[0044] The working principle and use process of the utility model are as follows: when in use, the base 1 is placed on the table, at which time the display screen body 3 is already in front of the hollow column 2, and the motor 5 located behind the display screen body 3 is started, and the motor 5 drives the threaded rod 8 at the output end to rotate, and the moving block 9 on the outer side of the threaded rod 8 is affected by the internal thread thereof and begins to move upward to the top of the threaded rod 8, at which time the hollow rod 6 on the outer end face of the moving block 9 drives the fixing plate 7 to move upward, until the moving block 9 moves to the top of the hollow shell 4 and stops, pinch the hollow rod 6 and rotate it upward, The hollow rod 6 is rotated along the circular groove on the outer end surface of the moving block 9 with the damping plate 10 as the base point until the hollow rod 6 and the display screen body 3 are both longitudinally fixed, and the metal plate 17 with the cleaning strip 18 is taken out, and the side of the metal plate 17 without the cleaning strip 18 is inserted into the square groove of the fixed plate 7 near the end of the display screen body 3. At this time, the magnetic sheet 16 fixed in the square groove magnetically fixes the metal plate 17, and the cleaning strip 18 is installed. When installing the cleaning strip 18, the fixed plate 7 needs to be lifted upward, and the sliding rod 1 connected to the tail end of the fixed plate 7 2 drives the tension spring 11 and slides upward along the inside of the hollow rod 6. When the cleaning strip 18 is installed, the fixing plate 7 is released, and the tension spring 11 drives the sliding rod 12 to retract toward the tail end of the hollow rod 6; when water is splashed onto the display screen body 3, the hollow rod 6 can be rotated so that the position of the hollow rod 6 is 90 degrees vertical to the display screen body 3. At this time, the cleaning strip 18 at the top end of the front side of the hollow rod 6 contacts the front end surface of the display screen body 3, and the motor 5 is started. The motor 5 drives the threaded rod 8 to reverse, and the moving block 9 outside the threaded rod 8 drives the hollow rod 6 and the cleaning strip 18 The cleaning strip 18 wipes and absorbs the water stains on the display screen body 3 while spreading the force to the entire display screen body 3, making it difficult for uneven force to affect the display of the display screen body 3. When preventing the table on which the display screen body 3 rests from shaking, the vibration will first be transmitted to the inside of the hollow column 2. A shock-absorbing compression spring 13 is arranged at the bottom of the hollow column 2, and a damping layer is arranged on the outside of the sliding block 14 at the top of the compression spring 13, which can reduce the vibration and avoid the situation where the screen shakes with the table due to the shaking of the table.
