Description

Safety protection nail clippers

This creative department belongs to the field of personal cleaning equipment, especially for the safety protection nail clippers for adjusting the cutting opening of the patient’s proliferative nails. The connecting elastic design of the scissors feet must be used to adjust the size of the cutting opening and prevent it. The injured design is for patients who can cut their nails by themselves.

Press, because the use of traditional scissors to cut nails requires a certain level of skill, and it is easier to cause injuries due to careless operation. Therefore, nail clippers designed for cutting nails have appeared on the market. At present, a general nail clipper includes a lower blade plate, an upper blade plate and an operating plate. The upper blade plate and the back end of the lower blade plate are connected to each other. They are pivotally connected to each other as a whole, and the front ends of the upper blade and the lower blade are respectively provided with a blade portion aligned with each other, so that a cutting slit is formed between the two blade portions, and the width of the slit is determined by The separation distance between the two blades is determined. Generally speaking, the separation distance is determined by the length of a pivot between the operating plate and the upper and lower blades, and the length of the pivot is usually kept fixed When the nail is cut off, the operating plate links the upper knife plate to approach the lower knife plate along the pivot axis, causing the two blades to move relative to each other to clamp the cut nail.

However, because most diabetic patients have symptoms such as crimped nails, ingrown nails (paronychia), and onychomycosis, and diabetic patients’ wounds are not easy to heal due to poor blood circulation, they may eventually be caused by tissue necrosis, suppuration, and infection. The fate of having to amputate. Therefore, for nail problems that are prone to foot wounds, such as: curled nails, also known as pincer nails, sagging nails, which are an unnaturally bent state of the nails, which can cause pain in the nail area. If left alone, it may cause Nail bed wilt Shrinkage, curl nails are caused by atrophy of the nail bed tissue on both sides of the nails and loss of support, causing the nails on both sides to bend down; ingrown nails are the nails growing into the flesh, and the early ingrown nails are only painful, but because It is easy to be complicated by nail groove tissue infection, so it is also called paronychia. Onychomycosis is nail or toenail infection caused by fungal nail discoloration, deformation, thickening, scaling, roughness and fragility, nail separation and other phenomena. Onychomycosis is the most common nail disease. The above three foot symptoms are very troublesome and serious for diabetic patients. Because these symptoms must be properly maintained by trimming their nails.

However, with the current nail clippers, the cutting opening is too small to be adjusted. When the nails are thickened or deformed, they cannot be used directly. Therefore, special nail scissors must be used for trimming. These special nail scissors are also Professionals are required to perform the operation. For diabetic patients, it is quite inconvenient to not be able to trim and maintain at home; therefore, although there are nail clippers on the market that can adjust the size of the cutting opening by adjusting the length of the pivot, it is limited to the nails. The length after entering the cutting mouth must be repeatedly operated and adjusted. For diabetic patients with poor eyesight, there is still a certain degree of difficulty in operation. The special nail scissors are mostly designed with oblique blades, and they are cut off by oblique entry. The self-operated operators cannot observe the distance between the nail length and the skin from the side. For example, it is not easy to cut wounds. Healing increases the difficulty of subsequent treatment, so it is necessary to improve it.

In view of this, one purpose of this creation is to provide a safety and protective nail clipper, which uses a connecting structure and an elastic element in the shape of scissors feet to connect between an upper blade and a lower blade, respectively, through the connection The structure can quickly adjust the size of the cutting opening without affecting the internal space, and the connecting structure can also link a protective element to prevent users from operating Cut the skin by mistake to ensure that the skin will not enter the cut opening, which greatly improves the convenience and safety of use.

In order to achieve the above purpose, the safety protection nail clippers of this creation include: an upper blade plate, one end of which is provided with a first joint part, and the other end is bent downward to be provided with an upper cutting edge; the lower blade plate, one end of which corresponds to The first joint part is provided with a second joint part, and the other end is corresponding to the upper cutting edge and is bent upward with a lower cutting edge to connect the first joint part and the second joint part into one body, so that the A shearing opening is formed between the upper and lower cutting edges and an accommodating space is formed inside; an operating plate is pivotally connected to the top surface of the upper knife plate, after being rotated, the operating plate and the upper knife plate can be formed An operating angle for pushing the upper knife board to move in the direction of the lower knife board to close the cutting opening to generate the force of cutting the nail; at least one connecting structure, the one connecting structure is connected to the upper, Between the lower blades, the connecting structure includes an upper connecting seat, a lower connecting seat, two first connecting pieces, and a second connecting piece. The upper connecting seat is arranged on the upper blade, and the lower connecting seat is arranged on the lower connecting seat. A knife board, the upper connecting seat is provided with an upper fixed part and an upper movable part, the lower connecting seat is provided with a lower fixed part and a lower movable part, and the two first connecting pieces are formed by clamping the second connecting piece. The center can be pivotally connected to the movable cross type, and the upper and lower ends of the two first connecting pieces and the second connecting pieces are respectively connected to the upper fixed portion, the upper movable portion, the lower fixed portion and The lower movable portion adjusts the size of the cutting opening by changing the position of the lower end portion of the two first connecting pieces on the lower movable portion and the upper end portion of the second connecting piece on the upper movable portion; an elastic element , Set between the upper and lower blades, and the elastic element is used to keep the upper and lower blades apart in a normal state; and at least one protective element is provided under the lower blade, and a part of the protective element It extends to the outer side of the lower blade for contact with the skin; accordingly, when adjusting the relative positions of the three connecting pieces on the upper and lower connecting seats, the opening size of the cutting opening can be adjusted, and the protective element is used The distance between the skin and the cutting opening can be adjusted to prevent the nail clip from being too short or too deep to damage the skin tissue, and greatly improving the convenience and safety when cutting the nail.

In one embodiment, the safety protection nail clippers of the present invention further have a lighting element and a sensor, the lighting element is arranged on the outer side of the upper blade, and the sensor is installed on either of the upper and lower blades The sensor is electrically connected to the lighting element to provide the brightness of illuminating the cut opening, and the sensor is connected to the protective element, when the skin is against the protective element Sometimes the sensor is triggered to activate the lighting element to light up.

Furthermore, another part of the protective element is connected to the connecting structure, and when the connecting structure is adjusted, the protective element is moved together to ensure that the user's skin does not enter the cut opening. .

In addition, the safety protection nail clipper of the present invention has a reminder unit that is electrically connected to the sensor, and can remind the user that the cutting opening has reached the cutting position with the sound and light effect.
