Abstract

PURPOSE: To remarkably simplify the structure of a quick coupler and the connecting and disconnecting operations thereof by providing a hook having a hitch including an intermediate connector and an intermediate portion made of key type member.
CONSTITUTION: When a pair of upper connectors 18a, 18b of a hitch 6 are connected to a pair of upper retainers 50a, 50b of a hook 10 and a pair of lower connectors 20a, 20b of the hitch 6 are connected to a pair of lower retainers 52a, 52b of the hook 10, a pair of connecting pins 34a, 34b of the hitch 6 are automatically inserted into a pair of pin retaining holes 54a, 54b of the hook 10 to thereby readily and exactly connect the hitch 6 to the hook 10. Thus, a working instrument 8 is readily and exactly connected to a civil engineering vehicle.
