A variety of hole opening machines are disclosed in the prior art. For example, a steel structure punching device proposed in the Chinese utility model patent with the publication number CN220992530U. The punching device pushes the installation shell upward by the second hydraulic telescopic rod to make the top end of the conveyor belt higher than the top end of the equipment main body.
