Electric wire pliers for aerial work

Abstract

The invention discloses a wire clamp for aloft work. The wire clamp structurally comprises a clamp mouth, grips, a limiting block and a ring-cutting mechanism. The clamp mouth is fixedly connected with the grips in an embedded manner. The limiting block is movably clamped to the clamp mouth. The ring-cutting mechanism and the clamp mouth are of an integrated structure. The outer skin of a multi-strand rubber insulated wire can penetrate through an accommodating groove in the ring cutting mechanism, a worker slightly swings the grips, therefore, a sliding block on a peeling mechanism can carryout ring cutting on the rubber insulation skin, and the situation in which the inner core is easy to partially break in the pulling process due to repeated pulling during peeling of the multi-strand rubber insulated wires is avoided. A cutting ring on a piercing head can be matched with a shell to peel the aged and hardened rubber insulation skin, and a cutting piece on the cutting ring can cut the aged rubber insulation skin through extrusion force generated on the cutting ring when the shell pierces into the aged rubber insulation skin.

Description

technical field [0001] The invention relates to the field of high-altitude operations, in particular to an electric wire pliers for high-altitude operations. Background technique [0002] Wire pliers for high-altitude work are mainly used for cutting and peeling high-altitude wires. By manually pressing the handle, the top jaw can cut and peel the wires. It is widely used in electric power construction and other industries. Based on the above description The inventors found that the existing a kind of high-altitude electric wire pliers mainly has the following deficiencies, for example: [0003] Since the inner core of the multi-strand rubber insulated wire is composed of multiple thinner copper wires, and the outer rubber insulation is so tough that the electric wire pliers for aerial work need to pull repeatedly on the surface when peeling it, resulting in The inner core of the multi-strand rubber insulated wire is prone to partial fracture during pulling, thereby affecti...
