When the connecting plug moves, it will enter the interface under the guidance of the trapezoidal block to prevent deviation during connection, which will affect the operation speed and delay the rescue time. At the same time, when the baffle moves away from the hollow frame, it will drive the short plate to move away from the hollow frame. When the short plate moves away from the hollow frame, it will break away from the contact with the limit plate, causing the limit plate to lose its squeeze. The sliding block will protect the connecting plug by resetting it, preventing the connecting plug from being pulled during use, causing looseness between the connecting plug and the instrument body, resulting in a sudden short circuit during use, affecting the rescue efficiency. (2) The invention, by rotating one end of the rotating support plate downward, drives the other end of the rotating support plate to rotate upward, and the other end of the rotating support plate rotating upward will lift the bottom of the rotating wheel to prevent the connecting line from being too loose when wound, causing the connecting line to get stuck when winding, affecting normal use. The roller rotating upward will push the connecting line to fit together with the rotating wheel to prevent the connecting line from being too loose when winding, causing the connecting line to get tangled during winding, affecting normal winding and unwinding, causing the connecting line to get stuck during rescue, affecting rescue efficiency. (3) In this invention, the lubricating oil inside the hollow tube flows downward, and the lubricating oil enters the arc-shaped sponge through the hollow tube, and is smeared on the rotating part of the rotating wheel through the arc-shaped sponge. The rotating wheel is lubricated by the lubricating oil to prevent the rotating wheel from being difficult to rotate due to long-term lack of maintenance. When in use, it cannot rotate normally to release the line, affecting the rescue time. At the same time, the connecting push rod moves in the direction close to the trapezoidal plate, which squeezes the trapezoidal plate to move downward. The downward movement of the trapezoidal plate drives the sealing plate to seal the hollow tube. At the same time, the downward movement of the sealing plate drives the sealing circular plate to move downward. Through quantitative lubrication, excessive lubrication is prevented to cause waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

By placing the instrument body 4 inside the protective box 1, the instrument body 4 is convenient to carry, so that the instrument body 4 is easy to use, and cardiac defibrillation can be performed in time, which improves the use effect of the instrument body 4. An alarm is arranged inside the instrument body 4, and the alarm is electrically connected to the instrument body 4. When an obvious heart rhythm occurs, In case of abnormality, an alarm can be sounded or the alarm can be linked to the hospital platform to remind the patient to stop rehabilitation activities.
