<p>A coupling device (5a,5b,6...) for automatically coupling an excavating device (4) or a hammer device to an excavator includes an arm coupler (5a) fixed to one end of an arm (1) of the excavator and a link coupler (5b) fixed to an operation link (2) of the arm (1) of the excavator. The excavating device includes a pair of brackets (41a,41b) having a pair of the assembling holes (42a,42b,43a,43b). Piston rods (62a,62b,52a,52b), contained in the arm coupler (5a) and the link coupler (5b) and inserted into the assembling holes, connect the brackets (41a,41b) of the excavating device to the excavator. <IMAGE></p> |
