Therefore, students' writing skills are increasingly valued by parents and teachers. With the development of science and technology, more and more people choose intelligent calligraphy practice devices, such as smart pens, which greatly improves the efficiency of calligraphy practice. However, the end of the smart pen is often equipped with many electronic components such as batteries, causing the center of gravity of the smart pen to be biased upward, which is very difficult for younger students to hold. In response to the above technical problems, the present application provides a smart calligraphy practice pen with adjustable pen length. Utility Model Content
[0003] In order to adjust the pen shaft length of the calligraphy practice pen, thereby lowering the center of gravity of the pen shaft according to needs to improve the student's grip comfort, the present application provides an adjustable smart calligraphy practice pen.
[0004] The above-mentioned invention objectives of this application are achieved through the following technical solutions:
[0005] An adjustable smart calligraphy practice pen comprises a first pen holder, a second pen holder and a pen tip, wherein the pen tip is fixedly arranged at one end of the first pen holder, one end of the first pen holder away from the pen tip is open, and the second pen holder extends into the first pen holder through the opening;
[0006] The outer wall of the second pen holder abuts against the inner wall of the first pen holder, and the second pen holder slides back and forth along the direction of the first pen holder;
[0007] Two connecting rods are symmetrically arranged inside the second pen barrel, and the direction of the connecting rods is parallel to the second pen barrel. One end of the connecting rod away from the pen tip is slidably connected to the inner wall of the second pen barrel, and the other end of the connecting rod extends out of the second pen barrel and is engaged with the inner wall of the first pen barrel;
[0008] The end of the connecting rod away from the pen tip is fixedly connected to a pressing block, and the end of the pressing block away from the connecting rod extends out of the first pen holder;

The second pen holder slides back and forth inside the first pen holder and is connected to the first pen holder through a connecting rod, thereby fixing the first and second pen holders. When the pen holder length needs to be adjusted, the button block is pressed to move the connecting rod toward the direction close to the central axis of the second pen holder, thereby separating the connecting rod from the first pen holder. The second pen holder can then be pulled to adjust the pen holder length of the calligraphy pen, thereby lowering the center of gravity of the pen holder as needed;
[0023] 2. The inner wall of the first pen barrel is provided with a plurality of slots arranged in parallel, and the connecting blocks are adapted to fit in the slots. By adjusting the depth of the connecting rod within the first pen barrel, the connecting blocks are engaged with different slots, thereby flexibly adjusting the depth of the second pen barrel extending into the first pen barrel, thereby achieving the purpose of adjusting the pen barrel length of the calligraphy practice pen;
[0024] 3. Press the push block to move the connecting rod toward the center axis of the second pen holder. At this time, the elastic member is squeezed. When the pen holder is adjusted to an appropriate length, release the push block. The rebound force of the elastic member pushes the connecting rod away from the center axis of the second pen holder. The connecting block at the other end of the connecting rod moves synchronously, so that the connecting block automatically engages with the slot to achieve the purpose of fixing the first pen holder to the second pen holder.

