Dipper tip retaining pin |
摘要 |
An adapter-tip retainer pin has a wedge member and a lock member joined by a first pair of walls on a resilient member. The resilient member includes a central cavity and a second pair of walls which are curved inwardly toward the cavity such that the second pair of walls collapse inwardly when the retainer pin is compressed during insertion or removal from an adapter-tip assembly.
