Abstract
The utility model discloses a pencil stub using machine which comprise a holding handle and a pencil stub clamping device arranged on the lower end portion of the holding handle. The pencil stub clamping device is provided with a pencil stub insertion hole. An open-close clamping groove is formed in the lower portion of the pencil stub clamping device in the longitudinal direction. The pencil stub clamping device clamps a pencil stub tightly, thus, the length of the pencil stub is increased, so that holding is convenient. Consequently, the utilization length of the pencil stub is increased, and waste of resources is reduced.
Description
Technical field
The utility model relates to a kind of pencil stub and uses device.
Background technology
After pencil used certain hour at present, its remainder will be dropped owing to directly grip inconvenience with hand.General pencil has used with regard to inconvenience when residue 3～7cm according to statistics, and its length is equivalent to the 15%-35% of pencil total length, can cause the waste of a large amount of social resources after abandoning.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of pencil stub that can take full advantage of pencil stub and uses device.
For solving the problems of the technologies described above, the utility model comprises grab handle and the pencil stub clamping device that is installed on the grab handle bottom, and described pencil stub clamping device is provided with the pencil stub plug-in opening, and pencil stub clamping device bottom vertically is provided with the folding holding tank along it.
After adopting said structure, the pencil stub clamping device clamps pencil stub, has increased the length of pencil stub like this, and it is convenient to grip, thereby has increased the use length of pencil stub, reduces the waste of resource.
The lower end of described grab handle is provided with connecting hole, and pencil stub clamping device spiral shell is contained in the connecting hole.
The corresponding folding holding tank of the connecting hole inner surface of described grab handle place is provided with annular groove, be provided with the chucking circle in the annular groove, when pencil stub is plugged in the pencil stub clamping device, be provided with the pencil stub clamping device distending of folding holding tank section, the chucking circle will be provided with the pencil stub clamping device clamping of folding holding tank section this moment, guarantee that the pencil stub clamping device clamps pencil stub, prevents from use producing loosening.
The upper end of described grab handle is provided with the through hole that is communicated with connecting hole, be fitted with push rod in the through hole, the pencil stub plug-in opening runs through the two ends of pencil stub clamping device and its internal diameter greater than the internal diameter of through hole, when the pencil that exposes can eject the continuation use with the part that push rod will remain in the pencil stub clamping device with the light time soon, when pencil stub is used the limit, can directly eject with push rod, thereby solve the problem that pencil stub takes out difficulty.
Be set with the spring of reset response on the described push rod, be connected with the compact heap for extrusion spring on the push rod, the grab handle upper end snail is connected to spring and compact heap is enclosed in gland in the grab handle, gland is stretched out in the push rod end, after pressing push rod, push rod automatically resets under the effect of spring, and is easy to use.
The upper end internal diameter of described pencil stub plug-in opening reduces gradually, and better the lead gripper nib prevents that it is loosening.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, pencil stub uses device to comprise grab handle 1, establish connecting hole in the lower end of grab handle 1, the epimere inner surface of connecting hole is provided with screw thread, be screwed with pencil stub clamping device 2 in the connecting hole, pencil stub clamping device 2 is provided with pencil stub plug-in opening 11, arbitrary cross section of pencil stub plug-in opening 11 is that the internal diameter of regular hexagon and its upper end reduces from bottom to top gradually, pencil stub plug-in opening 11 runs through the two ends of pencil stub clamping device 2, pencil stub clamping device 2 bottoms vertically are provided with two folding holding tanks 3 along it, two folding holding tanks 3 are symmetrical arranged, the length of folding holding tank 3 guarantees it, and some is positioned at connecting hole, the corresponding folding holding tank of connecting hole inner surface 3 places are provided with annular groove 4, be provided with chucking circle 5 in the annular groove 4, the internal diameter of chucking circle 5 is slightly less than the external diameter of corresponding position pencil stub clamping device 2, thereby auxiliary pencil stub clamping device 2 well clamps pencil stub, and chucking circle 5 can use flexible rubber ring.The upper end of grab handle 1 is provided with the through hole 12 that is communicated with connecting hole, be fitted with push rod 6 in the through hole 12, the internal diameter of through hole 12 is less than the internal diameter of pencil stub plug-in opening 11, and through hole 12 forms boss with the connecting hole junction and can well prevent from moving up in the through hole 12 on the stressed back, pencil stub lower end.Grab handle 1 upper end arranges the counterbore 7 with through hole 12 concentric settings, be set with the spring 8 of reset response on the push rod 6 of counterbore section, be connected with the compact heap of establishing along its radial loop 9 that is used for extrusion spring 8 on the push rod 6, grab handle 1 upper end outer surface is bolted with spring 8 and compact heap 9 is enclosed in gland 10 in the grab handle 1, and gland 10 is stretched out in push rod 6 ends.
The above is preferred embodiment of the present utility model only, is not limited to the utility model.Previous embodiment has been described in detail the utility model, and for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.In every case within inventive concept scope of the present utility model, any modification of making, be equal to replacement, improvement etc., all be included within the protection domain of the present utility model.
