Embodiment 1

[0025] Embodiment 1: ultra-thin nail clippers, see Figure 1 to Figure 4 .

[0026] In order to reduce the amount of steel cut by ultra-thin nail clippers during metal processing, the upper jaw (1a) of the nail clipper is bent into a U-shape by section steel and then cold-forged to form the upper jaw, and the lower jaw (2a) is also made of The section steel is cold forged to form the lower jaw, and after drilling, the pin shaft (4a) is used to link the upper jaw (1a) and the lower jaw (2a), the pin shaft (5a) hinges the upper jaw (1a) and the lever (3a), and the roller (7a ) is installed on the rear end of the lower tong (2a) with a pin shaft (6a), the torsion spring (8a) is fixed in the upper tong (1a) by its own elastic force, and the tail end of the lower tong (2a) rests on the torsion spring (8a) On the crosspiece of the rear end, depress the torsion spring (8a) when trimming the nails, and utilize the elastic force of the torsion springs (8a) to reset after trimming the ...

Embodiment 2

[0027] Embodiment 2: universal type nail clipper, see Figure 5 to Figure 8 .

[0028] The general-purpose nail clipper of the present invention is made by sheet metal stamping. The upper tongs (1b) are placed on the lower tongs (2b), hinged with a pin (4b), and the positioning rod (11b) determines the opening of the jaws. Roller (7b) is installed in the rear end of lower jaw (2b) with bearing pin (6b), and the rear end of upper jaw (1b) and the rear end of lever (3b) are hinged with bearing pin (5b). Spring (8b) is fixed by bearing pin (4b), and its elastic force makes jaws open.

Abstract

The invention provides a nail clipper, wherein a two-stage lever is adopted for reinforcement, and the first-stage lever is additionally arranged at the rear end of the upper clipper body. When nailsare trimmed, the force application point of the lever is close to the cutting edge, force is applied gently, holding is comfortable and natural, and the direction can be controlled better. Particularly, the rear lever adopts a tabulated design scheme, so that the thickness of the whole nail clipper during storage is greatly reduced, and the nail clipper is convenient to carry. The jaw of the lowerclipper is of a sunken structure, broken nails can be collected, and splashing is prevented. And the sinking distance of the lower jaw is equal to the thickness of the lever pressing plate. The upperclamp and the lower clamp are arranged in the same layer, and the lower clamp is clamped in an empty position in the middle of the upper clamp. A reset torsion spring is arranged inside the upper clamp, and a roller or a cam is arranged at the rear end of the lower clamp. Various design schemes are provided, and different manufacturing processes can be adopted. The universal nail clipper is manufactured by adopting a stamping process, is suitable for mass production and is low in manufacturing cost.

Description

technical field [0001] The invention relates to a nail clipper for trimming nails, in particular to a nail clipper which adopts a secondary lever to increase force and adds a primary lever to the rear end of the upper clip. There are two kinds of nail clippers widely used in modern times, the pressure plate type and the scissors type. The force point of the two kinds of nail clipper levers is all arranged at the rear end of the nail clipper, far away from the cutting edge, poor alignment, and unstable grip. Background technique [0002] According to the application number US19020134257, although the nail clippers described in the U.S. patent specification of the publication number US741709A have adopted the design scheme of increasing a rear lever, the structure is complicated, the manufacture is difficult, and the use is inconvenient. [0003] According to the application number US20100980820, the U.S. patent specification of the publication number US9204703B2; the applicat...
