スオーガ接続具。 The upper part of the digging tool 5 at the lower end becomes the cylindrical shaft 8,
The cylindrical shaft of the earth auger A, whose cylindrical shaft rotates and slides up and down in a bearing cylinder 10 of a steady rest device 9, etc., is fitted into the male and female holes 11 and 12 of the cylindrical shaft. A common pin 15 is driven into the pin hole 18 having a pin hole opening 18a on the side and the groove 14 on the side of the male shaft, and an outer peripheral groove 16 is inserted into the outer peripheral surface of the cylindrical shaft so as to pass through the pin opening 18a. An earth auger connector is provided in which a ring 17 is removably fitted into the outer circumferential groove 16 without protruding from the outer circumferential surface of the cylindrical shaft.
