2Length L greater than the screw rod of the other end
1, two drilling rods are by the screw rod docking of different length, the joint cap nut, and nut is located by locator card.
Honeycombed drilling rod in the utility model comprises at least two endoporus, establishes alignment pin between the endoporus of two drilling rods, and described alignment pin is tubulose.The width L of locator card
4Width L with nut
3Sum is less than or equal to two spiro rod length L
2With L
1Sum.Locator card is jump ring, is installed in the draw-in groove that arranges on the screw rod.Perhaps locator card is pipe collar.Wherein, two semicircular ring of pipe collar for linking together by the hinged connection of an end, semicircular ring is fixed on the screw rod by screw.Perhaps, two semicircular ring of pipe collar for linking together by the hinged connection of an end, the other end of semicircular ring is bolted.Perhaps pipe collar is for being fixed on the elastic circular ring on the screw rod by screw (10), and elastic circular ring inner surface circumference is greater than nut external surface circumference.Perhaps pipe collar is two semicircular ring that an end links together by hinged connection, and the other end of two semicircular ring is the profile of tooth that shape matches, and profile of tooth is provided with collision bead.
The utility model has the advantage of: because locator card is spacing fixing to nut, can make the drilling rod after the connection can bidirectional rotary then do not come off.
