Abstract (en)
The present invention relates to a quick coupler connection system for a construction machine in which the coupling position of an actuating rod and a connecting block is automatically adjusted so that a quick coupler main body and a heavy equipment attachment device are quickly and safely combined, in which the quick coupler main body and the attachment device can be more easily combined, a stronger connection force can be achieved, and operation noise can be reduced by combining the quick coupler main body and the attachment device in a 3-point supporting type and a pin-hook coupling type.
