The inner wall of the base 1 is rotatably connected to a gear 2 64, and the gear 2 64 is meshed with the gear 1 5. A socket 65 is provided at the top of the gear 2 64. The shape and size of the plug rod 63 match the socket 65. The outer wall of the plug rod 63 is slidably connected to the inner wall of the socket 65. The top of the plug rod 63 is fixedly connected to a control switch 66. A thread for easy rotation is provided on the outer wall of the control switch 66. The rotation center of the control switch 66 and the rotation center of the gear 2 64 are in the same vertical plane.
[0040] Reference Figure 2 , Figure 3 and Figure 5 The base 1 is provided with a conversion assembly 7 inside, which includes an air pressure tube 71, the air pressure tube 71 has good internal airtightness, the outer wall of the air pressure tube 71 passes through and is fixedly connected to the inner wall of the base 1, the inner wall piston of the air pressure tube 71 is connected to a starting block 72, the outer wall of the starting block 72 fits with the inner wall of the air pressure tube 71, the top of the starting block 72 is fixedly connected to the bottom end of the control panel 62, the inner wall piston of the air pressure tube 71 away from the starting block 72 is connected to a push block 73, the outer wall of the push block 73 fits with the inner wall of the air pressure tube 71, and the conversion assembly 7 also includes a rotating groove 74, the rotating groove 74 is in the shape of a circular ring, the rotating groove 74 is opened on the inner wall of the base 1, and the inner wall of the base 1 below the rotating groove 74 is opened with a fixed groove 75, the rotating groove 74 is connected to the fixed groove 75, and the outer wall of the push block 73 passes through the inner wall of the base 1 at the lower end of the fixed groove 75.
[0041] Reference Figure 2 , Figure 3 and Figure 5 A control tube 76 runs through the inner wall of the base 1, and a chuck 77 is fixedly connected to the bottom end of the control tube 76. The shape of the fixed groove 75 is similar to the shape remaining after a circular ring is cut off with multiple rectangular blocks, and the rectangular area of the fixed groove 75 fits with the upper end of the chuck 77. Through the matching shape setting, it is ensured that the chuck 77 cannot rotate after entering the fixed groove 75. The height of the chuck 77 is shorter than the height of the rotating groove 74. The bottom of the chuck 77 is set as a pointed end. Through the setting of the pointed end, it is ensured that the chuck 77 can enter the fixed groove 75 more easily. A moving groove 78 is opened on the outer wall of the control tube 76, and the moving block 3 is arranged inside the moving groove 78. Through the setting of the moving groove 78, it is ensured that the object inside the control tube 76 can be connected with the external object.
[0042] Reference Figure 2 , Figure 5 and Figure 6 A fixing assembly 8 is provided between the rear end of the moving block 3 and the inner wall of the control tube 76. The fixing assembly 8 includes a mounting groove 81. The mounting groove 81 is opened at the rear end of the moving block 3. A connecting ball 82 is slidably connected to the inner wall of the mounting groove 81. The sliding direction of the connecting ball 82 is horizontal sliding. The front end of the connecting ball 82 is elastically connected to the inner wall of the mounting groove 81 through a spring 83. One end of the spring 83 is fixedly connected to the front end of the connecting ball 82, and the other end of the spring 83 is fixedly connected to the inner wall of the mounting groove 81. The end of the connecting ball 82 away from the spring 83 is spherical. The control tube 76 is provided with a fixing hole 84, which ensures that the connecting ball 82 can enter the fixing hole 84 through the matching shape setting, and the number of the fixing holes 84 is set to be several, and the fixing holes 84 are in a linear array in the vertical direction. The number and position setting of the fixing holes 84 ensures that no matter what vertical position the moving block 3 is in, there is a suitable fixing hole 84 that matches the connecting ball 82.
[0043] Working principle: When in use, when the height needs to be adjusted, the user directly turns the control switch 66, so that the control switch 66 drives the control disk 62 to rotate, so that the control disk 62 drives the insertion rod 63 to rotate, and the gear 2 64 rotates through the insertion rod 63.
[0044] When gear 2 64 rotates, it drives gear 1 5 to rotate, so that screw 9 is driven by gear 1 5 to rotate. At this time, since the control tube 76 is affected by gravity and has no other upward force, the chuck 77 is inside the fixed groove 75. Therefore, when the screw 9 rotates, the control tube 76 cannot rotate, and the moving block 3 cannot rotate because it is inside the moving groove 78. Therefore, the moving block 3 moves up and down, and drives the bracket 4 and the display screen body 2 to move up and down.
[0045] When the rotation angle needs to be adjusted, the user first presses the control switch 66 downward. At this time, the control switch 66 drives the rotating rod 61 to move downward, so that the rotating rod 61 drives the starting block 72 to move downward, and the gas pressure inside the air pressure tube 71 increases through the entry of the starting block 72, so that the push block 73 moves upward. At this time, the chuck 77 is subjected to an upward force, so it moves to the inside of the rotating groove 74.
[0046] At this time, the staff turns the control switch 66 to rotate the screw 9. Since the connecting ball 82 is located inside the fixing hole 84 under the elastic force of the spring 83, when the screw 9 rotates, the control tube 76 and the moving block 3 are not affected by other forces. Therefore, they rotate with the screw 9 under the action of friction force, thereby achieving the effect of adjusting the rotation angle.
[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
