For another example Figure 30 and shown in Figure 31, when water pipe T is subject to crooked application of force Fc and during by bending, although the ring flange 46 of corresponding bending direction breach groove 51 locational elastic clip Button Blocks 40 can't be subject to the support of buckle pad 50, be subject to 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 (as shown in figure 30) of larger clearance G 2, but, the original fixed jack 104 of plant pipe joint body 100, water pipe T in the interior annular distance of sealing O circle 20 and the interior annular distance 61 of retaining ring 60, then because of the support that is coated and fixed of the interior annular distance 61 that is subject to retaining ring 60, and can not come sealing O circle 20 is produced the again phenomenon of 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) therefore make simultaneously sealing O enclose 20 original equivalent distortion, therefore, no matter the crooked application of force Fc direction of water pipe T is crooked towards beyond, all because being subject to the clamping effect of retaining ring 60, do not seal the even sealed effect that O encloses 20 pairs of water pipe T outer tube walls and can not affect, relatively, the interior high pressure water P of water pipe T that flows through also can seepage go out because no longer including the relatively poor approach of sealing, and the outside (as shown in figure 30) of elastic clip Button Blocks 40 can not occur to flow out via the penetration hole 44 of elastic clip Button Block 40, more do not have in the circuit connection of infiltrating in the Hyperfilevation water purifying machine or the disappearance in the suction booster.

In sum, when the utility model is got 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 a greatly innovation to the great inserting type pipe joint of usage quantity, and has industrial applicability.
