Positioning grooves are provided at the bottom end of the rotating seat 16 corresponding to the positions of the four spring locating pins 17. The rotating seat 16 cooperates with the four spring locating pins 17. When the rotating seat 16 rotates, the spring locating pins 17 will shrink under the action of the rotating seat 16, and then disengage from the corresponding positioning groove. When the rotating seat 16 rotates 180°, the spring locating pins 17 return to the corresponding positioning groove to position the rotating seat 16.

[0051] Working principle of the first embodiment: When in use, the electric telescopic rod 11 is started, and the telescopic rod of the electric telescopic rod 11 is extended to drive the display 13 and the camera 14 to rise.

[0052] After adjusting the height of the camera 14, start the motor 6, which drives the screw rod 19 to rotate. The rotation of the screw rod 19 drives the T-shaped slider 18 to move toward the direction of the rack 2, so that the T-shaped slider 18 drives the camera 14, the rotating seat 16, the connecting plate 12, the fixed rod 22, and the gear 7 to move as a whole.

[0053] During the movement of the T-shaped slider 18, the inclined surface on the fixed rod 22 will contact the inclined surface on the slide plate 3. As the fixed rod 22 continues to move, the fixed rod 22 will slide along the inclined surface on the slide plate 3 while moving, so that the fixed rod 22 slides in the direction close to the rack 2, and then the sleeve 21 slides in the direction of the rack 2 under the drive of the fixed rod 22, and the sleeve 21 pushes the gear 7 to slide in the direction of the rack 2. When the inclined surface on the fixed rod 22 is disengaged from the inclined surface on the slide plate 3, as the fixed rod 22 continues to move, the gear 7 will mesh with the rack 2, so that the gear 7 rotates, and the gear 7 drives the first rotating shaft 20 and the second slider 26 to rotate, and the second slider 26 drives the second rotating shaft 25 to rotate, and the second rotating shaft 25 The first bevel gear 8 is driven to rotate, the first bevel gear 8 drives the second bevel gear 9 to rotate, the second bevel gear 9 drives the connecting shaft 15 to rotate, the connecting shaft 15 drives the fixed seat 10, the electric telescopic rod 11, the rotating seat 16, the display 13, and the camera 14 to rotate as a whole. During the rotation of the rotating seat 16, the spring positioning pin 17 will automatically complete the extension and retraction under the action of the rotating seat 16. When the camera 14 rotates one hundred and eighty degrees, the gear 7 is disengaged from the rack 2. At this time, under the action of the first spring 28, the circular plate 24 approaches the direction of the second bevel gear 9, and the circular plate 24 pushes the second slider 26 to move. The second slider 26 drives the first rotating shaft 20 and the gear 7 to move as a whole, thereby making the gear 7, the second slider 26, and the first rotating shaft 20 move to the initial position.

[0054] When the T-shaped slider 18 moves to the end of the T-shaped slide groove 5 away from the motor 6, the motor 6 reverses, causing the T-shaped slider 18 to move toward the direction of the motor 6. During this process, the arc surface at the bottom end of the fixing rod 22 will contact the slide plate 3, and then as the fixing rod 22 moves, the fixing rod 22 will press on the upper surface of the slide plate 3 through the arc at its bottom, causing the slide plate 3 to slide downward into the third slide groove 29 until the fixing rod 22 is separated from the slide plate 3. At this time, the slide plate 3 will return to its initial position under the action of the second spring 30.

[0055] Example 2: Please refer to Figure 6-9 The difference between this embodiment and the first embodiment is that: the upper end surface of the T-shaped slider 18 is provided with a second limiting groove 38 on both sides, and the top surface of the rotating seat 16 is provided with a first limiting groove 37 on both sides. The first limiting groove 37 and the second limiting groove 38 are arranged correspondingly, and the first limiting groove 37 and the second limiting groove 38 on the same side form a square limiting groove;

[0056] A sixth slide groove 34 is provided on the inner wall of the T-shaped slide groove 5 at a side away from the first slide groove 4. A sliding column 36 is slidably installed inside the sixth slide groove 34. A limit block 35 is fixedly installed at one end of the sliding column 36 away from the sixth slide groove 34. The bottom end of the limit block 35 is slidably installed inside the limit groove. A trapezoidal groove 42 is provided on the inner wall of the sixth slide groove 34 at a position corresponding to the slide plate 3. A supporting structure is arranged inside the trapezoidal groove 42.

[0057] The supporting structure includes a trapezoidal block 41, which is fixedly installed inside the trapezoidal groove 42. There are gaps on the upper and lower sides of the trapezoidal block 41 and the trapezoidal groove 42 to allow the sliding column 36 to pass through; a fixed shaft 40 is fixedly installed at one end of the trapezoidal groove 42 close to the motor 6; a rotating plate 39 is rotatably installed on the outer circumference of the fixed shaft 40, and the rotating plate 39 is slidably matched with the trapezoidal block 41; a torsion spring is arranged between the rotating plate 39 and the fixed shaft 40.

[0058] Working principle of embodiment 2: Compared with embodiment 1, the working principle of embodiment 2 is different in that: in embodiment 2, when the T-shaped slider 18 drives the limit block 35 and the sliding column 36 to move into the trapezoidal groove 42, the T-shaped slider 18 moves to drive the sliding column 36 to slide to the upper surface of the trapezoidal block 41 through the rotating plate 39, so that the sliding column 36 drives the limit block 35 to move upward, so that the limit block 35 leaves the first limit groove 37. It should be noted that at this time, the bottom end of the limit block 35 is still located in the second limit groove 38, so that the rotating plate 39 The movable seat 16 can rotate in the groove at the top of the T-shaped slider 18. When the rotating seat 16 rotates 180°, the sliding column 36 slides from the upper surface of the trapezoidal block 41 to the gap between the trapezoidal block 41 and the sixth slide groove 34, and at the same time, the limit block 35 moves downward to the inside of the first limit groove 37. When the motor 6 reverses, the T-shaped slider 18 drives the limit block 35 and the sliding column 36 to move to the initial position, thereby realizing the limit block 35 moving up and down in the first limit groove 37 and the second limit groove 38, thereby completing the limiting of the rotating seat 16.

[0059] The other processes are the same as those in the first embodiment and will not be described in detail in this working principle.

[0060] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
