Simple and convenient electrocardio lead plaster applied to dynamic electrocardio recorder

The invention discloses a simple and convenient electrocardio lead paste applied to a dynamic electrocardio recorder, and belongs to the technical field of medical equipment.The electrocardio lead paste covers the chest of a human body, so that by means of heat generated during long-time covering, a memory alloy spring is prompted to recover to the high-temperature phase state, a piston plate is pushed to move downwards until the piston plate moves to the joint with a lower limiting ring, a first air hole and a second air hole are the same, thereby promoting the discharge of hot air generated between the electrocardio lead paste and a human body, and a rotating block can be promoted to rotate by means of the blowing of swinging air slurry while the air flows, a magnetic end ball can be driven to move upwards and downwards by means of the repulsion or attraction of the rotating block to the magnetic end ball, on the one hand, the effect of absorbing sweat of a built-in magnet block can be improved, on the othe
