Problems solved by technology
[0003] The current pencil and the eraser at the end are fixedly connected by aluminum foil, and the disassembly process is almost irreversible. Moreover, with the use of the pencil, half of the aluminum foil will remain unusable, resulting in waste. At the same time, the aluminum foil and the eraser are imprisoned at the end of the pencil. , it is inconvenient to assemble and disassemble, so it is necessary to design an eraser quick-installation device to solve this technical problem

The invention relates to the field of articles of everyday use, in particular to a detachable eraser connector suitable for ends of pencils of multiple specifications. The detachable eraser connectorcomprises a pencil body and an eraser, a connecting device for connecting the pencil body with the eraser is arranged between the pencil body and the eraser, the connecting device comprises a sleeve,an eraser push mechanism and a pencil rod locking mechanism, the eraser push mechanism comprises an upper turncap and an upper push disc, and the inner wall of the upper turncap and the outer edge ofthe upper push disc are in threaded connection. The pencil rod locking mechanism comprises a lower turncap, a lower push disc and a lock ring, the lower turncap is rotationally arranged on the outer side of the other end of the sleeve, the lower push disc is movably arranged on the inner side of the sleeve, and the inner wall of the lower turncap and the outer edge of the lower push disc are in threaded connection. According to the detachable eraser connector suitable for ends of the pencils of multiple specifications, waste of the eraser is effectively avoided in a thread extruding manner, and meanwhile the aim of fast demounting and mounting the detachable eraser connector and the pencil body is achieved through the tightening function of the lock ring.
Description
technical field [0001] The invention relates to the field of daily necessities, in particular to a detachable eraser connector suitable for the ends of pencils with multiple specifications. Background technique [0002] Pencil is a kind of pen used for writing and drawing and sketching. It has a history of more than 400 years. Among them, pencils for drawing and sketching are divided into many types. It is divided into three stages of development, namely graphite, wood Pencil holders and pencils with caps. The production of pencils is divided into two parts: the pencil cap and the pencil shaft: the main material for the appearance and decoration of the pencil cap is polyester material. The production process can be divided into mold making, offset printing, assembly and other processes to complete it. The exterior decoration materials of the pencil shaft mainly include nitrocellulose pencil paint, printing ink, anodized aluminum foil, rubber head and aluminum hoop. The prod...
