[0023] A display screen 4 and a speaker 14 are fixedly connected to the left side and the right side of the explanation device body 1 respectively. The display screen 4 is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. The model of the display screen 4 is MEG342CQL-OLED. The speaker 14 is a device that converts electrical signal energy into sound energy and can radiate sound energy to a limited space or outdoor space. The model of the speaker 14 is MG20NS1. The display screen 4 and the speaker 14 are both electrically connected to the explanation device body 1 through wires. By using the display screen 4 and the speaker 14 in conjunction with the explanation device body 1, the knowledge of the study tour can be conveniently displayed through the display screen 4, and the external microphone of the speaker 14 can be used to facilitate the user to use the microphone and the speaker 14 to transmit the knowledge of the study tour in sound.

[0024] A protective ring 5 is fixedly connected to the outer surface of the display screen 4, and the right side of the protective ring 5 is fixedly connected to the left side of the explanation device body 1. The protective ring 5 can be used to stably connect the display screen 4 to the explanation device body 1 and protect the display screen 4.

[0025] Two lifting columns 2 are fixedly connected to the upper surface of the explanation device body 1, and a lifting belt 3 is movably hinged at the top of the two lifting columns 2. By manually pulling the lifting belt 3, the two lifting columns 2 can be used to pull the explanation device body 1, thereby facilitating the lifting and use of the explanation device body 1.

[0026] A reinforcement ring 15 is fixedly connected to the outer surface of the connecting threaded barrel 16, and the upper surface of the reinforcement ring 15 is fixedly connected to the bottom surface of the explanation device body 1. The reinforcement ring 15 is fixed at the connection between the connecting threaded barrel 16 and the explanation device body 1, thereby stably improving the connection stability between the connecting threaded barrel 16 and the explanation device body 1.

[0027] The outer surface of the connecting stud 17 is threadedly connected with a stabilizing nut 18, and the upper surface of the stabilizing nut 18 is in contact with the bottom surface of the connecting threaded barrel 16.

Through the cooperation of the first connecting block 20 and the second connecting block 21, the supporting structure can be hinged at one end of the connecting rod 19. Since the first connecting block 20 and the second connecting block 21 are hinged too tightly, the supporting structure can be stably supported and can also be folded.

[0029] The bottom surface of each second connecting block 21 is fixedly connected with a supporting column 12, and the bottom end of each supporting column 12 is fixedly connected with a supporting plate 13. By fixing the supporting column 12 on the bottom surface of the second connecting block 21, the supporting column 12 and the supporting plate 13 can form a supporting structure, thereby facilitating the support of the main body 1 of the explanation device.

[0030] The working principle of the utility model is as follows: when in use, firstly, the explanation device body 1, the display screen 4 and the speaker 14 are all connected to the internal battery power supply. When it is necessary to carry and use the portable explanation device to explain the knowledge of the study tour, the portable explanation device is first placed in the required position manually, and the portable shoulder strap 11 is manually held to make the snap buckles 10 at both ends of the portable shoulder strap 11 snap into the snap grooves 9 opened on the connecting buckle 8, so that the portable shoulder strap 11 can be conveniently installed on both sides of the explanation device body 1. Since the connecting buckle 8 rotates in the hinge tube 6 through the hinge shaft 7, it is convenient for the user to carry the portable shoulder strap 11 on the shoulder, so as to facilitate the carrying and use of the explanation device. When carrying, the explanation device body 1 can be controlled to facilitate the use of the speaker 14 to connect with the Bluetooth-connected microphone, and the user can explain conveniently through the sound amplification effect of the speaker 14;

[0031] When it is necessary to place the explanation device in a position to watch video explanations, the portable shoulder strap 11 can be removed from both sides of the explanation device body 1 by manually pressing the snap buckle 10 in the snap slot 9, and the connecting rod 19 can be manually held to thread the connecting stud 17 into the connecting threaded tube 16 fixed on the bottom surface of the explanation device body 1, so that the support column 12 and the support plate 13 connected to one end of the connecting rod 19 through the first connecting block 20 and the second connecting block 21 can be used to stably support the explanation device body 1 in the required position, so that the display screen 4 can be used to display the knowledge of the study tour that needs to be explained, thereby making it convenient to carry and use the explanation device.
