Claims

[Scope of utility model registration request]

A gripped part is provided on the proximal end, a rotation device that rotates around its central axis is provided on the gripped part, and a rotation device is provided on the distal end that rotates coaxially with the gripped part and via the rotation device. A rotating stylus fin is provided, and the rotating device and the stylus fin are connected by a substantially U-shaped arm eccentric from the central axis, and the arm has a contact surface with the workpiece, and the contact surface The shape is characterized by being formed into a curved surface such that when the contact surface contacts the workpiece due to horizontal or vertical movement of the stylus, the line of action of the contact force passes outside the central axis. Measuring stylus.
