skill in the art that the finger supporting key 34 is longer than surrounding fingers this is due to the greater outside dimension that key 34 creates key 34 must be able to deflect sufficiently to fit through the orientation profiles a longer finger allows that deflection without exceeding the elastic limit of the material of the finger this avoids permanent deformation thereof the fingers 32 carry the collet profile 50 which is made up of several different diameters of material such as wider section 52 narrower section 54 and larger wider section 56 from fig2 and 3 one of ordinary skill in the art will appreciate that collet profile 50 is deflected inwardly until reaching a matchable profile 16 that is complementary and expands outwardly to engage therewith if a load is desired to be held a surface of collet profile 50 will be configured to engage reverse cut 86 fig5 provides a cross sectional view of fig4 for clarity referring to fig6 and 7 the key 34 of the illustrated embodiment is shown in fig6 downhole end 36 of key 34 is shown to be angled on two sides 38 and 40 these surfaces assist key 34 in moving along helical edge 14 by helping to avoid gouging of metal each of the angles 38 40 are in one.
