[0025] See also Figure 6 , Figure 7 The positioning assembly 7 includes a circular ring 701 movably embedded in the upper end of the turntable 306, and a plurality of pointed cones 702 equidistantly distributed in a circle are arranged on the upper end of the circular ring 701, and the connection between the plurality of pointed cones 702 and the rubber ring 307 is a movable abutment, and the pointed cones 702 inserted into the rubber ring 307 can prevent the turntable 306 from rotating, and inclined links 703 are installed between the circular ring 701 and the plurality of horizontal links 603, and the cross-sectional shape of the inclined links 703 is circular, and connecting seats 704 are installed at both ends of the inclined links 703, and the inclined links 703 are movably hinged with the horizontal links 603 and the circular ring 701 through the connecting seats 704.

[0026] The working principle of being able to adjust the length of the drainage tube: the personnel press any two buttons 604 distributed on the same straight line to drive the two rubber blocks 601 to press against the triangular convex teeth 305 on the outside of the sleeve 304. In this process, since the inclined connecting rod 703 is movably hinged with the horizontal connecting rod 603 and the circular ring 701 respectively through the connecting seat 704, the two horizontal connecting rods 603 can drive the circular ring 701 to move downward inside the rotating disk 306 through the two inclined connecting rods 703 during the movement. The other rubber blocks 601 will also press against the triangular convex teeth 305 under the drive of the inclined connecting rod 703, so that the multiple pointed cones 702 are separated from the rubber ring 307. At this time, the brake of the rotating disk 306 is released. When the personnel rotate the turntable 306 through the two buttons 604 distributed on the same straight line, since the rubber block 601 abuts against the triangular convex teeth 305 on the outside of the sleeve 304, when the turntable 306 is rotated, the roller 303 will also rotate together, which is conducive to winding and storing the drainage tube 1 on the outside of the roller 303, and can adjust the length of the drainage tube 1 without affecting the drainage of the drainage tube 1, so as to prevent the drainage tube 1 with a long length from being squeezed by the patient when it is laid on the bed. When the personnel releases the button 604, the rubber block 601 and the ring 701 will move back and reset under the drive of the spring 605, and the pointed cone 702 will abut against the rubber ring 307 to prevent the turntable 306 and the rotating shaft 302 from rotating; Before rotating the winding roller 303, the personnel presses button 408 to disengage the stopper 405 from the embedding groove 404 on the U-shaped pin 403 and pull the U-shaped pin 403 out of the slider 402. Thereafter, the personnel puts the U-shaped pin 403 on the outside of the drainage tube 1 and then inserts it into the slider 402. During the insertion of the U-shaped pin 403, the U-shaped pin 403 is squeezed against the stopper 405 by the inclined surface of the stopper 405, so that the stopper 405 can automatically fit into the embedding groove 404. During the rotation of the winding roller 303 with the rotating shaft 302, the reciprocating screw rod 401 will rotate together with the rotating shaft 302 under the action of the synchronous wheel 9 and the synchronous belt 10, thereby driving the slider 402 and the U-shaped pin 403 to move back and forth up and down, which is conducive to driving the drainage tube 1 to be evenly distributed on the outside of the winding roller 303.

[0027] Embodiment 2 See also Figure 4 This embodiment further explains the first embodiment. Two symmetrically distributed coil springs 8 are fixedly installed on the outer side of the rotating shaft 302 corresponding to the inner side of the winding roller 303. The coil springs 8 can drive the winding roller 303 to rotate, and the outer end of the coil spring 8 is fixedly connected to the winding roller 303.

[0028] In this embodiment: after the person releases the button 2 604, the rubber block 601 disengages from the triangular convex tooth 305, and the roller 303 and the sleeve 304 can rotate on the outside of the rotating shaft 302. Since the two ends of the coil spring 8 are respectively connected to the rotating shaft 302 and the roller 303, when the rotating shaft 302 cannot rotate due to the positioning component 7, the roller 303 can rotate through the coil spring 8 to release a certain length of the drainage tube 1, thereby buffering the drainage tube 1 and preventing the drainage tube 1 from pulling the patient's wound when subjected to external force.

[0029] Embodiment 3 See also Figure 8 The present embodiment further explains the second embodiment, a tube holder 11 is fixedly installed on the outer side of the roller 303 near the lower end, a notch is opened on the outer side of the tube holder 11, the drainage tube 1 is movably connected to the tube holder 11 through the notch, a threaded sleeve 12 is movably sleeved on the outer side of the tube holder 11, and the threaded sleeve 12 is movably sleeved on the outer side of the drainage tube 1, a retaining ring 13 is fixedly sleeved on the outer side of the drainage tube 1 between the tube holder 11 and the threaded sleeve 12, a retaining rod 14 is fixedly embedded on the outer side of the roller 303, and the connection between the drainage tube 1 and the retaining rod 14 is movably abutted, and the retaining rod 14 can effectively prevent the drainage tube 1 from bending on the outer side of the roller 303.

[0030] In this embodiment: the personnel insert the drainage tube 1 into the tube holder 11 through the notch on the tube holder 11, and the retaining ring 13 is located at the lower side of the tube holder 11, and then the personnel install the threaded sleeve 12 on the outer side of the drainage tube 1 on the outer side of the tube holder 11, and fix the drainage tube 1 and the tube holder 11, so that the drainage tube 1 and the winding roller 303 are easy to disassemble and assemble, which is conducive to the regular replacement of the drainage tube 1 and the drainage bag 2, so that the winding structure 3 can be used multiple times, which can effectively reduce the use cost; When disassembling the drainage tube 1, the personnel first removes the U-shaped pin 403 from the slider 402 to disengage the drainage tube 1 from the U-shaped pin 403, then rotates the threaded sleeve 12 to disengage the threaded sleeve 12 from the tube holder 11, and then moves the drainage tube 1 out of the tube holder 11 through the notch on the tube holder 11. At this time, the drainage tube 1 can be quickly removed from the roller 303.
