[0030] See also Figures 1 to 3 The stylus pen disclosed in the utility model comprises a conductive pen holder 1 and a pen cap 2 detachably connected to the pen holder 1. The pen cap 2 comprises a first stylus pen head 20, a main body 21 for fixing the first stylus pen head 20, and a conductive component 22. When the pen cap 2 is buckled with the pen holder 1, the conductive component 22 is electrically connected to the pen holder 1. The pen cap 2 also comprises an elastic body electrically connecting the first stylus pen head 20 and the conductive component 22.

[0031] The stylus of the utility model sets the first stylus tip 20 on the pen cap 2, sets an elastic body between the conductive component 22 and the first stylus tip 20, and electrically connects the conductive component 22 and the first stylus tip 20 through the elastic body. In this way, when the stylus is vibrated or impacted, the elastic body balances the work done by the external force through elastic deformation, avoids the separation of the conductive component 22 and the first stylus tip 20, and ensures good electrical contact between the first stylus tip 20 and the pen holder 1. At the same time, the elastic member has a simple structure, can reduce the weight of the stylus, is easy to carry, and has a better feel when used.

[0032] In this embodiment, one end of the elastic body abuts against the first stylus pen head 20, and the other end abuts against the conductive component 22. Since a predetermined structure does not need to be separately set for the abutment, it is only necessary to compress the first elastic body between the first stylus pen head 20 and the conductive component 22, so the product structure is simplified, easy to produce, and easy to assemble, which can reduce production costs and improve production efficiency.

[0033] In this embodiment, the elastic body is a spring 23, and the spring 23 is a compression spring. An installation position for assembling the spring 23 is provided in the main body 21.

[0034] Of course, in other embodiments of the present application, the elastomer may also be a column with elastic deformation capability, such as a conductive silicone column or a conductive rubber column.

[0035] In addition, the elastic body can also be fixedly connected to the first stylus tip 20 and the conductive component 22 at both ends, and arranged between the two in an extended state to provide elastic force pulling toward the center of the two, such as a tension spring. This structure can achieve the effect of preventing the first stylus tip 20 and the conductive component 22 from separating.

[0036] Specifically, the main body 21 is a hollow structure, and the main body 21 is a plastic part. The main body 21 includes a first end and a second end opposite to the first end, the first stylus tip 20 is arranged at the first end, the conductive component 22 is accommodated in the second end, and the second end is provided with an opening 210, and is connected to the pen holder 1 through the opening 210. A cavity for assembling an elastic member is provided in the main body 21, and the cavity serves as a mounting position for the spring 23.

[0037] The first stylus tip 20 includes a first stylus core 201 and a conductive sheath 202 sleeved on the first stylus core 201 , wherein one end of the conductive sheath for contacting the mobile terminal screen is a curved surface, and the first stylus core 201 is electrically connected to the spring 23 .

[0038] like Figure 2 and Figure 4As shown, a mounting hole 211 is provided at the first end of the main body 21, and a conductive rod 2010 is provided at one end of the first stylus core 201, which can be inserted into the mounting hole 211, and the conductive rod 2010 is threadedly connected with the mounting hole 211. The mounting hole 211 is connected to a cavity for assembling an elastic member, and a blocking portion 2011 is provided on the conductive rod 2010. When the conductive rod 2010 is screwed into the mounting hole 211, the spring 23 is sleeved on the conductive rod 2010 and abuts against the blocking portion 2011.

[0039] The conductive component 22 includes a conductive seat 220 for electrically connecting to the elastomer, a support body 221 for fixing the conductive seat 220, and a conductive sleeve 222 fixedly connected to the support body 221. The support body 221 is a plastic part, the conductive seat 220 is fixed to one end of the support body 221 facing the elastomer, the conductive sleeve 222 and the conductive seat 220 are both metal parts, the conductive sleeve 222 is sleeved on the support body 221 and fixedly connected thereto, and the end of the conductive sleeve 222 facing the elastomer is fixedly connected and electrically connected to the conductive seat 220. The conductive sleeve 222 and the conductive seat 220 can be threaded, plug-in, or snap-in, as long as the two are fixedly connected and electrically contacted, and this application does not make any specific restrictions.

[0040] like Figure 2 and Figure 3 As shown, the end of the conductive seat 220 facing the elastic body is provided with a first assembly part for fixing the elastic body, and the end of the conductive seat 220 facing away from the elastic body is threadedly connected with the support body 221. The first assembly part is a screw hole 2200 adapted to the spring 23, and the screw hole 2200 ensures good electrical contact between the spring 23 and the conductive seat 220, and prevents the spring 23 from being separated from the conductive seat 220.

[0041] There are many types of stylus tips for existing styluses, mainly including curved pen tips and flat pen tips. The curved pen tips have the advantages of smooth sliding and wear resistance when writing on the terminal screen due to their small contact area, but they lack precision; the flat pen tips have high precision due to their large contact surface with the screen, but they have large friction resistance, are easy to break and fall off, and have a short lifespan. Therefore, people often need to carry multiple styluses with them. When high-precision interaction is required, flat pen tips are used, but when the interaction precision requirements are low, curved pen tips are used to meet the needs of daily work and life.

[0042] However, multiple styluses take up space and are inconvenient to carry and difficult to find and use, which brings great inconvenience to daily use.

[0043] In order to solve this technical problem, in this embodiment, a second stylus tip 3 which can be inserted into the conductive sleeve 222 and electrically connected thereto is provided at the front end of the pen shaft 1 , and the second stylus tip 3 is electrically connected to the pen shaft 1 .

[0044] Among them, Figure 2 , Figure 3 and Figure 5 As shown, the second stylus tip 3 includes a second refill 30 fixed to the pen body 1, and a pen holder 31 for fixing the second refill 30. The pen holder 31 and the second refill 30 are both conductors. A conductive plate 300 for contacting the terminal screen is provided at the end of the second refill 30, and the surface of the conductive plate 300 is a plane. A conductive ring 32 for electrically connecting the pen body 1 and the second refill 30 is also provided at the head end of the pen body 1, and the conductive ring 32 is accommodated in the pen holder 31. A conductive column 301 that can be inserted into the conductive ring 32 and electrically connected to it is provided at the end of the second refill 30 that is away from the conductive plate 300, and the outer surface of the conductive ring 32 is in contact with the inner cavity of the pen holder 31, so that the electrical connection between the second refill 30 and the pen holder 31 is achieved through the conductive ring 32.

[0045] The pen holder 31 is connected to the pen barrel 1 by plugging or threading to achieve fixed connection and electrical connection between the two. A connector 10 for fixing the pen holder 31 is also provided inside the pen barrel 1. The connector 10 is a plastic part, one end of which is predetermined inside the pen barrel 1, and the other end can be inserted into the pen holder 31, so that the connection between the pen holder 31 and the pen barrel 1 is more secure, and the conductive ring 32 is prevented from moving, and at the same time, it plays a supporting role for the connection of the pen barrel 1. A waterproof plug 11 is also provided at the tail end of the pen barrel 1 to play a role in dust and water prevention.

[0046] In this way, by setting a first touch pen head 20 on the pen cap 2 and a second touch pen head 3 at the head end of the pen shaft 1, a structure with multiple pen heads of the same touch pen is realized to meet the needs of various touch operations. Only one touch pen of the utility model needs to be carried to cope with various scenes, which is easy to carry and meets the needs of multiple scenes.

[0047] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention.
