Torque wrench and friction processing equipment

The invention provides a torque wrench and friction processing equipment. The torque wrench is used for twisting a friction roller to make the friction roller rotate around the own axis, a fixing groove is formed in the end face of the friction roller, the torque wrench comprises a handheld part and a clamping part connected with the handheld part, and the clamping part can be clamped with the fixing groove so that relative position of the clamping part to the friction roller can be fixed. The torque wrench can twist the friction roller to make the friction roller rotate, and therefore damage and contamination to the friction roller due to direct twisting through hands are prevented.
