Abstract

This utility model relates to a clamping pliers suitable for on-site polyurethane foaming, belonging to the technical field of on-site polyurethane foaming equipment. The clamping pliers include a support spring, a main clamping jaw, a secondary clamping jaw, a fixed handle, a movable handle, a locking arm, and an unlocking arm. The main clamping jaw is fixedly mounted on the upper end of the fixed handle. The secondary clamping jaw is located on one side of the main clamping jaw. A rotating lug is located at the bottom of the secondary clamping jaw. One end of the rotating lug is hinged to the fixed handle via a rotating pin A. The other end of the rotating lug is hinged to the movable handle via a rotating pin B. The rotating lug and the fixed handle are connected to each other by the support spring. This clamping pliers solves the problem of inconvenient operation when using existing clamps in the on-site polyurethane foaming process, and is particularly suitable for on-site polyurethane foaming applications.
