Figure 30 and shown in Figure 31 for another example; When water pipe T receives crooked application of force Fc and during by bending; Though the ring flange 46 of corresponding bending direction breach groove 51 locational elastic clip Button Blocks 40 can't receive the support of buckle pad 50; Receive edge surface 43 that crooked application of force Fc makes use and form with the wall surface of the hole of round tube hole 33 and contact fully and still can occur in; And the edge surface 43 of making use away from crooked application of force Fc and the wall surface of the hole of round tube hole 33 then form the state (shown in figure 30) of bigger clearance G 2; But the water pipe T in the interior annular distance of the fixed jack 104 of the pipe joint body 100 of planting originally, sealing O circle 20 and the interior annular distance 61 of retaining ring 60 is then because of the support that is coated and fixed of the interior annular distance 61 that receives retaining ring 60; And the phenomenon that can not come sealing O circle 20 is produced again unequal extruding application of force F1 along with the crooked application of force Fc direction of water pipe T; Still be not changed (shown in the distortion of the equivalent in the zoomed-in view among Figure 30 section 22) so make sealing O enclose 20 original equivalent distortion simultaneously, therefore, no matter the crooked application of force Fc direction of water pipe T is crooked towards beyond; All because of receiving the clamping effect of retaining ring 60; And can not influence the even sealed property effect that sealing O encloses 20 pairs of water pipe T outer tube walls, relatively, the high pressure water P in the water pipe T that flows through also can seepage go out because of no longer including the relatively poor approach of sealing; And the outside (shown in figure 30) that elastic clip Button Block 40 can not take place to flow out via the penetration hole 44 of elastic clip Button Block 40 does not more have in the circuit connection of infiltrating in the reverse osmosis water purifier or the disappearance in the suction booster.

In sum, when the present invention gets rid of water pipe T bending with a retaining ring 60 very dexterously, make inserting type pipe joint produce the disappearance of percolating water, it is an innovation greatly to the great inserting type pipe joint of usage quantity, and has industrial applicability.
