[0002] Wire cutters, also known as vise, flat-nose pliers, and comprehensive pliers, are a tool that can cut hard and thin steel wires, making them widely used in various fields such as life and industrial production.

[0003] Wire cutters are composed of a handle and a pliers body. As a commonly used tool, they need to be heat treated during production in order to improve the performance and hardening strength of the pliers body.

[0004] However, currently, when heat-treating the pliers body of wire cutters, the wire cutters to be treated are usually stacked and placed in a container, and then the container is sent to a heating furnace to heat-treat the wire cutters in the container. However, since the wire cutters are stacked and placed in the container, the wire cutters are not evenly heated during heating, thereby reducing the effect of heat treatment on the surface of the wire cutters. In view of this, the present utility model is specially proposed. Utility Model Content
