L'appareil limiteur de force (3) de type force magnétique comprend deux parties de traction (3.1, 3.2) qui sont attirées au moyen d'une force magnétique de façon à former un ensemble de raccordement à traction, une force de traction étant exercée sur ledit ensemble de raccordement à traction; et lorsque la force de traction atteint la force d'attraction magnétique, les parties de traction (3.1, 3.2) glissent pour libérer une force de traction et jouent finalement un rôle de protection. Du fait qu'il n'y a pas besoin d'élément électronique, l'appareil limiteur de force (3) de type force magnétique n'est pas hors contrôle et peut garantir la sécurité. De plus, l'invention concerne un lit de traction de corps vertébral utilisant l'appareil limiteur de force (3) de type force magnétique. Le lit de traction de corps vertébral comprend un corps (1), un appareil de commande électrique (2) et un appareil à anneau de traction (4). L'appareil limiteur de force (3) de type force magnétique est raccordé en série à l'appareil à anneau de traction (4), la force d'attraction magnétique de l'appareil limiteur de force (3) de type force magnétique est une force de traction sûre, et lorsque la force de traction atteint un niveau de sécurité, l'ensemble de raccordement est séparé et libère la force de traction et, par conséquent, la sécurité du corps humain est garantie.
