Specific embodiment
As shown in Figs. 1-5, a kind of building blocks of movable connection of the utility model, including pedestal 1, the first rotating member 2 and
Two rotating members 3.A cavity is equipped in the pedestal 1.It is equipped in the two opposite side surfaces of the pedestal 1 and is connected to the of cavity
One through hole 102 and the second through hole 103.First rotating member 2 includes first body of rod 21 and is arranged in cavity and can rotate
Enclosed globe shade 22, described first body of rod, 21 one end are connected with enclosed globe shade 22, first body of rod, 21 other end through first through hole 102 and
It can be swung in first through hole.Second rotating member 3 includes second body of rod 31 and is arranged in 22 inner cavity of enclosed globe shade and can turn
Dynamic spherical portion 32, described second body of rod, 31 one end are connected with spherical portion 32, and second body of rod, 31 other end passes through described second
It through hole 103 and can be swung in the second through hole.When stirring second body of rod 31, spherical portion 32 can rotate in enclosed globe shade inner cavity.
