The working end, the swivel joint is located on one of the working ends of the base body, the working end is the joint end of the pen holder, and the nib interface is located at the other working end of the base body, the working end is the nib joint end, which is used for connecting with the nib The connecting part is connected; the outer surface of the rotary joint is an arc surface, and the end of the pen holder has a connecting seat adapted to the rotary joint so that the rotary joint can be rotated and positioned in the connecting seat. Users can adjust the angle of the nib according to their own hand shape and writing habits, which can meet the needs of different writing groups.

Description

technical field [0001] The invention relates to a writing pen, in particular to a multifunctional pen with an adjustable pen head angle. Background technique [0002] Most of the existing writing pens are coaxial pens, that is, the central axis of the pen holder and the nib are on the same axis. At present, there are also non-axial pens on the market. As the name suggests, the non-axial pen is the central axis of the pen holder and the nib. not on the same axis. The coaxial pen has the following defects in the process of use: (1) because of the gravity, when the coaxial pen is used for writing, the human hand needs to hold it hard, which is easy to cause soreness and fatigue in the arm; (2) the coaxial pen is easy to As a result, the user's line of sight is blocked by the fingers used to hold the pen holder, causing the user to be unable to look directly at the writing area. In order to be able to see clearly, the user will change the correct writing posture and replace it ...

AI Technical Summary

Problems solved by technology

The coaxial pen has the following defects in the process of use: (1) because of the gravity, when the coaxial pen is used for writing, the human hand needs to hold it hard, which is easy to cause soreness and fatigue in the arm; (2) the coaxial pen is easy to As a result, the user's line of sight is blocked by the fingers used to hold the pen holder, causing the user to be unable to look directly at the writing area. In order to be able to see clearly, the user will change the correct writing posture and replace it with a bad posture. If things go on like this, the user The physical health of people will be greatly affected, especially for young children who are in the development period, bad writing posture will seriously affect their normal development

[0004] (1) The different-axis part is a fixed structure, that is, the shape and length of the different-axis part are fixed, so that the writing angle of the whole pen remains unchanged. However, different people's hand shapes and writing habits will be different, so this kind of different-axis pen Unable to meet the needs of people with various writing hand types and writing habits, the adaptability is limited

[0005] (2) The inheritance of writing habits when the coaxial pen is transformed into a non-coaxial pen is not considered

As we all know, the formation of a habit is a long-term accumulation of ideas and practices. Therefore, it is difficult for people to change this writing habit and adapt to other writing methods in a short period of time. When using a different-axis pen, the user will feel very uncomfortable, and feel that using it will hinder the writing operation, so the user is easy to give up using it halfway, so that it is impossible to realize the wide use and promotion of this different-axis pen

[0006] (3) This kind of off-axis pen is curved as a whole, and the built-in refill is a curved shape that matches it. Therefore, this kind of refill must be specially manufactured, so that it cannot be easily purchased in the market, resulting in the off-axis pen It is easy to discard after one-time use, resulting in waste, but if ordinary refills are used instead, there will be a squeezing force on the refill at the different axis, which will cause the refill to cut off water and affect the fluency of writing
