Multi-connecting-rod pipeline pulley

The multi-connecting-rod pipeline pulley comprises a positioning bottom plate and a movable plate, bearing assemblies are fixed to the outer walls of the two sides of the positioning bottom plate at equal intervals, a fixed plate is fixed to one side of the upper surface of the positioning bottom plate, and the movable assemblies are arranged on the sides, away from the fixed plate, of the two sides of the upper surface of the positioning bottom plate. According to the multi-connecting-rod pipeline pulley disclosed by the utility model, the second rotating shaft can be mounted through the two connecting blocks, cables can be transported through the rotating rollers rotationally mounted outside the first rotating shaft and the second rotating shaft, and a user inserts the cables into the two rotating rollers; and then when the cable is pushed backwards, the conveying direction of the cable can be limited through the two rotatable rotating rollers, the situation that the cable is inconvenient to push due to lef
