Claims

[Scope of utility model registration request]

A tool spindle equipped with a collet at its tip for removably holding various tools is rotatably supported on the axis of a spindle holder, and the spindle holder is inserted into the outer case and the end of the tool spindle is The upper end of the spindle holder is connected to the operating shaft via a universal joint, and the upper end of the spindle holder is swingably supported by the outer case via a spherical movement mechanism centered on the axis, and the lower end of the spindle holder is connected to the outer case. The outer ends of the springs are supported in a fixed position by a plurality of springs press-fitted radially from the outer case, and the outer ends of the springs are supported in contact with the tapered surface of the adjuster string screwed into the outer periphery of the outer case. A tool spindle unit characterized in that the elastic force of a spring can be freely adjusted by applying pressure on a tapered surface.
