Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.

As shown in Figure 1, a kind of cosmetically nasal cavity D type knife, including handle 1 and the knife bar 2 for being connected to 1 both ends of handle, The knife bar 2 is equipped with D type cutter head 21, and the profile of the vertical section of the handle 1 is circle, i.e., the described handle 1 is actually One cylinder is respectively equipped with the first aperture 121 and the second aperture 122 on the both ends circumferential surface of the handle 1, and circumferential surface here refers to The face contacted when in use with hand, first aperture 121 and the second aperture 122 are oval, i.e., described first aperture 121 Long axis and short axle are all had with the second aperture 122, the long axis of first aperture 121 is parallel with the length direction of the handle 1, The long axis of second aperture 122 is vertical with the length direction of the handle 1, and second aperture 122 is compared to the first aperture 121 closer to the middle part of the handle 1, set on the quantity at least two of first aperture 121 of every one end of the handle 1.

It, can be by the finger of the thumb of hand and index finger when in use when a kind of cosmetically nasal cavity D type knife of the present embodiment It is pressed into and is pressed into first aperture 121 respectively, the side of middle finger is resisted against in second aperture 122, at this point, index finger Almost the same with the length direction and the long axis direction of corresponding first aperture 121 of thumb, middle finger is supported with the second aperture 122 Almost the same by the length direction at position and the length direction of the second aperture 122, this completes one kind to the present embodiment The cosmetically grasping of D type knife, since index finger and thumb have been pressed into corresponding first aperture 121, middle finger is resisted against accordingly In second aperture 122, stable grasping can be realized, prevent from sliding in use, it should be understood that described first opens The long axis length optimal setting of hole 121 and the second aperture 122 is between 0.6-1.2cm, and minor axis length optimal setting is in 0.5- Between 0.8cm, to avoid because Kong Tai great causes finger to be pressed into hole completely, or due to Kong Tai little, does not have aperture and answer When the effect having.

Further, the quantity set on first aperture 121 of the every one end of the handle 1 is three and is located at same perpendicular Interior, the quantity set on second aperture 122 of the every one end of the handle 1 is also three and in the same perpendicular, described the One aperture 121 and the second aperture 122 are corresponded along the lengthwise location of the handle 1, the advantages of this arrangement are as follows: food Refer to that middle finger can find corresponding second aperture 122 while arbitrarily selecting two in three the first apertures 121 with thumb.

In order to further enhance the convenience of operation, cladding is equipped with elastic tape 13 on the middle part circumferential surface of the handle 1.

Further, the handle 1 includes core 11 and shell 12, and the shell 12 is coated on 11 outer surface of core, The core 11 is column, and first aperture 121 and the second aperture 122 are opened on the shell 12 and through the shells 12 shell wall, when hand complete grasp when, the finger of index finger and thumb is contacted with the surface of core 11, the side of middle finger also with core The surface of body 11 contacts.

Further, there is gap between the inner wall of the shell 12 and the outer wall of the core 11；Specifically,

With the gap of 0.1-0.5cm between the inner wall of the shell 12 and the outer wall of the core 11.In this way After setting, when completing grasping, the meat of finger finger is limited in first aperture 121 or the second aperture 122, due to The setting in gap, the meat of finger finger meeting miniature deformation under squeezing action, into gap, so that hand can be grabbed steadily very much A kind of cosmetically nasal cavity D type knife that residence is stated, meanwhile, finger finger is also contacted with the surface of core 11, and that give refer to first Stress point avoids finger finger from being excessively entering into the first aperture 121 or the second aperture 122, causes the pain of finger.

Specifically, the shell 12 is a columnar hollow shell, the core 11 is located in the shell 12, described Knife bar 2 is connected after passing through the shell 12 with the core 11.

Vertical section described in the present embodiment is that one kind of the present embodiment is perpendicular when cosmetically D type knife level is put Section, the perpendicular is a kind of the present embodiment plane perpendicular when cosmetically D type knife level is put.

The above-mentioned description to embodiment is to understand convenient for those skilled in the art and using originally practical new Type, person skilled in the art obviously easily can make various modifications to embodiment, and described herein general Principle is applied in other embodiments without having to go through creative labor.Therefore, the utility model is not limited to the above embodiments, Those skilled in the art's announcement according to the present utility model, does not depart from improvement that the utility model scope is made and modification is all answered This is within the protection scope of the utility model.
