[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-4 The utility model provides the following technical scheme: a handheld device based on star flash wireless communication, including shell 1 and the touch screen 2 of surface embedded installation of shell 1, the four corners of shell 1 are installed with anti-collision block 3, the bottom of anti-collision block 3 is installed with corrugated rubber pad 9, the inside of corrugated rubber pad 9 is installed with spring 10, the lateral wall of shell 1 is connected with line interface 4, the lateral wall of shell 1 is installed with fixed block 5, the inside of fixed block 5 is equipped with two-way threaded rod 6, one end of two-way threaded rod 6 is installed with bearing 7, the surface of two-way threaded rod 6 is connected with clamping block 8.

[0021] In the preferred embodiment, the corrugated rubber pad 9 is made of food-grade rubber material, and the corrugated rubber pad 9 is sleeved on the bottom end of the anti-collision block 3.

[0022] In the preferred embodiment, the other end of the spring 10 is connected to the bottom end of the anti-collision block 3, and the corrugated rubber pad 9 is elastically connected between the spring 10 and the anti-collision block 3.

[0023] In the preferred embodiment, the opposite threads on the surface of the two-way threaded rod 6 are symmetrical, and the two-way threaded rod 6 is rotatably connected between the bearing 7 and the fixed block 5.

[0024] In the preferred embodiment, the clamping block 8 is threadedly reciprocated between the two-way threaded rod 6 and the fixed block 5.

[0025] In the preferred embodiment, the handheld device is based on star flash wireless communication. The star flash technology introduces new technologies such as 5G Polar coding, central scheduling, ultra-short frame, and frequency hopping signal splicing, which improves the sensitivity gain and anti-interference ability. By building differentiated competitiveness, it solves some industry and application pain points that Bluetooth and Wi-Fi cannot solve, and has the following three major features. Moreover, the star flash technology belongs to wireless communication.

[0026] In the handheld device installed star flash module, it is selected to carry out integrated development with Chengdu Yibaitian star flash module, specification E105-BS21.E105-BS21 series module is based on star flash protocol 1.0 version serial port to SLESparkLinkLowEnergy star flash module, with small size, low power consumption, long transmission distance, fast transmission speed, strong anti-interference ability, low delay and other characteristics, working in 2.4GHz frequency band, the maximum radio frequency transmitting power is 6dBm.E105-BS21 series module uses general AT instruction, simple and fast operation.Furthermore, the handheld device of star flash wireless communication is simple and fast in operation, and has stronger anti-interference ability, avoiding the unstable data transmission.

[0027] In addition, the handheld device is composed of a shell 1 and a touch screen 2 and its electric elements known in the art, and the user needs to frequently pick up and place it during use. When placed, one end of the handheld device is first contacted with the desktop by the corrugated rubber pad 9, and then the other end is slowly approached to the desktop under the guidance of the palm until it is completely released, so that the handheld device falls on the desktop in a free-falling manner. In this process, the corrugated rubber pad 9 first contacts and shrinks with the desktop, driving the spring 10 to shrink synchronously, effectively buffering the impact force of the falling. Then, the corrugated rubber pad 9 further absorbs and disperses the impact energy to the anti-collision block 3, significantly improving the use stability and durability of the handheld device.

[0028] Furthermore, the handheld device needs to be connected to a power line during operation. After the power line is plugged into the line interface 4, the user can rotate the bidirectional threaded rod 6 to smoothly rotate in the inner ring of the bearing 7 inside the fixed block 5. With the rotation of the bidirectional threaded rod 6, the clamping blocks 8 approach each other due to the opposite threads on their surfaces, tightly clamping and fixing the power line in the notch of the fixed block 5. This design effectively avoids the situation that the handheld device is disconnected from the line interface 4 due to accidental pulling of the power line during mobile use, further enhancing the practicality and safety of the device.

[0030] Please refer to Figures 1-4 The sidewall of the shell 1 away from the line interface 4 is provided with a handle 11, and the handle 11 is made of metal and has a "Fang" shape.

[0031] In the preferred embodiment, the bottom end of the shell 1 is provided with a suction cup 12, and the suction cup 12 is arranged on the central axis of the bottom end of the shell 1.

[0032] In the embodiments, the handle 11 is ingeniously mounted on the side wall of the shell 1, so that the user can easily carry and move the handheld device through the handle 11, thereby greatly improving the portability thereof. In addition, this design also avoids the user directly holding the shell 1, thereby reducing the adhesion of dust on the surface of the shell 1. In addition, the bottom end of the shell 1 is bolted with the suction cup 12, and this configuration enables the handheld device to be stably fixed on a vertical desktop during use, thereby further enhancing the practicability thereof.
