The utility model discloses a double-strong-magnet adjustable attracting-type fixing device rack which includes two magnetic plates, bolts and a support rod. Center holes are arranged in the two magnetic plates. The bolts are arranged in the center holes of the magnetic plates in a sleeved manner. Studs of the bolts on the two magnetic plates are at the same side of the two magnetic plates. The support rod is connected with the studs of the two bolts. A threaded rod used for assembly with a threaded hole in a temperature measurement probe is arranged on the support rod. During use, the two magnetic plates are attracted to the inner side wall of a door of a switch cabinet. The temperature measurement probe is installed on the threaded rod so that it can be realized that the temperature measurement probe is fixed firmly and not likely to fall off; and the temperature measurement probe is capable of changing installation position and angle with adjustment of the length of the support rod and rotation of a rod body of the support rod so that more accurate temperature measurement data can be realized.
