therefore, the electromagnet 8 is clamped between the pull rod 3 and the limiting plate 9, and the electromagnet 8 can be prevented from sliding axially along the driving shaft 15 due to tension wires or pulling rod force under the blocking action of the limiting plate 9, so that the magnetic force generated after the electromagnet 8 is electrified acts on the adsorption pull rod 3 more, and the electromagnet 8 is prevented from moving relative to the pull rod 3 when the electromagnet 8 is electrified.
