Abstract
The utility model relates to a single spiral propelling pencil, which belongs to the culture goods technology field. The utility model comprises a pencil tip, a pencil holder which are matched and connected mutually and an internal pencil core. The utility model is characterized in that the center of the pencil tip is fixedly connected with one end of a spiral core pin, the pencil core is threaded in the spiral core pin, a nose spike with a convex pin is arranged at the rear end of the pencil core in a matching way, an inner sleeve with a clipping groove is arranged in the pencil holder in a matching way, the convex pin is extended out of the spiral core pin and glidingly matched with the clipping groove, and spirally and glidingly matched with the spiral core pin. The single spiral propelling pencil has the advantages that the design is novel, the structure is reasonable, and the wood holder pencil with the thick pencil core can be replaced with the single spiral propelling pencil, the timber source is saved, in addition, the spiral type pencil core pushing structure is adopted, therefore the operation is convenient, the core ejecting length can be adjusted through stepless regulation and smooth regulation, the pencil core can be fully utilized, the lead pollution caused by disposed pencil core is reduced, and the single spiral propelling pencil is favorable for the protection of the ecological environment.
Description
Technical field
The utility model belongs to the cultural goods technical field, is specifically related to a kind of single-screw propelling pencil.
Background technology
Existing propelling pencil generally all adopts press type, in join back-moving spring, folder lead for retractable pencil with parts such as the chucks of blooming, the product structure more complicated, in the use last remaining have grow one section lead for retractable pencil and can not utilize, particularly can only be applicable to thin lead for retractable pencil.The lead bullion core is at present substantially still based on the rod structure, need cut during use, time-consuming, effort, and the same very long one section problem that lead for retractable pencil can't use at last that exists, not only waste timber resources, also contaminated environment is especially discarded out of use lead for retractable pencil and can be brought lead contamination, and ecological environment is had a strong impact on.
The utility model content
The utility model aims to provide a kind of simple in structure, single-screw propelling pencil technical scheme of being specially adapted to the lead bullion core, to overcome problems of the prior art.
Described single-screw propelling pencil, comprise the nib, penholder and the built-in lead for retractable pencil that are connected, it is characterized in that written center fixedlys connected with spiral core bar one end, the lead for retractable pencil cross-under is in the spiral core bar, the lead for retractable pencil rear end is equipped with the thimble with protruding nail, be equipped with the interior cover of band screens groove in the penholder, protruding nail stretches out the screens groove cunning of spiral core bar and interior cover joins, with spiral core bar spiral slide movingly.
Described single-screw propelling pencil is characterized in that penholder and interior cover are the split fit structure or directly offer the screens groove at the penholder inwall.
Described single-screw propelling pencil is characterized in that clamping is rotatably assorted between nib and the penholder.
Described single-screw propelling pencil is characterized in that being equipped with rubber ring in the cavity between spiral core bar and the nib, and described rubber ring is connected with spiral core bar, written close-fitting.
Described single-screw propelling pencil, its feature touch with the lead for retractable pencil rear end face at the horizontal end face of thimble and cooperate.
Described single-screw propelling pencil, its feature touch with the lead for retractable pencil rear end face at the horizontal end face of thimble and cooperate.
Above-mentioned single-screw propelling pencil is novel, rational in infrastructure; place of crude lead for retractable pencil Wood-bar pencil fully; save timber resources; and adopt spiral lead for retractable pencil to pass structure; use simple and direct, can stepless, smooth adjusting knockout length, and can make full use of lead for retractable pencil; minimizing helps the protection of ecological environment by the lead contamination that discarded lead for retractable pencil causes.
