Claims

[Scope of utility model registration request]

(1) A cylindrical first adapter that has a socket portion at one end that has an axial center hole and an elongated hole that penetrates perpendicularly to the axis, and is attached to the spindle of a processing machine at the other end; It is detachably held, and has a shaft portion at the other end that is inserted into the center hole of the first adapter with a certain gap, and this shaft portion has a small axial length (both at two locations). a second adapter having an elastic buffer member on its outer periphery that maintains a constant clearance with respect to the center hole, and a pin hole drilled in a direction perpendicular to the axis; the shaft portion of the second adapter is inserted into the center hole of the first adapter; However, by driving from the elongated hole of the socket part into the pin hole of the shaft part, relative movement of the second adapter in the axial direction with respect to the first adapter is allowed, but relative movement in the rotational direction is allowed. A tool holder, characterized in that the tool holder is a biasing means that biases the pin member that does not allow the user to move the second adapter away from the first adapter.

(2) The biasing means includes a sleeve member that is fitted over the first adapter and has one end abutting the second adapter, and a spring member that biases the sleeve member toward the second adapter. A tool holder according to claim 1 of the utility model registration claim.
