Circuit harness binding device

The utility model discloses a circuit harness binding device which comprises an installation base, a fixed harness plate is fixedly connected to the top of the installation base, sliding grooves are formed in the two ends of the fixed harness plate, and movable harness plates are slidably connected to the inner walls of the sliding grooves. One end of the movable wire bunching plate is fixedly connected with one end of the fixed wire bunching plate through a fastening mechanism, a protection assembly is arranged on the inner surface side of the fixed wire bunching plate, and supporting assemblies are arranged on the two sides of the fixed wire bunching plate. According to the circuit harness binding device, through the arrangement of the fastening assembly, the periphery of the movable harness plate can be tightly attached to the inner wall of the sliding groove in the fixed harness plate, so that the circuit harness can be firmly fixed, and scattering of circuits is avoided; the pressurization air bag extrud
