The utility model discloses a power pen used for performance detection of liquid crystal display products. The power pen comprises an insulation penholder, a through hole, and two sliding grooves, and a first fixing block capable of sliding along the sliding grooves. The first fixing block is provided with a first conductive column, and a second fixing block is fixedly disposed in the pen holder, and is provided with a second conductive column. A screw rod is provided, and one end of the screw rod is fixedly disposed in the penholder, and the other end of the screw rod is provided with a nut sleeve pipe. One end of the nut sleeve pipe is disposed on the outer side of the side wall of the penholder, and the other end of the nut sleeve pipe abuts against the outer side wall of the first fixing block. The screw rod is provided with a pressure spring in a sleeved manner, and two ends of the pressure spring abuts against the first fixing block and the second fixing block respectively. The power pen provided by the utility model can be used to solve the problems of the conventional display screen FPC electrical performance test that the users are required to hold two power lines, which can be contacted with the positive pole and the negative pole of the FPC, to satisfy the test requirements, the operation is not convenient, the production efficiency is low, and the use is not safe. The power pen provided by the utility model can be widely used for the liquid crystal display product performance detection field.
