The thermistor 23 can change the resistance according to the temperature. The upper end surface of the contact base 16 extends into the internal working chamber 19 and is fixedly provided with a power module 21.

[0027] Two connection ports 22 are fixedly disposed on the lower end surface of the power module 21 , and the connection ports 22 are fixedly connected to the upper end surface of the thermistor 23 .

[0030] An external fixing plate 17 is fixedly disposed on the outer circumferential surface of the contact base frame 16 , and an upper end surface of the external fixing plate 17 is fixedly connected to a lower end surface of the lifting outer plate 14 .

[0031] A buffer spring 15 is fixedly connected between the upper end surface of the lifting outer plate 14 and the middle part of the outer circumferential surface of the frame 11, and the buffer spring 15 can play a buffering role.

[0032] A handle 12 is fixedly disposed on the right end face of the frame 11 , and a control panel 13 is fixedly disposed on the front end face of the frame 11 . The control panel 13 can control the start and stop of all devices of the utility model and display the detected temperature.

[0033] Specific workflow:

[0034] When performing temperature detection, the control panel 13 can be used to start the power module 21 to start transmitting electrical energy and transmit it to the thermistor 23 through the connection port 22. After the loop is formed, the handle 12 can be held to contact the lower end surface of the contact base 16 with the object to be detected.

[0035] In order to prevent the thermistor 23 and the contact base 16 from being damaged due to excessive force during contact, when the contact base 16 receives external pressure, it will drive the external fixing plate 17 and the lifting outer plate 14 together with the thermistor 23, the connecting port 22, and the middle partition 24 to move upward. At this time, the buffer springs 15 on both sides can perform the function of vibration reduction and buffering, thereby protecting the contact base 16 and the thermistor 23 and preventing the contact base 16 and the thermistor 23 from being damaged. During detection, the thermistor 23 is affected by temperature changes and changes its resistance. At this time, the voltage detector 18 can detect the resistance change of the power module 21, thereby determining the current detected temperature value.
