Abstract
The sleeve has an internal slide carrying the chalk and moved along it by turning, using an internal screw thread in the sleeve. The slide has a screw thread (4) screwing into the sleeve (1), in which there are a number of openings (6) to allow gripping and turning of the slide. These openings can extend over nearly the entire sleeve length, one behind the other, being in the form of windows. The rear end of the slide can have a sharp edge, and the outside of the sleeve can have grooves for gripping. The great advantage of the design is simplicity and consequent low production costs.
