Abstract
The utility model discloses a rotatable pencil sleeve with a nut, in terms of which the length of a rubber can be reduced or extended in a telescoping manner as the pencil is being used. The rotatable pencil sleeve with a nut is characterized in that the rotatable pencil sleeve comprises a large sleeve pipe, a small sleeve pipe and a rubber; the external surface of the small sleeve pipe is provided with a screw slot, and the inner surface of the large sleeve pipe is provided with another screw slot, and the two screw slots are occluded. The large sleeve pipe can slide up and down on the external surface of the small sleeve pipe along with the screwing, and thereby the length of the rubber can be adjusted. When the pencil is nearly used up, the large sleeve can be screwed upwardly, extending the length of the pencil, and thereby a pencil head can still be used, and the pencil is resources-saving and environment-friendly.
Description
Affiliated field: the invention belongs to cultural goods, particularly a kind of Rotatable pencil sleeve with nut.
Background technology: point protector is installed in the top of pencil, is the auxiliary products of pencil, and its effect is that rubber is installed, and realizes the convenience of writing.The pen cap of existing pencil with rubber all is to be positioned at the pencil top, and the length of rubber is fixed, and rubber generally all can not satisfy the needs of the use of pencil, and pencil also is not finished often, and rubber has not had, and this has brought inconvenience to use.
Summary of the invention: the size that the objective of the invention is to invent a kind of rubber can be with the use of the pencil a kind of Rotatable pencil sleeve with nut of its length that stretches.The present invention realizes as follows: the present invention includes large sleeve pipe, small casing and rubber, the outer surface of small casing has flight, the inner surface of large sleeve pipe has flight, the two phase interlock, large sleeve pipe can be in the slip up and down of the outside of small casing along with turning, thereby realizes the adjusting to rubber length.
The invention has the beneficial effects as follows, prolong the length of the rubber of pencil, and its length can regulate by the sleeve pipe on the nut, effectively cooperate the use of pencil.When pencil ran low, large sleeve pipe upwards turned, and the length of pencil is stretched, and makes pencil stub can also as usual use economical environment-protective.
Description of drawings: Fig. 1 is a kind of structure chart of the Rotatable pencil sleeve with nut
Fig. 2 is a kind of with the rubber structure chart on the Rotatable pencil sleeve of nut
Among Fig. 1: 1, the flight of the flight 5 of pencil 2, rubber 3, small casing 4, small casing outer surface, large sleeve pipe 6, large internal surface of casing
Among Fig. 2: 2, the base of rubber 7, rubber
Embodiment: as shown in Figure 1, the present invention includes pencil 1, rubber 2, small casing 3 and large sleeve pipe have flight 4 at the outer surface of small casing, and the inner surface of large sleeve pipe has flight 6.During use, rubber 2 is fixed on the small casing 3 by its base, large sleeve pipe 5 can be done slip up and down at the flight 4 of small casing outside by its flight 6, thereby realize the adjusting to rubber length, when rubber is not enough, large sleeve pipe down sliding from and skid off new rubber, practical and convenient.In Fig. 2, base 7 is arranged at rubber 2 bottoms, and the diameter of rubber 2 is identical with the overall diameter of small casing 3 among Fig. 1, is conducive to turning up and down between the fixing and sleeve pipe of rubber.When pencil ran low, large sleeve pipe 5 upwards turned by the flight 4 of flight 6 along small casing 3, and the length of pencil is stretched, and makes pencil stub can also as usual use economical environment-protective.
