Summary:PURPOSE:To promote the replacement work by disengageably locking a pair of pins provided on a working attachment, to a stationary hook and a movable hook which are provided in a working front part. CONSTITUTION:A pin 7' on a working attachment such as a bucket, is inserted into a hook part of a stationary hook 10. Then, a cylinder 12 is retracted so as to rotate a cam 11 in the direction of the arrow H in order to retain the coupling part between links 14, 15 in the direction of the arrow I. At this time, a movable hook 11 is rotated in the direction of the arrow J by means of the link 15 since the hook 10 side of the link 14 is supported by the pin 7'. After a pin 8' on the working attachment enters a hook part of the hook 11, the hook 11 is pressed in the direction of the arrow J by means of a toggle mechanism for the links 14, 15 so that the pin 8' is surely held. Further, in the case of the removal, the cylinder 12 is extended, the pin 8' is released from the hook 11 under the action of a return spring 17. With this arrangement, the replacement can be surely and rapidly made by only one operator.
