9. The use method of the dual-video interactive teaching demonstration instrument as claimed in claim 1, comprising the steps of:
s1, before the device is used, firstly, the main screen (13) and the auxiliary screen (18) are pulled outwards along the sliding groove (20) by the sliding block (19), when the traction block (16) at the top of the main screen (13) and the auxiliary screen (18) moves to the other side of the clamping groove (17) respectively, the main screen (13) and the auxiliary screen (18) are pulled continuously, the sliding block (19) slides continuously along the sliding groove (20), the main screen (13) and the auxiliary screen (18) are pulled to the same horizontal line, at the moment, the screen is opened completely, the device can be used, meanwhile, the connecting arm (15) rotates around the rotating shaft (14) and changes from the vertical state to the horizontal state, the connection between the main screen (13) and the auxiliary screen (18) is dragged and limited, and the clamping column (27) extrudes the spring (28) under the pressure of the main screen (13) in the process of pulling and unfolding of the main screen (13), and the spring (28) is contracted towards the inside of the placing cavity (29), when the main screen (13) and the auxiliary screen (18) are opened to the same horizontal line, the pressure on the clamping column (27) disappears, and meanwhile, the clamping column (27) pops out under the elastic force action of the spring (28) and is clamped with the opening (26) at the bottom of the main screen (13) to fix the position of the main screen (13) and prevent the main screen (13) from moving in the using process of the device;
s2, when the device is used, the first motor (3) can be opened, the first motor (3) drives the rack bar (4) to rotate, the rack bar (4) drives the sleeve (5) to be driven by the limiting block (6) in the cover cylinder (2), the lifting and the moving are carried out under the limiting of the limiting groove (7), the height of the lifting seat (8) is adjusted, a user can adjust and control the heights of the main screen (13) and the auxiliary screen (18) according to the using requirement of the user, the limitation of the device on use caused by height fixing is reduced, meanwhile, the second motor (9) can be opened, the second motor (9) drives the first conical tooth (10) to rotate, the first conical tooth (10) drives the second conical tooth (11) to transmit, the rotation in the vertical direction is converted into the rotation in the horizontal direction, the rotation seat (12) is driven to rotate above the device body (1), and the main screen (13) and the auxiliary screen (18) are displayed in all directions and in multiple angles, the display effect of the device is improved, the universal wheels (24) slide along the guide grooves (25) in the rotating process of the rotating seat (12) to support the rotating seat (12), and the rotating seat (12) is ensured to rotate stably while the rotating seat (12) rotates more smoothly;
s3, the fan (22) is fixed inside the mounting groove (21) through the buckle (23), when the device is used, the heat of the main screen (13) and the auxiliary screen (18) can be dissipated, the air flow speed around the main screen (13) and the auxiliary screen (18) is accelerated, the phenomenon that the internal temperature of the main screen (13) and the auxiliary screen (18) is too high to affect the normal use performance of the device is avoided, when the device is idle, the main screen (13) and the auxiliary screen (18) are folded and stacked, the protection plate (31) is installed on the surface of the main screen (13) along the fixing plate (30), the screen of the main screen (13) is protected, the phenomenon that the screen is broken due to impact in the idle process is avoided, and economic loss is brought to a user.
