The invention discloses a tool component for cutting a touch screen protection film. The tool component comprises a cutter, a first guide column, a second guide column, an electromagnet, a tool apron, a magnetic block, an elastic ejector and a knob. The first guide column and the second guide column are parallelly arranged at intervals, the tool apron comprises a first guide portion, a second guide portion and a mounting portion, the first guide portion and the second guide portion penetrate the first guide column and the second guide column respectively, the mounting portion is provided with a through hole, the cutter, the magnetic block, the elastic ejector and the knob are arranged in the through hole, the magnetic block attracts the cutter so that a cutting edge of the cutter downwardly extends out of the through hole, the elastic ejector is elastically ejected between the magnetic block and the knob, the knob is connected with the mounting portion in a threaded manner, the electromagnet generates magnetic force in electrification and attracts the tool apron to move downwards, and the cutting edge of the cutter is pressed on the touch screen protection film. The pressure of the cutter is controlled by adjusting current and can be accurately controlled, and cutting effects are ensured.
