the working principle is as follows: when the device works, the worker splices and combines the device into a cylindrical wrapping structure, so that the hook plates 105 are hooked and connected inside the corresponding second snap rings 202, then the worker sleeves and wraps the device outside the fractured limb and the fracture affected part needing to be fixed by a patient, the two ends of the connecting band 301 are respectively inserted into the second snap rings 202, the hook and loop surfaces 303 are adhered to the hook and loop surfaces 302 by turning over, and the device is connected between the two groups of side clamping plate pieces 200 by the connecting mechanism 300;

when the device works, a worker drives the cross rod 406 to rotate through the rotating handle 407, the two groups of winding rollers 402 rotate synchronously and oppositely by means of meshing transmission between the worm 405 and the worm wheel 404 and matching with the meshing transmission between the two groups of gears 403, and the stretching belt 103 wound and wrapped on the outer side of the winding rollers 402 is rotated and tightened through the rotation of the winding rollers 402, so that the device is gradually tightened and fixed on the outer side of the injured position of a patient;

when the device works, when the cross rod 406 rotates, the disc 607 fixed on the outer side of the left end of the cross rod is driven to rotate, the rocker 608 is driven to swing up and down in a reciprocating cycle through the disc 607, the push rod 603 moves up and down in the medicine tube 601 in a circulating mode under the pulling action of the rocker 608, so that the valve plate 602 moves up and down in the medicine tube 601 in a reciprocating mode, alcohol enters the medicine tube 601 from the liquid inlet tube 605 in the alcohol storage box 700 under the action of air pressure and is extruded and conveyed to the inside of the axle tube 502 through the liquid outlet tube 604 in the medicine tube 601, the alcohol is soaked into the sponge brush roller 504 through the through hole 503 formed in the outer wall of the axle tube 502, and the sponge brush roller 504 is driven to rotate by means of contact friction resistance in the moving process of the stretching belt 103, so that the overall and delicate alcohol brushing disinfection operation is performed on the outer surface of the stretching belt 103;

when the device works and in subsequent continuous rehabilitation, a worker needs to slowly adjust the fixing tightness of the device on the limbs of a patient according to the rehabilitation effect, the worker drives the cross rod 406 to rotate through the reverse rotation handle 407, the two groups of winding rollers 402 synchronously and reversely move by means of the meshing transmission between the worm 405 and the worm wheel 404 and the meshing transmission between the two groups of gears 403, the stretching belts 103 wrapped on the outer sides of the winding rollers 402 are slowly and gradually released through the rotation of the winding rollers 402, and therefore the wrapping tightness of the device is adjusted.
