Cutting plier and cutting plier head

A cutting plier head, comprising a first cutting part and a second cutting part which are hinged with each other, the second cutting part having a gap which is not zero from at least part of the first cutting part and the second cutting part cooperating with the first cutting part to realize a cutting function;

• wherein the first cutting part and the second cutting part are provided with a non-cutting edge and a partially extending blade opposite to each other, the non-cutting edge is different from the partially extending blade to prevent damage during cutting, and the non-cutting edge and the partially extending blade cooperate with each other to realize the cutting function;
• the second cutting part is provided with the partially extending blade, the partially extending blade protrudes toward the first cutting part;
• wherein a side of the second cutting part provided with the partially extending blade proximate to the non-cutting edge is provided with a groove, and a gap between the first cutting part and the second cutting part at a position where the groove is provided is not zero;
• wherein the partially extending blade is arranged on a side of the groove away from the cutting plier body;
• wherein the groove is formed by the protrusion of the partially extending blade toward the first cutting part, the partially extending blade protrudes beyond a base of an adjacent part of the groove, and the adjacent part is positioned adjacent to the partially extending blade.

A cutting plier, comprising:

• a cutting plier body comprising a left handle and a right handle which are hinged with each other
• a first cutting part;
• a second cutting part, the second cutting part having a gap which is not zero from at least part of the first cutting part and the second cutting part cooperating with the first cutting part to realize a cutting function;
• and
• a hinge member through which one end of the first cutting part is connected with the right handle and through which one end of the second cutting part is connected with the left handle through a hinge member;
• a gap between the first cutting part and the second cutting part is adjusted by controlling the left handle and the right handle;
• wherein the left handle comprises a left handle body and a left connecting member, one end of the left handle body being provided with a left connecting member;
• and the right handle comprises a right handle body and a right connecting member, one end of the right handle being provided with a right connecting member, the left connecting member and the right connecting member being connected by a pivot on which a spring is sleeved;
• wherein the left connecting member comprises two oppositely arranged left plier pieces, two ends of which are respectively connected by fasteners;
• and the right connecting member includes two oppositely arranged right plier pieces, two ends of which are respectively connected by fasteners, and middle ends of the two left plier pieces are connected with middle ends of the two right plier pieces by the pivot;
• wherein the hinge member comprises a left hinge piece and a right hinge piece, one end of the left hinge piece being connected with the first cutting part, the other end of the left hinge piece being connected with one of two ends of the two left connecting members;
• one end of the right hinge piece being connected with the second cutting part, the other end of the right hinge piece being connected with one of two ends of the two right connecting members;
• the other one of two ends of the two left connecting members is connected with an end of the right hinge piece, and the other one of two ends of the two right connecting members is connected with an end of the left hinge piece.
