Torque lever: This transmits the bolt torque to the transfer levers and serves as one part of the reduction system.

This has the sturdiest construction and connection to the body.

Transfer levers: These transfer the force from the torque lever to the release pawl. Each lever reduces the force transmitted.

Return spring: Returns the second transfer lever to its rest position and resets the pawl after each torque application.

Release pawl: This is tilted upwards when the correct torque is reached. When the torque is removed, the second transfer lever clicks back and pushes the pawl back to its original location.

When the torque is met, the spring force on the pawl is very close to equal to the force applied by the second transfer lever. Making calculation of spring force quite easy.

When the pawl is in the torque met position the spring force is barely keeping it open, meaning that there is a very small perpendicular distance between spring force and pivot. Making it easy for the return spring of the second transfer lever to overcome and return the pawl back to its rest position.
