摘要： A quick disconnect coupling for releasably connecting a lift truck attachment to a lift truck carriage including a body adapted to be connected to the attachment. The body includes a vertically extending opening and includes a horizontal opening. A locking slide is vertically movable in the vertical opening for extending upwardly for attachment to and movable downwardly for disconnection from a lift truck carriage. A release and locking button is horizontally movable in the horizontally extending opening and extends through a bore in the locking slide. Coacting shoulders on the slide and on the button hold the slide in an extended and locked position when engaged and allow the slide to retract when disengaged. Spring means urge the button in a direction to engage the coacting shoulders. Releasing means on the button are provided for moving the button to a disengaging position. The body may include fastener openings on which includes a hexagonal recess for receiving a hexagonal nut or a circularly headed bolt whereby the body can be secured to the attachment by various types of fasteners.
