Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or components/elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

An ear band scissors according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a front view of an ear band scissors according to an embodiment of the present invention. As shown in figure 1, the ear scissors comprise a knife handle 1, a shaft hole 2 is formed in the center of the knife handle 1, a compression shear groove 3 is formed in the upper end of the knife handle 1, a knife body 4 is arranged at the side end of the knife handle 1, a knife outer opening 5 is formed in one end of the knife body 4, a cutting edge 6 is arranged on the outer side of the knife outer opening 5, the front plane of the knife handle 1 is parallel to the front plane of the knife body 4, and the back plane of the knife handle 1 is parallel to the back plane of the knife body 4.

According to the utility model discloses an embodiment, the positive plane of handle of a knife 1 and the positive plane of blade 4 are the coplanar.

According to the utility model discloses an embodiment, the back plane of handle of a knife 1 and the back plane of blade 4 are the coplanar.

According to an embodiment of the utility model, the material of handle of a knife 1 is pottery.

Specifically, the conventional tools are each provided with a raised step at the shank 1, and the steps are used for enhancing the clamping force of the clamp and the tool when the tool is assembled on a machine tool and enabling the tool to be clamped in a cross direction. However, at the same time, this raised step, which is one of the major wear points of the tool when it is in use, takes on the clamping task. The utility model discloses a ceramic material preparation handle of a knife, generally, whole cutter all utilizes same material when producing the cutter, and blade 4, sword outer mouthful 5 and blade 6 etc. are ceramic material promptly. However, when the ear band of the mask is cut off, the cutting edge 6 and the knife outer opening 5 are not worn basically because the ear band is made of soft material, and the protruding step of the traditional knife on the knife handle becomes a main wear part. And the embodiment of the utility model discloses an embodiment adopts the theory of equidensity design, and fig. 2 is the utility model discloses a bottom view of ear area scissors that another embodiment provided, as shown in fig. 1-2, design into the positive plane coincidence with blade 4 with the positive plane of the handle of a knife 1 of ceramic cutter, the back plane of handle of a knife 1 and blade 4 with the same reason also designs into same plane, cancels the step of traditional cutter on the handle of a knife for the anchor clamps of lathe with the utility model discloses an ear area scissors becomes parallel relation when pressing from both sides tightly, the contained angle does not appear. Therefore, when the clamp and the cutter are clamped, abrasion can be obviously reduced, equal-strength design is realized, and the service life of the whole cutter is obviously prolonged.

If the cutter is made of materials such as high-plastic steel and the like, the structure of the utility model can be cut off, but the cutter and the clamp can only be cut off for several times to fail due to insufficient matching precision, and the practicability is low. The utility model discloses utilize ceramic material to make, because ceramic is wear-resisting, at the assembly position of cutter, including handle of a knife 1, shaft hole 2 and the machining precision of compression shear groove 3 department can polish than higher to it is not enough to have solved general material and equipped the precision, the unable tight problem of clamp. Simultaneously, the utility model is used for when cutting this kind of softer material of ear area, also can not produce too high shearing force to the portion of clamping.

On the other hand, the conventional tool has a step at the tool shank, and additional consumables are generated at the tool shank 4 and the tool body during machining. The utility model discloses an in the embodiment, the front plane of handle of a knife 1 and the front plane of blade 4 are the coplanar, and the back plane of handle of a knife 1 and the back plane of blade 4 are the coplanar, thereby make the utility model discloses the production consumptive material is few, and is with low costs, energy-concerving and environment-protective.

According to the utility model discloses an eardrum scissors uses wearing and tearing little, long service life to the consumptive material of production cutter is few, saves resource and cost.

According to the utility model discloses an embodiment, sword outer mouthful 5 sets up in the upper end or the lower extreme of blade 4, then links up by outer mouthful root 7 between sword outer mouthful 5 and the handle of a knife 1.

Specifically, the outer opening 5 of the cutter is connected with the cutter handle 1 through the outer opening root 7, so that the hardness of the cutter can be strengthened, and the strength of the cutter can be improved.

According to an embodiment of the present invention, the outer lip root 7 is a cambered surface.

Specifically, when the outer opening 5 and the cutting edge 6 of the cutter are machined, a milling machine can be used for machining, so that the machining is convenient and fast. The outer opening root 7 is a cambered surface at the moment.

The above-mentioned embodiment is the utility model discloses the implementation of preferred, in addition, the utility model discloses can also realize by other modes, not deviating from the utility model discloses any obvious replacement is all within the protection scope under the prerequisite of design.
