Detailed Description

Referring to fig. 1-6, the present invention provides a technical solution: a tube-type separable multifunctional eraser comprises a separable eraser 1;

divisible rubber 1 includes pencil pipe 11, rubber sleeve 13 and rubber 12, fixed mounting rubber sleeve 13 in the pencil pipe 11, and the elastic internal thread 14 of rubber sleeve 13 inner wall integrated into one piece, the fixed parcel rubber 12 in the 11 outsides of pencil pipe, 11 internal rotations of pencil pipe are inserted and are installed pencil 2, according to the frictional force formula: f = μ × Fn shows that, with a constant friction coefficient, the pencil 2 receives an increased pressure and an increased friction force as the rotation advances, and the friction force increases until the pencil is firmly bonded.

In this kind of technical scheme, frictional force can constantly increase when can making pencil 2 rotate and insert in pencil pipe 11 through the design of elasticity internal thread 14 to thereby ensure to cut the stability when rubber 1 and pencil 2 make up, thereby insert the different positions of pencil 2 through can cutting rubber 1 and play different effects, and can cut rubber 1 can be nimble as required cut suitable length, improve the functional of traditional rubber.

Optionally, the central line of the pencil tube 11 and the central line of the pencil 2 are located on the same straight line, the inner diameter of the elastic internal thread 14 is smaller than the outer diameter of the pencil 2, and the outer side of the pencil tube 2 and the inner side of the rubber 12 can be connected by bonding or pouring, so that firm combination and unchanged elasticity are guaranteed.

Optionally, the pencil tube 11 is connected with the pencil 2 in a combined manner, the elastic inner thread 4 is flexibly connected with the pencil 2, the friction force between the pencil tube 11 and the pencil 2 can be adjusted through the screwing depth in use, and the outer surface of the pencil 2 cannot be damaged.

Example one

Referring to fig. 1-2, the separable eraser 1 can be sleeved on the top of the pencil 2 and used as an eraser 12 of the pencil 2 at the non-writing end, because the elastic internal thread 14 is adopted, the separable eraser is used as an anti-slip eraser head.

Example two

Referring to fig. 3 and 4, the cuttable eraser 1 can be sleeved on one side of the writing end of the pencil 2 to serve as an anti-slip cap and can also serve as a holding sleeve of the pencil 2, so that the anti-slip effect can be achieved during writing;

example three.

Referring to fig. 5 and 6, pencils 2 can be inserted into both ends of the separable eraser 1, and the separable eraser 1 can be connected with two groups of short pencils 2, can be used as a connector of the pencils 2 and can also be used as an extender of the pencils 2.

Optionally, the eraser 12 is of a cylindrical structure, and the shape of the eraser 1 can be designed as follows: the shape of the stick can be various shapes such as hexagonal, multi-ring, bamboo joint, multi-edge, calabash, baseball stick, animal, plant, natural landscape and cartoon, and characters and scales can be printed on the stick, so that the stick can be freely cut according to personal preference.

During the use, can at first cut into suitable length with can cutting the rubber 1 of can cutting according to the use purpose, can rotate later and insert through pencil 2 and get into and make up in pencil pipe 11 to accomplish the connection work of pencil 2 and can cut rubber 1, thereby it can cut rubber 1 and can install and play different effects on the different positions of pencil 2, can improve the functionality, it is more convenient to make the use of pencil, can also use as the extender of pencil, avoid shorter pencil 2 because of holding the inconvenient waste that often directly abandons and bring.
