail of this patent, because its precision is good, controllability is strong, therefore in whole operation process, let the operator experience "just like oneself directly scratching the sense of itching with the hand for oneself" very easily, therefore feel very good, correspondingly, the effect of coping the fingernail is also natural obvious.

4. Is suitable for many people. Because the grinding tool is used for grinding the fingernails, the hand feeling of the grinding tool is just like that the user directly scratches the fingernails with hands, and the operation is not only simple, but also can be completed by depending on the touch feeling of the body. That is, in the actual operation process, if people close eyes to do the operation, the operation can be easily realized. Therefore, the product is not only suitable for children, but also suitable for the crowd with inconvenient hands and feet, and simultaneously suitable for the blind, not to mention the common people. Further advantages can also be seen in the background, drawings, examples and in a stand-alone or combined contrast with existing products, for example, compared with the existing deficiencies of nail clippers as described in the background.

The specific implementation mode is as follows:

the present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not limited to the following examples.

Example 1 (see fig. 1):

manufacturing a finger-shaped grinding tool: the abrasive 1 and the control member 2 are made of the same material; integrally processing the grinding tool: making the finger control 2 into a finger type; a non-through finger leading-in hole 3 is formed in the finger control piece (the front end of the finger leading-in hole 3 is closed in a spherical shape); the surface of the control 2 is roughened to form the abrasive 1. The abrasive tool is preferably operated with the index finger and, accordingly, different sizes of abrasive tools are machined to accommodate different persons' index fingers.

1. fastening the grinding tool on the right index finger of the operator through the finger introduction hole 3;

4. the rest of the toenails are polished by the steps.

The key of the operation method or the steps is as follows: let the forefinger drive the grinding apparatus coping fingernail simultaneously, let right hand and right foot keep not moving relatively as far as possible, can improve the precision and the controllability of coping fingernail well like this.

In addition, the grinding tool can well improve the precision and controllability of the nail grinding, and the finger operated by an operator is almost in zero-distance contact with the ground finger, so that the grinding condition or the grinding effect of the operator on the nail can be accurately sensed and judged by the touch of the finger in time without observing the finger by eyes, and the operator can actually and completely realize the blind nail grinding.

The grinding tool for grinding the nail has the advantages that: the fingernail can be effectively polished as long as the finger can touch the fingernail. In other words, the grinding tool is used for grinding the toenails, and the toenails can be dressed by sitting on the feet without bending over. Compared with a nail clipper which can trim the toenails only by matching bending over when the feet are seated, the nail clipper has the advantages of being more obvious and prominent, and is good news for the old who are difficult to bend over.

The grinding tool has the following advantages: the nail is polished without the need of pinching or holding a tool, and the polishing can be finished by only one finger. Obviously, this advantage is not available to the comparison tools of the background art, and therefore, is a good news for the disabled who cannot repair their nails by "pinching" or "holding" the tool.
