FIELD: transport. ^ SUBSTANCE: proposed device comprises tooth arranged in adapter and connecting element with sleeve made from elastic deformable material, and key. Said tooth and adapter have holes and zones to receive said sleeve and key. Note that said key is inserted into sleeve to extend therefrom. Note also that said key is fitted aligned with sleeve to displace therein, while sleeve is arranged in adapter part. Key has end part that makes key base, and key head on the body opposite part. Key head has part that makes bearing surface with shifted center. The latter enters appropriate surface made in the tooth first hole. Key head end can be turned by actuator element. Key base has anchoring appliance that enters in elastically deformable sleeve due to first tightening preset-force action. Key base end has conical part that thrusts against tooth second hole making second tightening action exceeding aforesaid one and created by key turn. Key turn governs is shift relative to its initial axis and allows its locking by anchorage on either tooth metal components or different bearing zones. ^ EFFECT: appropriate locking of tooth-adapter link, higher labor safety. ^ 16 cl, 21 dwg |
