The invention discloses an electricity-saving type multi-shaft punching mechanism. The electricity-saving type multi-shaft punching mechanism comprises an upper cover plate; a motor fixing plate is fixedly connected to the upper end of the middle of the upper cover plate and provided with a drive motor; a driving gear is arranged on a rotary shaft of the drive motor and is in engaged drive with a drive gear on the upper cover plate. A lower cover plate is connected with the lower end face of the upper cover plate through a guide shaft. A two-stage crankshaft rotary mechanism is arranged between the upper cover plate and the lower cover plate and comprises a vertical power taking-off shaft; the power taking-off shaft is connected with the rotary axis of the drive gear; the lower end of the power taking-off shaft is connected with a transverse first connection rod to form a first-stage force arm; the tail end of the first connection rod is connected with a vertical rocker; the lower end of the rocker is connected with a transverse second connection rod to form a second-stage force arm; the tail end of the second connection rod is connected with a vertical drill bit drive shaft; the tail end of the drill bit drive shaft is connected with a drill bit and drives the drill bit. The multi-stage and multi-shaft drive is formed through the rocker, the utilization rate of the motor is improved, and electricity is saved.
