Connection device for guider in power turbine

The invention discloses a connection device for a guider in a power turbine. The connection device is used for connecting a drive independent gear ring of the guider in the power turbine with a driveshaft of an execution accessory, wherein a plurality of guide blades are uniformly distributed on the guider in a case of the power turbine along the axis of the power turbine; each guide blade is equipped with an independent gear ring forming engagement transmission with a synchronized-driving large tooth ring through a bevel gear pair; one independent gear ring is a drive independent gear ring,and comprises an in-line joint arranged on the drive shaft, and a rectangular lug arranged on the end surface of the drive independent gear ring; and the in-line joint and the rectangular lug are connected through a cross connection shaft. The connection device for the guider in the power turbine is simple in structure and low in manufacturing cost; and the deflection of the axis is allowed, so that installation for the ex
