[0024] 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.

[0025] Example 1: As Figures 1 to 3 As shown, this embodiment proposes a teleprompter for broadcasting and television, including a support plate 1 with a movable column 2 slidably inserted at the top, and a circular hole 11 opened on the surface of the movable column 2. A second square block 13 is hinged to the front of the support plate 1, and a threaded rod 8 is slidably inserted in the second square block 13. One end of the threaded rod 8 passes through the second square block 13 and extends into the circular hole 11. The threaded rod 8 and the circular hole 11 are inserted and arranged by threaded rotation. Multiple sets of circular holes 11 are provided, and the multiple sets of circular holes 11 are equidistantly distributed.

[0026] The fixing plate 3, LED display 5 and motor 6 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0027] In the above embodiment, the entire device is powered by an external power source. The operator starts the device via an external remote control. When the height needs to be adjusted, the threaded rod 8 is rotated out, and the moving column 2 is grasped and pulled upward to rotate the second square block 13 out of the support plate 1. After moving it to a suitable position, the second square block 13 is rotated back to its original position so that the inner side of the second square block 13 is close to the surface of the moving column 2. Then, the threaded rod 8 is inserted through the second square block 13 into the corresponding circular hole 11. The threaded rod 8 is rotated so that the support plate 1 and the circular hole 11 are fixed together by threads.

[0028] Example 2: Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, the embodiment also proposes that the top end of the moving column 2 is fixed with a fixed plate 3, and the top end of the fixed plate 3 is installed with an LED display 5, the top end of the fixed plate 3 is provided with a translucent glass 7, one side of the fixed plate 3 is installed with a liquid crystal display 4, the top end of the fixed plate 3 is installed with a motor 6, and the output end of the motor 6 is rotatably provided with a ball screw 12 through a bearing seat, the surface of the ball screw 12 is rotatably sleeved with a first square block 10 through a thread, and the surface of the first square block 10 is hinged with a connecting rod 9; the translucent glass 7 and the back of the LED display 5 are hingedly arranged; the connecting rod 9 is symmetrically provided with two groups, and the other end of the connecting rod 9 is hingedly arranged with the back of the translucent glass 7; the bottom end of the first square block 10 is left with a gap with the top end of the fixed plate 3.

[0029] In the above embodiment, when it is necessary to adjust the use angle of the translucent glass 7, the motor 6 is started, when the output end of the motor 6 drives the ball screw 12 to rotate clockwise, the first square block 10 moves to the translucent glass 7, then the use angle and direction of the two groups of connecting rods 9 are changed by the movement of the first square block 10, the use angle of the translucent glass 7 is changed, so that the angle between the translucent glass 7 and the LED display 5 becomes smaller, when it is necessary to increase the use angle, the output end of the motor 6 drives the ball screw 12 to rotate counterclockwise in the opposite direction.

[0030] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;

[0031] Secondly: the utility model discloses the embodiment in the drawing, only relate to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, under the condition of no conflict, the same embodiment and different embodiments of the utility model can be combined with each other;
