Yellow collar and gray block have continuous V-thread.
When wear takes place in the pink lead screw, the collar always maintains pressure on threads thanks to the black circular spring that applies torque to the collar.
Contact occurs between the left side of the screw and the gray block and between the right side of the screw and the yellow block.
The video shows how the yellow collar and pink screw move under the influence of the spring.
The spring torque must be larger than the working torque applied to the the screw.
