Claims

[Scope of utility model registration request]

In a hole-punch unit, the base arm is pivoted on the support and the base arm is parallel to the base arm, which is pivoted on the support for setting the work panel to the welding jig. A floating C-type punch arm is provided with a balance spring interposed between the base arms, and the floating C-type punch arm slides on the shaft.
A cylinder is installed at the upper end of the die punch arm, through which a cylinder rod with a punch and a die formed at the lower end is pushed in and out, and is engaged with a floating pin formed on the cylinder rod that changes the operation between the die and punch. An eco-rise type hole punch characterized by a stopper provided on the base arm.
