The working principle is as follows: when a patient with severe symptoms needs to be fixed, a nurse manually rotates the rotating plate 21 until the rotating plate 21 cannot rotate, at the moment, the rotating plate 21 and the limb of the patient are kept in a vertical state, then the threaded rod 22 rotates to drive the moving block 23 to move, the moving block 23 moves to drive the clamping blocks 25 to move, so that the positions of the clamping blocks 25 can be adjusted according to the actual limb positions of the patient, when the limb of the patient is fixed, the lead screw 24 rotates to drive the two clamping blocks 25 to move, the two clamping blocks 25 approach each other after moving to clamp and fix the limb of the patient, and when the limb of the patient is fixed and stable, the nurse controls the lead screw 24 to stop rotating;

when two grip blocks 25 move to nearest patient's limbs and can't be fixed stably, nurse control pivot 271 rotates, pivot 271 rotates and drives line wheel 272 and rotate the in-process and can carry out the rolling to stay cord 273, under leading wheel 274 and guide bar 275's cooperation guide effect, stay cord 273 can drive sealed piece 277 by the in-process of rolling and move, sealed piece 277 moves the in-process and can extrude the inside gas of air cavity 278, make gas enter into the packing intracavity portion that forms between cortex membrane 26 and the grip block 25, along with gaseous the letting in, cortex membrane 26 is propped up the limbs fully contact with patient gradually, thereby can assist fixedly to patient's limbs, just so can carry out more stable fixed to patient's limbs.

In the fixing process, when the patient feels restless, the limbs of the patient move in disorder and drive the rubber cylinder 41 to move, the second spring 46 is compressed in the moving process of the rubber cylinder 41, when the limbs of the patient move and loosen the extrusion on the rubber cylinder 41, the rubber cylinder 41 moves outwards under the action of the resilience force of the second spring 46, so that the rubber cylinder 41 can move in a reciprocating manner in the disorder process, the connecting rod 43 can be driven to move in a reciprocating manner when the rubber cylinder 41 moves in a reciprocating manner, the bar magnet 44 can be driven to move in a reciprocating manner during the reciprocating movement of the connecting rod 43, the bar magnet 44 can continuously enter and exit from the inside of the spiral coil 45 in the reciprocating movement process, the magnetic flux in the spiral coil 45 changes and generates current in the process of entering the inside of the spiral coil 45, the spiral coil 45 can electrify the first spring 42 after generating current, after the bar magnet 44 comes out of the spiral coil 45, the current stops being generated inside the spiral coil 45, so that the first spring 42 is not electrified any more, the first spring 42 contracts when being electrified, and resets after the first spring 42 is powered off, so that the first spring 42 continuously compresses and resets, and vibrates discontinuously to drive the rubber sleeve 41 to vibrate, and the fixed part of the limb of the patient is massaged in the vibration process of the rubber sleeve 41, so that the discomfort of the fixed position of the limb of the patient is greatly reduced, the mood of the patient can be changed and soothed, and the restlessness of the patient can be relieved;

when current is generated in the spiral coil 45, the electromagnet 473 is also electrified, after the electromagnet 473 is electrified, magnetism is generated to attract the iron block 472 and drive the iron block 472 to move, the iron block 472 stretches the spring 471 in the moving process, meanwhile, the power connection block 474 is driven to move, the power connection block 474 contacts the power supply block 475 in the moving process, the power connection block 474 is electrified after contacting the power supply block 475 and energizes the fan 476, the fan 476 rotates after being electrified, wind generated by the fan 476 enters the air blowing pipe 478 through the wind groove 477 and is sprayed out of the bottom of the air blowing pipe 478, thereby blowing the fixed part of the limb of the patient, avoiding the occurrence of the condition that the fixed part of the limb of the patient generates dryness heat in summer to cause larger mood fluctuation of the patient, therefore, the discomfort of the patient during the fixation can be greatly reduced, and the comfort of the fixation device in the use process is better.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
