[0032] In the embodiment, the shaft hole part 2 includes: upper shaft hole 21, middle shaft hole 22 and lower shaft hole 23 sequentially set up in the middle part of tip body 1 from top to bottom.
[0033] It should be noted that the inner diameter of the upper shaft hole 21 is gradually larger than the inner diameters of the middle shaft hole 22 and the lower shaft hole 23, and the upper shaft hole 21, the middle shaft hole 22 and the lower shaft hole 23 are coaxially arranged with the pen head body 1 and the pen core component 3; through the arrangement of the upper shaft hole 21, the bottom end of the pen barrel of the stylus can be docked, through the arrangement of the lower shaft hole 23, the top end of the pen core component 3 can be docked, and through the arrangement of the middle shaft hole 22, the upper shaft hole 21 and the lower shaft hole 23 can be communicated to ensure the docking of the pen barrel of the stylus and the pen core component 3, realize stable transmission of electric charge, and since the inner diameters of the upper shaft hole 21, the middle shaft hole 22 and the lower shaft hole 23 gradually decrease, not only the structural strength of the pen head body 1 is enhanced, but also spaces are provided for the step-by-step fixing of the stylus and the pen core component 3.

[0037] As shown in Figure 4 The present application provides a stylus comprising the pen head assembly according to any one of the preceding embodiments.
[0038] In the embodiment, the side of the pen barrel near the bottom end is connected with the pen head assembly through the shaft hole component 2, and the bottom end of the pen barrel is provided with a contact component 4. The contact component 4 comprises: an expansion slot 41 opened at the bottom end of the pen barrel, a contact pin 42 sleeved on the inner side of the expansion slot 41, and a reset spring 43 fixed between the top end of the contact pin 42 and the inner side of the expansion slot 41. The contact pin 42 is in transition fit with the expansion slot 41, and the bottom end of the contact pin 42 is in contact with the top end of the pen core sleeve 31.
[0039] It should be noted that the pen barrel of the stylus is connected with the pen head assembly through the shaft hole component 2, which can realize detachable connection of the pen barrel and the pen head assembly. When the pen barrel of the stylus is detachably connected to the top end of the pen head body 1, the reset spring 43 and the contact pin 42 in the expansion slot 41 can form an extendable effect, and a variable allowance is formed when the contact pin 42 at the bottom of the pen barrel is in contact with the contact block 311. Thus, when the length of the pen core sleeve 31 in the pen core component 3 fluctuates due to brand or model differences, the longer or shorter pen core sleeve 31 can still be in good contact with the contact pin 42, achieving better adaptation, so as to ensure stable electrical signal transmission and avoid the problem of difficult installation of the pen head assembly and the pen barrel, thereby significantly improving the universality and compatibility.
[0040] In use, the pen barrel of the stylus is detachably connected with the pen head assembly through the shaft hole component 2. In the pen head assembly, the pen head body 1 serves as a support structure, and the shaft hole component 2 opened in the pen head body 1 is used to install and fix the pen core component 3. The pen core component 3 is composed of a pen core sleeve 31 plated with gold on a copper surface, a buffer groove 32, a conductive pin 33, and a damping spring 34. When the stylus contacts and presses the screen, the conductive pin 33 is pressed and deepens into the buffer groove 32. Since the side of the conductive pin 33 is in transition fit with the inner side of the buffer groove 32, the stable movement of the conductive pin 33 in the buffer groove 32 is ensured. At this time, the damping spring 34 plays a buffering role, disperses the impact force on the screen during writing, reduces sudden and strong friction, and makes the writing process smoother and quieter. At the same time, the arc structure at the bottom end of the conductive pin 33 uniformly bears force, reduces single-point pressure, reduces friction noise, and reduces physical wear on the screen. The contact component 4 at the bottom end of the pen barrel is composed of an expansion slot 41, a contact pin 42, and a reset spring 43, forming an extendable effect, ensuring good contact between the contact pin 42 and the contact block 311 of the pen core sleeve 31, and realizing stable electrical signal transmission. Not only does it improve the writing comfort and quietness of the stylus, but also enhances its universality and compatibility, making it suitable for different brands and models of touch devices.

[0042] As Figure 5As shown, the embodiment is basically the same as embodiment 1, the difference is that the side of the connecting block 312 is screwed with the inner side of the lower shaft hole 23.
[0043] It should be noted that when connecting and installing the refill component 3 to the bottom end of the pen head body 1, by screwing the connecting block 312 in the refill sleeve 31 into the inner side of the lower shaft hole 23, the refill sleeve 31 can be screwed with the lower shaft hole 23, and the connection and installation of the refill component 3 can be completed, not only ensuring the firm installation of the refill component 3 in the pen head body 1, but also providing a convenient disassembly method, at the same time, the tightness of the screw connection also effectively prevents external factors such as dust and moisture from invading the inside of the pen head, and protects the electrical performance and service life of the components.
