Abstract

The invention belongs to the field of packaging tying part, and particularly relates to a cable tie. The cable tie comprises a strip body and a clamping hole part arranged at rear of the strip body and used for forming a one-way locking with front of the strip body, and further comprises an isolation unit, wherein a through hole is arranged on the isolation unit; the isolation unit is sleeved on the strip body; the through hole and the strip body form a sliding-inserting state; and the aperture of the through hole forms a path at which the strip body penetrates up and down. Because the isolation unit limits the direction of the strip body and isolates the strip body and the installation hole on the vehicle fixing part, so that only friction between the soft strip body and the isolation unit appears when the wire bundle oscillates caused by factors such as vehicle bumping to enable the cable tie to oscillate; finally, the wearing fracture condition caused by friction between the traditional cable tie and the sharp edge of the vehicle body can be avoided effectively; and the tying reliability is high and the usage is convenient.
