In order to achieve the effect of locking the catch ring 4 to the joint housing 3, a locking device 43 is arranged in the inclined raceway 42. In this embodiment, the preferred component of the clamping device 43 is a spring. One end of the clamping device 43 is fixed at the closed end of the inclined raceway 42, the other end of the clamping device 43 is fixed with a sliding clamping jaw 44, and the sliding clamping jaw 44 is matched with the clamping steel ball 21. The sliding claw 44 is arranged in the inclined raceway 42, when the clamping steel ball 21 rolls along the inclined raceway 42, the sliding claw 44 can be pushed to slide towards the closed end of the inclined raceway 42, and the sliding claw 44 extrudes the clamping device 43. The side wall of the inclined rolling path 42 close to the tail end is provided with a sliding groove 45, a sliding block 46 is arranged in the sliding groove 45, one end of the sliding block 46 is inserted into the inclined rolling path 42, and the other end of the sliding block 46 is fixed with a tension spring 47. The side of the slider 46 facing the opening of the inclined raceway 42 is a circular arc surface. The sealing section of the inclined raceway 42 is provided with a notch adapted to receive the chucking steel ball 21, and a slider 46 is provided outside the notch. When the clamping steel ball 21 pushes the sliding jaw 44 to slide in the inclined raceway 42 until the sliding jaw 44 abuts against the sliding block 46, the sliding jaw 44 can push the sliding block 46 to retract into the sliding groove 45 through the arc surface, so that the tension spring 47 is compressed until the clamping steel ball 21 and the sliding jaw 44 both move to pass through the sliding groove 45 and enter the notch. The tension spring 47 pushes the slide block 46 to be inserted into the inclined raceway 42 again to seal the opening of the notch, so that the steel ball 21 is clamped. At this time, the locking balls 21 push the locking ring 4 to axially slide against the joint housing 3, thereby locking the locking ring 4 to the joint housing 3.

In order to facilitate the resetting of the clamping steel balls 21, one end of the tension spring 47, which is far away from the sliding block 46, is fixed on a resetting plate 48, and the resetting plate 48 is slidably arranged on the outer wall of the clamping ring 4. When the reset plate 48 circumferentially slides around the latching ring 4, the sidewall of the reset plate 48 pulls the tension spring 47 to slide outward, so that the tension spring 47 pulls the slide block 46 to retract into the slide groove 45, thereby releasing the latching steel balls 21, so that the latching device 43 pushes the sliding pawl 44, and the sliding pawl 44 pushes the latching steel balls 21 to reset.

In addition, two limit plates 49 are fixed on the outer wall of the latch ring 4, the limit plates 49 and the reset plates 48 are respectively disposed on two sides of one sliding slot 45, and when the reset plates 48 slide to abut against the limit plates 49, the clamping device 43 pushes the sliding block 46 to be inserted into the inclined raceway 42.
