Magnetic rigid chain push-pull actuating mechanism

The utility model discloses a magnetic rigid chain push-pull executing mechanism which is composed of a driving chain wheel, a driven positioning chain wheel, a magnetic rigid chain, a driving motor,a fixed rack and a fixed rack packaging plate. The magnetic rigid chain is composed of a connecting pin, a plurality of common chain links, a connecting chain link and the like. The rigid chain with magnetism is limited by the driving chain wheel, the driven positioning chain wheel and the chain limiting groove to be flexible when located in the fixed rack, and the rigid chain with magnetism is rigid under the magnetic force between the chain links when located outside the fixed rack. According to the mechanism, the conversion between the flexibility and the rigidity of the magnetic rigid chain is realized through the driving of the driving chain wheel, so that the mechanism has a push-pull effect. 本实用新型公开了一种磁力刚性链条推拉执行机构，它由驱动链轮、从动定位链轮、具有磁性的刚性链条、驱动电机、固定机架和固定机架封装板构成。具有磁性的刚性链条由连接销、若干普通链节和一个连接链节等构成。具有磁性的刚性链条位于固定机架内部时受
