Claims

[Scope of Claim for Utility Model Registration] (1) A fixed base member supported by a main body arm of an earthmoving machine, etc., and a fixed base member provided so as to be movable back and forth along the longitudinal direction, so that sheet piles can pass in the direction of movement. A movable base member having a possible through opening, and fixed teeth and a rotating chuck member are installed facing each other on the movable base member, and the chuck member is rotated by rotating the rotating base end of the chuck member toward the pile pulling side. a clamping device whose movable tip is pressed between fixed teeth; and a clamping device which is engaged with the fixed base member and the proximal end of a rotating chuck member of the clamping device, so that the rotating operation of the chuck member and the reciprocation of the movable base member are performed. A drawing device characterized by comprising a drawing drive means that moves in conjunction with the drawing device. (2) The extracting device according to claim (1), wherein the extracting drive means is a hydraulic cylinder.
