[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The invention relates to a brake cable sleeve, wherein the protective mechanism of the device is used to prevent the brake cable from rubbing against the sleeve body. When the brake cable is inserted into the sleeve body, the clamping balls in the sleeve body will press against the brake cable, so that the brake cable keeps a distance from the inner wall of the sleeve body. When the brake cable slides in the sleeve body, the sliding brake cable rubs against the clamping balls, and the clamping balls roll. The rolling clamping balls can reduce the friction degree of the brake cable. At the same time, the rolling clamping balls can apply the lubricating oil in the adhered lubricating layer to the brake cable, further reducing the friction force between the brake cable and the clamping balls. The heat generated by the friction between the clamping balls and the brake cable is dissipated to the outer wall of the sleeve body through the connecting block and the heat dissipation plate, so that the heat generated by the friction can be dissipated in time, thereby reducing the friction degree between the brake cable and the sleeve body, and improving the service life of the brake cable. The invention solves the problem that the brake cable and the sleeve are repeatedly rubbed against the inner wall of the sleeve when in use, and the repeated friction easily causes damage to the brake cable and the sleeve, thereby affecting the use effect of the brake cable.
