The ratchet 82 is coaxially mounted on the shaft 16. One end of the scroll spring 83 is fixed to the scroll spring fixing plate 9, and the other end of the scroll spring 83 is connected to the rotating shaft 16. The shaft 16 can rotate about its central axis in a manner that the volute spring 83 contracts or expands.

Preferably, the partition plate 3 and the scroll fixing plate 9 are parallel to each other with both end surfaces in the longitudinal direction of the housing 1. The inside in wire storage area is equipped with pawl fixing base 7. The pawl 81 is connected to a first end of the pawl holder 7 in a hinged manner. A first end of the pawl 81 abuts against the ratchet 82, wherein: in the case where an external force acts on the pawl 81, the first end of the pawl 81 can abut against or disengage from the ratchet gear 82 in such a manner as to rotate about the hinge point of the pawl 81 with the first end of the pawl holder 7. For example, the stored energy compressed by the previous volute spring 83 powers the automatic retraction of the wire, and when the wire needs to be retracted, the pawl 81 is rotated by rotating the pin 6 to disengage the first end thereof from the ratchet 82, and at this time, the previously stored elastic potential energy of the volute spring 83 is released and converted into kinetic energy for rotating the shaft 16 and the components fixed to the shaft 16. At this time, the lead wire 17 to be housed is wound on the reel 10 with the reel 10 rotating, enabling automatic housing of the lead wire.

Preferably, the reel 10 is provided on the rotating shaft 16, and the signal relay barrel 12 is mounted inside the reel 10 in a nested manner. The end of the signal transfer barrel 12 remote from the reel 10 is fixed to a bracket plate 13.

The surface of the reel 10 is provided with input lead fixing holes 11 uniformly at equal intervals in such a manner as to extend in the axial direction thereof.

Preferably, the signal transfer barrel 12 is a hollow cylindrical barrel, a wire 14 is arranged on the signal transfer barrel 12, and the wire 14 is connected to the electrocardiograph monitoring module 2 in the electrocardiograph monitoring area in a manner of penetrating through the partition plate 3. The electrocardiograph monitoring module 2 can be any type of electrocardiograph monitor with an external lead, which is clinically applied at present.

Preferably, an input wire guide 4 is provided in the wire housing area along a side surface in the width direction of the housing 1. One end of the lead wire 17 to be received extends to the outside of the housing 1 in such a manner as to penetrate the input lead wire hole 4.

A spring 52 is mounted in a nested manner in the region of the control rod 54 delimited by the stop 51 and the shoulder 53. In the case where the control lever 54 is slid in the axial direction thereof toward the stopper 51, the spring 52 can be shortened in length in such a manner that energy is stored under compression of the shoulder 53 and the stopper 51. Under the condition that the control rod 54 is not subjected to an external axial force, the spring 52 can drive the control rod 54 to slide along the axial direction thereof away from the limiting block 51 in a manner of pushing the shoulder 53. The spring 52 here acts as an automatic return.

Preferably, the control rod 54 is provided with a control button 55 at one end thereof extending through to the outside of the housing 1.

Preferably, the other end of the control rod 54 is connected to the second end of the pawl 81 in an articulated manner, wherein: with the control button 55 depressed, the first end of the pawl 81 can disengage the ratchet gear 82 in a manner that rotates about the hinge point of the pawl 81 with the first end of the pawl holder 7. The purpose of this design is to control the automatic wire take-up mechanism by changing the position of the lever 54 to bring the pawl 81 into and out of contact with the ratchet 82.
