Since the bearing mounting sleeve 2 is provided and the bearing mounting sleeve 2 extends along its axial direction, the bearing mounting sleeve 2 has a certain length, thereby changing the force point and force strength of the transmission mechanism 4 located inside the bearing mounting sleeve 2, which can not only enhance the radial force strength of the transmission mechanism 4, but also make the transmission mechanism 4 evenly stressed, effectively ensuring that the transmission mechanism 4 is not prone to breakage and reducing wear, and one side of the dust cover 3 is provided with a size matching the size of the bearing mounting sleeve 2. The dust cover 3 is fixed to the upper surface of the base 1 by a screw, and the mounting groove 31 on one side of the dust cover 3 contacts the side wall of the bearing mounting sleeve 2. By opening a mounting groove 31 on one side of the dust cover 3 that is adapted to the size of the bearing mounting sleeve 2, the dust cover 3 is assembled at the upper end of the base 1, and the mounting groove 31 on the side of the dust cover 3 contacts the side wall of the bearing mounting sleeve 2, so that there is no matching and contact relationship between the bearing mounting sleeve 2 and the transmission mechanism 4, thereby preventing the wear of the dust cover 3 hole and the breakage of the dust cover 3 and the mounting screw of the base 1 after the transmission mechanism 4 is broken or worn, effectively reducing the maintenance frequency and maintenance cost, and improving the production efficiency.
