Abstract

PROBLEM TO BE SOLVED: To replace only an excavating plate when the excavating plate is worn by constituting a claw holder of the excavating plate, in which front and rear sections are formed in a tapered shape, and a claw inserter, to which a clamping-bolt inserting hole and a claw small inserting hole are formed. SOLUTION: A claw holder 1 is composed of an excavating plate 2 and a plurality of claw inserters 3, 4, 5. The claw inserters 3, 4, 5 are installed detachably to the excavating plate 2 by clamping bolts. Projecting sections are formed to the claw inserters 3, 4, 5. Clamping-bolt inserting holes are formed to the projecting sections, and the clamping bolts are inserted and the claw inserters are mounted on the excavating plate 2. When the excavating plate 2 for the claw holder 1 is worn by usage, only the excavating plate 2 is removed, and a new excavating plate 2 is clamped and fixed to each claw inserter 3, 4, 5 by the clamping bolts.
