AI Technical Summary
Technical Problem
The tip of existing crayons is easily exposed, which makes it easy to mis-paint during use, and the tip cannot be retracted, affecting the effect of use.
Method used
It adopts a spiral guide groove and guide groove structure, and realizes the retractable storage of crayon tip through the relative rotation of the outer tube and the inner tube. The cooperation of slider and guide block ensures that the tip is stored when not in use, avoiding accidental smudging.
Benefits of technology
It achieves stable expansion and contraction of the crayon stick core, avoids accidental application, and improves the effect and stability of use.

Abstract
The utility model discloses a double-end crayon for adults, and aims to provide the double-end crayon for adults, which has the advantages that the nib can be stored, mistaken painting is avoided, and the use effect is improved. Comprising two outer pipes, and spiral guide rail grooves are formed in the inner walls of the outer pipes; the inner pipes are connected with the corresponding outer pipes in a sleeving mode, and guide grooves are formed in the side walls of the inner pipes; the two sets of sliding blocks are arranged in the corresponding inner pipes, rod cores are installed at the tops of the sliding blocks, guide blocks are arranged on the outer side walls of the sliding blocks, and the guide blocks penetrate through the guide grooves to be embedded into the guide rail grooves; the center block is of a double-end structure, the two ends of the center block are rotationally connected with the corresponding outer pipes in a sleeved mode respectively, and the two ends of the center block are connected with the corresponding inner pipes respectively. The utility model has the beneficial effects that the axial movement of the sliding block in the inner tube can be realized by rotating the tail block, so that the rod core can extend out when in use and can be recovered into the outer tube when not in use, the mistaken coating operation is avoided, and the use effect can be improved.
