Abstract
The utility model discloses a novel device capable of saving pens, which comprises an inner tube 1 and an outer tube2, wherein the inner tube 1 and the outer tube 2 are connected with each other via threads 3. The novel device capable of saving pens is characterized in that an opening 4 is arranged at the front end of the inner tube 1, a boss 5 is arranged at the rear end of the opening 4, a slope 6 is arranged on the front end inner side of the outer tube 2, and a reinforcing ring 7 is arranged on the front end outer side of the outer tube 2. The novel device capable of saving pens has the advantages of increasing usage of chalks and pencils and reducing environmental pollution.
Description
Technical field
The utility model relates to a kind of stationery, and specifically a kind of novel joint pen device is applicable to the clamping of chalk head, pencil stub.
Background technology
Office, school are in training and teaching process at present, the chalk that uses on the blackboard of dais, serve as a teacher with hand and be difficult to seize on both sides by the arms when writing, just it is thrown away, the pencil that mapping worker and student use also is when mapping worker and student are difficult to seize on both sides by the arms use with hand, also it is thrown away, chalk head and the pencil stub thrown away, the one, cause waste; The 2nd, cause the pollution of environment.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and improves chalk, pencil utilization rate, alleviates the novel joint pen device of environmental pollution.
For reaching above purpose, technical solution adopted in the utility model is: this novel joint pen device, constitute by interior pipe, outer tube, interior pipe and outer effective being threaded, it is characterized in that establishing opening, establish boss, establish gradient in outer tube front end inboard in the rear end of opening at the front end of interior pipe, for strengthening the intensity of outer tube, establish reinforcing ring in the outside.The utility model is also implemented by following measure, and the interior diameter of described interior pipe is consistent with the overall diameter of chalk, pencil, the gradient of outer tube front end inboard, and its angle is between 10-15 °.When using the utility model, left-handed outer tube, the overall diameter of the chalk of the interior diameter of pipe and clamping or pencil is identical in making, with chalk head or the pencil stub interior pipe of packing into, dextrorotation outer tube then, the outer tube reach makes pipe in the inboard gradient compression, chalk head and pencil stub are clamped, and hand-held outer tube writes or surveys and draws.
The beneficial effects of the utility model are: with directly write and compare at present with hand-held chalk, pencil, have and improve chalk, pencil utilization rate, alleviate the advantage of environmental pollution.
