Claims

[Scope of utility model registration request]

It consists of a magnet with a magnetic coil wound around an iron core, a stand attached to the top of the magnet, and an electric drill attached to the stand so that it can move up and down, and the stand has a feed motor, a reduction unit, and a handle. It consists of a clutch part that switches between automatic feed and manual feed of the electric drill by axial movement of the shaft, a high-speed specific reduction gear is used as a part of the reduction part, and a gear is attached to the input side of the high-speed specific reduction gear. , an automatic magnetic drilling machine equipped with an automatic feed mechanism in which one of the clutches is attached to the output side, and the handle shaft passes through and supports the gear and the clutch, the high-speed specific reduction device is connected to the input side and the output side. A one-way clutch is installed on the inner diameter of the gear on the input side so that the handle shaft rotates idly relative to the gear during feeding, and locks the handle shaft and rotates simultaneously when returning. The solenoid coil, plunger, and link mechanism are arranged so that one of the components of the high-speed specific reduction gear is fixed during feeding and freely rotatable during return by opening and closing the solenoid coil. This is a quick return mechanism for an automatic magnetic drilling machine in which a switch is installed in one of the components of the high reduction ratio device to detect whether it is fixed or not.
