Second portion 3114 passes through positioning ring 374 of second wristband body 371, positioning member 375 is inserted into first wristband through hole 313 to position first wristband body 311, and second portion 3114 is fixed by fixing ring 376 to a side of second wristband body 371 away from the skin of the user, second portion 3114 is away from the skin of the user, cold end 322 of thermocouple unit is disposed in second portion 3114, cold end 322 of thermocouple unit is away from the skin of the user, and cold end 322 of thermocouple unit is prevented from being affected by the temperature of the skin of the user, wherein cold end 322 of thermocouple unit may be disposed in second portion 3114 or on the surface of second portion 3114.

It is understood that in other embodiments, the first portion 3112 can be the entire first watchband body 311, the second portion 3114 can be a portion independent of the first watchband body 311, and the second portion 3114 can be connected to the first watchband body 311 and oriented away from the skin of the user.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
