The invention relates to a simple movement mechanism with the movement direction capable of changing and a working method of the simple movement mechanism. The simple movement mechanism comprises a base, two sliding blocks driven by a linear driving mechanism to reciprocate towards each other in the opposite directions in the transverse direction are arranged at the lower end of the base, slidingrods are fixedly connected to the left and right ends of the lower surfaces of the sliding blocks correspondingly, swinging arms are symmetrically arranged on the left and right sides of the sliding blocks, and hinged to the base, and sliding grooves which are used for accommodating the sliding rods and forming sliding pairs with the slide rods are formed in the ends, close to the sliding blocks,on the swinging arms. According to the simple movement mechanism with the movement direction capable of changing, the structure is simple and reasonable, the movement direction of the swinging arms being connected with a clamp holder is changed conveniently, the swinging arms are detachable, assembled with different bases conveniently, and can further be assembled with different clamp holders according to the needs, and multifunctional use is achieved.

The invention discloses a tiltrotor unmanned aerial vehicle structure and its working method. By setting the duct roller on the outer ring of the turbine cover and being able to rotate relative to the turbine cover, the axis of the duct roller and the axis of the transmission shaft of the tilting mechanism Parallel; directly connected to the turbine cover through the transmission shaft of the tilting mechanism, and a fan blade power mechanism for providing power is provided in the turbine cover. At the same time, the ducted rollers are set on the outer ring of the turbine cover, and the turbine cover and the ducted rollers form a circular protection for the fan blade power mechanism at the same time. The shaft rotates to adjust the direction of the turbine cover, thereby adjusting the overall power output direction of the smart drone. The flight of this model realizes multifunctional use.