[0034] The embodiment of the present application discloses an adjustable smart calligraphy pen. Figure 1-7The calligraphy practice pen includes a first pen holder 1, a second pen holder 2 and a pen tip 3. The pen tip 3 is fixedly arranged at one end of the first pen holder 1. The end of the first pen holder 1 away from the pen tip 3 is open, and the second pen holder 2 extends into the first pen holder 1 through the opening; the outer wall of the second pen holder 2 abuts against the inner wall of the first pen holder 1, and the second pen holder 2 slides back and forth along the direction of the first pen holder 1; two connecting rods 4 are symmetrically arranged inside the second pen holder 2, and the direction of the connecting rod 4 is parallel to the second pen holder 2. The end of the connecting rod 4 away from the pen tip 3 is slidably connected to the inner wall of the second pen holder 2, and the other end of the connecting rod 4 extends out of the second pen holder 2 ; A charging port 6 and a button switch 7 are provided at the end of the second pen shaft 2 away from the first pen shaft 1; a limiting groove 11 is provided on the inner wall of the first pen shaft 1, and a limiting protrusion 12 is fixedly provided on the outer wall of the second pen shaft 2. The limiting protrusion 12 is adapted to fit in the limiting groove 11. When the second pen shaft 2 slides inside the first pen shaft 1, the limiting protrusion 12 slides along the limiting groove 11, causing the second pen shaft 2 to slide in the direction of the limiting groove 11; the cross-sections of the first pen shaft 1 and the second pen shaft 2 along the length direction are both triangular, and the outer walls of the first pen shaft 1 and the second pen shaft 2 are both provided with a number of anti-slip grooves 13 in parallel. The first pen shaft 1 is sleeved on the outer wall of the second pen shaft 2, and the second pen shaft 2 slides back and forth inside the first pen shaft 1 and is clamped with the first pen shaft 1 through the connecting rod 4, so that the first pen shaft 1 and the second pen shaft 2 are fixed. When the pen shaft length needs to be adjusted, the button block 5 is pressed to move the connecting rod 4 toward the direction close to the central axis of the second pen shaft 2, so that the connecting rod 4 is separated from the first pen shaft 1, and the second pen shaft 2 can be pulled to adjust the pen shaft length of the calligraphy pen, thereby lowering the center of gravity of the pen shaft according to needs.
[0035] A plurality of card slots 8 are provided in parallel on the inner wall of the first pen barrel 1. A card block 9 is fixedly provided on the end of the connecting rod 4 extending out of the second pen barrel 2, and the card block 9 is adapted to fit in the card slot 8; a pressing block 5 is fixedly connected to the end of the connecting rod 4 away from the pen tip 3, and the pressing block 5 extends out of the first pen barrel 1 away from the end of the connecting rod 4; an elastic member 10 is fixedly connected to the end of the connecting rod 4 away from the pen tip 3, and the direction of the elastic member 10 is perpendicular to the direction of the second pen barrel 2. The end of the elastic member 10 away from the connecting rod 4 is fixedly connected to the bottom inner wall of the second pen barrel 2. By adjusting the depth of the connecting rod 4 in the first pen barrel 1, the snap-in block 9 is engaged with different slots 8, so that the depth of the second pen barrel 2 extending into the first pen barrel 1 can be flexibly adjusted to achieve the purpose of adjusting the pen barrel length of the calligraphy pen. Pressing the pressing block 5 causes the connecting rod 4 to move toward the direction close to the central axis of the second pen barrel 2. At this time, the elastic member 10 is squeezed. When the pen barrel is adjusted to the appropriate length, the pressing block 5 is released. The rebound force of the elastic member 10 pushes the connecting rod 4 away from the central axis of the second pen barrel 2. The snap-in block 9 at the other end of the connecting rod 4 moves synchronously, so that the snap-in block 9 automatically engages with the slot 8 to achieve the purpose of fixing the first pen barrel 1 and the second pen barrel 2.
[0036] The implementation principle of an adjustable smart calligraphy pen in the embodiment of the present application is as follows: the first pen barrel 1 is sleeved on the outer wall of the second pen barrel 2, and the second pen barrel 2 slides back and forth inside the first pen barrel 1 and is clamped with the first pen barrel 1 through the connecting rod 4, so that the first pen barrel 1 and the second pen barrel 2 are fixed. When the pen barrel length needs to be adjusted, the pressing block 5 is pressed to move the connecting rod 4 in the direction close to the central axis of the second pen barrel 2, so that the connecting rod 4 is separated from the first pen barrel 1, and the second pen barrel 2 can be pulled to achieve the purpose of adjusting the pen barrel length of the calligraphy pen, thereby lowering the center of gravity of the pen barrel according to needs. At this time, the elastic member 10 is squeezed, and when the pen barrel is adjusted to the appropriate length, the pressing block 5 is released. The rebound force of the elastic member 10 pushes the connecting rod 4 in the direction away from the central axis of the second pen barrel 2, and the clamping block 9 at the other end of the connecting rod 4 moves synchronously, so that the clamping block 9 automatically engages with the clamping slot 8 to achieve the purpose of fixing the first pen barrel 1 and the second pen barrel 2.
