PURPOSE: An exchange device for an attachment is provided to reduce time required for exchanging an attachment by connecting or disconnecting the attachment using hydraulic pressure. CONSTITUTION: An exchange device for an attachment comprises a first coupling member(210), a first safety member(215), a second coupling member(260), a second safety member(265), and a hydraulic cylinder(240). The first coupling member is formed on one surface of a second coupling device(200) and has a dock in which a first circular bar(205) is inserted. The first safety member is coupled to the bottom end of the first coupling member and couples the first circular bar to the first coupling member. The second coupling member is formed on one surface of the second coupling device and has a dock in which a second circular bar(255) is inserted. The second safety member is coupled to the top end of the second coupling member and couples the second circular bar to the second coupling member. One side of the hydraulic cylinder is coupled to the first safety member, and the other side is coupled to the second safety member. |
