Claims

[Claim for Utility Model Registration] A tool mounting attachment is provided with a tapered protruding shaft portion that fits into a tapered hole in the tool mounting portion on the machine tool side, and a threaded portion that protrudes from the protruding shaft portion. A rotating body having a threaded portion that is threadedly engaged with the threaded portion of the engaging shaft is installed inside the tool mounting portion, and the rotating body is driven to connect the threaded portions to each other. A tool clamping device comprising a rotary drive means for drawing a tool mounting attachment inward through the tool clamping device. The tool mounting attachment includes a tool drive shaft passing through the engagement shaft portion, and the tool mounting portion includes a clutch mechanism that passes through the rotating body and can be freely connected to and detached from the tool drive shaft on the attachment side. 2. The clamping device according to item 1, wherein the clamping device has a driving main shaft built-in.
