Links 2 and 3 are pivotally connected to the arm 1 connected to the hydraulic cylinder 4 via pins 7 and 8, and the back of the attachment is pivotally attached to the tip of the link via pins 5 and 6. In an earth-moving machine that constitutes an arm link mechanism, a hydraulic cylinder 9 that can extend and retract in opposite directions is mounted between the pins 5 and 6, and the pins 5 and 6 are mounted on the back of the attachment. An opening 11a into which the end of the pin 6 is inserted, and a fitting groove 1 behind the opening 11a that opposes and prevents the extension movement of the pin.
An attachment exchange device characterized in that a pair of left and right engaging parts 11 having opposing attachment parts 1b are arranged side by side. 2 Utility model registration claim 1 in which convex edges are formed at the ends of the pins 5 and 6, and grooves 11c are carved in the engaging portion 11 to fit with the convex edges 5a, 6a.
Attachment exchange device as described in section.
