The rear card pipe fitting usually refers to the rear card sleeve in the dual card sleeve pipe joint, which is an important part of the card sleeve pipe joint. 

 Structural characteristics: 

 The cross-section shape of the rear clamp is similar to that of high heels. Its outer wall includes the front, middle and rear sections. The end of the front part is perpendicular to the axis, and the rear end is inclined to the front. The middle part of the outer wall includes three outer walls that are sunken to the axis, and the middle and rear of the inner wall is tilted outward. This unique geometry helps to produce a hinge-clamping effect, which can transform axial motion into radial extrusion on the clamp sleeve.
