Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pliers, in particular to a pair of pressure-adjustable pressure-head pliers. Background Art
[0002] Pliers are a kind of hand tool used to clamp, fix the workpiece or twist, bend and cut the metal wire. The pliers are V-shaped and usually include three parts: handle, jaws and jaws. Pliers are generally made of carbon structural steel. They are first forged and rolled into the shape of pliers blanks, then go through metal cutting processes such as grinding, milling and polishing, and finally heat treated. In the installation process of photovoltaic modules, the plugging of MC4 connectors is an important process. Pliers are usually required for plugging MC4 connectors. A clamping block for clamping MC4 connectors is fixed on the jaws of the pliers. The clamping block is provided with a U-shaped opening for the MC4 connector connecting wire to pass through. Since the size of the U-shaped opening is fixed, the scope of application is limited. Therefore, a pressure head pliers with adjustable pressure is proposed to facilitate adjustment and increase the scope of application. Utility Model Content
