[0046] 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.

The bottom of the lifting tube extends and retracts within the hollow tube. In this embodiment, the base and hollow tube are conventional structures of the prior art. The base is for placement on the ground plane, and the control circuit board is a conventional circuit board of the prior art, which is equipped with a power management circuit, a drive circuit, a sensing signal receiving circuit, and a wireless communication circuit, enabling power management and remote control operations, mainly for drive control operations of various structural parts. The size of the lifting tube is matched with the inner cavity of the hollow tube, allowing the lifting tube to be adjusted in height within the hollow tube. In this embodiment, the control circuit board is provided with a module expansion interface. This allows for quick replacement of multi-functional modules, improving the convenience and effectiveness of connection expansion.

[0048] In this embodiment, a rotary drive structure 7 is fixed to the top of the lifting tube body, and a fixed seat 8 is provided on the top of the rotary drive structure. An angle adjustment drive structure 9 is fixed inside the fixed seat, and a connecting seat 10 for installing electrical structures is fixed on the angle adjustment drive structure. During connection, the control circuit board is connected to the lifting drive structure, the rotary drive structure, and the angle adjustment drive structure. In use, the lifting drive structure drives the lifting tube body to rise and fall within the main control seat and the hollow tube body, realizing adjustment control at different heights. The rotary drive structure drives the fixed seat to rotate horizontally, enabling adjustment control in different directions. The angle adjustment drive structure drives the connecting seat to achieve upward and downward angle adjustment. Pitch angle adjustment control can be achieved. Through the above structure, not only vertical lifting operation, but also horizontal rotation operation and angle adjustment operation can be realized. In this embodiment, the angle adjustment range is -90° to +90°, and the rotation angle is 360 degrees.

[0049] In practical applications, the lifting drive structure includes a first drive motor 51 and a drive gear 52 fixed on the main shaft of the first drive motor. A vertical transmission rack 11 is provided on the side of the lifting tube, and the drive gear meshes with the transmission rack. The drive gear rotates, causing the transmission rack to rise and fall. In this embodiment, the main control unit is a combination of a front seat and a rear seat fixed with screws. The first drive motor is fixed to either the front or rear seat and has a corresponding power input connector. The transmission rack can be integrally machined onto the lifting tube or fixed to the side wall of the lifting tube with screws. Its main function is to cooperate with the drive gear to achieve lifting drive control. Furthermore, in practical applications, the transmission rack has several limiting magnets, which are mainly used to cooperate with sensors to achieve sensing and limiting during lifting, and the sensors send sensing signals to the control circuit board.

[0050] In practical applications, the rotary drive structure includes a second drive motor 71, a fixed cover 72, a first conductive ring 73, and a conductive pin 74. During assembly, the spindle of the second drive motor is fixed to the top of the lifting tube, the fixed cover is fixed to the mounting base of the second drive motor, and the conductive pin is fixed to either the fixed cover or the mounting base of the second drive motor. The second drive motor is fixed to the top of the lifting tube via the mounting base, which is a conventional structure in the prior art, mainly used to install and fix the second drive motor to the top of the lifting tube, ensuring the stability and reliability of the installation. The fixed base is connected to the spindle of the second drive motor, the first conductive ring is fixed to the bottom surface of the fixed base, and the conductive pin is electrically connected to the first conductive ring by pressure. Through the cooperation of the first conductive ring and the conductive pin, power connection can be achieved while rotating, ensuring stable and reliable operation. In this embodiment, the conductive pin can be replaced by a conductive contact piece or other common conductive structures, all of which are within the scope of protection of this technical solution.

[0051] Furthermore, in this embodiment, the angle adjustment drive structure includes a third drive motor 91, a second conductive ring 92, and a motor support 93. In this embodiment, the third drive motor is a conventional structure of the prior art, containing a worm gear structure. The worm gear structure drives the main shaft of the third drive motor to rotate synchronously, thereby driving the connecting seat connected to the main shaft to achieve swing angle adjustment. During assembly, the motor support is fixed to the fixed base, the third drive motor is fixed to the motor support, and the main shaft of the third drive motor extends laterally out of the motor support. The third drive motor is electrically connected to the first conductive ring. The second conductive ring is fixed to the symmetrical side of the motor support and electrically connected to the first conductive ring, with the main shaft of the third drive motor located at the center of the second conductive ring. The connecting seat is fixed to the main shaft of the third drive motor. Power can be drawn through the second power-taking ring in conjunction with conductive contacts, thus ensuring the stability and reliability of the power supply to electrical appliances during connection.

