Abstract
The utility model relates to a mechanical pencil, which comprises a pencil head and a pencil holder, wherein the pencil head is connected with the pencil holder; a gripping head is axially arranged in the pencil holder; the front end of the gripping head extending into the pencil head is provided with an elastic damping ring; and the front end of the central hole of the elastic damping ring is provided with a pencil lead protecting tube. The utility model is characterized in that the front end of the pencil lead protecting tube is sheathed with a rubber tube and pencil leads; a vertical inward contact of the rubber tube is inserted into an opening of one side of the front end of the pencil lead protecting tube; the rubber tube is matched with the pencil lead protecting tube for pressing the pencil leads arranged in the pencil lead protecting tube; or a rubber ring groove embedded in a rubber ring is formed around the front end of the pencil lead protecting tube. One side of the rubber ring groove is communicated with the pencil lead protecting tube. The utility model has the advantages of simple structure, convenient operation, economization, environment protection and obvious effect. When the mechanical pencil is used, the length of each remnant pencil lead can be reduced to less than 2 mm, the resource waste is effectively reduced, and the use is convenient.
Description
Technical field
The utility model relates to a kind of stationery, particularly a kind of propelling pencil.
Background technology
Now, the use of propelling pencil is very general, and it uses clean advantage easily to be subjected to student and other favors with a personnel deeply.In today that energy-conserving and environment-protective consciousness is progressively strengthened, more people recognize that there is the shortcoming of the wasting of resources in propelling pencil, promptly when pen core when using up, because the restriction of pencil self structure, there is the lead for retractable pencil of significant proportion not use to the end, just residual core must be arranged, can only waste.Statistics is found by inquiry, and the lead for retractable pencil length specification of China market is multiple from 60 millimeters to 120 millimeters, and the lead for retractable pencil that is wasted in the use to be residual core do not wait from 6 millimeters to 17 millimeters approximately, 1/10th wastes are arranged generally approximately.A lead for retractable pencil waste 1/10th, the whole nation has the people in hundred million will use propelling pencil every day, and it is exactly the appreciable wasting of resources that 1/10th of every lead for retractable pencil adds up, and number is surprising, and many grains of sand piled up will make a pagoda, the finest fragments of fox fur, sewn together, will make a robe, can't neglect.Based on this, develop a kind of propelling pencil that the waste of pen core can be reduced to minimum, will be one and both have very important energy-conservation effect to have the creation project of strengthening the environmental protection and energy saving idea again.
In fact, countries such as Japan, the U.S. have had residual core have been reduced to technology and product below 3 millimeters, because its manufacturing process is very high, the propelling pencil manufacturing enterprise of China can't have such technology.What therefore we produced ourselves mainly is low-grade propelling pencil, and the market price is about several units; The daily high-grade propelling pencil that can see is external import mostly, and market price does not wait more than dozens of yuan to hundred yuan.So based on the level of consumption of China, the sales volume of market propelling pencil mainly still is low-grade propelling pencil.
In sum, the residual core of low-grade propelling pencil is minimized, be to have pressing for of China's national situation.
The utility model content
The purpose of this utility model be to provide a kind of reasonable in design, easy to use, be beneficial to environmental protection, reduce the propelling pencil of lead for retractable pencil waste.
The technical scheme that the utility model adopted is for achieving the above object: a kind of propelling pencil, comprise that nib is connected with penholder, the coaxial chuck that is provided with in the described penholder, the front end that chuck stretches into pen head part is provided with the elastic damping ring, corresponding elastic damping ring centre bore front end is provided with the lead for retractable pencil pillar, it is characterized in that the sheathed sebific duct of described lead for retractable pencil pillar front end, in the opening that vertical inside contact insertion lead for retractable pencil pillar front end one side of its sebific duct is provided with, be mated and press the lead for retractable pencil that is provided with in the lead for retractable pencil pillar; Or lead for retractable pencil pillar leading section is around offering the aprons slot that embeds cushion rubber.
The beneficial effects of the utility model are: it is simple in structure, be easy to implement, and economical environment-protective, remarkably productive.During application, the length of every residual core can effectively reduce the wasting of resources with being reduced to below 2 millimeters, and very easy to use.The utility model easily forms product scale, standardized production.

Among the figure: 1 penholder, 2 nibs, 3 chucks, 4 elastic damping rings, 5 lead for retractable pencils, 6 lead for retractable pencil pillars, 7 sebific ducts, 8 openings, 9 aprons slots.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to the specific embodiment, structure, feature that foundation the utility model provides:
As Fig. 1～shown in Figure 5, a kind of propelling pencil, comprise that nib 2 is connected with penholder 1, the coaxial chuck 3 that is provided with in the described penholder 1, the front end that chuck 3 stretches into written 2 parts is provided with elastic damping ring 4, and corresponding elastic damping ring 4 centre bore front ends are provided with lead for retractable pencil pillar 6, it is characterized in that the sheathed sebific duct 7 of described lead for retractable pencil pillar 6 front ends, in the opening 8 that its sebific duct 7 vertical inside contacts insertion lead for retractable pencil pillar 6 front ends one sides are provided with, be mated and press the lead for retractable pencil 5 that is provided with in the lead for retractable pencil pillar 6; Or lead for retractable pencil pillar 6 leading sections are around offering the aprons slot 9 that embeds cushion rubber.
Described aprons slot 9 one sides communicate with lead for retractable pencil pillar 6.
By the cushion rubber in the sebific duct 7 that is provided with or the aprons slot 9, the lead for retractable pencil 5 in the spacing lead for retractable pencil pillar 6 causes to prevent that lead for retractable pencil 5 is too short to come off.
Above-mentioned detailed description of propelling pencil being carried out with reference to embodiment; be illustrative rather than determinate; can make various specification as required,, should belong within the protection domain of the present utility model therefore in the variation and the modification that do not break away under the utility model general plotting.
Claims (2)
1, a kind of propelling pencil, comprise that nib is connected with penholder, the coaxial chuck that is provided with in the described penholder, the front end that chuck stretches into pen head part is provided with the elastic damping ring, corresponding elastic damping ring centre bore front end is provided with the lead for retractable pencil pillar, it is characterized in that the sheathed sebific duct of described lead for retractable pencil pillar front end, in the opening that vertical inside contact insertion lead for retractable pencil pillar front end one side of its sebific duct is provided with, be mated and press the lead for retractable pencil that is provided with in the lead for retractable pencil pillar; Or lead for retractable pencil pillar leading section is around offering the aprons slot that embeds cushion rubber.
