Abstract

One group of cutting blade, comprising an interior pipe that can in an outer tube, rotate, with the slotted eye that at each described Guan Zhongyou is axial stretching, extension basically, but also at least one edge of each slotted eye is sharpened, when interior pipe rotated, the edge of sharpening of these two slotted eyes cut off the material that stretches into the slotted eye on the outer tube with regard to co-operating.

Description

Cutting blade

The present invention relates to be used for a kind of cutting blade of cutter, especially relate to the blade that is used to cut the unguis hominis, (though this kind cutting blade be specifically designed to absolutely not cutting unguis hominis), and be equipped with that this kind cut the nail blade cut the nail device.

Traditional method of trimming the nails comprises uses nail clipper or nail nipper.But these two kinds of instruments all can not equally easily be operated with the right-hand man.These two kinds of instruments are for hand-power weak person, and for example the older also is very difficult even can operate, and the burr that cut out also need with nail file finishing afterwards, and nail file may damage near the soft tissue the nail in addition.Another shortcoming is that the always uncontrollable usually ground of nail filings disorderly flies, and also needs to collect after trimming the nails.

What the purpose of this invention is to provide a kind of cutting blade and this kind cutting blade is housed cuts the nail device, and this kind cut the nail device can overcome above-mentioned shortcoming at least to a certain extent.

The invention provides one group of cutting blade, comprising the interior pipe that can in an outer tube, rotate, with the slotted eye that at each described Guan Shangyou is axial stretching, extension basically, but also at least one edge of each slotted eye is sharpened, when interior pipe rotated, the edge of sharpening of these two slotted eyes cut off the material in the slotted eye that stretches on the outer tube with regard to co-operating.

Outer tube also can be circular.

Two edges of each slotted eye all can be sharpened.

The edge of outer tube slotted eye can be parallel with the longitudinal axis of pipe.

Slotted eye edge on the interior pipe can separate outwardly away from each other gradually to an end of pipe.

The size of determining the outer tube slotted eye can stretch into it for the nail edge.

Slotted eye or two slotted eyes all can ground directly extend to an end of its tube wall.

Cut the nail device for one and can comprise one group of above-mentioned cutting blade.

Cutting the nail device can have a handle, and this outer tube then is fixed on this handle, drive unit also is housed rotates interior pipe.

A finger holder can be connected with this handle, help nail to be cut is stretched in the slotted eye on the outer tube.

Drive unit can comprise a motor that is connected with interior pipe by gear train.

Interior pipe can sufficiently high speed drive, makes the camber line of nail edge by the slotted eye on the outer tube scan action and causes many otch, thereby make the incisxal edge of nail smooth.

Drive unit can also drive a fan again, and the hole by interior pipe blows or suction air, and the first bits are collected or sent.

The two edges of each slotted eye can be sharpened, but motor bi-directional drive then.

Explanation below reading just can be understood the present invention also with reference to the accompanying drawings more, and accompanying drawing is only used the mode of example, shows cutting the nail device and the cutting blade that formation is cut the nail device being housed of a kind of form.Accompanying drawing is as follows:

Fig. 1 cuts the perspective view that nail general ability portion is dissectd;

Fig. 2 is for cutting the decomposition diagram of nail device major part among Fig. 1;

Fig. 3 is for cutting the magnification ratio side view of nail device set of blades outer tube among Fig. 1;

Fig. 4 is for cutting the magnification ratio side view of pipe in the nail device set of blades among Fig. 1.

Now referring to Fig. 1 and 2, cut the nail device as can be seen from Figure a handle is arranged, represent with label 10, internal battery 11, a dc motor 12 and a solar reduction gear system, gear train is represented with label 13, and the switch 14 of motor 12, and this switch can be handled this motor and do forward and reverse rotation.

Cut the nail device and one group of cutting blade is arranged comprising an interior pipe 15 and an outer pipe 16.Two Guan Douyong steels are made.Interior pipe 15 has a slip equipment in outer tube 16, and available motor 12 makes its high speed rotating in outer tube 16 by gear train 13.Outer tube 16 is that benchmark is fixed with handle 10.

Basically be the slotted eye of axially aiming at 17 and 18, stretch into the part of the length of this pipe by the free open end of inner and outer pipes 15 and 16 respectively.

Two edges of slotted eye 17 separate outwardly away from each other gradually towards the free end of pipe 15, and two edges are all sharpened.

Two edges of slotted eye 18 are all parallel with the longitudinal axis of pipe, but also two edges are sharpened.

Determine the size of the slotted eye 18 on the outer tube 16, people's nail can be entered, near soft tissue then can't enter.In general, its length L (see figure 3) is 11.5mm, and its width W is between 1 to 2mm, obviously, different size can be provided and be suitable for different nail thickness.The typical thickness of outer tube wall is 0.25mm.

In the slotted eye 17 of pipe on 15 be placed on pipe 16 and be provided with in slotted eye 18 that part of, and have length 14mm and narrow to the width of 0.8mm gradually by 3.5mm.

One holds this and cuts the nail device during use, and the rotation direction of motor 12 is when interior pipe 15 rotations, and the edge of slotted eye 17 is the edge by slotted eye 18 downwards just.Each nail of another hand is put into slotted eye 18 in turn scan action as camber line inside.Should in pipe being enough to form the high-speed rotation of fully many adjacent cut, and make the nail edge of pruning very smooth.

Adorn a finger holder 20 at the blade adjoiner, be beneficial to the nail cutting operation.

Obviously, when the action of cutting nail, do not need firmly the method for this kind cutting nail, not only no pain but also very comfortable.

What should be understood that is, we only are limited to above-mentioned example with the present invention unintentionally, various variations, for example the staff in those present technique fields be easy to expect and the variation that do not exceed the invention scope that appended claims defines all is possible.

Therefore, for example, this is cut the nail device and not necessarily will take with hand.Also want can adorn on the table, in the case, this motor only need drive with a direction, and only an edge of each slotted eye need be sharpened.

In addition, again for example, the useable electric moter drive fan, the hole by interior pipe blows or suction air, the nail filings in the interior pipe is collected or dispatch is gone in the collecting chamber.
