The invention relates to the field of toy model airplanes and needs to solve the technical problems that a highly-simulated model airplane of a V-22 osprey is designed, can have the flight characteristics of the V-22 osprey and can be reduced to the specification size of a toy. A model airplane with vertical takeoff and landing, which is designed by the invention, comprises a fuselage, fixed wings and an empennage, wherein the fixed wings extend from both sides of the fuselage to the outside, the empennage is arranged at the tail part of the fuselage, the ends of the two wings are respectively provided with an airscrew engine, the rotation directions of the rotors of the two airscrew engines are opposite, the rotors of the two airscrew engines are connected into a whole by a rotating shaft mechanism distributed along the wings, the inside of the fuselage is provided with a rotating shaft driving mechanism, and the rotating shaft driving mechanism drives the rotating shaft mechanism to rotate so as to drive the airscrew engines at both ends of the rotating shaft mechanism to rotate synchronously between a vertical direction and a horizontal direction.

A dual-shaft hinge module including a first shaft, a first driving gear disposed on the first shaft, a second shaft, a second driving gear disposed on the second shaft, a pair of driven gears coupled between the first driving gear and the second driving gear, and multiple links is provided. The links are respectively pivoted to any two engaged gears to keep a center distance of the engaged gears fixed. A relative distance of the first shaft and the second shaft is changed along with different engagement positions of the driven gears relative to the first driving gear and the second driving gear. A portable electronic device is also provided.

The invention relates to the field of conveying and transporting equipment, and discloses an automatic material distributing and transporting mechanism. The automatic material distributing and transporting mechanism comprises a falling platform, wherein at least two falling grooves penetrating through the axial direction of the falling platform are formed in the upper end surface of the falling platform at intervals in the transverse direction of the falling platform in a sunken mode, and conveying belts for conveying in the axial direction of the falling platform are arranged in the falling grooves; empty installation cavities extending in the axial direction of the falling platform are formed in the two sides of the falling platform and between the adjacent falling grooves, and pushing locating mechanisms are arranged between the empty installation cavities and the falling grooves; and each pushing locating mechanism comprises a rotating shaft which extends in the axial direction ofthe corresponding empty installation cavity and then is rotationally connected with the two ends of the corresponding empty installation cavity, pushing parts which are arranged at the two sides of the corresponding empty installation cavity at intervals in the axial direction of the corresponding empty installation cavity and penetrate out of the corresponding empty installation cavity into the corresponding falling groove, and eccentric jacking mechanisms which are fixedly arranged on the rotating shaft and matched with the pushing parts in a guiding linkage mode. The automatic material distributing and transporting mechanism can automatically sort and convey products one by one in a straight line, so that high-efficiency transporting efficiency is maintained while the labor intensity isreduced.
