Spherical universal telescopic device

The invention discloses a spherical universal telescopic device. The spherical universal telescopic device comprises a first spherical base, a second spherical base, a short pipe ball and a long pipe ball, wherein the first spherical base and the second spherical base are symmetric; a first ball body is arranged at one end of the short pipe ball and fixed to the interior of the first spherical base through a pressing plate assembly; the ball center of the first ball body can be adjusted in the first spherical base; the short pipe ball can swing around the ball center; an inner movable pipe sleeve is arranged at the other end of the short pipe ball; a second ball body is arranged at one end of the long pipe ball and fixed to the interior of the second spherical base through a pressing plate assembly; the ball center of the second ball body can be adjusted in the second spherical base; the long pipe ball can swing around the ball center; an outer fixed pipe sleeve is arranged at the other end of the long pipe ball; the outer fixed pipe sleeve is matched and connected with the inner movable pipe sleeve. The spherical universal telescopic device is simple in structure, high in leakproofness and capable of meeting the requirements for absorbing the phenomena such as large deformation, displacement, deflection and stress concentration.
