Guard circle 3.The external annulus for circumferentially pushing away circle 4 contact with pushing away the inwall of circle guard circle 3.The external annulus of linkage section 52 are with pushing away circle guard circle
3 inwall is in contact, and free gap 31 is left between the external annulus of active section 51 and the inwall for pushing away circle guard circle 3.
The external annulus of sealing ring retainer plate 7 are provided with recess 70, and the opening of junction 2 is provided with the flanging of inner side
24.Push away the one end for enclosing guard circle 3 and flanging 24 is inconsistent, the other end extends at recess 70 and inconsistent with recess 70.So
Secure and push away circle retainer plate 3 in the position of the inner side of junction 2.
Push away circle guard circle 3 and the inner ring of the inconsistent end of flanging 24 is provided with bulge-structure 30, circumferentially push away the external annulus of circle 4
The stopper slot 40 being engaged with bulge-structure 30 is provided with, as shown in Figure 2 and Figure 6.The axial width of bulge-structure 30 with it is spacing
The axial depth of groove 40 is consistent.The so circumferential circle 4 that pushes away just has been limited in inside pipe joint.Circle 4 is circumferentially pushed away with pushing away circle protection
The end face of circle 3 is flush, it is necessary to could be opened using special instrument, is avoided that and is extruded in the prior art because rubber sleeve hardens
Movable sleeve causes body to be loosened with pipe joint, causes the phenomenon of leak.
Operation principle of the present utility model is：It is engaged, is rotated with the circumferential breach for pushing away 4 end faces of circle using special instrument
Circle 4 circumferentially is pushed away, projection 42 thereon is moved along inclined-plane, during projection 42 moves, axially pushes away circle 5 towards provided with card
The side movement of circle 6, and contacted with latch 60, during force, latch 60 is gradually elapsed toward outside, expands uniform point
The diameter for the inner ring that the latch 60 of cloth is formed, at this moment body can stretch into or remove.Reversely rotate again and circumferentially push away circle 4, it is circumferential
Push away the projection 42 on circle 4 gradually to move toward the minimum point of spill mouth 5, be applied to the power axially pushed away on circle 5 and disappear, axially push away circle 5
Gradually reset, latch 60 is also gradually brought to reset condition.
