Claims

[Scope of utility model registration request]

At the center of the upper part of the downward arc-shaped Hitsuchi frame,
A top hook is fixedly installed to receive the connecting pin of the top mast of the work equipment, and a lower hook is provided on both sides of the lower part of the hitch frame with a socket for receiving the connecting pin of the lower bracket on both sides of the lower part of the work equipment, and a hook plate for opening and closing the socket. is fixedly installed, and the top hook and the lower foot on both sides of the lower part are respectively pivotally connected to the tips of the top link extending from the rear of the tractor and the lower links on both sides of the lower side. A coupling release lever is pivotally attached to the upper part of the plate, the central part stands upward in a wide downward U-shape, and the upper horizontal part is a grip part, and is movable along an L-shaped guide path. The movement of the release lever is linked to the opening/closing movement of the hook plate, and a return spring is attached to the release lever to urge the lever to the hook plate closed position at the hook end of the L-shaped guide path. Attached to the center line, the hook plate is equipped with a spring stopper that moves out and closes the hook plate when the work equipment is connected, and prevents the hook plate from closing when the hook plate is released from closing or when the work equipment is completely detached. A tractor hitch device that is characterized by:
