[0037] After the electrocardiogram detection instrument is fixed, the cleaning mechanism 11 can be controlled to clean the smear cotton 6 during use, and then the motor 1001 can be controlled to rotate. When the motor 1001 rotates, it will drive the transmission gear 2 1003 to rotate through the transmission gear 1002. At this time, when the transmission gear rotates, the arc groove 14 above it will drive the splints 1004 to move away from each other through the transmission rods 1005 around it. At this time, the personnel can take out the smear cotton 6 through the auxiliary seat 8. Before this, the personnel can pour the conductive liquid into the inside of the liquid storage cup 7. At this time, the personnel can soak the smear cotton 6 in the liquid storage cup 7, and then apply it on the patient's skin. The auxiliary seat 8 can be fixed and limited by the fixing mechanism 10, and it can be stored after use to prevent the smear cotton 6 from being lost.

[0039] After the smear cotton 6 is used up, the smear cotton 6 can be inserted back into the groove 5. At this time, the personnel can control the motor 2 1101 to rotate. The motor 2 1101 will drive the push plate 1103 to move through the transmission screw 1102. At the same time, the push plate 1103 will drive the cleaning plate 1108 to move synchronously through the push rod 1104. At this time, the cleaning plate 1108 will push out the conductive liquid on the smear cotton 6 by squeezing. During the movement of the cleaning plate 1108, the water pump 1106 can be controlled to extract the alcohol inside the water tank 1105, so as to rinse the surface of the smear cotton 6 through the cleaning nozzle 1107. During the cleaning process of the cleaning plate 1108 cleaning the smear cotton 6, its bottom end will also push the cleaned liquid into the collection box 1109 through the cleaning tank, so as to ensure the cleanliness of the inside of the cleaning tank and prevent bacteria from growing.

[0040] like Figure 3 , 7-8, the auxiliary mechanism 12 includes a handwheel 1201, a transmission screw rod 1202, an auxiliary plate 1203, an anti-skid pad 1204, a slide rail 1205 and a slider 1206, the bottom end of the auxiliary plate 1203 is threadedly connected to the outer wall of the transmission screw rod 1202, the anti-skid pad 1204 is fixedly connected to the inner wall of the auxiliary plate 1203, both sides of the bottom end of the auxiliary plate 1203 are fixedly connected to the top of the slider 1206, and the slider 1206 is slidably connected to the top of the slide rail 1205, one end of the transmission screw rod 1202 passes through one side of the bottom end of the support frame 9 and is fixedly connected to the axis of the handwheel 1201, and the other end of the transmission screw rod 1202 is rotatably connected to the bottom end of the support frame 9, a group of front-to-back symmetrical mounting grooves are opened at the top of the support frame 9, and the slide rail 1205 is fixedly connected to the inside of the mounting groove, the auxiliary plate 1203 is movably connected to the top of the support frame 9, and the slider 1206 is slidably connected to the inside of the mounting groove.

[0041] First, after placing the ECG detector on the support frame 9, you can manually turn the handwheel 1201. When the handwheel 1201 is rotated, it will drive the auxiliary plate 1203 above to move toward the ECG detector through the transmission screw 1202, thereby fixing the instrument. At the same time, the slider 1206 and the slide rail 1205 can reduce friction, thereby increasing the service life.

At the same time, installing the ECG detector on the support frame 9 can also make it more convenient for personnel to transfer it, thereby improving work efficiency.

[0042] Here's how it works.

[0043] When in use, first, after placing the electrocardiograph on the support frame 9, the hand wheel 1201 can be turned. When the hand wheel 1201 is turned, the auxiliary plate 1203 above will be driven to move toward the electrocardiograph through the transmission screw 1202.

After the fixing is completed, the cleaning mechanism 11 can be controlled to clean the smear cotton 6 during use, and then the motor 1001 can be controlled to rotate. When the motor 1001 rotates, it will drive the transmission gear 2 1003 to rotate through the transmission gear 1002. At this time, when the transmission gear rotates, the arc groove 14 above it will drive the clamping plates 1004 to move away from each other through the transmission rods 1005 around it. At this time, the personnel can take out the smear cotton 6 through the auxiliary seat 8. Before that, the personnel can pour the conductive liquid into the inside of the liquid storage cup 7. At this time, the personnel can take out the smear cotton 6. 6 is soaked in the liquid storage cup 7, and then it can be applied to the patient's skin. The auxiliary seat 8 can be fixed and limited by the fixing mechanism 10, and it can be stored after use to prevent the smear cotton 6 from being lost. At the same time, it can also effectively reduce the growth of bacteria on the smear cotton 6, thereby ensuring the safety of the patient. After the smear cotton 6 is used, the smear cotton 6 can be inserted back into the groove 5. At this time, the personnel can control the motor 2 1101 to rotate, and the motor 2 1101 will drive the push plate 1103 to move through the transmission screw 1102.
