Abstract: A connecting mechanism includes a first section and a second section engageable with the first section. The second section includes a locking assembly configured to engage a stud with a roller bearing in the first section. That is, the locking assembly is actuatable between a locked state configured to lock the first section to the second section when the first and second sections are engaged and an unlocked state configured to allow the second section to engage with or disengage from the first section. The locking assembly includes a linkage arm engaging a handle and a wedge having a tapered section. The handle is actuatable between a locked position configured to place the locking assembly in the locked state by advancing the tapered section of the wedge and an unlocked position configured to place the locking assembly in the unlocked state by retracting the tapered section of the wedge.
