The spherical joint is rotatably disposed in the containing recess, and the surface of the spherical joint has a plurality of positioning holes. The positioning pins are disposed at the bearing seat and capable of sliding toward or away from the spherical joint. The positioning pins correspond to parts of the positioning holes respectively when the spherical joint rotates to a specific position relative to the bearing seat. The retaining ring is disposed at an opening of the containing recess of the bearing seat and surrounds the positioning pins, the retaining ring is against the positioning pins to allow the positioning pins to be fastened in the corresponding positioning holes when the spherical joint rotates to the specific position relative to the bearing seat.
