the second connector 2 comprises in sequence: the insertion part 21, the guide part 22 and the limiting part 23, wherein a limiting block 3 is welded between the guide part 22 and the limiting part 23;
when the second connector 2 is inserted into the first connector 1, the position of the limit block 3 corresponds to the balls 4, the width D of the limit block 3 in the circumferential direction is smaller than the linear distance D between two adjacent balls, the distance H1 between the radial direction and the axis of the limit block 3 is greater than the minimum distance H2 between the balls and the axis, and the distance H1 between the radial direction and the axis of the limit block 3 is smaller than the inner diameter R1 of the first connector 1.
As shown in fig. 1 or fig. 2, a limiting step 51 is arranged in the middle of the inner side of the ferrule 5, and a first yielding space 501 and a second yielding space 502 are formed between the front end and the rear end of the limiting step 51 and the first connecting body 1. The first abdicating space 501 is used for abdicating the ball 4; the first spring 6 is arranged in the second abdicating space 502, and the first spring 6 can be compressed through the limiting step 51.
Further, as shown in fig. 2, in order to restrict the position of the snap ring 9 and prevent the snap ring 9 from coming out of the central hole of the first coupling body 1, an inner step 12 is provided at one end of the first coupling body 1.
As shown in fig. 2, in the initial state, at this time, the snap ring 9 pushes against the inner step 12, the ball 4 is pressed into the first abdicating space 501, the second spring 8 is in the open state, and at the same time, the ferrule 5 is pressed by the ball 4 and contracts backwards, and the first spring 6 is in the locked state.
As shown in fig. 1, after the second connection body 2 is inserted into the first connection body 1, the insertion portion 21 of the second connection body 2 presses the snap ring 9, so as to compress the second spring 8, at this time, the ball 4 pops out and leaves the first abdicating space 501, the ferrule 5 is under the tension of the first spring 6 due to lack of the limit of the ball 4, and moves forward, the ball 4 is pushed up by the limit step 51 of the ferrule 5, at this time, due to the limit of the ball 4, the guide portion 22 of the second connection body 2 is located between the ball 4 and the snap ring 9, and is immovable, and the second connection body 2 and the first connection body 1 are connected in place.
