The invention relates to a grabbing branch chain of a grab bucket special for ball-like objects. The grabbing branch chain of the grab bucket comprises a bucket body. A fixed board is welded to the center of the inner wall of the bucket body. Eight sliding grooves are symmetrically formed in the left side wall and the right side wall of the bucket body. Two mounting boards are symmetrically welded to the left side wall and the right side wall of the bucket body. Two height adjusting branch chains are symmetrically installed on the upper side and the lower side of each mounting board and comprise two hydraulic cylinders installed on the two mounting boards respectively, wherein piston rods of every two hydraulic cylinders are installed on two pushing boards respectively; four connecting columns are symmetrically welded to the inner walls of every two pushing boards and penetrate through the corresponding four sliding grooves and a movable board welded into the bucket body. Two limiting springs are symmetrically connected to the two sides of each mounting board, and the top ends of every two limiting springs are connected to the corresponding pushing board. The grabbing branch chain can achieve the function of rapidly carrying the ball-like objects and has the advantages of being easy and convenient to operate, high in work efficiency, wide in application range and the like.
