A construction machine having a mobile chassis (101), a bom (103) mounted on the mobile chassis (101) and capable of swinging vertically, and an arm (105) pivotally connected to the bom (103). An accessory detachable mechanism connects to a tip end of the arm (105). An accessory (114) is releasably held by the detachable mechanism. The mechanism includes a pivotal four-bar linkage (109) defined in part by the arm (105). First and second attaching arrangements (112, 113) are associated with the mechanism and releasably engage respective first and second attachment parts (116,117) provided on the accessory. The first attachment arrangement includes hooks (112,113) which engage the first attaching part as defined by a connecting pin (116, 117) on the accessory. A pressure cylinder (111) is associated with the mechanism to effect relative engaging or releasing motion between the first (112) and second (113) attaching arrangements. <IMAGE> |
