' IX DESCRIPTION OF THE INVENTION: 1. Technical Field of the Invention The present invention relates to a temperature measuring device, and more particularly to a thermocouple temperature measuring device. [Prior Art] Thermocouple is one of the most commonly used temperature detecting components in the industry. Its advantages include: high measurement accuracy, wide temperature range (-200QC-2000QC), • point-by-point measurement and simple structure. The basic principle of thermocouple temperature measurement is based on the Seeback effect, that is, the conductors or semiconductors of two different components are connected at both ends into a loop. If the temperature of the two terminals is different, the physical phenomenon of thermal current is generated in the loop. A conventional thermocouple usually consists of two different wires composed of two hot electrodes, such as a combination of copper or iron, and a protective sleeve. One end of the two hot electrodes is welded to each other to form a measuring end of the thermocouple (also called a working end). ) and insert it into the temperature medium to be tested or in contact with the object to be tested; and the other end of the thermocouple (also known as the reference or free end) is connected to the display instrument. If there is a temperature difference between the measuring end and the free end of the thermocouple, the display meter will indicate the thermoelectromotive force generated by the thermocouple. In addition, in order to ensure reliable and stable operation of the thermocouple, the structure of the conventional thermocouple includes the following requirements: the welding of the two hot electrodes constituting the thermocouple must be firm; the two hot electrodes should be insulated from each other to prevent short circuit; The casing should ensure that the hot electrode is sufficiently isolated from the harmful medium; the thermal resistance of the contact between the thermocouple and the object to be tested is small. However, the traditional thermocouple is often used because the surface of the thermocouple and the object to be tested is solid, and the diameter of the thermocouple itself is 1275783, which is easy to cause the temperature difference between the contact surface and the thermal resistance of the interface, so that the temperature and the actual amount are measured. Measuring the temperature produces an error, which causes great inconvenience in measurement. In view of this, it is necessary to provide a thermocouple temperature measuring device with high accuracy and reliability. SUMMARY OF THE INVENTION Hereinafter, a thermocouple temperature measuring device having high accuracy and reliability will be described by way of embodiments. In order to achieve the above, a thermocouple temperature measuring device is provided, comprising: a thermocouple comprising two wires, one ends of which are connected to each other to form a measuring end of a thermocouple, and the other ends are connected to each other to form a free end of the thermocouple. a holding device, the holding device includes a force measuring device and a holding leg disposed on the force measuring device, the holding leg is configured to hold the measuring end of the thermocouple and provide a predetermined contact force of the measuring end of the thermocouple It is in contact with the surface of the object to be tested; and a thermostat is connected to the free end of the thermocouple. Compared with the prior art, the thermocouple temperature measuring device provided by the embodiment of the invention has the following advantages: First, the contact force between the thermocouple and the object to be tested can be accurately controlled by using the holding device, so that the contact thermal resistance is stabilized, and the measurement is ensured. It is stable and reliable. Secondly, the holding end of the holding device holds the measuring end of the thermocouple, and the temperature can be measured in a small space, without worrying about the problem that the thermocouple cannot be fixed. Third, the use of the holding device can effectively reduce Due to the measurement error caused by the thermocouple bending or insufficient contact with the object to be tested when the thermocouple is fixed, the accuracy of the thermocouple temperature measurement can be improved. 1275783 [Embodiment] Hereinafter, the technical solution will be further described in detail with reference to the accompanying drawings.
