In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a rotatory nipple joint of oil pipe drilling rod, includes top connection, check fender nut and lower clutch, the top connection is hollow structure, the one end of lower clutch is passed the top connection and is connected with the one end block of top connection, check fender nut threaded connection is in the top connection, the one end both sides that the lower clutch is close to check fender nut are provided with two sets of steel ball grooves respectively, and are two sets of the steel ball inslot corresponds respectively and is provided with two sets of rotatory steel balls.

Further, the surface of the rotating steel ball is higher than the plane of the steel ball groove.

Furthermore, a spacing bulge is arranged between the two groups of steel ball grooves.

Further, the number of the rotating steel balls is 4.

Furthermore, one end of the upper joint is connected with an oil pipe drill rod.

Furthermore, one end of the lower joint is connected with the battery barrel.

Compared with the prior art, the utility model has the beneficial effects that: the rotary torque releasing device realizes the rotary function between the oil pipe drill rod and the battery barrel through the two groups of rotary steel balls arranged between the upper joint and the lower joint, thereby releasing the rotary torque between the oil pipe drill rod and the battery barrel, and has the advantages of simple structure, low price, easy processing and convenient installation.
