[0041] In the embodiment: the first clamping part includes a sleeve 1 with a hollow structure at one end, the first pipeline interface 11 is arranged on the end wall of the closed end of the sleeve 1, and the first pipeline interface 11 communicates the inside and outside of the sleeve 1.
[0042] By embedding the connector 43 into the sleeve 1, a protective barrier is provided outside the connector 43, reducing the probability of objects outside the sleeve 1 touching the connector 43.
[0043] In the embodiment: the sleeve 1 is composed of two housings 12 arranged symmetrically, one of the housings 12 is provided with a plurality of threaded holes 121 facing a flat edge of the other housing 12;
[0044] The other housing 12 is provided with a plurality of through holes 122 corresponding to the plurality of threaded holes 121, and the threaded holes 121 are rotatably connected with the threaded holes 121, and the threaded ends of the threaded holes 121 are inserted into the corresponding threaded holes 121 and connected by threaded connection.
[0045] The two housings 12 are clamped by the parallel bolts 13, the relative rotation of the two housings 12 is limited, and the two housings 12 are connected to form an open-tube structure, so that the drainage tube 42 is clamped stably.

[0048] In the embodiment, the open end of the sleeve 2 is inserted into the open end of the sleeve 1 in a sliding fit, and the outer contour of the sleeve 2 is matched with the inner contour of the sleeve 1.
[0049] The outer contour of the sleeve 2 is matched with the inner contour of the sleeve 1, so that when the drainage tube 42 is connected to the sleeve 2, the sleeve 2 and the drainage tube 42 cover the opening of the sleeve 1 as a whole, the inside of the sleeve 2 and the inside of the sleeve 1 form a closed chamber, and the probability of bacterial contamination of the open ends of the two drainage tubes 42 is further reduced.
[0050] In the embodiment, the sleeve 2 is composed of a tubular body 22 having a hollow structure with two open ends and two clamping blocks 23 used for covering one open end of the tubular body 22, the open end of the tubular body 22 is inserted into the sleeve 1 in a sliding fit;
[0051] One of the clamping blocks 23 is fixedly connected to the end face of the tubular body 22 away from the sleeve 1, the two clamping blocks 23 are hingedly connected on the same side, the plane of the rotation track is perpendicular to the sliding track of the tubular body 22 in the sleeve 1, and the other two edges are detachably connected;
[0052] The two clamping blocks 23 are provided with semicircular notches 231 on the two facing planes, and the two notches 231 are connected to form the second pipeline interface 21.
[0053] Two clamping blocks 23 are used to clamp the drainage tube 42 on the patient. In use, when it is necessary to clamp the drainage tube 42 on the patient, the sleeve 2 is removed from the sleeve 1, and the two clamping blocks 23 are turned open to facilitate embedding the drainage tube 42 into the notch 231 on the clamping block 23, and then the two clamping blocks 23 are turned closed to clamp and fix the drainage tube 42 by extruding the drainage tube 42 through the surfaces of the two notches 231 on the two clamping blocks 23.
[0054] In the embodiment, a recess 232 is formed on the plane of one of the clamping blocks 23 facing the other clamping block 23, a locking block 233 is arranged in the recess 232, and one end of the locking block 233 protrudes from the opening of the recess 232 and is fixedly connected to the other clamping block 23.

[0056] The limiting pin 24 is arranged on the side wall of the recess 232 and is in close fit connection to limit the free sliding of the limiting pin 24 along the axial direction.
[0057] In use, when the two planes of the two clamping blocks 23 are pasted to each other, the two notches 231 on the two clamping blocks 23 are spliced to form a complete hole to clamp the drainage tube 42, at the same time, the locking block 233 is embedded in the recess 232, and the axis of the locking hole 2331 coincides with the axis of the limiting pin 24, so that the limiting pin 24 can be pushed into the locking hole 2331 or taken out of the locking hole 2331 by applying an external force along the axial direction of the limiting pin 24.
[0058] Under the hindering action of the side wall of the recess 232, the limiting pin 24 cannot move along the radial direction, but can only slide along the axial direction, so that after the limiting pin 24 is inserted into the locking hole 2331, the limiting block is limited to move out of the recess 232, to limit the turning of the two clamping blocks 23 to open the notches 231, so that the two clamping blocks 23 can continuously and stably clamp the drainage tube 42. After the limiting pin 24 is removed from the locking hole 2331, the hindering action of the limiting pin on the block disappears, so that the two clamping blocks 23 can relatively rotate to open the notches 231 to facilitate the drainage tube 42 to move out of or be installed and embedded in the notches 231.
[0059] In the embodiment, a sliding groove 14 extending along the length direction of the sleeve 1 is formed on the inner side wall of the sleeve 1, a rack 25 is in sliding fit in the sliding groove 14, and the side of the rack 25 away from the teeth is fixedly connected to the outer side wall of the sleeve 2.

[0061] The sleeve 1 is fixedly connected to the hinge seat 15 on the side wall of one end facing the sleeve 2, and the gear wheel 3 is coaxially rotatably connected to the hinge shaft in the hinge seat 15.
[0062] In use, when the joint 43 needs to be inserted into the opening of the other drainage tube 42, the gear wheel 3 is reversely rotated, the gear wheel 3 applies a pushing force to the gear rack 25 along the length direction of the sleeve 1, the gear rack 25 drives the sleeve 2 to slide out of the sleeve 1, then the sleeve 1 clamps the drainage tube 42 in the drainage bag away from the collecting bag 41, and the joint 43 is embedded in the sleeve 1, then the sleeve 2 clamps the drainage tube 42 on the patient's body away from the body, and the port of the drainage tube 42 is embedded in the sleeve 2, the gear wheel 3 is forwardly rotated, the gear wheel 3 drives the sleeve 2 to move into the sleeve 1 through the gear rack 25, the joint 43 is relatively close to the other drainage tube 42, the axis of the first pipe interface 11 is coincident with the axis of the second pipe interface 21, the joint 43 is aligned with the opening of the other drainage tube 42, and the opening end of the joint 43 is inserted into the opening of the other drainage tube 42, the gear wheel 3 is continuously forwardly rotated, and the joint 43 and the other drainage tube 42 are pressed against each other, so that the connection of the two drainage tubes 42 is more firm.
[0063] Further, the maximum stroke of the sleeve 2 moving in the sleeve 1 is fixed, the stroke of the relative movement of the two drainage tubes 42 is relatively stable, the phenomenon that the drainage tube 42 on the patient's body is pulled with a large amplitude is avoided, and the probability that the patient's wound is secondarily injured is reduced.
[0064] In the embodiment, the gear wheel 3 is provided with a lever 31, one end of the lever 31 is fixedly connected to the outer circular surface of the gear wheel 3, and the other end extends radially towards the gear wheel 3.
