The pencil tip is provided with a lengthways through hole which is movably connected with one end of the pencil cylinder. The pencil cylinder is provided with the other through hole which is comparative with the through hole of the pencil tip in size, and 1-3 sliding troughs are arranged on the through hole. The sliding block is arranged in the sliding trough of the through hole of the pencil cylinder, the sliding block is provided with the through hole, the through hole forms a column upwards, and the screw rod is pressed and connected to the column. The pencil cap is provided with a column-shaped bulge, and the column-shaped bulge extends into the inner part of the through hole of the pencil cylinder and is pressed and connected to the screw rod, presenting a clamping connection mode with the pencil cylinder. The pencil core is arranged in the through hole, one end of the pencil core is spliced in the through hole of the sliding block, and one end of the pencil core extends out of the through hole of the pencil tip. A stopping sliding block is arranged at the site of the sliding trough of the pencil cylinder approaching to the pencil tip. Compared with the prior art, the utility model is the pencil which is convenient in writing, is not easy to break in a pencil core, does not need the wood, and saves natural resource.

Description

Pencil

Technical field

The utility model relates to the school supply and stationery technical field, specifically, relates to a kind of being applicable to the device that just can write behind the pencil-lead is installed.

Background technology

The structure of known pencil roughly is such, by pencil-lead, surround pencil-lead and form with the close-connected lumber layer of pencil-lead, rubber sassafras on can being connected at an end of pencil is during use, the lumber layer of cutting out pencil with cutter exposes pencil-lead, just can be used to write, operation such as picture.

Traditional pencil will consume a large amount of timber, and imperative to the transformation of traditional pencil along with the attention to the forest reserves, the starting point of its transformation mainly is: first will keep the major functions such as the easy wiping of writing of pencil; Seek the substitute of timber; The secondth, keep pencil-lead, realize the writing function of pencil with other device.

Known energy substitutes wood pencil and has only used for reference the structure of ball point pen with the device of pencil-lead to a great extent, but pencil-lead easily splits off, writes inconvenience when being to use, and manufacturing cost is also higher.

The utility model content

Goal of the invention of the present utility model is intended to overcome above-mentioned prior art defective, provides a kind of and can write conveniently, pencil-lead is difficult for splitting off and do not need timber, save the pencil of natural resources.

Goal of the invention of the present utility model is achieved by the following technical programs: pencil is by nib, pen container, the cap for brush, fixator, slide block, screw mandrel, pen core is formed, nib has a longitudinal hole, and be movably connected in an end of pen container, pen container also is provided with size another through hole suitable with the nib through hole, also be provided with 1-3 root chute on this through hole, slide block is arranged in the chute of pen container through hole, also be provided with through hole on the slide block, through hole upwards forms a post, screw mandrel one end withstands on the post, also be provided with a columnar protrusions on the cap for brush, this columnar protrusions stretches in the through hole of pen container and is crimped on the screw mandrel, pen core is arranged in the through hole, and an end is plugged in the through hole of slide block, and an end stretches out the through hole of nib; On the chute of pen container, also be provided with a limited slip block near the nib place.

Compared with prior art the utlity model has write conveniently, pencil-lead is difficult for splitting off and do not need timber, save the pencil of natural resources; The utility model also has low cost of manufacture, is easy to suitability for industrialized production.

Description of drawings

Fig. 1 is a sectional structure schematic diagram of the present utility model;

Fig. 2 is an assembly structure schematic diagram of the present utility model;

Mark among the figure: 1 nib, 2 pen containers, 3 caps for brush, 4 fixators, 5 screw mandrels, 6 pen cores, 7 through holes, 8 chutes, 9 slide blocks, 10 posts, 11 columnar protrusions, 12 limited slip blocks.

The specific embodiment

Embodiment 1: pencil is by nib 1, pen container 2, the cap for brush 3, fixator 4, screw mandrel 5, pen core 6 is formed, nib 1 has a longitudinal hole 7, and be movably connected in an end of pen container 2, pen container 2 also is provided with size and another suitable through hole 7 of nib 1 through hole 7, also be provided with 2 chutes 8 on this through hole 7, slide block 9 is arranged in the chute 8 of pen container 2 through holes 7, also be provided with through hole 7 on the slide block 9, through hole 7 upwards forms a post 10, screw mandrel 5 one ends withstand on the post 10, also be provided with a columnar protrusions 11 on the cap for brush 3, this columnar protrusions 11 stretches in the through hole 7 of pen container 2 and is crimped on the screw mandrel 5, pen core 6 is arranged in the through hole 7, and an end is plugged in the through hole 7 of slide block 9, and an end stretches out the through hole 7 of nib 1; On the chute 8 of pen container 2, also be provided with a limited slip block 12 near nib 1 place; Compared with prior art the utlity model has write conveniently, pencil-lead is difficult for splitting off and do not need timber, save the pencil of natural resources; The utility model also has low cost of manufacture, is easy to suitability for industrialized production.

The rotation cap for brush 3 during use, because the rotation of screw mandrel 5, slide block 9 moves up and down in chute 8, makes pen core 6 expose nib 1 length adjustment to best; The time spent reverse rotation cap for brush 3, in 6 withdrawals of pen core nib 1, use up as pen core 6, take off nib, the rotation cap for brush 3, and slide block 9 slides into limited slip block 12 places, and fixator 4 exposes outside the pen container 2, changes new pen core 6 and gets final product.
