Thermal bulb fixing device and compressor

The utility model discloses a thermal bulb fixing device and a compressor, and aims to solve the problem that the temperature sensing efficiency is reduced due to the fact that the conventional thermal bulb fixing structure fixes a thermal bulb and the temperature sensing surface of the thermal bulb is in linear contact with a surface to be measured. The utility model relates to a thermal bulb fixing device, which comprises an installation part, a fixing part and a fixing part, wherein the installation part is provided with a first groove which is attached to a temperature sensing surface on a thermal bulb and limits the axial movement of the thermal bulb; the elastic piece is provided with a fixed part and a free part, the fixed part is fixedly installed on the installation piece, the free part and the first groove are oppositely arranged, and the free part tightly presses the temperature sensing bulb in the first groove through the elastic force of the free part. According to the utility model, the temperat
