Claims

[Scope of Claim for Utility Model Registration] 1. A bucket belt and a pair of left and right upper links whose upper end attachment parts are located outside the upper side plate of the bucket belt are rotated by a tip pin at the tip of an arm constituting a working machine. The lower part of the upper link has a connecting pin hole perpendicular to the pin hole of the tip pin, and the connecting pin hole has a connecting pin hole at the upper end. The upper ends of the links are connected by connecting pins, and the intermediate part of one lower link and the end of the other lower link are provided with link connecting pin holes for connecting the lower links,
A rod connecting pin hole is provided at the lower end of one of the lower links, and the lower links are connected to each other by a connecting pin inserted into the link connecting pin hole, and the upper end of the rod is inserted into the rod connecting pin hole. are connected by a connecting pin, and the lower part of the rod is provided with a box with a receiving part for the toe of the bucket and a hook supported by the box, and the lower link and upper link of one of the rods connected to each other are provided. A locking pin hole is provided in the vicinity of the connection with the left and right lower links, into which the locking pin is inserted when the lower links are disconnected from each other, and the metal fittings for fixing the box and hook in the storage position are attached to the arm. A hydraulic excavator crane device characterized by being installed on the side. 2. A locking pin that connects the lower end of the rod and the upper end of the box by a connecting pin inserted into a connecting pin hole provided in both, and inserts a locking pin into the other part of both. Claim 1 in which a hole is provided
