Abstract:
1. A sliding mechanism, comprising: a first plate comprising a main body and two opposite guide rails, the two guide rails extending along the main body; a second plate comprising two guide grooves and longitudinally slidably connected to the first plate by a slidable engagement of the guide rails in the guide grooves; a linkage module being positioned between the first plate and the second plate and connecting the first plate and the second plate, the linkage module including an elastic unit and a linking unit, the elastic unit comprising a plurality of parallel coil springs, each coil spring having two ends, each end secured to an opposite portion of the linking unit, the linking unit defining a closed hexagon enclosing the plurality of coil springs and collapsible with the sliding of the first plate relative to the second plate, simultaneously driving the coil springs and the elastic unit to longitudinally extend or retract, the refraction beginning after maximum extension achieved, driving the linkage module and enabling the second plate to automatically slide along the first plate after the second plate moves a predetermined range of length relative to the first plate.
