[0002] According to the authorization announcement number CN215928301U, a high-precision gear is disclosed, including a circular ring, a gear is integrally formed on the rear end face of the circular ring, and a tightening mechanism is installed on both the upper and lower sides of the front of the gear, and the tightening mechanism includes a straight plate, a screw, a ball and a handle, the rear end face of the straight plate is welded to the front of the gear, and the inner wall of the straight plate is threadedly connected to the outer wall of the screw. In this high-precision gear, the rotating screw drives the ball to move outward until the outer side of the ball is tightly pressed against the inner wall of the inserted plug ring, which improves stability, avoids vibration separation, and ensures normal use. The circular groove and the plug ring form a wrapped plug-in connection, and the inside and outside form protection to prevent deformation due to long-term use, which is convenient to use and prolongs the service life. The rear end face of the horizontal plate fits with the front of the gear, and then the bolt passes through the horizontal plate and is threadedly connected to the front of the gear to complete the installation of the sleeve, realize connection protection, prevent wear, and facilitate popularization and use.

[0003] A Chinese patent discloses a high-precision gear (authorization announcement number CN219452809U).
