Claims

[Scope of utility model registration request]

In a free joint mechanism that holds a sphere rotatably or fixably and positions a support rod or the like provided on the sphere, there is a casing having a concave portion for storing the sphere, and a casing from the side of the casing for holding the sphere in the concave portion. a clamping seat having a spherical shell-shaped clamping surface that is movable into and out of the recess, and a receiving seat having a spherical shell-shaped clamping surface opposing the clamping seat;
It has an insertion port for introducing the sphere, which is provided through a side surface of the casing that is different from the clamping direction, so as to increase the degree of freedom in positioning the support rod, etc. that extends through the opening of the recess in the direction of introducing the sphere. free joint mechanism.
