The invention discloses a torque wrench tool box. The tool box comprises a box body and a box cover; the box body is internally provided with a space capable of allowing a wrench body to be placed stably, a proximity sensor for sensing the wrench body and a plurality kinds of common accessory storage lattices; and a circuit board assembly capable of recording relevant information of the torque wrench is installed on the inner wall of the box cover and comprises a driving chip, a single-chip microcomputer, a USB interface, an LED liquid crystal display panel and a buzzer which are electricallyconnected. According to the tool box, the proximity sensor can sense whether the wrench enters the box or not, the output signal of the sensor is connected to the digital signal interface of the single-chip microcomputer, the single-chip microcomputer calculates and processes the actual service time and frequency of the wrench, the state that the torque wrench reaches the verification period can be displayed and prompted on the liquid crystal display panel of the tool box, and the buzzing alarm is carried out; the common accessory storage lattices are simple and practical so that matching accessories can be convenient to store; and the structure of the torque wrench tool box is reasonable, and the relevant information of the torque wrench can be recorded so that the wrench can be conveniently managed.
