The cross-sectional shape of the punch head can be arbitrary, and the pressure plate and the hole seat are provided with holes that match the shape of the punch head. When the handle is held, the punch head can pass through the pressure plate and the hole seat, and complete the punching action by impacting the pressure plate and the hole seat. This design is very convenient to use, labor-saving and efficient.

[0003] Existing hole punchers are mainly used to punch holes in non-metallic materials, such as paper, belts and other items, and holes can be punched as needed. The hole punchers commonly seen on the market currently also mostly adopt a pliers-like structure, usually consisting of two pliers and two pliers, which are directly connected together by rivets or hinges. A hole head for punching is installed on one of the pliers, and a gasket or anvil is set on the other side to play a supporting and cushioning role. When the hole puncher needs to be used, just put the object to be punched between the two pliers, apply pressure to close the two pliers, and the hole head will pass through the object to form a preset hole on the object.
