This invention belongs to the field of medical testing equipment technology, specifically an intelligent anti-loosening chest breathing effort testing device with a magnetic quick-change probe. The proposed solution includes: a magnetic suction mechanism, one end of which is fitted with a sleeve tube. This mechanism enables quick magnetic attachment and disassembly of the probe to the device body, and forms an intelligent anti-loosening seal through the magnetic attraction and elastic structure, preventing the probe from falling off and leakage of the patient's exhaled air during testing; and a testing mechanism, with both ends fixedly mounted on the other ends of the two magnetic suction mechanisms.
