The pressure plate pin passes through the upper end of the pull nail, which allows the pull nail and the pressure plate to be relatively rotatably connected around the pressure plate pin; a block is fixed on the upper knife body, when the nail is to be cut, the The pressure plate is lifted up and turned around the pull nail hole of the lower knife body and then pressed down, because the front of the pressure plate is facing down at this time, so that the front of the pressure plate is against the cushion block, and the pressure plate uses the cushion block as a supporting point to pass the pull nail Tilt the lower blade up a certain distance to close the edges of the upper blade and the lower blade to realize the nail cutting function; when you want to close the nail clippers, lift up the pressure plate and rotate it around the nail hole of the lower blade body, then lower it Because the back of the pressure plate is facing down, and a first groove is provided on the back of the pressure plate, the cushion block can sink into the first groove, so that the pressure plate can rotate around the pressure plate pin to the bottom and close.

Further, both sides of the pressure plate also include first protrusions, and the upper knife body includes a supporting step. When the pressure plate is lifted, the first protrusion of the pressure plate abuts on the supporting step of the upper knife body, so that When the upper blade and the lower blade are separated and opened, the opening size is controlled.

Further, in the knife body part, a bump is provided at the connection between the upper knife body and the lower knife body. At the same time, an insert block is mounted on the pressure plate so that it can move back and forth. When the pressure plate of the nail clipper is rotated to the end and closed, Push the insert block again, so that the head of the insert block is inserted into the concave-convex block and stuck, so that the pressure plate can no longer spring up naturally.

Further, the above-mentioned insert block is installed in the second groove on the front of the pressure plate, and a spring is installed between it and the pressure plate, so that the head of the insert block can be automatically inserted into the concave and convex portions of the knife body under the action of the spring force. In the block, when a nail clipper is needed, push the insert block with your fingers, so that the head of the insert block exits the concave and convex block of the knife body part.

Further, the lower blade body of the blade part is an elastic plate, one end of which is fixedly connected with the upper blade body, and the other end is the lower blade.

Further, one end of the upper knife body and the lower knife body of the knife body part are fixedly connected, the other end is the upper knife body, and the middle is two connecting beams. The upper knife edge and the lower knife edge are naturally separated under the elastic force of the lower knife body. , The knife edge can be closed only under the action of external force.

Further, the two sides of the upper knife body are two connecting beams, the pressing plate can be recessedly mounted on the upper surface of the upper knife body, and the lower knife body can be recessedly mounted on the lower surface of the upper knife body, so that it acts as a nail clipper. When closed, its shape is a long flat bar.

Further, the pressing plate or the cutter body part is formed by powder metallurgy die casting and sintering or formed by plate processing.

Further, one end of the knife body part is also provided with a pillar or hole for hanging nail clippers.

Further, the back of the pressing plate is provided with a rough surface or polishing pad for nail grinding. When the pressing plate is opened, the rough surface or polishing pad for nail polishing on the pressing plate is exposed, and the nail can be polished.

Beneficial effect

The technical scheme of the present invention has the following beneficial effects: simple structure, durable, the nail clipper blade is in a normally closed state when stowed, the edges and corners are not exposed, and the pressure plate is also embedded in the blade body, making the nail clipper smaller and convenient to carry , The appearance is exquisite.

The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that although the following detailed description and specific examples show preferred embodiments of the present invention, they are merely illustrative and do not imply any impact on the scope of the present invention. limit.
