When the pressing fastener 30 is in the locking position, the clamping portion 32 extends into the second flow channel 22 and clamps into the annular groove 12 to fix the first tube 11 (as shown in FIG. Figure 4 As shown), the first connector 10 and the second connector 20 are in a joined state.

[0031] Please refer to " Figure 3 "and" Figure 4” As shown, the push rod 40 has a top 41, a bottom 42 and a neck 43, the neck 43 is located between the top 41 and the bottom 42, the length of the neck 43 is greater than the thickness of the push buckle 30, and the neck 43 has a first neck surface 431 and a second neck surface 432, the neck thickness of the first neck surface 431 is less than the neck thickness of the second neck surface 432, the first neck surface 431 is connected to the top 41, and the second neck surface 432 is connected to the bottom 42. Preferably, the first neck surface 431 and the second neck surface 432 are connected via a connecting inclined surface 433.

[0032] Please refer to " Figure 4 "and" Figure 5 ” as shown, the bottom 42 of the push rod 40 is slidably disposed in the axial sliding groove 212 with a push spring 60 therebetween, and the neck 43 is clamped into the clamping groove 33 and restricted to slide on the clamping groove 33, and when the pressing fastener 30 is in the locked position, the radial width of the clamping groove 33 facing the neck 43 is between the neck thickness of the first neck surface 431 and the neck thickness of the second neck surface 432, and when the pressing fastener 30 is in the unlocked position, the width of the clamping groove 33 facing the neck 43 is greater than the neck thickness of the second neck surface 432.

[0033] As described above, when the push fastener 30 is in the locked position, the second neck surface 432 cannot penetrate into the slot 33 (eg, Figure 4 When the operator presses the pressing fastener 30, the pressing fastener 30 can slide relative to the radial slot 211, so that the pressing fastener 30 is changed from the locking position to the unlocking position (as shown in FIG.
