[0035] Reference Figure 1 , Figure 4 and Figure 6 The limiting mechanism 2 includes two extended cup walls 202, which restrict the position of the teacup and provide protection. The bottoms of the two extended cup walls 202 are respectively located at the front and rear ends of the top right side of the extended handle 10, providing a mounting base for the extended cup walls 202. Teacup slots 201 are provided at the front and rear ends of the top right side of the extended handle 10 for placing teacups. The bottom inner sides of the two extended cup walls 202 are fixedly connected to the top of the teacup slots 201 to enhance structural stability. Heating pads 203 are fixedly connected to the bottom inner walls of the two teacup slots 201 to heat the beverage in the teacup. Limiting rings 204 are fixedly connected to the inner walls of the two extended cup walls 202 to assist in fixing the teacup. To prevent excessive shaking of the teacup, the inner walls of the two limiting rings 204 are provided with slots 205 around the perimeter, providing installation positions for the rotating shaft 206 and clamping blocks 207. The top of the inner walls of the multiple slots 205 are rotatably connected to the rotating shaft 206, allowing the clamping blocks 207 to rotate around it, thus adapting to teacups of different sizes. The outer walls of the multiple rotating shafts 206 are rotatably connected to the clamping blocks 207 for directly clamping the teacup. The bottom of one side of the multiple clamping blocks 207 is fixedly connected to a spring 208, using elastic force to assist the clamping blocks 207 in clamping the teacup.

[0036] Specifically, when a water cup needs to be placed, the two extended cup walls 202 on the extended handle 10 are respectively located at the front and rear ends of its top right side. The bottom inner side of the extended cup wall 202 is fixedly connected to the top of the teacup slot 201, providing side protection and limiting for the teacup. When the beverage in the teacup needs to be heated, the heating pad 203 can be turned on to generate heat to heat the teacup and ensure the beverage is at a suitable temperature. The rotating shaft 206 rotatably connected to the top of the inner wall of the slot 205 allows the clamping block 207 to rotate around the rotating shaft 206. When the teacup is placed in, it will squeeze the clamping block 207. 7. When the force is applied, the spring 208 connecting the bottom of one side of the clamping block 207 to the inner wall of the slot 205 is stretched. The spring 208 has elastic restoring force. When the teacup is placed in the appropriate position and no longer squeezes the clamping block 207, the spring 208 contracts, driving the clamping block 207 to move towards the teacup. Multiple clamping blocks 207 clamp and limit the teacup from all sides to prevent the teacup from shaking and tipping over during placement, ensuring that the teacup is stably placed in the teacup slot 201. The limiting mechanism 2 realizes the stable and reliable limiting and heating functions of the water cup, providing convenience and safety for the user.

[0037] Reference Figure 1 , Figure 2 and Figure 5 Each of the multiple clamping blocks 207 has a pad 14 fixedly connected to its other side. The pad 14 increases the friction between the clamping block 207 and the contacting object. The other side of each pad 14 is roughened to further increase the friction and make the clamping more stable. Each of the two sliders 8 has a limit block 15 fixedly connected to its top right side to ensure structural stability. Each of the two slide grooves 11 has a limit groove 16 on its inner top wall to provide sliding space and limit the range of movement. The two limit blocks 15 are slidably connected inside the corresponding limit grooves 16 to ensure that the slider 8 and the slide groove 11 are precisely matched when the extension hand support 10 slides. The top of the extension hand support 10 is fixed. A controller 17 is fixedly connected to enable automatic adjustment. The controller 17 is electrically connected to two hydraulic rods 29 and a heating pad 203 to enable function adjustment. A screen 18 is fixedly connected to the right side of the controller 17. The screen 18 can display relevant adjustment parameters and status information. A housing 19 is fixedly connected around the screen 18 to protect it. A handle 24 is fixedly connected to the other side of each of the multiple pull rods 20. The handle 24 makes it easier for users to pull the pull rods 20 and makes operation more convenient. The outer walls of the multiple handles 24 are roughened to increase the friction between the hand and the handle 24 and prevent slippage during operation.

