Abstract
A quick coupler includes a male part externally provided with a radially protruded portion having a slanted pushing surface and a chamfered locating surface, and a female part provided with two circular rows of staggered first and second through holes for receiving first and second steel balls therein, respectively. The female part includes a front and a rear female case and an outer sliding sleeve slidably fitted on the front female case and a spring located outside the front female case. When connecting the male to the female part, the protruded portion sequentially pushes the staggered first and second steel balls, which in turn drive the outer sliding sleeve rearward to an unlocking position. When the first steel balls are moved to the locating surface, the outer sliding sleeve is pushed by the spring to press against the steel balls and firmly lock the female part to the male part.
