The utility model relates to pipeline connection technical field, and disclose a kind of pipeline connection assembly structure for pipeline fitting, including first installation ring, the middle threaded connection of first installation ring inner wall has threaded rod, the bottom end fixedly connected with handle of threaded rod.This pipeline connection assembly structure for pipeline fitting, through the mutual cooperation of handle, threaded rod, bearing, crosspiece, limit block, rubber pad and telescopic rod of being set, to realize the effect of the fixed pipeline, by rotating handle to drive the rotation of threaded rod, to drive the rotation of bearing, to facilitate the up-down movement of crosspiece, to drive the telescopic of telescopic rod, to facilitate the limit block to be moved to the outer side wall of pipeline, to facilitate the fixed clamping of pipeline, by rubber pad to increase the friction between pipeline, to be fixed as much as possible more fastening, to avoid the risk of pipeline falling during work as much as possible.

This application discloses a flexible bag with chain teeth, comprising: fabric, core thread, sewing thread, and multiple chain teeth; the fabric includes a fabric body, a pleated edge, and a connecting portion, the pleated edge conforming to the edge region of the fabric body, and the connecting portion connecting between the edge end of the fabric body and the edge end of the pleated edge; the connecting portion has a thread channel, through which the core thread passes; the sewing thread is sewn onto the fabric and locks the connecting portion, thereby tightly wrapping the core thread through the connecting portion; multiple chain teeth are arranged along the extension direction of the core thread, and each chain tooth is connected to the area of ​​the connecting portion of the fabric. This application can at least solve problems such as the core thread being not secure.

This invention relates to the field of surgical scaffold technology, and more particularly to a pressure shaping device for surgical bone injuries, comprising a first flipping block and a second flipping block. The first flipping block is rotatably connected to the outer wall of the second flipping block via a rotating shaft. A limiting component is provided on the first flipping block to change the rotation angle of the second flipping block. This invention, through its adjustable component, allows the air bladder to inflate and conform to the patient's leg, thereby adapting to the physiological curvature of the leg and avoiding the difficulty of achieving a proper fit based on the specific shape of the patient's leg in existing technologies. A pressure sensor monitors the shaping pressure; when the pressure sensor's detection value is below a threshold range, the air bladder further inflates, ensuring that the air bladder always remains in contact with the patient's leg and applies a certain shaping pressure. Compared to existing shaping methods that apply fixed pressure using straight plates or simple curved structures, this invention avoids the weakening of shaping pressure due to the reduction of swelling in the patient's leg.
