Claims

[Scope of utility model registration request]

A shaft is driven by a motor and is supported on a shaft so that it can move forward and backward, and a drill attached to the tip of this shaft is mounted using a chuck, a swinging body whose central part is supported by a pin, and the rotation of this swinging body moves the shaft. a connecting member that connects the tip of the rocking body and the shaft member so as to move the rocker forward and backward; a tapered edge that is connected to the east end of the rocker and gradually increases the amount of advance of the shaft member; A drilling machine consisting of a cam and a recess provided to intermittently move the shaft back a required number of times.
