1. A latch assembly, comprising:
a cylindrical main body having a main body interior, an outer wall, a main body end and a latch end; a ball hole defined through said main body; an inner shaft ball lock contained within said main body underlying said ball hole; a roll pin secured to said main body and within said main body interior positioned transaxially and bisecting said main body, said roll pin positioned downstream of said inner shaft ball lock and abutted by an outer end of said inner shaft ball lock to limit axial movement of said inner shaft ball lock; a spring having a first end and a second end, said spring disposed on a medial portion of said inner shaft ball lock; a main body top attached to said main body end having a circular outer portion and a threaded inward portion axially aligned therewith configured to be connected within said main body near said main body end to contain said inner shaft ball lock within said main body and limit upstream movement of said inner shaft ball lock; a ball captured between said inner shaft ball lock and said outer wall of said main body such that upon axial movement of said inner shaft ball lock said ball penetrates up through said outer wall to extend past said main body to thereby latch onto an outer tube assembly; and, a ring-shaped ball flange, said ball flange encircling said inner shaft ball lock and defined towards a proximal end of said inner shaft ball lock and integral thereto, said ball flange having a flange diameter greater than both said proximal end and said medial portion of said inner shaft ball lock, wherein axial movement of said ball is limited by one side of said ball flange and axial translation of said spring is limited by an opposing side of said ball flange. |
