Patent ID: 7303333

Claim:
A thermometer comprising: a metal tip member with a thermal contact surface; a flexible probe body, comprising an outer narrower portion surrounding an inner narrower space extending into the metal tip member and an outer wider portion surrounding an inner wider space disposed behind the metal tip member and communicated with the inner narrower space, secured to the metal tip member by a hook structure; a thermal sensor, mounted on the inside of the thermal contact surface of the metal tip member, for sensing the temperature of the thermal contact surface and producing a temperature signal; and a set of lead wires, coupled to the thermal sensor for transmission of the temperature signal; wherein the hook structure comprises: a first hook, disposed behind the metal tip member and embedded in the inner wider space against a rear end of the outer narrower portion of the flexible probe body; a second hook, embedded in the metal tip member against a front end of the outer narrower portion of the flexible probe body; and a hook connection, embedded in the inner narrower space to connect the first hook and the second hook, wherein the first hook, the second hook and the hook connection are formed as one piece passing through the metal tip member, the inner narrower space and the inner wider space.
