Claims

[Scope of utility model registration request]

A holder main shaft that is directly connected to the shaft drive shaft and has an internal gear and a planetary gear, a sun gear that meshes with the planetary gear at one end, and a rotary tool at the other end that rotates with the holder main shaft. It consists of a tool holding shaft with the same center,
The tool holding shaft is fixed to the holder main shaft, and its outer diameter surface is a cylindrical surface concentric with the center of rotation, and its inner diameter surface is an eccentric surface. The radial surface (the inner diameter surface is the same eccentric surface as the eccentric inner diameter surface of the outer cylinder, and the inner diameter surface is a cylindrical surface concentric with the center of rotation. An eccentric amount adjustment guide groove extending approximately 180 degrees is formed at the boundary of the eccentric surface, and an axial movement prevention member is inserted into the guide groove from the eccentric outer cylinder side via a locking screw, so that the rotational direction is fixed on the fixed eccentric outer cylinder side. A rotary tool holder characterized by being provided with a screw.
