[0031] like Figures 1-4 As shown, when using the clip unit 5, since the base 51 and the movable cover 52 are movably connected by a pivot, when clipping the cable through the clip unit 5, the movable cover 52 is folded upwards, the cable is placed inside the base 51, the movable cover 52 is reset, and the hooks at one end of the base 51 and the movable cover 52 are interlocked, fixing the base 51 and the movable cover 52 while clipping the cable. Then, while pulling the zipper head 4, the cable clipped on the clip unit 5 can be pulled to the ohm clip 2. In this embodiment, the ohm clip 2 is not provided at the zipper teeth 3 at the bottom of the cable tube body 1. The shape of the ohm clip 2 is similar to the Ω symbol, and the opening space at one end is smaller than the middle part. The cable is pressed in through the opening at one end of the ohm clip 2. The middle part of the ohm clip 2 is used to wrap the cable. The ohm clip 2 can firmly fix the cable and provide good protection. After the cable is clamped by the ohm clip 2, the zipper head 4 is then reset to complete the pulling operation, simplifying the operation steps of pulling the cable and improving work efficiency.

[0032] Wherein the cable clamp can also use the wire clip 6, the wire clip 6 is made of plastic material, can ensure that it has elasticity, and the opening space of one end is smaller than the middle part, after the cable is pressed into the upper end opening, the clamping teeth of both ends can also ensure the stability of the cable.
