Claims

[Scope of utility model registration request]

The main body, which has a connection part for the machine tool at one end, is provided with an insertion hole for inserting a shank having an opening in the end face of the other end, and the other end of the main body is provided with an insertion hole for inserting a shank inserted into the insertion hole. A fastener for tightening and fixing is provided, and a receiver for receiving the rear end of the shank is provided in the insertion hole, and the arrangement state is such that the receiver can be rotated. In the tool holder, the male thread formed on the outer circumferential surface of the holder is screwed into the female thread formed on the inner circumferential surface of the insertion hole so that the tool holder can be moved forward and backward in the axial direction of the insertion hole. Inside the hole is a first gear whose rotational axis is aligned with the rotational axis of the receiver;
a second gear whose rotational axis intersects with the rotational axis of the receiver and meshes with the first gear;
The first gear is connected to the receiver so that rotational force can be transmitted thereto, and the second gear is configured such that the second gear can be rotated from the side of the main body.
A tool holder comprising an operating portion exposed in a through hole provided in a part of the peripheral wall of the insertion hole in the main body.
