Under the locking state, the locking pin 33 is arranged in the pit 9, the rotary locking mechanism 3 further comprises a first spring 31 and a handle 32, the lower end surface of the fixing ring 1 is provided with a blind hole extending upwards along the axial direction, the outer wall surface of the fixing ring 1 is provided with a handle mounting hole, the blind hole is communicated with the handle mounting hole, the locking pin 33 is arranged in the blind hole, the handle 32 is fixedly connected with the middle part of the locking pin 33 and extends out of the handle mounting hole, the first spring 31 is sleeved on the upper part of the locking pin 33,

in one embodiment, the handle mounting hole is in the shape of a vertical key groove, and a notch is formed in the side edge of the upper end of the key groove in a material cutting mode to form an inverted L-shaped structure. The notch can position the handle 32 so that the handle 32 can be held in an unlocked position, and when the handle 32 is positioned at the lowermost end of the handle mounting hole, the stationary ring 1 is locked with the rotating ring 2.
