Referring to fig. 2, the outer wall of the joint body 1 is provided with two sliding holes 11, the two sliding holes 11 are both communicated with the inner cavity of the joint body 1, the hole walls of the two sliding holes 11 are both fixed with water blocking rings 111, and the water blocking rings 111 are elastic rubber rings.
Referring to fig. 2, the limiting blocks 4 are respectively slidably disposed in different sliding holes 11, one end of each limiting block 4 is provided with a guiding inclined plane 41, and the other end of each limiting block 4 is fixed with a moving block 42. The limiting block 4 is sleeved with a limiting tension spring 43, and the limiting tension spring 43 is used for driving the end part of the limiting block 4 to stretch into the inner cavity of the joint body 1. One end of the limit tension spring 43 is fixed on the outer wall of the joint body 1, and the other end of the limit tension spring 43 is fixed on the outer wall of the moving block 42 close to the joint body 1. When the limit tension spring 43 is in a natural state, the end part of the limit block 4 provided with the guide inclined plane 41 extends into the inner cavity of the joint body 1, the guide inclined plane 41 faces away from the mounting ring 2, and the end part of the limit block 4 provided with the moving block 42 is always positioned outside the joint body 1.
Referring to fig. 1 and 2, the unlocking ring 5 is slidably disposed on the joint body 1, the unlocking ring 5 includes a ring body 51 and an unlocking block 52 which are integrally formed, an unlocking inclined surface 521 is formed on the unlocking block 52, and the unlocking inclined surface 521 faces the moving block 42. The unlocking ring 5 is provided with a conduction groove 53, and the conduction groove 53 is used for the limiting block 4 and the limiting spring to penetrate through. Be fixed with two guide blocks 12 on the outer wall of joint body 1, the length direction of two guide blocks 12 all is unanimous with the sliding direction of unblock ring 5, has seted up two guide ways 511 on the inner wall of ring body 51, and two guide ways 511 all extend along the sliding direction of unblock ring 5, and guide ways 511 are used for supplying guide blocks 12 to slide the setting. The end part of the guide block 12 far away from the moving block 42 is fixed with a retaining block 13, and the retaining block 13 is used for limiting the movement of the ring body 51 to the guide block 12 and moving out of the guide groove 511.
Referring to fig. 2, the mounting ring 2 is provided with four ejection springs 21, and the ejection springs 21 are uniformly distributed along the axial lead of the joint body 1 in the circumferential direction.
