Abstract: A tunnel operation robot includes a robot body, a walking module, a fixed wing module and a plurality of rotatable wing modules. Both sides of the robot body are provided with cantilever parts, which are collinearly arranged. The walking module is arranged on the robot body. The fixed wing module includes a fixed fan, is fixedly arranged on the robot body, and is configured to provide a pressure for the walking module to be attached to and pressed against the tunnel wall surface. The plurality of rotatable wing modules are respectively arranged on the cantilever parts on both sides of the robot body, and include a rotatable rotating fan and a wind direction adjustment driver. Each rotating fan has a rotation axis parallel to the cantilever parts and an air outlet direction perpendicular to the cantilever parts, and the wind direction adjustment driver is connected to the rotating fan.

Abstract: The disclosure relates to a motor vehicle lock with a lock mechanism and with a lock housing to receive the lock mechanism, wherein the lock mechanism comprises at least one activating lever which can swivel about a geometrical lever axis, wherein a bearing sleeve element is provided, on which the activating lever is radially mounted, wherein the activating lever is mounted on the bearing sleeve element axially at both sides and for this it is coupled to the bearing sleeve element by a bayonet fitting and in the process of installing the motor vehicle lock the activating lever and the bearing sleeve element can be premounted to form a separate unit by creating the bayonet fitting.
