[0024] Specifically, during use, the upper end of the pen body 1 is connected to the top cover 2. The top cover 2, as an aesthetic decorative component, is integrated with the pen body 1 to form a whole, making the pen body 1 more aesthetically pleasing during use. A placement block 3 is installed at the front end of the pen body 1, which prevents the pen body 1 from rolling on the table, making the capacitive pen safer. A connecting module 4 is fixedly installed at the lower end of the pen body 1. The connecting module 4 can be threadedly connected to the fixing cover 5. The inside of the fixing cover 5 can hold the pen tip 6. When the fixing cover 5 and the connecting module 4 are connected, the pen tip 6 can be connected to the pen body 1. When the capacitive pen is used, the pen tip contacts the screen, just like a finger, forming an additional capacitance in a local area, which is then recognized by the screen's sensor.
[0025] Reference Figure 4 The connection module 4 includes a fixed cylinder 401, a fixed seat 402 is fixedly installed on the top surface of the fixed cylinder 401, a signal post 404 is fixedly installed on the lower end surface of the fixed seat 402, and a first threaded groove 403 is opened on the outer surface of the fixed seat 402.
[0026] Specifically, the connecting module 4 can connect to the fixing cover 5 during use. The main structure of the connecting module 4 includes a fixing cylinder 401. The inner top surface of the fixing cylinder 401 can fix the fixing seat 402. The lower end of the fixing seat 402 is provided with a signal post 404, which can be connected to the pen barrel 1 through the fixing seat 402. When the pen barrel 1 and the pen tip 6 are connected, the signal post 404 can correct the pen tip 6 so that the pen tip 6 can remain stable during use. The outer surface of the fixing seat 402 is provided with a first threaded groove 403, which allows the fixing cover 5 to be connected to the connecting module 4 through the second threaded groove 503 provided inside.

When the fixing cover 5 and the connecting module 4 are connected, the pen barrel 1 and the pen tip 6 are connected. The main structure of the fixing cover 5 includes a fixing block 501. The pen tip 6 can be placed inside the fixing block 501. A snap-fit cylinder 502 is installed at the upper end of the fixing block 501. The snap-fit cylinder 502 has a second threaded groove 503 inside, so that the snap-fit cylinder 502 can be sleeved on the outer surface of the fixing seat 402 of the connecting module 4, so that the fixing block 501 can be set at the lower end of the connecting module 4.
[0029] Reference Figure 3 The pen tip 6 includes a connecting post 601, a snap-fit block 602 is fixedly provided on the upper end face of the connecting post 601, and an mounting plate 603 is threadedly sleeved on the lower end face of the connecting post 601.

[0030] Specifically, when in use, the pen tip 6 can form an additional capacitor locally, just like a finger, which can be recognized by the screen's sensor, allowing the capacitive pen to function normally. The main structure of the pen tip 6 includes a connecting post 601, the upper end of which is connected to a snap-fit block 602. When the pen tip 6 is installed, the snap-fit block 602 can be snapped into the fixing block 501. When the fixing cover 5 and the connecting module 4 are connected, the signal post 404 inside the connecting module 4 can press the snap-fit block 602, keeping it stable inside the fixing cover 5. The lower end of the connecting post 601 is threaded onto the mounting plate 603, and the lower end of the mounting plate 603 is connected to the conductive rubber disc 604, allowing the conductive rubber disc 604 and the connecting post 601 to be disassembled and replaced if the conductive rubber disc 604 is damaged.
[0031] Working principle: A placement block 3 is installed at the front end of the pen 1. When in use, the placement block 3 prevents the pen 1 from rolling on the table, making the capacitive pen safer. A connection module 4 is fixedly installed at the lower end of the pen 1. When in use, the connection module 4 can connect to the fixing cover 5. The pen tip 6 can be snapped into place inside the fixing cover 5. When the fixing cover 5 and the connection module 4 are connected, the pen 1 and the pen tip 6 are connected. When in use, the pen tip 6 can form an additional capacitor in a local area, just like a finger, which can be recognized by the screen sensor, allowing the capacitive pen to be used normally.
[0032] The main structure of the connecting module 4 includes a fixing cylinder 401. The inner top surface of the fixing cylinder 401 can fix the fixing seat 402. The lower end of the fixing seat 402 is provided with a signal post 404, which can be connected to the pen barrel 1 through the fixing seat 402. When the pen barrel 1 and the pen tip 6 are connected, the signal post 404 can correct the pen tip 6 so that the pen tip 6 can remain stable during use.
