A connecting device of a soil removing member for an excavator is used for connecting two soil removing members, wherein a helical ejecting blade is attached on an outer periphery of a rotational shaft. The rotational shaft in one soil removing member is connected to another rotational shaft of another soil removing member in accordance with excavation. The connecting member is basically formed of an inserting member disposed at one end of the rotational shaft, and a receiving member provided at the other end of the rotational shaft.

A hammer device is coupled to an outer portion of a handle, an operating portion is attached to the other portion of the handle, a holding section is attached to one side of the operating portion, and at the same time, a pair of excavators is rotatably attached to an outer portion of the holding section to conduct a bumping operation and opening and closing operations upon transmission from the operating portion. By this, burdens imposed on workers are reduced, at the same time, security of work is assured and time required for completion of works can be greatly shortened and reduced.

A rotary gad for a ground drill includes an elongated front body having a front end and a rear end with front spiral blades being disposed on the outside of the front body. The front body has an elongated front axial passage, and a front core rod is disposed in the front axial passage. The front body is rotatable about the front core rod. The front core rod has a front end and a rear end. An elongated rear body has a similar construction and a pushing section is provided on a rear axial passage in the rear body. The pushing section has a front side and a rear side. A rear ball element is disposed between the rear side of the pushing section and the front end of a rear core rod, and a front ball element is disposed between the front side of the pushing section and the rear end of the front core rod. Coupling means couple the front and rear bodies to provide for rotation of the front and rear bodies in opposite directions about the front and rear core rods.
