置。This is a device that removably attaches a rod such as a metal rod to the tip of a hole drilling machine via a connecting fitting, and at the rear of the rod,
A notch groove is formed in the direction perpendicular to the axis, and an insertion hole into which the rear part of the rod can be fitted is formed in the connecting metal fitting, and the connecting metal fitting has a
A retaining member that can be engaged with the notch groove of the rod from a direction perpendicular to the axis, and an elastic member that biases the retaining member in the engagement direction are provided. A torque transmission surface contacts the bottom surface of the notch groove of the rod during rotation and transmits the rotational torque of the drilling machine to the rod, and a torque transmission surface contacts the bottom surface of the notch groove of the rod and resists the above elastic member when the connecting fitting rotates in reverse. An engagement release surface is formed to move the retaining member in the engagement release direction, and between the side surface of the retaining member and the notch groove of the rod, the rear end surface of the rod is aligned with the bottom surface of the insertion hole of the connecting fitting. A connecting device for rods in a taphole drilling machine, characterized in that the rods are configured to form a gap when they are in contact with each other.
