[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a teleprompter for live television broadcasting that is easy to adjust. A spherical housing support 1.1 is fixed to the middle of the rear wall of the teleprompter display screen 1. A horizontal ear plate 1.2 is fixed to the lower side of the spherical housing support 1.1 on the rear wall of the teleprompter display screen 1, and a vertical ear plate 1.3 is fixed to one side of the spherical housing support 1.1 on the rear wall of the teleprompter display screen 1. The teleprompter display screen 1 uses a high-definition touchscreen, supporting touch operation. The broadcaster can directly slide to browse and adjust the displayed content on the screen without relying on external devices. Simultaneously, the display screen has an automatic brightness adjustment function, which can automatically adjust the brightness according to the ambient light to protect the broadcaster's eyesight.

[0024] The frame 2 has mounting holes at the four corners of its bottom; these mounting holes allow the frame 2 to be easily fixed to a tripod or a tabletop.

[0025] The servo motor 3 is vertically mounted in the middle of the inner cavity of the frame 2; the bottom end of the lead screw 4 is fixedly connected to the power output shaft of the servo motor 3.

[0026] The lifting base 5 includes a threaded sleeve 5.1 that is threadedly fitted to the lead screw 4, sleeves 5.2 fixed to the two side walls of the threaded sleeve 5.1, a horizontal support plate 5.3 with its rear end fixed to the front wall of the threaded sleeve 5.1, a vertical plate 5.4 with its bottom end fixed to the front end of the horizontal support plate 5.3, and a ball-head column 5.5 fixed to the center of the front wall of the vertical plate 5.4. The horizontal support plate 5.3 has a slot 5.8 at its front middle section and the vertical plate 5.4 has a central lug 5.6 fixed to the top surface of the horizontal support plate 5.3 at the rear end of the slot 5.8, and an outer lug 5.7 fixed to the side of the horizontal support plate 5.3 near its front end. The ball-head column 5.5 is rotatably fitted into the inner cavity of the spherical shell support 1.1.

[0027] The bottom end of the guide rod 6 is vertically fixed to the top surface of the frame 2 and located on both sides of the lead screw 4. The guide rod 6 is slidably sleeved with the sleeve 5.2.

[0028] The pitch angle adjusting telescopic cylinder 7 passes through the slot 5.8, and its rear end is hinged to the middle ear seat 5.6. The front end of the pitch angle adjusting telescopic cylinder 7 is hinged to the hinge seat 7.1, and the front end of the hinge seat 7.1 is hinged to the transverse ear plate 1.2.

[0029] The rear end of the tilting telescopic cylinder 8 is hinged to the outer ear seat 5.7, and its front end is hinged to the hinge seat 8.1. The front end of the hinge seat 8.1 is hinged to the vertical ear plate 1.3.

[0030] In summary, when the height of the teleprompter display screen 1 needs to be adjusted, the servo motor 3 drives the lead screw 4 to rotate. The rotating lead screw 4, through its vertical driving action with the threaded sleeve 5.1, allows the lifting base 5 to rise and fall smoothly under the guidance of the guide rod 6. When the tilt angle of the teleprompter display screen 1 needs to be adjusted, the tilt angle adjustment telescopic cylinder 7 can be extended or shortened to achieve the tilt angle adjustment of the teleprompter display screen 1. When the tilt adjustment telescopic cylinder 8 is extended or shortened, the left and right tilt angle adjustment of the teleprompter display screen 1 can be achieved, so that the teleprompter display screen 1 can adapt to the needs of different live television broadcasts.

[0031] For ease of operation, the inner cavity of the frame 2 integrates a wireless receiver for receiving control signals from the servo motor 3, the pitch adjustment telescopic cylinder 7, and the tilt adjustment telescopic cylinder 8, and the wireless receiver signal is connected to a remote control. That is, the broadcaster can operate the teleprompter display screen 1 to adjust its height, pitch, and tilt angles using the remote control.
