This allows workers to place cables between the movable and fixed clamping plates. Place the cables one by one on the cable tray base plate between the fixed and movable clamping plates. Then, tighten the locking device on the connecting threaded rod to release the connection between the fastening thread end and the fastening thread post. Pull the connecting threaded rod to drive the drive rod, causing multiple movable clamping plates to move towards the fixed clamping plate. Under the action of the compression spring, the movable clamping plates move until they are in close contact with the outer wall of the cable, thus clamping the cable located between the movable and fixed clamping plates. Finally, tighten the locking device to screw the fastening thread end with the fastening thread post, thereby limiting and fixing the displacement of the movable clamping plates and ensuring the stability of the movable clamping plates in clamping and fixing the cables. This invention enables the separate placement of cables within cable trays, achieving categorized cable placement and preventing cables from becoming tangled. This facilitates subsequent cable maintenance by staff and is applicable to nuclear power plants and electronics factories. Attached Figure Description
