(5) specific embodiment:
A kind of spherical hinge type joint electric locking device of the present invention sees also Fig. 1 to shown in Figure 5, and it comprises:
One ball rod 1, one end are spherical round end, and an end is a cylindrical bar;
One ball-joint seat 2 is the round-meshed cylinder in centre; The one end is the Internal Spherical Surface shape, cooperates with the spherical round end of ball rod; Its inwall upside has the half slot (not shown) of circumference uniform distribution;
One pushes ball watts 3 is the cylinder that an end digs the sphere of indent, and its outer rim has the half slot 31 of circumference uniform distribution, cooperates with the half slot of ball-joint seat inwall to form circular hole so that ball to be installed;
One thread spindle 4 is the protruding cylinder that an annulus 41 is arranged in a middle part; Its top is drilled with circular hole 42 and has keyway 43; The bottom is processed with the triangle external screw thread;
One ball support ring 5;
