Embodiment one:
as shown in fig. 1 to 6, the present embodiment provides a nail clipper head, comprising: the nail cutter comprises a shell 1 and a cutter 2, wherein the cutter 2 is positioned inside the shell 1 and is in rotary connection with the shell 1, the shell 1 is provided with a nail hole 10, the inner wall of the nail hole 10 is provided with a guide surface 101 and a step surface 102, and the step surface 102 is positioned between the guide surface 101 and the cutter 2.
On the basis of the technical scheme, one end of the step surface 102 far away from the cutter 2 extends outwards, the guide surface 101 is connected with the step surface 102, and the cross section area of the step surface 102 is smaller than or equal to the cross section area of the guide surface 101 at the joint of the guide surface 101 and the step surface 102. The cross-sectional area is a cross-sectional area taken by a plane parallel to the transverse plane, and the cross-section, the longitudinal section, and the horizontal plane in fig. 1 to 3 are reference planes.
On the basis of the technical scheme, the step surface 102 is perpendicular to the transverse surface.
On the basis of the technical scheme, the guide surface 101 is a round angle or a chamfer angle.
On the basis of the technical scheme, the nail hole 10 is arc-shaped. The arc mimics the arc of a nail.
On the basis of the technical proposal, the cutter 2 is provided with a cutter edge 21 at the outer side, and the helix angle of the cutter edge 21 is 25.5 degrees to 30.5 degrees.
On the basis of the technical scheme, the helix angle of the blade 21 is 27.5 degrees.
On the basis of the above technical solution, the number of the blades 21 is 7 to 9.
Preferably, the number of the blades 21 is 8.
On the basis of the technical scheme, the cutter further comprises a bearing 3, a first shaft 22 and a second shaft 23 are respectively formed at two ends of the cutter 2, and the first shaft 22 and the second shaft 23 are respectively connected with the shell 1 in a rotating mode through the bearing 3.
On the basis of the technical scheme, the shell 1 is respectively provided with a groove 11 and chip removal holes 12 at the front side and the rear side far away from the nail hole 10, and the nail hole 10 is formed at the bottom of the groove 11.
Based on the above technical solution, the width of the step surface 102 is 0.2 mm to 0.4 mm. The width is the length of the step surface 102 in the longitudinal direction (front-rear direction).
On the basis of the technical scheme, the width of the step surface 102 is larger than or equal to the width of the guide surface 101. The width is the length of the step surface 102 and the guide surface 101 in the longitudinal direction (front-rear direction).
Working principle:
the motor drives the first shaft 22 to rotate and the user extends the bracket into the nail hole 10. The rotating blade 21 contacts the nail to trim the nail, and the trimmed nail scraps are discharged from the casing 1 through the scraps discharging hole 12.
The slope of the blade 21 is 27.5 degrees and the increased slope (helix angle) results in sharper cutting. The principle is that when the nail is cut in the groove between the blades 21, the blades 21 are rotated from the oblique upper direction to the oblique lower direction to cut the nail, after the inclination is increased, the area of the blades 21 contacted with the nail is small when the nail is cut, thereby reducing the resistance, and the cutting speed can be increased. At the same time, the number of blades 21 is changed from 10 blades to 8 blades in the prior art, because the distance between 2 blades 21 is reduced after the inclination is increased, the number of nails which can be inserted is reduced, and thus the cutting speed is reduced.
The curved nail hole 10 and reduced number of blades 21 allow more extension during nail trimming. And the nails can ride on the reserved step surface 102, so that vibration of the nails during trimming can be reduced. Since vibration of the nails is reduced, the number of nail scraps ejected from the nail holes 10 due to vibration is also reduced when the nails are trimmed, and flying scraps can be effectively reduced.
The present utility model has been described above by way of example, but the present utility model is not limited to the above-described embodiments, and any modifications or variations based on the present utility model fall within the scope of the present utility model.
