Device for rapidly fastening communication cables

A device for rapidly fastening communication cables comprises a fastening body, wherein two port positions of an inner wall of the fastening body are respectively provided with gear teeth which are uniformly distributed in a circumferential manner; by using a center line of an end surface at one side of the fastening body as a notch, the fastening body is cut along the axis of the fastening body and is divided into two parts including a first fastener and a second fastener which are symmetrical with each other; each of the first fastener and the second fastener is provided with a hinged surface and a folding surface; the first fastener and the second fastener are mutually hinged at the hinged surfaces of each other, and a round tube shape is formed when the first fastener and the second fastener are closed; the outer side edge of the folding surface of the first fastener is provided with a plurality of clamping buckles or/and clamping rings; and the outer side edge of the folding surface of the second fastener is provided with a plurality of clamping rings or/and clamping buckles which are matched with the clamping buckles or/and clamping rings. According to the device for rapidly fastening communication cables, fastening motion is very convenient, occlusal force of the gear teeth on cable cover layers is relatively large due to fastening force generated after fastening is carried out, and two cables are not easy to break after being fixed.
