Description

A retractable fountain pen

technical field

The utility model belongs to the field of retractable pens, in particular to a retractable water pen.

Background technique

At present, almost all pens have a fixed length, and the innovation of many pens is to make a fuss about the appearance, and the actual function of the pen has not changed. A fixed-length pen cannot adapt to hands of different sizes, so it is necessary to design a fountain pen suitable for adjusting the length of the refill during writing. Moreover, people who practice calligraphy often need to imitate the copybook. The same character needs to be practiced many times to gain something. It is impossible to effectively grasp whether the strokes are standardized. Therefore, it is necessary to save time and remind the strokes in a timely manner. fountain pen.

Contents of the invention

The technical problem to be solved by the utility model is to provide a retractable water pen, which can adjust the length of the pen according to the size of the hand, and can effectively and timely correct bad habits when writing, so as to achieve the purpose of standard writing.

The technical solution adopted by the utility model to solve the technical problem is: provide a retractable fountain pen, including a nib, a grip, a pen holder and a tail cover, the nib and one end of the pen are connected through the grip, so The other end of the pen holder is nested with the casing structure of the tail sleeve part, the grip part is embedded with a chip and a reminder light, and a photoelectric sensor is embedded on the tip of the pen, and the chip controls the connection between the photoelectric sensor and the cue light.

There is a spiral connection between the pen tip and the grip part.

There is a spiral connection between the penholder and the gripping part.

The pen shaft is nested in the tail sleeve part in the axial direction in the form of a piston.

Beneficial effect

The utility model has the following advantages and positive effects:

The tail cover part of the utility model is connected with the pen holder part through a piston structure, and the tail cover can move along the axial direction of the pen holder, so that the length of the pen can be adjusted to adapt to hands of different sizes, and the implementation method is flexible; The photoelectric sensor is used to scan the movement track of the pen tip when writing, and transmit the information to the chip to judge whether it is standardized, so as to activate the reminder light to remind the function, effectively and timely correct bad habits when writing, and achieve the purpose of standard writing.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

As shown in Figure 1, a retractable fountain pen includes a nib 1, a grip 2, a pen holder 3 and a tail cover 4, the nib 1 is connected to one end of the pen holder 3 through a grip 2, and the pen holder The other end of 3 is nested with the sleeve structure of the tail sleeve part 4, the chip 5 and the reminder light 6 are embedded in the grip part 2, the photoelectric sensor 7 is embedded in the end surface of the nib 1, and the chip 5 controls and connects the photoelectric sensor 7 and the prompt lamp 6.

The nib 1 and the handle 2 are connected by a screw.

The penholder 3 and the handle 2 are connected by a screw.

The pen holder 3 is nested in the tail sleeve part 4 in the axial direction in the form of a piston.

Example

The tail cover part of the utility model is connected with the pen holder part through a casing structure, and the tail cover can carry out piston movement along the axial direction of the pen holder, so that the length of the pen can be adjusted to adapt to hands of different sizes, and the implementation method is flexible.

It is worth mentioning that the photoelectric sensor on the surface of the pen tip of the utility model is used to scan the movement track of the pen tip when writing, and transmit the information to the chip. The chip compares the scanned information with the internal storage information to judge the practice. Whether the writing is standardized, if it is not standardized, the chip will start the reminder light to remind the function, effectively and timely correct the bad habits when writing, and achieve the purpose of writing specification.
