the fixed block is provided with a thread groove matched with the screw rod, the thread groove corresponds to the limiting groove, the fixed block is in a ring shape, the number of the limiting blocks is twelve, and the limiting blocks are cylindrical.

Preferably, the fixed block is provided with a groove corresponding to the screw.

Preferably, a clamping shaft is arranged at one end of the first shaft rod, and a clamping groove matched with the clamping shaft is fixed at one end of the second shaft rod.

Preferably, a retaining ring is fixed on the stabilizing block.

Preferably, a snap ring is fixed on the fixing block, and a fixing groove matched with the baffle ring is formed in the snap ring.

Preferably, a threaded hole matched with the screw rod is fixed on the limiting block.

Advantageous effects

The utility model provides a high moment of torsion transmission shaft. The method has the following beneficial effects:

this high moment of torsion transmission shaft, it is fixed with the spacing groove joint on the fixed block through the stopper on the steady piece, it is fixed with the stopper through the bolt, realize the quick dismantlement of first axostylus axostyle and second axostylus axostyle, solved traditional transmission shaft connected mode unstable to the problem of the difficult change of wearing and tearing and maintenance's problem appears easily, has improved life greatly, has reduced the maintenance cost.