[0052] In this embodiment, the connector includes an n-shaped base 101, conductive contacts 102, a connecting circuit board 103, and a connector cover 104. The connecting circuit board has a common structure in the prior art, with a corresponding TYPE-C interface supporting USB connection for power supply to electrical appliances. During assembly, the conductive contacts are fixed to the symmetrical inner walls of the n-shaped base, the motor support is located within the recessed area of ​​the n-shaped base, the main shaft of the third drive motor is rotatably connected to the inner wall of the n-shaped base, and the conductive contacts are electrically connected to the second conductive ring. The connecting circuit board is fixed to the top surface of the n-shaped base and electrically connected to the conductive contacts. The connector cover is fixed to the top surface of the n-shaped base and has a plug-in port for connection to the connecting circuit board. In this embodiment, the conductive contacts can be replaced with power-taking pins or other common conductive structures, all of which are within the scope of this technical solution.

[0053] In this embodiment, to improve the convenience and efficiency of assembly, a connecting fixing frame 12 is provided on the symmetrical outer wall of the n-shaped base, and a movable cover 13 is snapped onto the outer side of the connecting fixing frame; the main shaft of the third drive motor is fixed to the connecting fixing frame. The connecting fixing frame is fixed with screws, and the movable cover enhances the decorative aesthetics of the overall structure;

[0054] In practical applications, the outer wall of the connecting seat cover is provided with at least three snap-fit ​​holes, and the top inner wall of the n-shaped seat body is provided with snap-fit ​​protrusions that mate with the snap-fit ​​holes; the connecting seat cover is snapped into the n-shaped seat body, and the snap-fit ​​protrusions are snapped into the snap-fit ​​holes. This improves the ease and stability of connection of the connecting seat cover, and the reliability of the connection is improved through at least three-point positioning.

[0055] In this embodiment, sensors 14 connected to the control circuit board are installed inside both the fixed cover and the motor support. Several limiting magnets 16 cooperating with the sensors are installed on the fixed cover, the connecting seat, and the transmission rack. The sensors can sense the position of the limiting magnets and limit their movement. The sensors are used to sense the corresponding rotation angle or lifting height and provide corresponding parameter data to the control circuit board, facilitating the effectiveness and accuracy of subsequent control. The limiting magnets are mainly used when the sensor senses the position signal of the limiting magnets and limits their movement during rotation or when the transmission rack is raised or lowered. Simultaneously, the sensed signal is sent to the control circuit board. In practical applications, limiting magnets are also installed on the connecting frame. During rotation, the sensor senses different limiting magnet positions and limits the movement when the sensor detects a limiting magnet. In practical applications, the number of limiting magnets can be multiple to meet the sensing needs of different positions, thereby achieving limiting operations at different positions.

[0056] In this embodiment, the connecting seat is provided with a movable self-locking structure 15 for locking electrical appliances. The movable self-locking structure includes a movable seat 151, a movable seat cover 152 disposed inside the movable seat, a movable block 153 disposed inside the movable seat cover, a self-locking frame 154 disposed on the movable block, and an adjusting spring 155 disposed between the symmetrical side of the movable seat cover and the movable seat; a button 156 connected to the self-locking frame is disposed on the front of the movable seat cover, and a pressure spring 157 is disposed between the self-locking frame and the inner wall of the movable seat cover, the pressure spring and the button being disposed on the symmetrical side of the self-locking frame. In use, the moving seat is pushed by adjusting the force of the spring, and the compression spring creates a self-repairing force on the self-locking frame, so that the self-locking frame and the moving block are tightly attached and engaged. When the button is pushed, the tightly attached moving seat cover moves together and drives the self-locking frame, causing the self-locking frame to disengage from the moving block. The moving seat moves to one side due to the original force. Conversely, pushing the moving seat slides the button, and the self-locking frame will connect with the moving block due to the engagement, forming a self-locking effect that locks the moving seat and fixes it.

[0057] This utility model has the following positive effects: Its structure is rationally designed, incorporating a lifting drive structure, a rotation drive structure, and an angle adjustment drive structure. Combined with a control circuit board, it enables adjustments to lifting, horizontal rotation, and tilt angle, improving ease of use. The connecting base allows for quick clamping and positioning of electrical appliances, eliminating the need for manual hand operation and enhancing stability. Furthermore, the control circuit board improves the precision of adjustment, enabling accurate control and further enhancing usability. It can meet the needs of various scenarios, has low overall cost, and is highly adaptable. Example

[0058] See Figure 9As shown, this embodiment is basically the same as Embodiment 1, except that: the main control base is directly fixed to the mounting plate with screws, and a lifting tube body that cooperates with the lifting drive structure passes through the main control base; the main control base is provided with several mounting holes for fixing to the wall or board. The mounting plate is fixed to the wall with screws or glue. To facilitate connection, the main control base has multiple holes for screws to pass through. The mounting plate is made of plastic, metal, or wood, which reduces the use of the base and hollow tube body, improving the flexibility of use. Furthermore, the main control base can also be directly fixed to the wall with screws.

[0059] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here.
