Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] See also Figure 1-4 As shown, a multifunctional dot matrix digital pen comprises a pen holder 1, a pen core 3 and a mounting head 12, wherein the pen core 3 is mounted in the pen holder 1 and fixed by the mounting head 12;

[0030] It also includes a retraction mechanism, a protective device and an elastic member 13;

[0031] The retracting mechanism comprises a connecting column 5, the connecting column 5 is fixedly connected in the pen holder 1, a through hole 20 is opened on the surface of the connecting column 5, the through hole 20 passes through the side wall of the pen holder 1, and a sliding shaft 6 is slidably connected in the through hole 20 via a spring;

[0032] The surface of the refill 3 is fixedly sleeved with a fixed shaft 7, the fixed shaft 7 is slidably installed in the connecting column 5, the surface of the fixed shaft 7 is provided with a notch 4, one side wall of the notch 4 is an inclined surface, and the surface of the sliding shaft 6 is provided with an inclined angle 21;

[0033] The elastic member 13 is movably mounted on the surface of the pen core 3, with one end being in contact with the fixed shaft 7 and the other end being in contact with the mounting head 12;

[0034] During operation, the pen core 3 is first installed in the pen barrel 1, and then the elastic member 13 is sleeved on the surface of the pen core 3, and then the mounting head 12 is installed on the surface of the pen barrel 1. Then, the pen barrel 1 is held and the sliding shaft 6 is pressed at the same time, so that the sliding shaft 6 moves in the direction of the fixed shaft 7. At the same time, the inclined surface on the surface of the fixed shaft 7 will squeeze the notch 4, so that the fixed shaft 7 moves in the connecting column 5, and at the same time, the pen tip will be extended so that it can be used for writing. Because the dot matrix is ​​composed of very small dots, and these dots constitute coordinate parameter information through specific arrangement rules, the digital pen can accurately record the coordinates of the location of the writing handwriting during the writing process. During the handwriting process using the dot matrix digital pen, the input information is collected and digitally processed in real time by the dot matrix digital pen. When the pen barrel 1 is placed on the desktop after use, the spring drives the sliding shaft 6 to reset, so that the elastic member 13 drives the pen core 3 to automatically retract into the pen barrel 1, so as to avoid the pen tip being damaged when the pen barrel 1 falls from the desktop.

[0035] The pen barrel 1 has an arc groove 2 on its surface, two of which are provided, and the angle between a pair of the arc grooves 2 is 60°. The pressing piece 19 is arc-shaped corresponding to the arc groove 2, and a circular arc angle is provided on the surface of the fixed shaft 7. When working, the design of the arc groove 2 can improve the comfort of hand holding, and the pressure between the sliding shaft 6 and the fingers of the staff can be increased by the pressing piece 19 to avoid discomfort in the fingers of the staff over time.

[0036] The end of the sliding shaft 6 away from the fixed shaft 7 is fixedly connected with a pressing plate 19, and a non-slip pad is bonded to the surface of the pressing plate 19. Two connecting columns 5 are provided, and a stack of the connecting columns is symmetrically distributed with respect to the central axis of the pen shaft 1. A groove 22 is provided on the surface of the arc groove 2. When working, the design of the two sliding shafts 6 allows two fingers to exert force at the same time when pressing, so that the fixing effect of the pen core 3 is better, and the stability during writing is improved. The flatness of the inner wall of the arc groove 2 can be improved by the groove 22.

[0037] The protective device comprises a protective shell 11, which is arranged on the surface of the pen holder 1, a rubber block 14 is fixedly connected to the inner wall of the protective shell 11, a cleaning structure is arranged in the protective shell 11, and the cleaning structure comprises a top block 10, which is installed on the surface of the protective shell 11 through a thread, a mounting groove 18 is opened on the surface of the top block 10, a sponge block 17 is arranged in the mounting groove 18, a main magnetic block 15 is fixedly connected in the mounting groove 18, a secondary magnetic block 16 is fixedly connected to one side of the sponge block 17, and the main magnetic block 15 is fixedly connected to the auxiliary magnetic block 16. The opposite poles attract each other with the auxiliary magnetic block 16; during operation, when the protective shell 11 is installed on the surface of the pen barrel 1, the rubber block 14 on the inner wall of the protective shell 11 will squeeze the pressing piece 19, so that the pen core 3 extends out and is inserted into the sponge block 17, and then when the rubber block 14 is separated from the pressing piece 19, the pen tip is retracted, and the sponge block 17 is used to clean the pen tip to avoid the ink accumulated at the position of the pen tip affecting the writing during use. The sponge block 17 installed by magnetic attraction can be easily replaced after a long period of use by unscrewing the top block 10 out of the protective shell 11.

[0038] Embodiment 2

[0039] See also Figure 5 As shown, compared with Example 1, as another implementation of the utility model, the inner wall of the protective shell 11 is fixedly connected with a sealing ring 23, and the sealing ring 23 is made of rubber. The sealing ring 23 fits the outer wall of the mounting head 12; when working, by installing the protective shell 11 on the surface of the pen body 1, the sealing ring 23 will fit the surface of the mounting head 12, and the inside of the mounting head 12 will be sealed to avoid the dry tip of the pen.

[0040] The working principle is to install the refill 3 in the pen holder 1 first, then sleeve the elastic member 13 on the surface of the refill 3, and then install the mounting head 12 on the surface of the pen holder 1. Then, by holding the pen holder 1 and pressing the sliding shaft 6, the sliding shaft 6 moves toward the fixed shaft 7. At the same time, the inclined surface of the fixed shaft 7 squeezes the notch 4, so that the fixed shaft 7 moves in the connecting column 5, and at the same time, the pen tip is extended so that writing can be performed. Because the dot matrix is ​​composed of very small dots, and these dots form coordinate parameter information through specific arrangement rules, the digital pen can be easily moved during writing. The coordinates of the position of the handwriting can be accurately recorded. During the handwriting process using the dot matrix digital pen, the input information is collected and digitally processed in real time by the dot matrix digital pen. When the pen holder 1 is placed on the desktop after use, the spring drives the slide shaft 6 to reset, so that the elastic member 13 drives the pen core 3 to automatically retract into the pen holder 1, thereby preventing the pen tip from being damaged when the pen holder 1 falls from the desktop. The design of the arc groove 2 can improve the comfort of the hand when holding it, and the pressure between the slide shaft 6 and the fingers of the staff can be increased by the pressing sheet 19, thereby preventing the fingers of the staff from feeling uncomfortable after a long time.

[0041] The design of the two sliding shafts 6 allows two fingers to exert force at the same time when pressing, so that the pen core 3 is better fixed and the stability during writing is improved. The groove 22 can improve the flatness of the inner wall of the arc groove 2. When the protective shell 11 is installed on the surface of the pen barrel 1, the rubber block 14 on the inner wall of the protective shell 11 will squeeze the pressing sheet 19, so that the pen core 3 extends out and is inserted into the sponge block 17. Then, when the rubber block 14 is separated from the pressing sheet 19, the pen tip is retracted and the pen tip is cleaned by the sponge block 17 to prevent the ink accumulated at the pen tip position from affecting the writing during use. The sponge block 17 installed by magnetic attraction can be easily replaced by unscrewing the top block 10 out of the protective shell 11 after a long period of use. When the protective shell 11 is installed on the surface of the pen barrel 1, the sealing ring 23 will fit on the surface of the mounting head 12 to seal the inside of the mounting head 12 to prevent the pen tip from drying out.
