Claims

[Scope of utility model registration request]

One end of the suspension iron is connected to the tip of the boom, and the other end is connected to an expansion joint consisting of a sheath member made of a pair of parallel strips, and a link inserted into the sheath member so as to be slidable in the longitudinal direction. The sheath member is connected to the jib via a long hole along the length direction, the link is provided with several pin holes that can face the long hole, and one of the pin holes and the long hole are connected to the long hole. The jib is configured to be able to be supported in a number of large and small inclined positions by inserting a pin across the jib, and
A lock pin hole is provided in the sheath member and the link for fixing the two with a pin at the jib minimum inclination position to prevent the jib from stirring;
A jib inclination adjustment device characterized by being provided with a stopper for preventing separation of the two.
