Abstract
The invention discloses a tip diameter measurement meter. The tip diameter measurement meter comprises a rotating disc. A shaft hole is formed in the circle center of the rotating disc. A rotating shaft connected with the shaft hole through a key is arranged in the shaft hole. Helical-line-shaped threads are formed in the outer lateral surface of the rotating disc and provided with three clamping rods, wherein the clamping rods are meshed and matched with the helical-line-shaped threads. An annular shell coaxial with the rotating disc is arranged outside the rotating disc and provided with a hole groove, wherein the hole groove is in clearance fit with the tail portion of the clamping rod in a pulling and drawing mode. The other side of the shell extends outwards to additionally serve as a connecting sleeve of a handle, wherein a rotating shaft hole is formed in the axial direction inside the connecting sleeve, the rotating shaft penetrates through the rotating shaft hole and is matched with the shaft hole in a rotating mode, a reading groove is formed in one side of the connecting sleeve, and the portion, inserted into the rotating shaft hole, of the rotating shaft is provided with external threads.
