  • the abutment projections are in the form of spigots as shown in Figures 1 -12, but could be any other suitable shape as required such as for example hooks.
  • the locking member 13 comprises a generally cylindrical body 63 which is inserted into the locking recess through the top surfaces of the point and the adaptor.

  • the locking member 13 is therefore submerged below the top surface of the point 12 once it is inserted into the locking recess and remains submerged when locking the point and the adaptor in their assembled condition. This protects the locking member from wear.

  • the resiliently compressible member may also be a spring or other suitable member as required. As the locking member 13 is moved into its locking condition, the compressible member is compressed. The resilience of the compressible member provides take-up for the lock member 13 as the components of the excavation tooth assembly wear during use. It is to be understood that the resiliently compressible member may instead form part of the locking structure rather than the lock member.
