Claims

[Scope of utility model registration request]

In a structure in which when the tool is attached to the spindle, the tool is sieved by a pull-up screw inserted into the spindle and driven by a drive key, the tool is rotatably provided at the hole end of the spindle and rotationally connected to the pull-up screw. Then, a first connecting cylinder which is movable relative to the pulling screw in the axial direction and further has teeth for rotational connection at its end, and a first connecting cylinder which is slidable in the axial direction on the output shaft of the driving device of the lifting screw. a second connecting cylinder that is rotatably connected and has teeth that mesh with the teeth of the first connecting cylinder; and axially biasing the second connecting cylinder to position the second connecting cylinder in a position where the teeth mesh with the teeth. a spring member, an external toothed member attached to the end of the main shaft, and a cylindrical body that is concentric with the main shaft and can slide in the axial direction through an internal toothed part that meshes with the external toothed member at the tool mounting position; a spring member for returning the cylindrical body to the meshing position when it is disengaged from the meshing position; and a spring member provided on the end face of the cylindrical body so that when the main shaft is moved to the tool attachment/detachment position, the external tooth member is not in the meshing position and the cylinder is Driving a tool pulling device characterized by comprising: an intermediate ring that moves in the axial direction so that when the body is moved in the axial direction, the intermediate ring comes into contact with the second connecting cylinder and disengages the teeth of the second connecting cylinder. mechanism.
