Claims

[Scope of utility model registration request]

The handle of the swing stopper shaft for connecting the upper and lower bodies of construction machinery can be switched and locked along the guide groove of the positioning plate between the connected position and the open position to prevent the upper body from turning and to allow the upper car body to rotate freely. In the swing stopper mechanism for construction machinery, a spring for pressing the handle of the swing stopper shaft in the connected position and the open position is engaged between the handle of the swing stopper shaft and the vehicle body side. Stopper mechanism.
