[0002] Thermohygrometers for motor vehicle inspections are usually specialized instruments used to measure the temperature and humidity conditions inside a vehicle. These thermohygrometers usually have high-precision sensors that can accurately measure the temperature and humidity inside the vehicle and display the data on the instrument's screen. These thermohygrometers also usually have data logging and storage functions to help inspectors perform vehicle inspections and analysis. During vehicle repair and maintenance, these thermohygrometers can also help technicians better understand the environmental conditions inside the vehicle so that they can better perform maintenance and repairs.

[0003] During use, the thermometer and hygrometer for motor vehicle inspection in the prior art is simply placed on the center console of the motor vehicle compartment. However, when the motor vehicle is moving, the thermometer and hygrometer body lacks a structure that can be fixed inside the motor vehicle, resulting in poor stability during the motor vehicle driving test, which in turn makes it easy for the motor vehicle to fall and be damaged during braking or sudden starting. Secondly, the thermometer and hygrometer body will be equipped with a charger that matches the vehicle, but the charger and the thermometer and hygrometer body are electrically connected through a long power cord, and there is a lack of a structure that can adjust and store the power cord for use. The length, resulting in the power cord being too long and prone to damage. For this reason, we have designed a thermometer and hygrometer for motor vehicle inspection to solve the above problems.
