Description

Double-end interchangeable sheath and contain its pen

Technical Field

The application relates to the technical field of writing tools, in particular to a double-head interchangeable sheath and a pen containing the same.

Background

The pen is a frequently used writing tool, the pen holder is generally made of hard materials such as hard plastics or metals, and the pen holder is in hard contact with the hand for a long time, so that the hand can be pressed against the hand to cause pain of the finger, and the hand feel is uncomfortable; in order to overcome the defects, the pen cap made of a flexible material is sleeved on the pen holder in the prior art, so that the technical problems are solved; however, at present, a silica gel sleeve is adopted to be directly sleeved on a pen holder, and although the condition of pressing hands can be reduced to a certain extent, the hardness of the pen is fixed once sleeved, so that the pen cannot adapt to the use requirements of different people: if the pen cap is used by an adult, the hardness of the pen cap only needs to be properly reduced, the adult has stronger adaptability, and the special soft pen cap is not needed; however, if the pen is used by infants, especially the child who just learns, the force and angle of holding the pen for the first time can not be controlled skillfully, the pen can be held more compactly easily, which inevitably leads to larger stimulation of the pen cap to the hand, which easily leads to pain of the hands, and increases discomfort.

Disclosure of utility model

The present application addresses the above-described deficiencies of the prior art by providing a dual-ended interchangeable sheath having two different durometers that can be interchanged for different usage groups to meet different usage requirements.

In order to solve the technical problems, the application adopts the following technical scheme: the utility model provides a double-end interchangeable sheath, the structure of this sheath includes along the first cover body and the second cover body of axial connection in order, first cover body and second cover body be used for with the pen-holder cover to be fit, the inner wall of first cover body on be provided with unsmooth texture, the inner wall of second cover body be smooth inner wall, the internal diameter of first cover body with the internal diameter constant diameter of second cover body, and with the outer profile looks adaptation of the pen-holder of cover.

By adopting the structure, the sheath is sleeved on the penholder, and the whole sheath is divided into two sections, wherein concave-convex textures are arranged on the inner wall of the first sheath body, the radial thickness of the first sheath body can be thinned due to the arrangement of the textures, gaps can be generated between the concave-convex textures and the penholder, and when the first sheath body is held, a clearance space is reserved, so that the concave-convex textures are not contacted with the penholder, and the hand feeling softness of the whole first sheath body is improved; the inner wall of the second sleeve body is smooth, and the inner wall is directly contacted with the pen holder, so that no gap exists, and the inner wall and the pen holder are directly contacted and sleeved, so that the second sleeve body has low hand feeling softness and high relative hand feeling hardness compared with the first sleeve body when being held; thus, two structures with different hand feeling hardness or hand feeling softness can be realized on one sheath, and the structure is in actual use: if the pen is used by infants, the first sleeve body with relatively small hardness can be downwards sleeved on the pen holder, and then the first sleeve body is contacted with fingers, and the arrangement of concave-convex textures has the clearance position, so that the softness of the hand feeling is improved, and the use requirement of the infants on the hardness of the pen cap can be met; if the pen is used by an adult, the second sleeve body with relatively higher hardness can be downwards sleeved on the pen holder, and the second sleeve body contacts with the fingers at the moment, so that the use requirement of the adult on the hardness of the pen cap can be met; therefore, the sheath with two hardness structures can meet the requirements of use scenes with different hardness requirements, and is more convenient and convenient.

Further, the first sleeve body and the second sleeve body are integrally formed; by adopting the structure, the firmness of the integral sheath is improved, and the integral sheath is not easy to damage in the process of sleeving or separating with the pen holder.
