Description

Tool pliers for kneading ring

Technical Field

The utility model belongs to the technical field of the electrical wiring construction, concretely relates to hold between fingers annular and use instrument pincers.

Background

In the construction process of electric wiring, a plurality of core wire joints need to be sleeved on a binding post in a pinching mode, then annular core wire joints are connected with other core wire joints, at present, the core wire joints are manually pinched according to the thickness of the binding post, and due to the fact that the core wire joints are pinched manually, the sizes are not standard, and the efficiency is low; when the annular core wire joint is too large, the sleeve is pressed open by a screw on the binding post to cause poor contact, and when the annular core wire joint is too small, the binding post cannot be sleeved; therefore, the wiring period is increased, and the joint may have a contact failure.

In addition to the above-mentioned wire harness construction process, the metal wire pinching ring processing process of some ornaments is also by hand pinching ring.

Generally, the annular core wire joints or metal rings pinched by the manual pinching manner are not of the same size and are inefficient.
