Computer network branching device

The invention discloses a computer network branching device, which relates to the technical field of computer equipment and comprises a branching shell, and the left and right side surfaces in the branching shell are fixedly connected with the left and right ends of a partition plate respectively. Through mutual cooperation of the square frame, the second pull rod, the clamping plate, the arc-shaped clamping block, a rope, a pulley, a second fixing rod, a fourth spring, a second square groove and a fixing shaft, a network cable can be clamped and fixed in the using process of the device, and the network cable is prevented from loosening and falling off when being pulled by external force; through mutual cooperation of the sealing box cover, the limiting net plate and the partition plate, the demultiplexer can be conveniently placed in the branching shell, so that the demultiplexer can be taken out and placed more conveniently, and meanwhile, the placement position of the demultiplexer can be limited; and thro
