Disclosed is portable and integrated synchronous connecting equipment for computer complex circuits. The portable and integrated synchronous connecting equipment comprises a junction box and a line concentration board, wherein threaded rods are fixedly mounted at the two ends of the junction box; fixed ears with holes are mounted at the two ends of the line concentration board; the threaded rod pass through the corresponding holes of the fixed ears; nuts are mounted on the end parts of the threaded rods; the properties of the threaded rods are sleeved with first springs; the first springs are positioned between the corresponding fixed ears and the junction box; a plurality of connecting lines are arranged in the junction box; the two ports of each connecting line are formed in one side towards the line concentration board, and are formed in sequence vertically; a plurality of sliding grooves are formed in the two sides and the top of the junction box; the number of the sliding grooves in the two sides of the junction box is corresponding to that of the ports of the connecting lines of the junction box; sliding blocks, which can horizontally slide along the sliding grooves, are mounted on the sliding grooves in the two sides of the junction box in a matching manner; and the sliding blocks on the same side pass through the same first rotary shaft to be connected through bearings. By adoption of the portable and integrated synchronous connecting equipment, all equipment lines can be synchronously pulled out in a maintenance process of large-scale equipment, so that disconnection of all equipment can be completed in one time; and meanwhile, the portable and integrated synchronous connecting equipment is convenient and rapid to operate.
