Two limiting rings 102 are integrally formed on the surface of the shaft tube 1, and the limiting ring 102 is against the surface of one end of the inner ring of the bearing 5. By installing the bearing 5, the conductive voltage roller 2 can rotate more smoothly, and the limiting ring 102 is set on the shaft tube 1 to limit the position of the bearing 5 to prevent the bearing 5 from being displaced due to long-term rotation.

[0024] The other end surface of the inner ring of the bearing 5 is abutted with a spring buckle 6, which is clamped in the clamping ring groove 103 on the surface of the shaft tube 1. By clamping the spring buckle 6 on the shaft tube 1, the position of the bearing 5 is further fixed.
