Detailed Description

The following describes the cable scissors of the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, a cable shear with high-strength cutting edges comprises a left blade 1 and a right blade 2 which are mutually crossed and hinged on a hinge shaft 3, wherein the rear ends of the left blade 1 and the right blade 2 are respectively connected with a right handle 4 and a left handle 5, the front opposite sides of the left blade 1 and the right blade 2 are respectively symmetrically provided with a left cutting edge 6 and a right cutting edge 7, the cutting edges of the opposite sides of the left cutting edge 6 and the right cutting edge 7 are respectively composed of a first cutting edge 8 and a second cutting edge 9 which are connected, and the two first cutting edges 8 are respectively positioned at the opposite inner sides of the left cutting edge 6 and the right cutting edge 7; left side cutting edge 6 and right-hand member cutting edge 7 are all divided into straight section and arc section from the past to the back, and the angle alpha that the first blade 8 that is located the straight section formed with the tangent medial surface of left cutting edge 6 or right-hand member cutting edge 7 is 75 ~ 86, and the angle beta that first blade 8 that is located the straight section and second blade 9 formed is 135 ~ 150, and the width of first blade 8 is 1 ~ 1.2 mm.

The cable shears have the advantages that the width of the first cutting edge 8 is increased, the inclination angle between the first cutting edge and the inner side face of the cutting edge is also increased, the strength of the first cutting edge is enhanced, and the cutting edge cannot be abraded by a copper wire when a cable is sheared; and the cable cutter can be used for cutting metal wires such as steel wire ropes.

As shown in fig. 3, preferably, the front ends of the right handle 4 and the left handle 5 are provided with corresponding limiting protrusions 10 on opposite sides. When the cable is cut on, the limiting bulge 10 can enable the left blade 1 and the right blade 2 to be completely closed, but the cable cannot be excessively rotated to be clamped.

Preferably, the limiting protrusion 10 is wrapped by a rubber pad 11. The rubber pad 11 can better protect the limiting protrusion 10, and the right handle 4 and the left handle 5 do not make collision sound when being closed.

As shown in fig. 4, preferably, through holes 12 are opened at corresponding positions on the right handle 4 and the left handle 5, and a magic tape 13 is disposed in the two through holes 12. When the cable scissors are not used, the magic tape 13 can be tied after sequentially penetrating through the two through holes 12, so that the cable scissors are convenient to carry. When using the cable to cut, tear magic subsides ribbon 13, make it break away from in a through-hole 12, then prick magic subsides ribbon 13 in a through-hole 12, do not influence the normal use of cable scissors, magic subsides ribbon 13 is also difficult for losing.

The magic tape 13 may be replaced by a rope, a lock catch, etc.

Preferably, the rear parts of the right handle 4 and the left handle 5 are provided with hanging holes 14. The cable scissors can be hung on the hook through the hanging holes 14, and the cable scissors are convenient to store.

The embodiments of the present invention have been described in detail, and to those skilled in the art, according to the idea of the embodiments of the present invention, there are changes in the specific implementation and application range, and in summary, the content of the present specification should not be understood as the limitation of the present invention.
