[0014] The beneficial effects of the present invention are:
[0015] 1. The present invention adopts a combination of a shell, an earpiece, a display screen, and a keypad, so that trainees can better master the use method and technology of the handheld communication device; when conducting simulated communication training, the instructor conducts a simulated call with the trainee through the handheld simulated communication device, and the transmitted information is received by the signal transceiver through the signal transceiver, and is transmitted to the earpiece through the signal processor. The trainee receives the message transmitted by the instructor through the earpiece. After the task is completed, the relevant execution message is transmitted to the signal processor through the sound receiving device, and is sent to the instructor by the signal processor. The instructor analyzes the message and operation process sent back by the trainee, and guides and explains to the trainee, so that the trainee can better master the use method and technology of the handheld communication device; when conducting simulated data transmission training, the instructor communicates with the trainee through the handheld simulated communication device. The relevant data is sent to the handheld analog communication device through a wireless data transmission device, and then transmitted to the controller through a signal transceiver, and the relevant data is displayed on a display screen connected to the controller. The trainees interpret and record the relevant data through the display screen. When the trainees complete the data task and send back the relevant execution data, the trainees input the relevant data into the controller by pressing keys. After the input is completed, it is sent to the instructor through the signal transceiver. The instructor guides and explains the received content and the process of the trainees' operation so that the trainees can better master the use method and technique of the handheld communication device. At the same time, the problem that the display screen is embedded on the side of the shell, so the area of the display screen is small, and the relevant data cannot be displayed completely, which has an adverse effect on the trainees' interpretation and data recording operations.
[0016] 2. The present invention uses a paper roll wheel arranged in the shell to ensure that when the transmitted information is relatively complicated, the trainees can record it with paper, pen, etc., to prevent the occurrence of task failure, extended task time, increased task difficulty, etc. due to forgetting part of the information. The trainees can pull the paper wrapped on the paper roll out of the shell by pulling. Since the paper roll shaft is rotatably arranged in the shell through the first connecting shaft, the paper roll wheel will rotate as the paper is pulled, and the paper will be pulled out of the shell from the paper roll wheel. Then, the relevant information is recorded on the paper with a signature pen. After the trainees complete the relevant information task, the relevant execution information is transmitted to the signal processor via the sound receiving device, and the signal processor sends it to the instructor; this enables the trainees to complete the simulation training faster, improves the training efficiency, and enables the trainees to better master the use method and technology of the handheld communication device, thereby improving the practicality of the present invention.
[0017] 3. The present invention effectively prevents relevant information recorded on the paper from being smeared or rubbed, thereby causing the information to be unrecognizable, by cooperating with the paper collection wheel and the paper roll wheel arranged in the shell. When the trainee pulls the paper wrapped on the paper roll out of the shell by twitching, because the beginning of the paper is wrapped on the paper roll wheel and the end of the paper is wrapped on the winding wheel, when the paper is pulled, the paper roll wheel and the paper collection wheel will rotate at the same time and in opposite directions. Then, relevant information can be recorded on the paper with a signature pen. After the recording is completed, the paper with relevant information recorded can be wound on the paper collection wheel by turning the handle and stored inside the shell. The instructor can provide guidance and explanation through the information sent back by the trainee. The subsequent instructor can also analyze the trainee's operation process through the trainee's handwritten record information and provide further specific guidance so that the trainee can better master the use method and technique of the handheld communication device; thereby improving the training effect and the practicality of the present invention.
[0018] 4. The present invention provides a signature pen at the center of the shell, making it more convenient for students to record relevant data information, solving the problem of wrong or missed related information due to forgetting to bring a signature pen when recording. It also solves the problem that teaching staff cannot analyze students' operation process through students' records, thereby reducing training efficiency and hindering students from mastering the use method and technique of handheld communication devices. It improves the practicality and convenience of the present invention and enables the present invention to better adapt to various training scenarios.
[0019] 5. The present invention combines the layer plate with the magnetic guide rail so that the transfer screen does not need to be connected to the controller and the battery through a line, thereby solving the problem that the transfer screen cannot operate normally due to short circuit or breakage of the line caused by frequent sliding of the transfer screen. When in use, the transfer screen can be pulled out of the shell by pulling the layer plate. At this time, the connector embedded in the layer plate slides in the magnetic guide rail and maintains the connection state with the magnetic guide rail. Since the magnetic guide rail is electrically connected to the controller and the battery, and the connector is electrically connected to the transfer screen, the transfer screen can be electrically connected to the controller, so that the trainee can issue instructions to the controller by pressing keys to display relevant data on the transfer screen. At the same time, the transfer screen can be turned on and off by pressing keys, and the size, color and other formats of the relevant data displayed on the transfer screen can be adjusted, which is convenient for trainees to interpret and record data, so that trainees can better master the use method and technology of the handheld communication device, improve training efficiency, and at the same time improve the practicality of the present invention, reduce the use cost and maintenance cost of the present invention, and extend the service life of the present invention.
