ーの接続構造。 A plurality of unit-shaped auger members each having a predetermined short size and having an insertion tube at one end and an insertion shaft at the other end are connected to each other through the connection between the insertion tube and the insertion shaft. In the replenishment type earth auger, in which a long auger is formed by adding the auger, the insertion cylinder and the insertion shaft of each auger member are connected in a direction perpendicular to the axial direction in which they communicate with each other. The holes are connected to each other through lock pins inserted into these connecting holes, and the lock pins have a length such that both ends protrude outward from the outer peripheral surface of the insertion tube, and grooves are formed at both ends. One end of a curved spring member having a length such that it is fitted over a half circumference of the outer circumferential surface of the insertion tube is rotatably attached to one of the split grooves via a pin, and the spring The other end of the material is provided with a locking piece with a hook that is bent inward in an inverted L shape, and the locking piece is attached to a lock pin that protrudes from the front connecting hole to the outside of the insertion tube. A connection structure for a supplementary earth auger, characterized in that the hook is engaged with the inner lower surface of the split groove while the other end is inserted into the split groove.
