Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b):

referring to fig. 1-2, a nail clipper with replaceable cutting head comprises an upper plate 1, a lower plate 2, a pressing handle 3 and a cutting head 4, wherein a rotating shaft 5 is arranged at the position, close to the side edge, of the upper end surface of the upper plate 1 and is connected with the pressing handle 3, a pressing rod 6 is fixedly connected to the position, close to the rotating shaft, of the lower end surface of the pressing handle 3, the lower end surface of the pressing rod 6 penetrates through a through hole formed in the upper plate 1 and is connected with a pressing plate 7, a first spring 8 is sleeved on the surface of the pressing rod 6, and the bottom end of the first spring 8 is connected with the upper end surface of the upper plate 1; the lower end face of the upper plate 1 is fixedly connected with a lower plate 2, the lower plate 2 is herringbone, one end, far away from the rotating shaft 5, of the lower plate 2 is closed with the upper plate 1 to form a cavity, and a sliding door 9 is arranged at the cavity;

the cutter head is multiple and consists of an upper blade 4-1, a lower blade 4-2 and a second spring 4-3, the upper blade is connected with the lower blade through the second spring, and a convex block 10 is arranged on the lower wall surface of the lower blade at a position corresponding to the second spring.

Preferably, the lower plate 2 is further provided with a groove 11 on the upper wall surface thereof for matching with the protrusion 10.
