[0015] Beneficial effects:

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The utility model uses a spring to push the slider inside the second fixed clamp to move upward along the first limiting groove and the second limiting groove, thereby adapting to lines of different diameters and ensuring that the fixed clamp is tightly attached to the surface of the line. There is no need to prepare insulating sheaths for lines of different diameters, which reduces the time for selecting products suitable for the line. In addition, it greatly reduces warehouse pressure and management costs, so that the product has the advantages of reduced inventory pressure and high adaptability.

[0018] (2) In the present invention, when the line insulation sleeve is displaced, the force exerted by the spring causes the fixed clamp to be pressed against the surface of the line, so that the top of the first inclined groove is pressed against the surface of the line. Similarly, the top of the second inclined groove is also pressed against the surface of the line, increasing the friction between the line insulation sleeve and the line. The first inclined groove and the second inclined groove are in opposite directions, and the displacement amount causes the slider in the second fixed clamp to displace, cooperating with the first limiting groove and the second limiting groove, so that the distance between the first inclined groove and the second inclined groove is shortened, thereby increasing the force of biting the line and making the product have the advantage of anti-slip.