[0038] Specifically, the pad 14 increases the contact area between the clamping block 207 and the clamped object, preventing damage to the item. The limiting block 15 slides within the limiting groove 16, ensuring smooth sliding of the extension hand support 10 within the extension groove 7 and preventing the slider 8 from disengaging from the slide groove 11. This ensures the structural stability of the extension hand support 10 during movement, making the extension and retraction operations of the extension hand support 10 more reliable. The controller 17 controls the extension and retraction of the hydraulic rod 29, thereby adjusting the extension and retraction of the extension hand support 10. It also regulates the temperature of the heating pad 203, providing a warm and comfortable experience for users and meeting the needs of different users in different environments. The screen 18 displays various information intuitively, allowing users to understand the device's operation at any time for appropriate adjustments. The outer shell 19 protects the screen 18 and extends its service life. The roughened outer wall of the handle 24 increases the friction between the hand and the handle 24, ensuring that the user can pull the lever 20 stably and smoothly.

[0039] Working principle: When the protective cover 23 needs to be removed, pull the lever 20, which moves the limiting ball 21 fixed at one end synchronously, causing the limiting ball 21 to disengage from the inside of the engagement groove 12. As the limiting ball 21 disengages, the locking block 22 is no longer restricted by the limiting ball 21. At this time, the locking block 22 connected to the front and rear connecting blocks 13 at the bottom of the protective cover 23 can slide freely in the engagement groove 3, thereby allowing the protective cover 23 to be quickly removed from the armrest support 5. This design makes the operation of replacing the protective cover 23 simple and convenient, improving the practicality of the seat armrest integrated device. In terms of adjustment components, the armrest support... An expansion groove 7 is provided on the right side of the hand support 5. A slider 8 is fixedly connected to the front and rear ends of the bottom of the inner wall of the expansion groove 7. A hydraulic rod 9 is fixedly connected to the front and rear ends of the left side of the inner wall. The other ends of the two hydraulic rods 9 are connected to the same expansion hand support 10. The expansion hand support 10 is slidably connected inside the expansion groove 7. The sliding grooves 11 opened on the front and rear sides of its bottom cooperate with the slider 8. When it is necessary to expand the hand support area, the hydraulic rod 9 is activated. The hydraulic rod 9 extends and pushes the expansion hand support 10 to slide outward along the expansion groove 7. The slider 8 slides in the sliding groove 11 to guide and stabilize. The smooth extension of the expansion hand support 10 provides a larger support area for the user.

[0040] Furthermore, when a water cup needs to be placed, the two extended cup walls 202 on the extended handle 10 are respectively located at the front and rear ends of its top right side. The bottom inner side of the extended cup wall 202 is fixedly connected to the top of the teacup slot 201, providing side protection and a limiting base for the teacup. When the beverage in the teacup needs to be heated, the heating pad 203 can be turned on to heat the teacup and ensure the beverage is at a suitable temperature. The rotating shaft 206 rotatably connected to the top of the inner wall of the slot 205 allows the clamping block 207 to rotate around the rotating shaft 206. When the teacup is placed in, it will squeeze the clamping block 207. When the force rotates around the pivot 206, the spring 208 connecting the bottom of one side of the clamping block 207 to the inner wall of the slot 205 is stretched. The spring 208 has elastic restoring force. When the teacup is placed in the appropriate position and no longer squeezes the clamping block 207, the spring 208 contracts, driving the clamping block 207 to move towards the teacup. Multiple clamping blocks 207 clamp and limit the teacup from all sides, preventing the teacup from shaking and tipping over during placement, ensuring that the teacup is stably placed in the teacup slot 201. The limiting mechanism 2 realizes a stable and reliable limiting and heating function for the water cup, providing convenience and safety for the user.
