A socket base comprising a support ring having a support ring frame and a base plate having a base bottom, wherein the support ring comprises latching pins which each have a latching pin end as well as at least one first and/or second latching resistance (3, 4), wherein the base plate comprises guide receptacles (102, 112) for said latching pins, wherein the guide receptacles (102, 112) each have at least one first and/or at least one second latching recess (103, 104) for the first and/or second latching resistance (3, 4), in particular at least first and second latching recesses (103, 104) for the first and second latching resistance (3, 4), wherein the distance between the support ring frame and the base bottom can be adjusted with said latching pins, characterized in that the guide receptacles each have a first receptacle side and an opposite second receptacle side (117, 118), wherein the at least one first latching recess, in particular two first latching recesses, is/are present in the first receptacle side and the at least one second latching recess, in particular two second latching recesses, is/are present in the second receptacle side (117, 118), wherein the at least one first latching resistance, in particular all of the first latching resistances, is/are inclined in the direction of the corresponding first receptacle side and the at least one second latching resistance, in particular all of the second latching resistances, is/are inclined in the direction of the corresponding second receptacle side (117, 118), and wherein the socket base is adapted and arranged to be moved from a first state into a second state, wherein the support ring frame has, in the first state, a first adjusting distance from the base bottom and, in the second state, a second adjusting distance from the base bottom, wherein the second adjusting distance is larger or smaller than the first adjusting distance. wherein the support ring comprises latching pins which each have a latching pin end as well as at least one first and/or second latching resistance (3, 4), wherein the base plate comprises guide receptacles (102, 112) for said latching pins, wherein the guide receptacles (102, 112) each have at least one first and/or at least one second latching recess (103, 104) for the first and/or second latching resistance (3, 4), in particular at least first and second latching recesses (103, 104) for the first and second latching resistance (3, 4), wherein the distance between the support ring frame and the base bottom can be adjusted with said latching pins, characterized in that the guide receptacles each have a first receptacle side and an opposite second receptacle side (117, 118), wherein the at least one first latching recess, in particular two first latching recesses, is/are present in the first receptacle side and the at least one second latching recess, in particular two second latching recesses, is/are present in the second receptacle side (117, 118), wherein the at least one first latching resistance, in particular all of the first latching resistances, is/are inclined in the direction of the corresponding first receptacle side and the at least one second latching resistance, in particular all of the second latching resistances, is/are inclined in the direction of the corresponding second receptacle side (117, 118), and wherein the socket base is adapted and arranged to be moved from a first state into a second state, wherein the support ring frame has, in the first state, a first adjusting distance from the base bottom and, in the second state, a second adjusting distance from the base bottom, wherein the second adjusting distance is larger or smaller than the first adjusting distance.
