The second latch 34 has substantially the same structure as the first latch 33, and also includes a second connector 341 and a second latch 342 disposed on the second connector 341. The only difference is that the angle between the abutting surface of the second snap joint 342 abutting against the snap ring 21 of the male joint 20 and the central axis of the first barrel 11 has an acute angle, and after the male joint 20 is inserted into the locking member 30, the abutting surface extends away from the snap ring 21. The operating principle of the second chuck connector 342 configured as such will be described in detail below.

The release catch 40 includes a fixed cylinder 41 fixed in the first cylinder 11, a positioning cylinder 42 connected to the fixed cylinder 41 along the axial direction of the first cylinder 11, and two release pieces 43 disposed on the fixed cylinder 41, the fixed cylinder 41 is inserted into the first cylinder 11, in order to fix the fixed cylinder 41, at least three insertion blocks 411 respectively engaged with the insertion holes 112 are disposed on the outer side wall of the fixed cylinder 41, in order to insert the fixed cylinder 41 into the first cylinder 11, a gap 412 is disposed on the side wall of the fixed cylinder 41, the fixed cylinder 41 having the insertion blocks 411 is inserted into the first cylinder 11 of the female joint 10 when the gap 412 is closed, the insertion blocks 411 are inserted into the insertion hole 112 when the gap 412 is restored, the fixed cylinder 41 is further provided with at least two relief holes 413 when the male joint 20 is inserted into the female joint 21, the first joint 332 passes through the relief hole 413 to be caught on the retaining ring 21 when the male joint 20 is inserted into the fixed cylinder 21, the retaining ring 21, the retaining head is positioned on the outer diameter of the fixed cylinder 41, the retaining ring 21, the retaining head is positioned on the outer diameter of the retaining ring 41, and the retaining ring 21, when the retaining head is restored to the retaining ring 31, the retaining ring 21, the retaining ring 32, the retaining head is positioned, the retaining ring 21, the retaining ring 32, the retaining ring is pressed to be positioned on the retaining ring 21, the retaining ring 32 is pressed to be positioned to be inserted into the retaining ring 21, the retaining ring 32 is pressed to be positioned to be inserted into the retaining ring 21, and to be positioned to be inserted into the retaining ring 21, the retaining ring 32, the retaining ring 21, the retaining ring 32, the retaining ring 21, the retaining ring 32 is pressed to be positioned to be inserted into the retaining ring 21, and the retaining ring 21, the retaining ring 32, the retaining ring 21, and the retaining ring 32, the retaining ring 32 to be positioned.

After the male connector 20 is inserted and the medium is introduced, the male and

female connectors

10, 20 will move in the direction of separating from each other under the pressure of the medium, at this time, the right-angle groove 333 of the first locking member 33 will abut on the unlocking buckle 40, and the ring body 31 will be separated from the step formed by the first and

second cylinder bodies

11, 12. At this time, all or part of the propping head 432 is located right above the pressing member 32. Therefore, when the supporting head 432 is pressed down, the pressing member 32 is not driven to rotate, and the pressing member 32 is prevented from being rotated to open the first fastener 33 in case of misoperation.

When the unlocking is required, the male joint 20 needs to be pressed against the ring body 31 under the action of an external force so as to be pressed against the step formed by the first and

second cylinder bodies

11 and 12, so that the inclined surface 433 of the supporting head 432 and the pressing member 32 are arranged in a staggered manner, and when the supporting head 432 of the unlocking member 40 is pressed, the inclined surface 433 of the supporting head 432 presses against the pressing member 32, so that the first buckling member 33 is tilted in a direction away from the male joint 20 so as to separate the first buckling member 332 from the abutting with the buckling ring 21 of the male joint 20. Therefore, in order to tilt the first latch 33 when the pressing member 32 is pressed, two pressing members 32 are respectively arranged with the two first latches 33 along the central axis of the first cylinder 11. Meanwhile, an included angle between an abutting surface of the second snap joint 342 abutting against the snap ring 21 of the male joint 20 and a central axis of the first cylinder 11 has an acute angle, that is, it is an inclined surface. When the first engaging portion 332 is disengaged from the engaging ring 21 and the male connector 20 is pulled out, the second engaging portion 342 is spread so that the male connector 20 can be pulled out.

In order to position the unlocking element 40 and the locking element 30, a guide block 334 is disposed inside two first fasteners 33 spaced from the pressing element 32, and two guide grooves 421 respectively engaged with the guide block 334 are disposed on the outer side wall of the positioning cylinder 42.
