摘要
A tail block assembly for a carpet stretching apparatus comprises a tail block mounting structure, a displacement device engaging structure and a multi-axis swivel joint. The multi-axis swivel joint includes a first yoke structure fixedly attached to the displacement device engaging structure, a second yoke structure fixedly attached to the tail block mounting structure and a linkage member pivotably connected between the first yoke structure and the second yoke structure. The first yoke structure pivots about a first pivot axis of the linkage member and the second yoke structure pivot about a second pivot axis of the linkage member. The first pivot axis extends approximately perpendicularly through the second pivot axis. The first pivot axis extends approximately perpendicular with respect to a longitudinal reference axis of the displacement device engaging structure and the second pivot axis extends approximately perpendicular with respect to a longitudinal reference axis of the tail block mounting structure.
