After the temperature measurement is completed, the rotating knob can be turned in the opposite direction to drive the gear plate to rotate in the opposite direction. At this time, the adjustment rod moves upward inside the movable groove and moves to the positioning block inserted into the positioning seat to stop. The positioning seat and the positioning block are connected and positioned from the external position of the outer cylinder by using the bayonet pin. At this time, the probe body is retracted into the inside of the movable groove, and then the connection and installation of the protective cover are completed by using the external thread end. Therefore, the protective cover is used to complete the secondary protection, thereby better improving the overall hidden protection capability of the probe during the working process;

[0016] (3) The storage box is installed on the side of the food thermometer body, and a positioning groove is opened at the bottom of the storage box. The small brush is passed through a limit ring so that the bottom of the small brush reaches the position of the positioning groove and is positioned. Then, the top is closed by connecting the storage box with a threaded block. When necessary, the threaded block can be disassembled, and then the small brush can be taken out and used to clean the dust on the end surface of the display screen, thereby improving the overall convenience during work.
