In the both sides of connecting support seat, ball pivot set and positioning ball, gland is fixedly connected with connecting support seat, and axle is reserved between gland and ball pivot set
To gap, force-transmitting block one end and connecting support seat key connection, the other end is with positioning ball pin key connection.
Ball pivot set includes two hemisphere hinge sleeves, and two hemispheres hinge sleeve surrounds ball pivot set.
The structure snd size of two hemispheres hinge sleeve are identical.
Connecting support seat is monolithic construction.
Gland is monolithic construction.
One end of force-transmitting block and connecting support seat key connection is rectangle, and force-transmitting block and one end of positioning ball pin key connection are cylinder
Shape.
Shaft coupling also includes lubricating cup, and shaft coupling is extended in lubricating cup one end, and the other end is located at force-transmitting block position, and gland is with coupling
