A clamping mechanism comprises a nut 100, a clamp plate 200, a bolt 300 and a block 47. The nut 100 has an axial bore with a screw thread 114 formed on an inner surface of the bore. The bolt 300 has a pair of arms 332a, 332b and a cross piece 336 joining the arms 332a, 332b together. The arms 332a, 332b have a screw thread 334 formed on an outer surface of the arms 332a, 332b corresponding to the screw thread 114 of the nut 100. The clamp plate 200 has an elongate body 225 narrower than the separation between the arms 332a, 332b so as to fit between the arms 332a, 332b. The block 47 can be engaged with the nut 100 for movement therewith, the block 47 extending between the arms 332a, 332b of the bolt 300. The block 300 opposes flexure of the arms 332a, 332b towards each other as the nut 100 is screwed onto the bolt 300. |
