A reserved groove 214 is provided on the bottom outer frame of the communication terminal body 1.

[0029] The top of the limiting rod 202 is provided with a protruding ring to ensure that the limiting rod 202 and the connecting rod 203 do not separate, thus playing a limiting role. The connecting rod 203 is made of elastic material and is designed to be slightly larger than the truncated pyramid hole 201. When the connecting rod 203 is inserted into the truncated pyramid hole 201, it will not loosen. By adjusting the tightness of the nut 205, the protective shell 206 can be flipped to a suitable angle behind the communication terminal body 1 and fixed, serving as a temporary support. Rubber burrs that increase friction can be provided on the bottom of the protective shell 206 and the communication terminal body 1 to increase the stability of the support. The left end of the connector 209 is provided with a protruding ring to ensure that it will not fall off from the reserved hole 208. The duckbill rubber seat 213 is a model that is slightly larger than the heat dissipation hole 211 to increase the friction generated when it is fitted onto the inner wall of the heat dissipation hole 211, thus preventing it from falling off.

[0030] Specifically, the rotation restriction of the protective shell 206 can be released by loosening the nut 205, and the protective shell 206 can be rotated to a position parallel to the communication terminal body 1. The connecting rod 203 is pushed down to be inserted into the truncated hole 201. At the same time, the lower end of the protective shell 206 is inserted into the reserved slot 214 to complete the tight closure, effectively preventing dust and water stains from entering the screen. The charging port 207 can be opened and closed through the set connector 209 and protective plug 210 to ensure the dustproof and waterproof function of the charging port 207 when not in use. The combination of the dustproof cloth 212 and the duckbill rubber seat 213 ensures that the heat generated by the heat dissipation hole 211 is dissipated while preventing external dust and water from entering.

[0031] Example 2:

[0032] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 7 - Appendix Figure 11 Furthermore, based on Embodiment 1, a portable mechanism 3 is provided behind the reserved slot 214. The portable mechanism 3 includes a pen slot 301 and a mounting base 305. The pen slot 301 is located on the lower left side of the communication terminal body 1, and a bolt 302 is threaded to its left end. A pen tip sleeve slot 303 is located on the lower right side of the communication terminal body 1 at the same level as the pen slot 301. A rubber plug 304 is inserted into the inner wall of the right end of the pen tip sleeve slot 303. The back of the communication terminal body 1 is located on both sides near the center. Each component is fixedly connected to a mounting base 305. A gripping module 306 is inserted into the groove of the mounting base 305. The mounting base 305 has cross grooves 311 on both the upper and lower sides of the end near the middle of the communication terminal body 1. Multiple sets of first springs 308 are fixedly connected to the inner wall of the cross grooves 311. A release block 307 is fixedly connected to the other end of the multiple sets of first springs 308. A second spring 309 is fixedly connected to the opening on the front of the gripping module 306. A limit member 310 is fixedly connected to the other end of the second spring 309.

[0033] The left end of bolt 302 is provided with anti-slip threads to facilitate the storage and retrieval of the matching stylus. The internal size of the pen slot 301 should be reasonably designed and made of elastic material to prevent the stylus from being bumped or damaged. The pen tip sleeve slot 303 can store small parts, such as pen tip sleeves and replacement screws, to improve the adaptability of the communication terminal. After the holding module 306 is inserted into the mounting base 305, the limiting member 310 abuts against the release block 307 to facilitate disassembly when pressing the release block 307. The shape of the holding module 306 can be varied to not only adapt to different users' hand sizes and improve user comfort, but also to be designed to facilitate horizontal or vertical holding according to the usage scenario, meeting different user needs.

[0034] Specifically, the matching stylus can be easily accessed by tightening the bolt 302, and the stylus tip sleeve can be easily replaced by pulling out and inserting the rubber plug 304 as needed, making the use smoother. Pressing the limiting piece 310, the appropriate holding module 306 is inserted into the mounting base 305 from the side away from the communication terminal body 1.

[0035] Working principle of this utility model: This utility model is a dustproof and waterproof wireless communication terminal. When using this product, first pull out the connecting rod 203, loosen the nut 205, and flip the protective shell 206. The protective shell 206 can be fixed at a suitable angle by tightening the nut 205. When the wireless communication terminal needs to be used on a table, the protective shell 206 can act as a temporary support. If held by hand, it can also prevent the protective shell 206 from becoming unstable due to rotation. After use, the protective shell 206 is closed by reversing the steps to complete the protection of the communication terminal screen. During non-charging time, the protective plug 210 covers the charging port 207 to protect it. When the product dissipates heat at the heat dissipation hole 211, the heat flows through the dustproof cloth 21. 2. The duckbill rubber seat 213 is opened to allow the product to dissipate heat normally. After heat dissipation is complete, the duckbill rubber seat 213 closes to prevent the entry of external water and dust, thus achieving a protective function. When the stylus needs to be used, the stylus can be taken out by turning the bolt 302. Different stylus tip sleeves or other small parts can be replaced by pulling out the rubber plug 304. When the communication terminal needs to be held, the appropriate holding module 306 is selected according to the horizontal or vertical holding method and the size of the individual's hand. The limiting piece 310 is pressed and inserted into the mounting base 305. After hearing a "click", the installation is completed and the holding operation is performed. After holding is finished, the release block 307 is pressed and the holding module 306 is pulled out to complete its disassembly.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
