The inner wall of the storage groove 17 is fixedly connected to the liquid carrying box 27, and the bottom outer wall of the liquid carrying box 27 is fixedly connected to the nozzle transmission rod 45. The output nozzle of the nozzle transmission rod 45 is opposite to the cleaning cotton piece 21. A liquid replenishing tank cover 35 is installed on one side outer wall of the liquid carrying box 27. The inner wall of the storage groove 17 is fixedly connected to the inflation chamber 28, and the inner wall of the inflation chamber 28 is movably connected with the air bag 29. The outer walls of both sides of the inflation chamber 28 are fixedly connected with a connecting pipe 32, and the inner wall of the connecting pipe 32 is movably connected with a blocking steel ball 33. The outer wall of one side of the blocking steel ball 33 is fixed A connecting spring 34 is connected, the outer wall of one end of the sealing steel ball 33 is fixedly connected to the inner wall of the connecting tube 32, wherein the inner wall of the bottom connecting tube 32 is connected to the inner wall of the liquid carrying box 27, the inner wall of the inflation chamber 28 is fixedly connected with a rebound spring 46, the outer wall of one end of the rebound spring 46 is fixedly connected to the inner wall of the airbag 29, the inner wall of the splint 12 is provided with a connecting groove 47 connected to the inner wall of the pen holder 11, the inner wall of the connecting groove 47 is slidably connected with an arc plate 1 30, the outer wall of one side of the capacitive pen 13 is fixedly connected with an arc plate 2 31, and the outer wall of one side of the arc plate 21 is movably connected to the outer wall of one side of the arc plate 1 30.

In the present invention, the teaching staff can take out the capacitive pen 13 for use by pressing the capacitive pen 13 in the pen holder 11 with the thumb to push the capacitive pen 13 upward. When the capacitive pen 13 moves upward, the arc plate 2 31 will press against the arc plate 1 30, thereby driving the arc plate 1 30 to slide to one side. At this time, the arc plate 1 30 will squeeze the air bag 29, and a one-way valve structure is formed by the combination of the connecting tube 32, the blocking steel ball 33 and the connecting spring 34, so that the air can only flow in one direction. After the air bag 29 squeezes the air in the inflation chamber 28, the air is pumped into the liquid carrier 27 by using the one-way valve structure. In the present invention, the liquid carrier 27 is loaded with cleaning alcohol, and the pump pressure of the upper air in the liquid carrier 27 causes the cleaning alcohol to pass along the nozzle below. 45 is squeezed out, sprayed and soaked in the cleaning cotton sheet 21. At this time, the capacitive pen 13 continues to move upward. Through the magnetic connection between the magnetic plate 1 26 and the magnetic plate 2 44, the capacitive pen 13 will drive the rack 23 and the slider 24 to move synchronously in the movable groove 25. When the cleaning cotton sheet 21 is completely soaked in alcohol, the rack 23 will mesh with the outer wall of the half gear 22, and the meshing rotation will drive the extension shaft 20 to rotate synchronously with the rotating shaft 18 as the axis, so that the cleaning cotton sheet 21 scrapes the main control camera 42's outer wall, thereby cleaning the main control camera 42 and improving the shooting clarity of the main control camera 42. At this time, the extended shaft 20 naturally hangs down. When the teaching work is finished, the worker inserts the capacitive pen 13 back into the pen holder 11. At this time, the magnetic suction plate 1 26 and the magnetic suction plate 2 44 are magnetically adsorbed again, driving the rack 23 to move downward and engage with the half gear 22, further driving the extended shaft 20 to transfer back to the upper end, and being adsorbed and fixed by the limiting magnetic suction block 1 48 and the limiting magnetic suction block 2 49.

[0040] The working principle and use process of the present invention are as follows: In the present invention, a stabilizing clip 9 is used to clamp the smart teaching terminal 10 facing the teaching worker, and the main control camera 42 is used to shoot the educator through the smart teaching terminal 10 to conduct remote video teaching. When the teaching worker needs to use the panoramic virtual modeling technology for teaching, the panoramic virtual modeling may exceed the shooting range of the main control camera 42, and the educator needs to adjust the camera position shooting angle of the smart teaching terminal 10 in real time. In the present invention, the worker can take out the capacitive pen 13 placed on the pen holder 11, and while using the capacitive pen 13 to assist teaching, pressing the start button 14 can make the infrared transmitter 15 emit infrared frequency bands, and the infrared motion connected to the infrared signal of the infrared transmitter 15 The sensor receiver 16 receives the infrared frequency band and converts it into an electrical signal and transmits it to the cluster processor 39. The cluster processor 39 calculates the fluctuation distance of the infrared frequency band in real time, thereby calculating the moving direction and distance of the capacitive pen 13, and realizing real-time tracking and monitoring of the capacitive pen 13. Further, it is converted into an adjustment instruction and transmitted to the bidirectional running motor 40 and the Hall position sensor 41, and the bidirectional running motor 40 is started to drive the smart teaching terminal 10 to rotate for angle adjustment, so that the worker can freely control the shooting angle to achieve the effect of fixing the angle or adjusting the angle in real time following the worker, so that the panoramic virtual space can be flexibly used for teaching, providing better teaching effect. In the present invention, since the smart teaching terminal 10 needs to be controlled by the main control The camera 42 performs real-time shooting, and the virtual projection needs to ensure the shooting clarity to perform algorithm recognition on the object. When the main control camera 42 is stained with dust, it is easy to affect the shooting clarity. In the present invention, the teaching staff can take out the capacitive pen 13 for use by pressing the capacitive pen 13 in the pen holder 11 with the thumb to push the capacitive pen 13 upward. When the capacitive pen 13 moves upward, the arc plate 21 will press against the arc plate 1 30, thereby driving the arc plate 1 30 to slide to one side. At this time, the arc plate 1 30 will squeeze the airbag 29, and a one-way valve structure is formed by the combination of the connecting tube 32, the blocking steel ball 33 and the connecting spring 34, so that the air can only flow in one direction. After the airbag 29 squeezes the air in the inflation chamber 28 using the one-way valve structure, the air pump is pressed to In the liquid carrier tank 27, the liquid carrier tank 27 of the present invention is loaded with cleaning alcohol. The pump pressure of the upper air in the liquid carrier tank 27 causes the cleaning alcohol to be squeezed out along the nozzle transmission rod 45 below, spraying and soaking the cleaning cotton sheet 21. At this time, the capacitive pen 13 continues to move upward, and through the magnetic connection between the magnetic suction plate 1 26 and the magnetic suction plate 2 44, the capacitive pen 13 will drive the rack 23 and the slider 24 to move synchronously in the movable groove 25. When the cleaning cotton sheet 21 is completely soaked in alcohol, the rack 23 will mesh with the outer wall of the half gear 22, and the meshing rotation will drive the extension shaft 20 to rotate synchronously with the rotating shaft 18 as the axis, so that the cleaning cotton sheet 21 scrapes the outer wall of the main control camera 42, thereby cleaning the main control camera 42 and improving the shooting clarity of the main control camera 42.At this time, the extended shaft 20 naturally hangs down. When the teaching work is finished, the worker inserts the capacitive pen 13 back into the pen holder 11. At this time, the magnetic plate 1 26 and the magnetic plate 2 44 are magnetically adsorbed again, driving the rack 23 to move downward and mesh with the half gear 22, further driving the extended shaft 20 to return to the upper end, and is adsorbed and fixed by the limiting magnetic block 1 48 and the limiting magnetic block 2 49.
