PURPOSE:To readily and firmly perform the automatic clamp and unclamp of the blade section of a cutting tool by clamping or unclamping the blade section equipped with a cutting tool by an L-shaped clamp lever. CONSTITUTION:The end section of a clamp lever 16 is inserted into the through hole 12 of a blade section 2 and placed on a base 5. The rotation of a screw 14 to the direction of 22a lowers the screw 14 toward 23a. As a result, the crank lever 16 engaged with a small diameter section 15 is swung to push the convex section 11 of the blade section 2 to a concave section 6 making a shank section 1 clamp the blade section. The rotation of the screw 14 to the direction of 22b release the clamp of the blade section 2. The blade section 2 can, thus, be automatically clamped and unclamped. |
