Abstract: A wire-shaped body winding mechanism provided by the present invention includes multiple rotary shafts for winding a wire-shaped body, where a main shaft member serves as a revolution central shaft and two split shaft members serve as rotation central shafts. The wire-shaped body is wound on the split shaft members and thus can be coiled or released with rotation of the main shaft member. Relative movement between the split shaft members and the wire-shaped body is realized through rotation of the split shaft members, and thus the wire-shaped body can move smoothly.

Abstract: The present invention provides a motion platform having a wire-shaped body winding mechanism, where the wire-shaped body winding mechanism is combined on one side of the motion platform to wind related pipelines, which prevents problems in operating security caused by dropping of overlong pipelines, makes the peripheral environment of the motion platform neat, and causes no vibration or noise pollution.

Abstract: A lifting mechanism with self-locking function, including an ascending/descending seat, a rocking member pivotally connected with the ascending/descending seat, a guide section and a prestressing section. The rocking member serves to convert a horizontal force provided by a power source into a vertical force to up and down reciprocally move the ascending/descending seat in the direction of Z-axis. The guide section includes guide members, which can be cross roller ways for guiding the ascending/descending seat to ascend/descend. The prestressing section can be adjusted to change the gaps between fixed guide rails and movable guide rails of the cross roller ways. Accordingly, the sliding friction between the fixed guide rails and the movable guide rails can be adjusted to provide auxiliary locking force for locating the ascending/descending seat.
