The present invention relates to the technical fields of automobile maintenance and device calibration, and discloses a calibration device, the calibration device comprising: a laser assembly; a calibration bracket, comprising a loading platform, the loading platform being used for supporting the laser assembly; and a magnetic element, mounted on one of the laser assembly and the loading platform, and being used for attracting the other of the laser assembly and the loading platform. By means of arranging the magnetic element on one of the loading platform and the laser assembly, the magnetic element can attract the other of the loading platform and the laser assembly, so that when the laser assembly needs to be mounted on the loading platform, the laser assembly only needs to approach the loading platform and the laser assembly will be attracted to the loading platform due to the magnetic force provided by the magnetic element and, when the laser assembly needs to detach from the loading platform, the laser assembly only needs to be subjected to force to overcome the magnetic force provided by the magnetic element in order to separate the laser assembly from the loading platform, making detachment of the laser assembly and the calibration bracket convenient.
