Then, the concave block 402 is inserted into the silicone watchband 3. After the concave block 402 enters the silicone watchband 3, the bolt head 901 can be rotated forward to move the screw rod 902 toward the silicone watchband 3, and the engaging block 903 slides into the engaging groove 904 provided in the concave block 402, thereby completing the installation of the silicone watchband 3; Then, the skin-fitting pad 601 at the bottom of the liquid crystal dial 1 is attached to the wrist and worn. When the multiple silicone straps 3 are rotated, the silicone straps 3 will drive the concave blocks 402 to move accordingly, and when the concave blocks 402 move, the connecting rods 403 will move together, so that when the connecting rods 403 move, the corrugated tubes 404 and the tension springs 405 are stretched, and the elastic force provided by the corrugated tubes 404 and the tension springs 405 can prevent the connection of the silicone straps 3 from breaking or loosening. When the skin-contacting pad 601 contacts the wrist during wearing, it will shrink accordingly, and the skin-contacting pad 601 will drive the connecting rod 602 to move together, and when the connecting rod 602 moves, it will drive the cross plate 603 to move together, so that the two rotating rods 604 rotate towards each other, and when the two rotating rods 604 rotate towards each other, the two rotating rods 604 control the two linkage blocks 605 to move towards each other, so that the linkage blocks 605 move along the guide rod 607 and stretch the spring 1 608, and by stretching the spring 1 608, the spring 1 608 provides a force, so that the skin-contacting pad 601 can always fit the wrist of the user, thereby achieving a certain comfort.

The wearable physical condition monitoring device according to claim 2, characterized in that: The spring one (608) is sleeved on the outer circumference of the guide rod (607), and the guide rod (607) and the side of the spring one (608) away from the movable block (606) are fixedly connected inside the liquid crystal dial (1).

9. The wearable physical condition monitoring device according to claim 4, characterized in that: The engaging block (903) is slidably connected inside the engaging groove (904).

10. A method for using a wearable body condition monitoring device, according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, open the two partitions (701) of the mounting block (5), rotate the partition (701), and pull it at the same time to drive the insertion rod (703) to move, the movement of the insertion rod (703) will drive the limit plate (704), squeeze the slot (705), put the electrocardiogram signal sensor (10) into the mounting block (5), loosen the partition (701), and use the reset thrust of the second spring (706) to push the limit plate (704) and the insertion rod (703) to fix the electrocardiogram signal sensor (10); S2, according to the wrist size of the wearer, select and install an appropriate amount of silicone watch strap (3), reverse the bolt head (901), move the screw rod (902) in the silicone watch strap (3), drive the fitting block (903) to slide into the fitting groove (904) of the concave block (402), and after the installation is completed, rotate the bolt head (901) forward to fix the silicone watch strap (3); S3, fit the skin-fitting pad (601) at the bottom of the liquid crystal dial (1) to the wrist. During the wearing process, the silicone strap (3) will drive the concave block (402) and the connecting rod (403) to move, and the corrugated tube (404) and the tension spring (405) provide elasticity to prevent the connection from breaking or loosening. When worn, the skin-fitting pad (601) automatically adjusts the fit. The skin-fitting pad (601) drives the connecting rod (602), the horizontal plate (603), and the rotating rod (604) to move. The rotating rod (604) pulls the linkage block (605) to move, and the guide rod (607) slides in coordination and stretches the spring 1 (608) to ensure that the skin-fitting pad (601) fits the wrist. If manual adjustment is required, the adjustment knob (12) on the liquid crystal dial (1) can be rotated to switch the display interface or adjust the sensitivity; S4, use the charging port (13) (Type-C) to charge the device, ensure that the device is connected to the data center to upload real-time monitored health data, view pulse signal and electrocardiogram signal health data through the LCD dial (1), and cooperate with the analysis function of the mobile application or the data center to perform personalized health management.
