Positioning lock seats are provided on all four sides of the fixed bottom plate to fix the push rod in different directions. When the swivel seat rotates, the upper ball and the lower ball slide synchronously in the upper slide groove and the lower slide groove respectively, so as to reduce the friction resistance generated between the contact surface of the swivel seat and the supporting flat plate and the fixed bottom plate when the swivel seat rotates, thereby improving the smoothness of the swivel seat rotation and avoiding jamming.

[0010] The fastening buckles on both sides of the utility model are oppositely buckled and fixed on the outside of the fastening support sleeve. The fastening clamping plate on the inner side increases the connection fulcrum between the fastening buckle and the fastening support rod, and limits the position of the threaded support rod so that the longitudinal height is kept unchanged and the axial rotation is adjusted to avoid the rod from deviating and falling, which would affect the linkage effect between the components and improve the structural stability.
