When the limiting device 5 is used, when the tube rolls to the top of the operating table 1 close to the hydraulic device 3, the second spring 503 presses the arc plate 504 in the direction away from the L-shaped plate 501, so that the arc plate 504 is pressed on the surface of the tube, thereby well limiting the tube to the top of the operating table 1. A rubber plate 507 is fixedly connected to one side of the operating table 1, and one side of the rubber plate 507 is evenly A circular groove 508 is provided, and the tube embryo hits the rubber plate 507 fixed on one side of the operating table 1, thereby causing the rubber to be squeezed and deformed, which can play a certain buffering role, wherein the circular groove 508 can increase the deformation degree of the rubber plate 507, which can increase the buffering effect to a certain extent.
