The invention discloses a handheld vehicle polisher, and belongs to the field of handheld electric tools. The technical purpose is to solve the problems that nearby regions of a corner surface and anobstacle of a vehicle are not easily polished, the efficiency is low, and the polishing effect is poor. The handheld spot welding clamp comprises a shell, a motor arranged in the shell and a polishingassembly which is arranged at the bottom of the shell and is driven by the motor, the polishing assembly comprises a turntable and at least two polishing wheels which are uniformly distributed in thecircumferential direction of the turntable, the turntable is driven to rotate through the motor, the polishing wheels can freely rotate relative to the turntable along the axis of the wheels, an edgeobstacle avoidance area is formed between any two polishing wheels of the polishing wheels, all polishing wheels jointly form a center obstacle avoidance area in the center area of the turntable, andthe edge obstacle avoidance area is communicated with the center obstacle avoidance area. Compared with an existing handheld vehicle polisher, the nearby regions of the corner surface and the obstacle of the vehicle can be well subjected to polishing work, the operation difficulty is low, the polishing efficiency is high, and the polishing effect is good.
