Abstract
A joint with a protrusion rod has a male buckle and a female buckle engaged with each other. The male buckled has a hollow insertion stub with multiple expansion slots and has a receiving hole to movably receive a protrusion rod. A distal end of the protrusion rod is movably engaged with the insertion stub. The protrusion rod has a locking plate and multiple fins correspondingly engaged with the expansion slots when the protrusion rod is wedged into the insertion stub. By having the above structure, difficulty of disengagement of the protrusion rod from the insertion stub is significantly increased to prevent the disengagement of the male buckle and the female buckle. Thus, the joint has increased combination strength and is excellent in utility.
