However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

The rotating rod 25 is arranged inside the winding box 21. Six groups of through holes 12 are opened through the front and rear ends of the winding box 21. One ends of the six signal lines 11 are respectively inserted into the six groups of through holes 12, and each signal line 11 is respectively wound around the two groups of U-shaped plates 27. One end of the rotating rod 25 passes through one end of the winding box 21 and is fixed to one end of the round seat 24. The other end of the rotating rod 25 passes through the other end of the winding box 21 and is rotatably installed inside the matching seat 23.

[0023] The specific configuration and function of this embodiment are described in detail below. By rotating the rotating handle 22, the rotating handle 22 drives the rotating rod 25 to rotate, and the rotating rod 25 drives the plurality of fixed plates 26 to rotate inside the winding box 21. At the same time, the plurality of fixed plates 26 respectively drive the upper and lower U-shaped plates 27 to rotate, so that the plurality of U-shaped plates 27 rotate inside the winding box 21, and the two ends of the six signal lines 11 are respectively pulled into the winding box 21 from the plurality of through holes 12, so that the six signal lines 11 can be wound up, and the six signal lines 11 are wound up to the winding box 21. The inside of the winding box 21 will not hinder the operation of the staff, and will not affect the operation speed of the staff, so that the detection speed can be guaranteed. At the same time, it prevents the six signal lines 11 from being entangled or knotted, and ensures that the signal can be transmitted normally. By setting a plurality of sets of baffles 28, when the plurality of sets of U-shaped plates 27 rotate, the plurality of sets of U-shaped plates 27 will respectively drive the two sets of baffles 28 fixed thereto to rotate together, which can prevent the signal line 11 from detaching from the U-shaped plate 27 when winding, so that the signal line 11 can be freely retracted and released later;

[0024] Secondly, the 8-to-1 analog switch CD4051 is used to connect and disconnect the signal;

[0025] ADC is an analog-to-digital converter, or A / D converter, which usually refers to an electronic component that converts analog signals into digital signals;

[0026] The function of the acceleration sensor is to obtain the acceleration value by measuring the inertial force exerted on the mass block during the acceleration process using Newton's second law;

[0027] The switching controller is used to switch between different power input devices, which can achieve many functions;

[0028] By placing six sets of ECG detection probes 1 at specific positions on the patient's body and running the electrocardiograph, the six sets of ECG detection probes 1 placed on the body surface are used to capture cardiac electrical signals and convert them into weak electric currents, which are then transmitted to the inside of the junction box through six signal lines 11. With the cooperation of the 8-to-1 analog switch CD4051, the acceleration sensor and the switching controller inside the junction box, the signals are accurately transmitted to the ADC and converted into digital signals at the ADC, which are then transmitted to the electrocardiograph. The electrocardiograph will amplify the electrical signals and display them in a graphic. This graphic is usually displayed in the form of multiple waveforms, such as P wave, QRS complex and T wave. The doctor will judge whether the electrical activity of the heart is normal based on the characteristics of the waveform shape, period, amplitude and duration on the electrocardiogram. Example

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the fixing mechanism 3 includes a fixing block 31, a pulling block 32 is provided at the upper end of the fixing block 31, a limiting hole 33 is penetrated by the pulling block 32 and one end of the round seat 24, a circular hole 36 is penetrated by one end of the pulling block 32 and near the edge positions on both sides, an insertion rod 34 is welded at the lower end of the pulling block 32 and near the edge positions on both sides, a limiting rod 35 is welded at the middle position of the lower end of the pulling block 32, one end of the pulling block 32 is fixed to one end of the winding box 21, two groups of insertion rods 34 are respectively inserted into the inside of the two groups of circular holes 36, and the limiting rod 35 is inserted into the inside of the circular hole 36.

[0030] The effect achieved by the entire embodiment is that, by providing a fixing mechanism 3, the fixing block 31 is picked up, the limiting rod 35 at one end of the fixing block 31 is inserted into the limiting hole 33, and the fixing block 31 is pushed to move, and at the same time, the fixing block 31 will also drive the two groups of plug rods 34 fixed thereto to move, so that the two groups of plug rods 34 are respectively inserted into the two groups of circular holes 36, and the limiting rod 35 will be completely inserted into the limiting hole 33, and then the turning handle 22 can be fixed, thereby preventing the turning handle 22 from rotating when the signal line 11 is pulled, and preventing the signal line 11 from being pulled out from the inside of the winding box 21 by external force.

[0031] The method of use and working principle of the device: First, when in use, by picking up the fixing block 31, the fixing block 31 drives the two groups of insertion rods 34 and the limiting rods 35 fixed thereto to move, so that the two groups of insertion rods 34 are respectively taken out from the inside of the two groups of limiting holes 33, and the limiting rods 35 are moved out from the inside of the limiting holes 33 to contact the fixing of the rotating handle 22;

[0032] The staff pulls the six signal wires 11 so that the six signal wires 11 drive the two groups of U-shaped plates 27 to rotate respectively, so that several groups of U-shaped plates 27 drive the rotating rod 25 to rotate inside the winding box 21, and the signal wires 11 wound inside the winding box 21 can be pulled out. After being pulled to the required length, the six groups of ECG detection probes 1 are placed one by one on specific positions of the patient's body, and then the electrocardiograph is operated. The six groups of ECG detection probes 1 placed on the body surface are used to capture the cardiac electrical signals and convert them into weak currents, which are then transmitted to the inside of the junction box through the six signal wires 11. With the cooperation of the 8-to-1 analog switch CD4051, the acceleration sensor and the switching controller inside the junction box, the signals are accurately transmitted to the ADC, and converted into digital signals at the ADC, and then transmitted to the electrocardiograph. The electrocardiograph will amplify the electrical signals and display them in a graphic. This graphic is usually displayed in the form of multiple waveforms. The doctor will judge whether the electrical activity of the heart is normal based on the characteristics of the waveform shape, interval, amplitude and duration on the electrocardiogram.

[0033] After the detection is completed, by rotating the handle 22, the handle 22 drives the rotating rod 25 to rotate, and the rotating rod 25 drives the plurality of fixed plates 26 to rotate inside the winding box 21. At the same time, the plurality of fixed plates 26 respectively drive the upper and lower U-shaped plates 27 to rotate, so that the plurality of U-shaped plates 27 rotate inside the winding box 21, and the six signal lines 11 can be wound up and wound into the winding box 21 without hindering the operation of the staff and affecting the operation speed of the staff, so that the detection speed can be obtained. To ensure that the six signal lines 11 are prevented from being entangled or knotted, pick up the fixing block 31, insert the limiting rod 35 at one end of the fixing block 31 into the limiting hole 33, and push the fixing block 31 to move. At the same time, the fixing block 31 will also drive the two groups of plug rods 34 fixed thereto to move, so that the two groups of plug rods 34 are respectively inserted into the two groups of round holes 36, and the limiting rod 35 will be completely inserted into the limiting hole 33, so that the turning handle 22 can be fixed, which can prevent the turning handle 22 from rotating when the signal line 11 is pulled.