[0020] 6. The present invention solves the problem of inconvenient maintenance and replacement of keys after they are worn out by using a keyboard composed of a PCB circuit board and keys. When the keys need to be repaired or replaced, it is only necessary to remove the keys and then snap new keys onto the PCB circuit board, thereby reducing the maintenance cost of the present invention and extending the service life of the present invention.
[0021] 7. The present invention solves the problem of difficulty in replacing paper rolls by means of a through-hole ring and a hatch provided on one side of the shell. When replacing the paper roll, the hatch is opened, and the paper-winding wheel and the paper-collecting wheel are taken out. After the replacement is completed, the paper-winding wheel and the paper-collecting wheel are put back into the shell, and the end of the paper roll is conveniently connected to the paper-collecting wheel, which reduces the operation steps when replacing the paper roll and improves the practicality and convenience of the present invention.
[0022] 8. The present invention solves the problem of complicated operation steps during charging by providing a charging port on the bottom surface of the shell. When charging is needed, the charging cable can be connected to the charging port to complete the charging. Therefore, there is no need to frequently replace the battery, nor is there any need to take the battery out for charging, which reduces the operation steps during charging and improves the practicality and convenience of the present invention.

[0035] The specific working principle is:
[0036] When conducting simulated communication training, the instructor conducts a simulated conversation with the trainee through a handheld simulated communication device. The transmitted information is received by the signal transceiver and transmitted to the earpiece via the signal processor. The trainee receives the message transmitted by the instructor through the earpiece. When the transmitted message is more complicated, the trainee can pull the paper wrapped on the paper roll out of the shell by pulling. Because the beginning of the paper is wrapped on the paper roll wheel and the end of the paper is wrapped on the winding wheel, the paper roll wheel and the winding wheel will rotate at the same time when the paper is pulled, and rotate in opposite directions. Then take out the signature pen from the top surface of the shell and record the relevant information on the paper to prevent the failure of the task, extend the task time, increase the difficulty of the task, etc. due to forgetting part of the information. After the recording is completed, the paper with the relevant information recorded can be wound around the paper collection wheel by turning the handle, which can effectively prevent the relevant information recorded on the paper from being smeared or rubbed, thereby causing the information to be unrecognizable. After the paper is wound around the paper collection wheel, the signature pen is put back into the shell, and the relevant execution information is transmitted to the signal processor through the sound receiving device, and the signal processor sends it to the instructor; the instructor analyzes the information sent back by the trainee, and guides and explains to the trainee. The subsequent instructor can also analyze the trainee's operation process through the trainee's handwritten record information, and provide further specific guidance to the trainee to correct the errors in the trainee's operation, so that the trainee can better master the use method and technology of the handheld communication device;
[0037] When conducting simulated data transmission training, the instructor sends the relevant data to the handheld simulated communication device through the wireless data transmission device, and then transmits it to the controller via the signal transceiver, and displays the relevant data on the display screen connected to the controller. The trainees interpret and record the relevant data through the display screen. When the transmitted data is large, because the display screen is embedded in the side of the shell, the display area of the display screen is small, and the relevant data cannot be displayed completely, which has an adverse effect on the trainees' interpretation and data recording operations. At this time, the adapter screen can be pulled out of the shell by pulling the layer plate. At this time, the connector embedded in the layer plate slides in the magnetic guide rail and remains connected to the magnetic guide rail. Because the magnetic guide rail is electrically connected to the controller and the battery, and the connector is electrically connected to the adapter screen, the adapter screen can be electrically connected to the controller. The trainees can issue instructions to the controller by pressing keys, and display the relevant data on the transfer screen. At the same time, they can also control the opening and closing of the transfer screen by pressing keys, and adjust the size, color and other formats of the relevant data on the transfer screen, so that the trainees can interpret and record the data conveniently. They can also pull out the paper for refining and summarizing the records (the principle of pulling out the paper here is the same as the principle of pulling the paper mentioned above, and will not be elaborated here); when the trainees complete the data task and return the relevant execution data, the trainees input the relevant data into the controller by pressing keys, and then send it to the instructor's wireless data transmission device via the signal transceiver. The instructor analyzes the received content and the trainees' operation process, and guides and explains to the trainees, so that the trainees can better master the use methods and techniques of the handheld communication device.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
