Along with the tight inserted block 13 downstream in top, on the one hand, can effectively drive cable clamping wedge 12 further to press from both sides tight cable, on the other hand, can utilize the inclined plane of cable clamping wedge 12 rear surface and slot 17 rear surface, to a certain extent drive cable fixing device 7 forward motion for the upper portion mounting panel 5 of cable support, further realize the effect of flare-outing of cable. The cable fixing device 7 installed on the cable support 6 can utilize the cable clamping wedge 12 to realize automatic clamping by the action force of the gravity of the rear cable on the one hand, and can stably utilize the inclined plane to be inserted into the slot 17 of the cable support by the action of the gravity of the front and rear cables on the other hand, so that the cable fixing device 7 cannot fall off even if a gap exists between the front of the jacking insertion block 13 and the through slot of the jacking insertion block. Simultaneously, the cooperation of a plurality of inclined planes between the different parts is used, has played the effect that the inclined plane auto-lock was pushed up tightly with the drive, and the effectual fixed reliability of having guaranteed the cable prevents the phenomenon of droing that the cable causes because of fixed not tight, has also avoided the cable to cause because of fixed tension, contact surface undersize the damage phenomenon of the outer insulating layer of cable. In the invention, the cable fixing device 7 has the characteristic that the cable cannot return after being installed, so that the device can always keep the cable in a stretched state without using a large-scale cable traction device when the cable is laid, the cable can be fixed by using a sectional installation mode and a cable erection device which is small in size and convenient to move and is matched with a rubber hammer, and the labor intensity of cable laying is greatly reduced. The invention adopts a modularized form, can realize the quick laying of cables, is suitable for the laying of cables with different wire diameters, and has higher universality.
