In a petrol engine, springs keep the valves closed. If you want to work on those valves, you have to keep the spring compressed. To have the hands free, one uses valve spring pliers. Her jaws are forked to fit on the stem of the valve. The mouth opens when you press on the arms. In some models, the jaws always remain parallel to each other. A rack and hook prevent it from closing. Valve spring pliers are to be distinguised from battery clamp pliers. [MOT]

With parallel pliers you can clamp flat metal or metal wire without damaging it. The jaws always remain parallel so that even with thick material all the force is distributed over the entire jaw. The teeth are flat on the material. Springs are fitted in the legs to open the pliers. Some pliers are equipped with a wire cutter. [MOT]
