The working principle is as follows: when the device is required to wind and store the wire 115, only one group of fixture blocks 214 needs to be pulled to one side respectively, so that the first spring 215 deforms, the fixture blocks 214 move upwards, then each group of wires 115 are placed on one side inside each group of fixture blocks 214 respectively, then the fixture blocks 214 are loosened, the first spring 215 recovers deformation, the fixture blocks 214 limit the wires 115, then the middle sides outside the wires 115 are placed on the side released from the fixture blocks 214, the wires 115 on two sides of the fixture blocks 214 are placed on the same side, then the winding shaft 212 is rotated, the wires 115 on two sides of each fixture block 214 are wound on the outside of the winding shaft 212 by the winding shaft 212, the probe main body 116 is placed inside the placing block 220, and finally the bolt 218 is rotated to abut against the winding shaft 212, so that fixing is completed.

When the utility model is needed, the bolt 218 is rotated counterclockwise first, the bolt 218 is released from the contact with the winding shaft 212, then the rotating rod 419 is rotated, the second bevel gear 420 is rotated when the rotating rod 419 is rotated, so that the first bevel gear 417 is rotated, the transmission shaft 414 is rotated when the first bevel gear 417 is rotated, so that the transmission gear 415 is rotated, when the transmission gear 415 is rotated, the two sets of rack plates 416 are positioned at the two sides of the transmission gear 415, so that the two sets of rack plates 416 are separated from each other, when the two sets of rack plates 416 are separated from each other, the two sets of first movable rods 411 are driven to be separated from each other, so that the limiting block 314 is separated from the limiting groove 316, and simultaneously, the second spring 313 is deformed, then the fixed bottom plate 211 is pulled to one side, so that the fixed bottom plate 211 can be removed, at this time, the conducting wire 115 is wound outside the winding shaft 212, when the fixing base plate 211 is pulled, the wire 115 may partially unwind the wire 115 at both sides of the latch 214.

The sick bed upper end is laminated with the one end of PMKD 211 afterwards, promote to the one side that is close to the sick bed afterwards and make movable clamp plate 513 and sick bed butt, thereby make movable clamp plate 513 downstream, make third spring 514 take place deformation simultaneously, continue to promote when connecting one side of bottom plate 511 and sick bed edge butt, can stop promoting, third spring 514 is in deformation state this moment, thereby make movable clamp plate 513 and sick bed downside closely laminate, thereby accomplish fixedly, when needs remove, only need to keep away from one side pulling PMKD 211 of sick bed can, because wire 115 both sides all are in not hard up state, can pull probe main part 116 to patient's limbs on carry out the fixed inspection, after the inspection is accomplished, only need take off PMKD 211, rotate winding shaft 212 again afterwards and accomodate wire 115 both sides.

When the rotation of the rotating lever 419 is stopped, the second spring 313 is deformed again, so that the stopper 314 is restored to the original position, and then the inserting plate 315 is inserted into the fixing base 112, so that the stopper 314 enters the inside of the stopper groove 316 again, thereby restoring the fixing.

When the plug 114 is inserted into the device main body 111, the plug 114 is abutted against the abutting blocks 614 on the two sides, so that the abutting blocks 614 on the two sides are away from each other, and the fourth springs 613 deform, when the plug 114 enters the fixing base 112, the plug 114 is placed on one side of the abutting blocks 614, at the moment, the two sets of fourth springs 613 deform again, so that the abutting blocks 614 limit the other side of the plug 114, and protection is performed.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
