Description
Technical field
The utility model relates to the stationery field, relates in particular a kind of pencil.
Background technology
The upper end of some pencil holders is fixed with rubber, and rubber is the upper end that is fixed on penholder by fixed cover, and namely the penholder upper end is fixed in the fixed cover lower end, and the rubber lower end is fixed in the fixed cover upper end.Because the material of rubber own is softer, can not be oversize so be fixed on the rubber of pencil holder upper end, otherwise in use rubber easily fractures.If but rubber is too short, although be not easy fracture, use not, when namely pencil was also surplus a lot, rubber just was finished, can not satisfy the user demand to rubber.In addition, for the pupil, if rubber is longer, when using rubber, owing to not grasping the weight of exerting oneself, also easily rubber is fractureed.
Summary of the invention
The purpose of this utility model provides a kind of pencil with rubber defencive function, makes the rubber that is fixed on pencil holder upper end have enough length and is not easy to fracture.
Pencil with rubber defencive function described in the utility model; comprise penholder, fixed cover and rubber, the penholder upper end is fixed in the fixed cover lower end, and the rubber lower end is fixed in the fixed cover upper end; be connected with protective sleeve at fixed cover, described rubber is positioned at protective sleeve and cooperates with the protective sleeve upper gap.
During use, the relative rotation by between protective sleeve and the fixed cover makes protective sleeve move axially along penholder, thereby regulates the length of the rubber that stretches out protective sleeve, and what make that the rubber length of stretching out namely can satisfy rubber conveniently uses and don't can be fractureed.Rubber can make in the rubber retraction protective sleeve with relative rotation between the fixed cover by protective sleeve after finishing using equally.
Pencil with rubber defencive function described in the utility model; owing to having set up the protective sleeve that spins with fixed cover; rubber can stretch out suitable length in use as required; and be protected the limiting protecting of cover; therefore it is longer that the length of rubber can have the length of Eraser with pencil holder now; and frangibility not, thereby satisfied requirement to the rubber use amount.In addition, after pencil uses to a certain degree, can hold the use that fixed cover and protective sleeve carry out pencil, therefore improved to a certain extent the utilization rate of pencil.

Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by coming by reference to the accompanying drawings.
As shown in Figure 1; this pencil with rubber defencive function comprises penholder 1, fixed cover 3 and rubber 2; penholder 1 upper end is fixed in fixed cover 3 lower ends; rubber 2 lower ends are fixed in fixed cover 3 upper ends; be connected with protective sleeve 4 at fixed cover 3, described rubber 2 is positioned at protective sleeve 4 and cooperates with protective sleeve 4 upper gap.
In use; relative rotation by between protective sleeve 4 and the fixed cover 3 makes rubber 2 upper ends that are fixedly connected with fixed cover 3 stretch out protective sleeve 4, and can use rubber 2 this moment; after finishing using, with relative rotation between the fixed cover 3 rubber 2 is retracted in the protective sleeve 4 by protective sleeve 4 again.
