Description

Split type eraser and eraser combination

The technical field is as follows:

the utility model belongs to the stationery field, in particular to piece formula eraser and eraser combination, especially can tear an eraser a slice at the use, keep terminal surface limit arris sharp.

Background art:

the eraser is common stationery for the public, is seriously worn after being used for wiping pencil handwriting with soft texture, and is hard to control because edges of corners and end faces are not wiped to be rounded and finally a round end part is formed, so that wiping traces become wide, the range is enlarged and the pencil handwriting is difficult to control. The simplest method is to cut the round enlarged end with a knife to form a new end with sharp edges for fine wiping. Due to the fact that the primary school students do not often wear the small knife and do not feel safe when wearing the small knife, much inconvenience is brought to practical use.

How to solve the problem that the rubber wearing brings inconvenient use, namely becomes the object of the research of the utility model.

The invention content is as follows:

the utility model aims at designing a piece type eraser which can be torn off one by one and a piece type eraser combination.

The utility model discloses technical scheme realizes like this: the piece-separating eraser is characterized in that: the eraser body is strip-shaped, a plurality of cutting seams are arranged along the length direction, and the bottom of each cutting seam is provided with an adhesion part.

The section of the eraser main body is of a rectangular structure, and the adhering part of the cutting seam is positioned on one side of one long side of the rectangle.

The split type eraser combination comprises the split type eraser and a push-pull box; a sliding groove is formed in one surface of the push-pull box, and a sliding push button is arranged in the sliding groove; the method is characterized in that: the eraser main body is arranged in the push-pull box, and a sliding push button arranged on the push-pull box is embedded in the eraser main body and can drive the eraser main body to slide synchronously; the two edges of the sliding groove of the push-pull box are used for restricting the scale interval of the sliding push button and are equal to the distance of the cutting seam of the eraser main body.

The eraser main body is restrained in the push-pull box by the sliding push button, and when the end part of the eraser main body goes in and out of and stays at the port of the push-pull box, the plane of the port is positioned between the two cutting seams of the eraser main body.

The peripheral surface of the port of the push-pull box is provided with a chamfer to form a tapered port.

The utility model has the characteristics of ingenious conception, reasonable design and convenient use; the eraser main body not only has a piece cutting seam, but also is an adhesive whole body, and can be torn off at any time according to the requirement, so that the edge of the new port is kept sharp, and finer marks can be accurately wiped; the split type eraser combination is matched with the push-pull box to form a split type eraser combination, so that the eraser main body can be protected, the force is convenient to use, the cutting seam is not accidentally broken, the use efficiency and the enjoyment are greatly improved, and the split type eraser combination is particularly suitable for being used by low-grade students without knives.

Description of the drawings:

the present invention will be further explained with reference to the following specific drawings:

FIG. 1 is a schematic view of a piece-separating type eraser

FIG. 2 is a schematic view of the bending of the divided eraser

FIG. 3 is a schematic view of the combination of the divided eraser

Wherein

1-eraser main body 11-cutting seam 12-adhering part

2-push-pull box 21-chute 22-scale interval 23-port

3-sliding button

The specific implementation mode is as follows:

referring to fig. 1 and 2, the divided type eraser has a strip-shaped eraser body 1, which has a plurality of slits 11 along the length direction, and an adhesive part 12 is left at the bottom of the slits to maintain the integrity of the eraser body and to be easily bent and deformed as shown in fig. 2.

Further, the section of the eraser body 1 is rectangular, and the adhesion part 12 of the cutting seam 11 is positioned on one side of one long side of the rectangle, so that the eraser body can ensure that the adhesion is long enough, and is relatively thin and easy to tear.

Referring to fig. 3, the divided eraser assembly includes the divided eraser body 1 and the push-pull box 2; a sliding groove 21 is arranged on one surface of the push-pull box 2, and a sliding push button 3 is arranged in the sliding groove 21; the sliding groove 21 is provided with a scale space 22 along both edges thereof, and the sliding push button 3 is restrained by the scale space 22, i.e. the sliding push button 3 is positioned, but the sliding action of the sliding push button 3 is not hindered.

The eraser body 1 is arranged in the push-pull box 2, and a sliding push button 3 arranged on the push-pull box is embedded in the eraser body 1 and can drive the eraser body 1 to slide synchronously so as to adjust the length of a port 23 extending out of the push-pull box 2; because of the split structure with the eraser body 1, for this purpose, the scale interval 22 with the chute has the following relationship: the scale interval 22 at the two edges of the sliding groove 21 of the push-pull box is equal to the interval of the rubber body cutting seam 11. And the eraser main body 1 is restrained in the push-pull box 2 by the sliding push button 3, when the end part enters and leaves and stays at the port 23 of the push-pull box, the plane of the port 23 is positioned between two slits 11 of the eraser main body, namely the slits 11 are staggered with the plane of the port 23, so that the slits 11 are prevented from being flush with the port 23, and the force wiping can be prevented from being broken unintentionally.

Furthermore, the peripheral surface of the port 23 of the push-pull box is provided with a chamfer to form a tapered port, so that the paper surface is prevented from being scraped during wiping.
