Claims

[Scope of utility model registration request]

An annular heating element attached with its center aligned with the through hole of the tip holding frame, a head that is inserted into the inner hole of the annular heating element at its tip, and a rear part of the annular heating element is inserted into the through hole. a first spring that biases the striking rod rearward from the tip holding frame; and a cylindrical excitation member fixed to the rear end of the tip holding frame with its center aligned with the through hole. a coil, an actuator that is inserted into a hollow part of the excitation coil and slides toward the rear end by electromagnetic force when the excitation coil is magnetized; a second spring having a larger elasticity than the first spring to force the tip of the movement element into pressure contact with the rear end of the striking rod; and outputting a DC intermittent signal at a predetermined pulse interval to the excitation coil. A hammering pine surge device comprising a control circuit that causes the head of a hammering rod to intermittently protrude from a tip holding frame.
