As the utility model discloses a further optimization scheme, load cabin loading load, when the hatch door was closed, steering wheel rocking arm, the perpendicular hatch door of vertical load axle upwards, the hatch door was transmitted to the vertical decurrent gravity of load this moment, by the hatch door open end is transmitted for acting as go-between, again by the acting as go-between transmits for vertical load axle, vertical load pole this moment only receives the effect of axial force, transmits the axial force as tangential force by the load axle at last for digital steering wheel, rudder frame, load cabin.
As a further optimization scheme of the utility model, the digital steering engine only bears the tangential force in the whole process, and does not bear the torque, and the mechanism forms a self-locking mechanism; when the digital steering engine transmits torque, the steering engine rocker arm and the longitudinal bearing shaft rotate by a certain angle, self-locking is released, the longitudinal bearing rod bears the torque and does not bear axial force, the stay wire is loose, and the cabin door is opened.
As a further optimization scheme of the utility model, the one end of vertical load pole is for connecting act as go-between, the other end is for connecting on the steering wheel rocking arm.
Compared with the prior art, the beneficial effects of the utility model are that: this novel can the less great load of steering wheel control of power used, the load gravity that will bear originally transmits whole fuselage frame, and the auto-lock structure transmits the axial force that the force bearing pole received for the steering wheel as tangential force, and the protection steering wheel does not appear smooth tooth phenomenon or gear fracture, increase of service life. The whole feeding mechanism saves cost and materials, can greatly save the space of the device and reduce the weight of the device.
