But when it is necessary to cut out paper with beautiful ripples on the edge, it is very time-consuming and labor-intensive
Therefore, lace scissors emerged as the times require, but in the process of use, it was found that the existing lace scissors only had one set of blades and could only cut out one style of lace. Shaped lace shears, which causes an increase in the cost of use, and also makes the number of tools difficult to manage

Embodiment Construction

[0031] refer to figure 1 and figure 2 As shown, a cutting head of the present invention includes a knife seat 1, and a rotating shaft 2 is provided at one end of the knife seat 1, and the rotating shaft 2 is connected to the operating handle. The knife seat 1 is provided with 2 to 6 groups along the circumference for cutting The tooth-shaped blades 3 of the lace, and each group of tooth-shaped blades 3 are arranged along the axial direction of the knife seat 1 . Further preferably, the number of the toothed blades 3 is 3 to 6 groups, the cross section of the knife seat 1 is a regular polygon, and the number of sides of the polygon is 3 to 6 sides; each group of toothed blades 3 is correspondingly arranged on The angle between the two adjacent sides of the knife seat 1. In this embodiment, the knife seat 1 is an equilateral triangle, and the toothed blades 3 are in three groups. The three sides of the knife seat 1 are perpendicular to each other; and the tooth shapes of the...

Abstract

The invention discloses a pair of scissor heads and a pair of craft scissors with the scissor heads, and belongs to the technical field of craft scissors. The pair of craft scissors is characterized by comprising two operating handles hinged together, installation holes are formed in the two operating handles, and the two scissor heads are inserted into the two installation holes respectively. Each scissor head comprises a tool apron, a rotary shaft is arranged at one end of each tool apron and connected with the corresponding operating handle, each tool apron is a regular triangular cone, three sets of toothed blades used for scissoring lace are arranged in the circumferential direction of each tool apron, and each set of toothed blades are arranged in the axial direction of the corresponding tool apron. The toothed blades on the two scissor heads are matched in a one-to-one corresponding mode. A disengagement preventing mechanism used for fixing the scissor heads and a positioning mechanism used for limiting rotation of the scissor heads are arranged on each operating handle on the side of the corresponding installation hole, wherein the disengagement preventing mechanism and the positioning mechanism are matched with the rotary shafts. The pair of scissor heads and the craft scissors with the scissor heads are compact in structure, and flexible and convenient to use, and are used for scissoring the lace.

Description

technical field [0001] The present invention relates to a cutting head, in particular to a cutting head for lace cutters. The present invention also relates to the lace shears using the above-mentioned cutting head. Background technique [0002] In daily life or in study and work, people often use scissors to cut paper, so that the edge of the paper cut out is smooth. But when it is necessary to cut out paper with beautiful ripples on the edge, it is very time-consuming and labor-intensive. Therefore, lace scissors emerged at the historic moment, but in the process of use, it was found that the existing lace scissors had only one set of blades and could only cut out one style of lace. Shaped lace shears, which cause an increase in the cost of use, and also make the number of tools difficult to manage. Contents of the invention [0003] The object of the present invention is to provide a cutting head with reasonable structure and flexible and convenient use to solve the ...
