Abstract
An eraser in the field of stationery comprises a screwed pipe clamp and a necking shell, and is characterized in that: the taper of the outer wall of the front end of the straight-through slotting chuck of the screwing pipe clamp is larger than that of the inner wall of the front end of the necking shell. The simplified eraser locking mechanism is more reliable, flexible and excellent in effect.
Description
Technical Field
The invention relates to an eraser in the field of stationery.
Background
In prior art WO/2019/112637, JP2018-114758A, CN209649856U, CN202541134U, CN2811012Y and CN2423116Y, the eraser is more complicated in structure and parts are not easy to lock.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the eraser simplifies the structure, reduces the manufacturing cost and avoids the eraser from sliding to ensure the reliable and convenient use of the locking mechanism.
The technical scheme of the invention is as follows: the eraser comprises a screwed pipe clamp with threads and a necking shell, and is characterized in that: the taper of the outer wall of the front end of the straight-through slotting chuck of the screwing pipe clamp is larger than that of the inner wall of the front end of the necking shell.
The invention has the beneficial effects that: the eraser with the omitted elements has the advantages of simple structure, less parts, low cost and excellent effect of realizing more stable locking of the eraser, simple and convenient operation, labor saving and easy replacement of the eraser.
Drawings
FIG. 1 is a schematic view of the structure of the eraser.
In the figure: 1 long rubber, 2 screwing pipe clamp and 3 necking shell.
Detailed Description
Referring to fig. 1, the upper end of the reducing casing 3 is provided with an internal thread and the lower end is formed into a reducing taper shape, and the upper end of the screwing pipe clamp 2 is provided with an external thread and the outer wall of the lower end slotting clamp is formed into a taper shape. A movable clearance is formed between the inner diameter of the necking shell 3 and the outer diameter of the screwing pipe clamp 2, and a movable clearance is formed between the inner diameter of the screwing pipe clamp 2 and the outer diameter of the long rubber 1. When the eraser is used, the upper part of the screwing pipe clamp 2 is reversely screwed, the outer wall cone of the spirally rising slotted chuck is separated from the inner wall cone of the necking shell 3 to be in close contact, the loosened strip-shaped eraser 1 is exposed out of the necking shell 3, then the screwing pipe clamp 2 is screwed to lock the strip-shaped eraser 1 again, and the plastic rod pen combined eraser is more convenient to apply.
