Abstract
The utility model discloses a telescopic pencil lengthening sleeve. The telescopic pencil lengthening sleeve comprises an inner sleeve pipe and outer sleeve pipe, wherein the outer diameter of the inner sleeve pipe is less than the inner diameter of the outer sleeve pipe; the inner walls of the head parts of the inner sleeve pipe and the outer sleeve pipe are respectively provided with a spring piece; when the inner sleeve pipe extends into the outer sleeve pipe, the spring piece on the inner wall of the outer sleeve pipe can clamp the inner sleeve pipe firmly, so that the inner sleeve pipe and the outer sleeve pipe are reliably connected; simultaneously, the inner sleeve pipe can move in the outer sleeve pipe only by using a little force; when the head part of the inner sleeve pipe is sheathed with a short pencil, the inner sleeve pipe is moved outwards from the outer sleeve pipe, and the inner sleeve pipe and the outer sleeve pipe are combined to be longer so as to be suitable for being used by the short pencil; when the head part of the inner sleeve pipe is sheathed with a longer pencil, the inner sleeve pipe is moved into the outer sleeve pipe, and the inner sleeve pipe and the outer pipe are combined to be shorter so as to be suitable for being used by the longer pencil; and the pencil can be reliably arranged on the inner sleeve pipe by the spring piece arranged on the inner wall of the head part of the inner sleeve pipe. The telescopic pencil lengthening sleeve disclosed by the utility model can also be used by flat short pencils for woodworking and the like.
Description
Technical fieldThe utility model relates to a kind of cover, specifically relates to a kind of telescopic pencil elongated cap.
Background technologyFor the adult, when pencil when only surplus approximately 7cm is long, use just not very comfortablely, be difficult for accurately controlling pencil; Pencil about length 15cm uses relatively comfortable; So when pencil length during at 7-10cm visual feelings with cover with pencil elongated, but on the market special-purpose pencil elongated cap is arranged seldom now; Some people just substitutes with other sleeve pipe, but these not flexibles of alternative sleeve pipe also can be suitable for very short pencil (such as the pencil about 2cm) or relatively long short pencil (such as the pencil of 7-10cm) simultaneously with regard to being difficult to, and are not very comfortable otherwise use.And the short flat pencil that the carpenter is used, these alternative sleeve pipes just can't have been used.In addition, these alternative sleeve pipes neither be once having looked for, and because can not find these alternative sleeve pipes, many people need not abandon 5cm even longer short pencil, thereby have caused unnecessary waste.
Summary of the inventionThe utility model purpose: be to provide a kind of telescopic pencil elongated cap for addressing the above problem.
The utility model purpose is achieved in that a kind of telescopic pencil elongated cap is made of inner sleeve and outer tube, and described inner sleeve is longer than outer tube, and described inner sleeve external diameter is less than the outer tube internal diameter; Be respectively equipped with at least more than one spring leaf on described inner sleeve and the outer tube head inwall, this spring leaf middle part is arch shape; Described outer tube afterbody is provided with bonnet.
The beneficial effects of the utility model: because of the utility model flexible, both applicable very short pencil also was suitable for long short pencil; In addition, also be suitable for the short flat pencil of the usefulness such as carpenter.Not only make things convenient for people's use, reduced simultaneously the waste of pencil, saved resource and the energy.
Description of drawingsFig. 1 is the utility model structural representation.
The specific embodimentNow by reference to the accompanying drawings the utility model is done further narration.
As shown in Figure 1,1. spring leaf, 2. inner sleeve, 3. outer tube, 4. bonnet.
A kind of telescopic pencil elongated cap is made of inner sleeve 2 and outer tube 3, and described inner sleeve 2 is longer than outer tube 3, and described inner sleeve 2 external diameters are less than outer tube 3 internal diameters; Be respectively equipped with at least more than one spring leaf 1 on described inner sleeve 2 and the outer tube 3 head inwalls, this spring leaf 1 middle part is arch shape; Described outer tube 3 afterbodys are provided with bonnet 4.
The external diameter of inner sleeve 2 can be arranged more smaller than the internal diameter of outer tube 3, inner sleeve 2 is connected with outer tube after the connection, except inner sleeve 2 heads, most of body of inner sleeve 2 can put in the outer tube 3, the spring leaf 1 that is arranged on the outer tube 3 head inwalls can clip inner sleeve 2, and inner sleeve 2 is connected reliably with outer tube 3; Simultaneously, people are as long as exert oneself a little (be people firmly greater than the folder power of 1 pair of inner sleeve 2 of spring leaf time), and inner sleeve 2 can be in outer tube 3 interior movements.When in inner sleeve 2 heads very short pencil being installed, then inner sleeve 2 can be moved in outer tube 3 outward, make inner sleeve 2 and outer tube 3 make up longlyer, to be fit to the very use of short pencil; When long short pencil is installed in inner sleeve 2 heads, then with inner sleeve 2 past outer tube 3 interior movements, make inner sleeve 2 and outer tube 3 make up shortlyer, to be fit to the use than the length pencil.At the spring leaf 1 that inner sleeve 2 head inwalls arrange, pencil can be installed on the inner sleeve 2 reliably.
Inner sleeve 2 and outer tube 3 are made the lengthening cover of circular tube shaped, can be for pencils such as circle or hexagons; Inner sleeve 2 and outer tube 3 are made the lengthening cover of elliptic flat tube shape, then can be for the flat pencil of the usefulness such as carpenter.
