This utility model discloses a netting lifting system, including a netting rack end face. Each of the four corners of the netting rack end face is equipped with a traction execution module. The inner side of each traction execution module is provided with a traction limiting guide rail, a transmission end connecting unit, and opposing limiting pillars. The traction limiting guide rail is used to slide and limit the vertical lifting of the traction execution module. The netting rack support module is connected to a breeding platform, and the transmission end connecting unit is connected to the platform's traction end, providing power transmission for the vertical lifting of the traction execution module. The symmetrical arrangement of the traction limiting guide rail and the opposing limiting pillars forms a rigid track, allowing the directional roller transmission component to have fitting guide cavities on both sides that strictly engage with the pillars, forcibly limiting its sliding only in the vertical direction. This greatly restricts the horizontal degree of freedom, ensuring that the lifting process strictly follows a vertical path, reducing swaying and deviation, and improving the overall stability after lifting and adjusting.
