Accordingly, the link member 452 can rotate together when the moving hook 130 rotates. Accordingly, the link member 452 may rotate to engage the locking hook 151 with the first coupling pin 21 when the moving hook 130 is rotated in the direction in which the moving hook 130 is engaged with the second coupling pin 22. . In addition, the link member 452 may rotate to release the locking hook 151 from the first coupling pin 21 when the moving hook 130 is rotated in the direction of release from the second coupling pin 22. .

- the linkage mechanism may include a rotating body 652.
- the rotating body 652 is included in the locking hook 151 to lock the moving hook 130 by pushing the rotating body 652 of the locking hook 151 directly when the moving hook 130 is rotated without using another interlocking mechanism.
- Hook 151 can be engaged and dismantled.
- the locking hook 151 may be formed to protrude from the coupler body 110 in a state of being coupled with the first coupling pin 21. Accordingly, the driver directly determines whether the first coupling pin 21 is fully engaged with the fixing hook 120 in the driver's seat, and the second coupling pin 22 is completely connected with the movable hook 130. You can indirectly determine whether it is in a coupled state. Therefore, it is possible to conveniently check whether the attachment 20 to the coupler 100 is fully mounted. In addition, due to the incomplete mounting of the attachment 20, it is possible to prevent the problem that the attachment 20 is separated from the coupler 100 in advance.
