Abstract: A flying wing-shaped saddle comprises a saddle integrally formed by a plate body with a U-shaped trough for guiding airflow, a butterfly wings symmetrically extended from the left and right end of said trough respectively, which is used for sitting thereon, and a bow formed by a bent rod which comprises a fixing part, a buffering part and a support part, said fixing part formed by two rods disposed in parallel and fixed on the seat post of the bicycle, said buffering part formed by two rods extending from two front ends of said fixing part, said supporting part formed by two rods which are extended outwardly, diagonally and symmetrically from the two back ends of said fixing part.

Abstract: The Structure of a Flying Wing-shaped Seat, which comprises of a Seat, is integrally formed by a plate body with a U-shaped Cross-section, said U-shaped Cross-sectional part is Diversion Trough with diversion ability, along with Butterfly Wings are symmetrically extended from the left and right end of said Diversion Trough respectively, which formed a seating position for the rider's buttocks to sit on; and a Bow, which is formed by a bent rod, comprises of a Fixing Part, a Buffering Part and a Supporting Part, said Fixing Part is formed by 2 rods disposed respectively on parallel, and fixed on the seat pillar post of the bicycle, said Buffering Part is formed by 2 rods extending parallel from the 2 front ends of said Fixing Part, said Supporting Part is formed by 2 rods which are extended outwardly, diagonally and symmetrically from the 2 back ends of said Fixing Part.

Abstract: An assembling mechanism of a self-locking linear actuator includes a gearbox, a one-piece rear retainer seat and a casing. The gearbox is composed of two half pieces, which are mated with each other for accommodating and locating a transmission mechanism of the actuator. The rear retainer seat is fixedly held in the gearbox for supporting a bearing of a threaded rod of the transmission mechanism and bearing the stress from the threaded rod. The contact faces of the rear retainer seat and the gearbox are regular polygonal to facilitate adjustment of fixing angle of the rear retainer seat. The casing is composed of two half casings, which are mated with each other to accommodate the transmission mechanism, the gearbox and the rear retainer seat. The mating faces of the half casings are parallel to the axis of the output shaft of a motor to facilitate connection operation of the casing.
