Claims

[Scope of utility model registration request]

(1) A detachable ring that is detachably attached to the outer periphery of the output shaft of a portable electric drill device, a plurality of guides connected to the periphery of the detachable ring, and a plurality of guides that are slidably connected and , a plurality of guide rods 1 extending parallel to the axis of the drill, which are clamped in the chuck of the drill device.
It is attached to the tips of the plurality of guide rods to connect and fix each guide rod, has a pressing surface parallel to the plane orthogonal to the guide rods on the front side, and has an opening for insertion of a drill. The device is equipped with a pressing tool that presses the guide away from the pressing tool, and a pressing spring that presses the guide away from the pressing tool. An auxiliary device for perpendicular drilling that is attached to a portable electric drill device configured to perform drilling by being pushed out in the axial direction.

(2) A bar-shaped guide rod is fixed to the pressing tool,
This guide rod is slidably inserted into a cylindrical guide, and a coil spring, which is a compression spring, is built in between the guide and the guide rod. An auxiliary device for perpendicular drilling that is attached to the portable electric drill device described in item (1).

(3) The guide 10 is cylindrical, the guide is slidably built into the guide rod, and a coil spring, which is a compression spring, is built into the guide rod. An auxiliary device for perpendicular drilling that is attached to the portable electric drill device described in item ).

(4) An auxiliary device for perpendicular drilling that is attached to a portable electric drill device as set forth in claim (1) of the utility model registration, in which a groove extending linearly is formed on the pressing surface.
