Each of the pivoting elements is pivotable around a transversal axis that is perpendicular to the longitudinal axis. ## Claims ### Claim 1 An apparatus comprising: a mandrel having a longitudinal axis; and a plurality of pivoting elements spaced apart along a circumference of a cross-section of the mandrel, each of the plurality of pivoting elements pivotable around a transversal axis that is perpendicular to the longitudinal axis, wherein each of the plurality of pivoting elements comprises: a first arm that is pivotable toward or away from the mandrel around the transversal axis; and a second arm intersecting the first arm at an angle of less than 180 degrees so that the second arm is pivotable toward or away from the mandrel as the first arm pivots away from or toward the mandrel. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein each of the plurality of pivoting elements is biased to pivot the first arm away from the mandrel. ### Claim 3 (depends on 1) The apparatus of claim 1, further comprising a wedging apparatus to cause the second arm to pivot away from the mandrel and the first arm to pivot toward the mandrel. ### Claim 4 An apparatus comprising: a running tool comprising a mandrel having a longitudinal axis and further comprising a plurality of pivoting elements spaced apart along a circumference of a cross-section of the mandrel; a component comprising a hole into which the running tool is at least partly inserted, each of the plurality of pivoting elements to engage a depression formed in the hole such that the component is supported by the plurality of pivoting elements, wherein each of the plurality of pivoting elements comprises: a first arm that is pivotable toward or away from the mandrel around a transversal axis; and a second arm intersecting the first arm; and a wedging apparatus to cause the second arm to pivot away from the mandrel and the first arm to pivot toward the mandrel. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein each of the pivoting elements is biased to pivot the first arm away from the mandrel. ### Claim 6 (depends on 4) The apparatus of claim 4, wherein the first arm is pivoted toward the mandrel as the running tool is inserted into the opening. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the first arm comprises a distal end that tapers in a distal direction therefrom, and the component is supported by the distal end when the first arm is inserted into the hole and is pivoted away from the mandrel. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the depression is a groove extending along a perimeter inside the hole. ### Claim 9 (depends on 4) The apparatus of claim 4, wherein the transversal axis is perpendicular to the longitudinal axis. ### Claim 10 (depends on 4) The apparatus of claim 4, wherein an opening of the hole is a polygon shape, and each side of the polygon shape is engaged by one of the pivoting elements. ### Claim 11 An apparatus comprising: a running tool comprising a mandrel with a longitudinal axis and further comprising a plurality of pivoting elements spaced apart along a circumference of a cross-section of the mandrel; a component to be engaged by the pivoting elements; and a housing comprising a bore into which the component in engagement with the pivoting elements of the running tool is inserted, the housing further comprising fastening elements that are radially aligned with the pivoting elements and are extendable so as to disengage the pivoting elements from the component. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the component comprises apertures radially aligned with the pivoting elements, the fastening elements are radially aligned with the apertures so as to extend through the apertures and fasten the component with respect to the housing. ### Claim 13 (depends on 11) The apparatus of claim 11, wherein the component comprises a hole into which the running tool is to at least partly be inserted, each of the plurality of pivoting elements to engage a depression formed in the hole such that the component is supported by the plurality of pivoting elements. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein each of the plurality of pivoting elements comprises a transversal axis about which a first arm is pivotable toward or away from the mandrel, and each of the plurality of pivoting elements is biased to pivot the first arm away from the mandrel. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the first arm is pivoted toward the mandrel as the running tool is inserted into the depression to engage the component. ### Claim 16 (depends on 14) The apparatus of claim 14, wherein the first arm comprises a distal end that tapers in a distal direction therefrom, and the component is supported by the distal end when the first arm is pivoted away from the mandrel after being inserted into the hole. ### Claim 17 (depends on 14) The apparatus of claim 14, wherein the depression is a groove extending along a perimeter inside the hole. ### Claim 18 (depends on 14) The apparatus of claim 14, wherein the transversal axis is perpendicular to the longitudinal axis. ### Claim 19 (depends on 13) The apparatus of claim 13, wherein the opening is a polygon shape, and each side of the polygon shape is engaged by one of the pivoting elements.
