What is the definition of high leverage combination pliers?

High leverage combination pliers are hand tools used for clamping and holding machined workpieces or for twisting, bending and cutting wires. The shape of the pliers is V-shaped and usually consists of three parts: handle, jaw and mouth.

What is the definition of high leverage combination pliers?

There are many types of high leverage combination pliers and they have a wide range of applications. It is an indispensable hand tool for pinching and shearing workpieces in various industries such as assembly, repair and installation. But it has a common basic structure, that is, each hand plier consists of three parts: a plier head, a pin and a plier handle. The basic principle of the high leverage combi pliers is to use two levers at one point in the middle and connect them crosswise with pins so that the two ends can move relative to each other. As long as the rear end is operated by hand, the other end can clamp the object. In order to reduce the effort of the user during operation, according to the lever principle in the mechanics, the plier handle is usually carried out longer than the plier head, so that with less force a stronger clamping force can be achieved according to the requirements of benefit.

What are the main components and how do the high leverage combination pliers work?

The main component of the high leverage combination pliers is a pair of handles. Ergonomically designed pliers handle for a secure and comfortable grip. Fixing axis, this is the fixing axis of the pliers. The connection point must be movable smoothly and without backlash so that the pliers can be easily opened or closed with one hand. It converts a small external force (e.g. the hand force applied to the pliers arm) into a large working force, so that the pliers can be clamped or cut effectively. As the external force applied to the pliers arm increases with the lever ratio, the high leverage combination pliers’ mouth generates an external force that captures the movement. If a large external force is to be generated, the distance from the center of the rivet position of the pliers to the handle must be as large as possible and the distance from the clamping or cutting opening to the rivet center must be as short as possible. However, many pliers do not greatly increase the hand force, as they only facilitate working in difficult places, such as when assembling electronic devices and in applications in electronics and precision mechanics.
