The invention discloses a tool clamp device for electronic element machining and maintenance. The tool clamp device comprises a base, a clamping mechanism is installed on the base, a driving mechanismis arranged on the base and located on one side of the clamping mechanism, and a control mechanism is arranged on the base and located on one side of the clamping mechanism. The tool clamp device forelectronic element machining and maintenance has the beneficial effects that the structure is reasonable, the use is convenient, clamping can be carried out according to the size of a circuit board,the circuit board is extremely precise, the circuit board can be effectively protected, so that the circuit board can be machined conveniently, and then the problems that the circuit board needs to beclamped and fixed so as to facilitate the operation when the circuit board is machined, due to the fact that the circuit board is precise and the strength is poor, the clamping force cannot be too large during clamping, then the circuit board can be prevented from being damaged, but a common clamp is large in size and not suitable for clamping the circuit board are solved.
