Beschreibung
Zusammenfassung:	The invention relates to a self-adaptive melting loss prevention airspeed head clamp. The airspeed head clamp comprises a sleeve, a telescopic sealing ring, a thermistor, a locking part and a currentlimiting switch, wherein the sealing ring is arranged between the sleeve and the airspeed head and is configured to be in contact with the airspeed head in an extending state and not in contact with the airspeed head in a retracting state, the thermistor is embedded in the sealing ring, the locking piece acts on the sealing ring, and the current limiting switch is connected to the thermistor and the locking piece; when the temperature of the sealing ring is lower than or equal to the temperature threshold, the resistance value of the thermistor does not exceed the critical value, the current limiting switch is closed, the locking part is locked, and therefore the sealing ring is in an extending state. When the temperature of the sealing ring is higher than a temperature threshold, the resistance value of the therm
