Claims

[Scope of utility model registration request]

A steering handle 7 is equipped so as to be freely redirectable in the longitudinal direction of the aircraft, and on the side of the transmission case 3 there are both transmission shafts 12, 11 for high speed and low speed of the main transmission.
In a management machine configured by disposing and sub-shifting shaft 13, a frame 17 that can rotate around a horizontal shaft 9.
A change lever 8 is attached to the base side of the change lever 8 so as to be freely swingable in the front and back directions, and a spring 24 is attached to the base side of the change lever 8.
The restraint plate 8d, which is held in a fixed position by the brake plate 8d, is rotatably connected and disengaged from the change arm 18a, which can be selectively engaged with both the speed change shafts 12 and 11 when changing the change lever 8 in the front-back direction. A restraining rod 21 is fitted into the frame 17 so as to be biased upward and movable in the vertical direction.
is provided, and when the change lever 8 is moved forward, the check plate 8d also rotates at the same time and is positioned above the upper end 21a of the check rod 21, and the change lever 8 is moved downward and the check plate 8d is moved forward. When engaged with the arm 18a, with this movement, the check plate 8d comes into contact with the check rod 21 and pushes down the check rod 21, causing the lower end 21b of the check rod 21 to further protrude downward, and the change lever 8
When operating the change arm 18a to engage the high-speed transmission shaft 12, the protruding lower end 21b of the check rod 21 is positioned within the shift area for shifting the sub-transmission shaft 13 to the high-speed side. In addition to restraining high-speed backward movement, the restraint plate 8d is rotated under the tension of the spring 24 to release the restraint from the upper end 21a of the restraint rod 21, thereby releasing the restraint. A high-speed reverse check and release device for a control machine, characterized in that:
