Fixed, the other end withstands the end face of the larger one end of the pyramidal structure.
Preferably, two jointings are coaxially disposed and the corresponding first shell end connects formation one in opposite directions
The ready-packaged joint of coaxially connected two spirals.
It is furthermore preferred that two jointing nationalitys are tight by sliding slot sleeve and the bolt being set in the sliding slot sleeve
Firmware connection.
Preferably, the screw thread intermediate plate is three pieces total, and the outer sliding surface of each screw thread intermediate plate is one corresponding
The circular conical surface of 120 degree of central angles, the partial internal thread face of each screw thread intermediate plate are the interior spiral shells of corresponding 120 degree of central angles
Line face.
It is furthermore preferred that be equipped between the second shell intracavity sidewall and each screw thread intermediate plate matching guide groove and
Guide rail is slided for constraining each screw thread intermediate plate along the generatrix direction of the cone.
Preferably, the elastomer is spring.
Beneficial effects of the present invention:
The present invention realizes the quick connection of reinforcing bar, more convenient to use；Compared with traditional straight thread connector, rotation is eliminated
The operation of adapter can manually realize the connection of reinforcing bar, accelerate construction speed, at the same also be more convenient realize mechanization, from
Dynamicization, it is consistent with the trend of futurity industry development.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
