The jig comprises an operation table and a frame body fixedly installed at the top of the operation table, a double-thread rod is arranged in the frame body in a rotating mode, according to the size of a PCB body, a first motor is started to drive the double-thread rod to rotate, two sliding bases are adjusted to move, and then an adjusting frame is controlled to move. Two air cylinders are started to push a bottom adjusting frame to descend, meanwhile, a second motor is started to drive a gear to rotate, the gear drives a toothed bar to move, and the toothed bar drives a lower pressing frame at the bottom to press rubber columns on the four corners of the PCB body; the height of the four rubber columns is larger than the height of the PCB body, so that the PCB body is pressed and held to make contact with the rubber columns firstly, the influence of scratching and scratching on the PCB body in the production process is avoided, meanwhile, vibration generated between the PCB body and external equipment can be
