The fixed rod 13 is arranged at the front end of the pressing rod 7 and is used to support the movement of the pressing rod 7. The spring 14 is arranged on the outer periphery of the fixed rod 13 and is used to reset the movement of the pressing rod 7.

[0031] A first limit frame 17 is fixedly connected to the top of the first support rod 15. A second limit frame 18 is fixedly connected to the right side of the second support rod 16. An automatic retractable component is arranged on the opposite sides of the first limit frame 17 and the second limit frame 18. Multiple mounting holes 2 are opened at both ends of the sunshade cloth 1. The multiple mounting rods 4 are respectively slidably connected inside the multiple mounting holes 2. Two card slots 5 are opened on the outer periphery of the mounting rod 4. The two sliding rods 11 are respectively clamped inside the two card slots 5. Two sliding rods 12 are fixedly connected inside the fixed block 6. The two sliding rods 11 are respectively slidably connected to the outer peripheries of the two sliding rods 12.

[0032] Specifically, the first support rod 15 and the second support rod 16 are used to support the device. The first limit frame 17 and the second limit frame 18 are used to support the automatic retractable component. The mounting holes 2 are arranged on the sunshade cloth 1 and are used to align the mounting holes 2 with the mounting rods 4 for installation. The card slots 5 are arranged on the mounting rod 4 and are used to insert the sliding rod 11 into the card slot 5 to fix the fixed block 6 on the mounting rod 4.

[0033] Please refer to Figure 1 andFigure 4 In this embodiment, the automatic retracting and deploying assembly includes a threaded rod 19. The two ends of the threaded rod 19 are respectively rotatably connected to the opposite sides of a first limiting frame 17 and a second limiting frame 18. A rotating block 20 is rotatably connected to the outer periphery of the threaded rod 19. The rotating block 20 is rotatably connected to the left side of the second limiting frame 18. A plurality of driven sliders 21 are slidably connected to the outer periphery of the threaded rod 19. A driving slider 22 is threadedly connected to the outer periphery of the threaded rod 19. The rotating block 20, the plurality of driven sliders 21 and the driving slider 22 are respectively fixedly connected to the outer peripheries of a plurality of mounting blocks 3. A driving assembly is arranged on the left side of the first limiting frame 17. The driving assembly includes a motor 23. The motor 23 is fixedly connected to the left side of the first limiting frame 17. The output end of the motor 23 is fixedly connected to the left side of the threaded rod 19. All the driven sliders 21 are located on the left side of the rotating block 20, and the driving slider 22 is located on the left side of the driven sliders 21.

[0034] Specifically, the threaded rod 19 is arranged between the first limiting frame 17 and the second limiting frame 18 and is used to drive the driving slider 22 to move when rotating. A rotating block 20 is arranged on the threaded rod 19. The rotating block 20 can only rotate on the threaded rod 19 and cannot move, so as to support a corner of the sunshade cloth 1. The driven sliders 21 move on the threaded rod 19 but are not in threaded cooperation with the threaded rod 19 and are used to support the middle part of the sunshade cloth 1. The driving slider 22 cooperates with the threaded rod 19 to support the other side of the sunshade cloth 1 and is used to control the retracting and deploying of the sunshade cloth 1. The motor 23 is arranged on the left side of the first limiting frame 17 and is used to control the movement of the threaded rod 19.

[0035] The working principle and usage process of the present utility model are as follows: The operator installs the installation holes 2 on the sunshade cloth 1 by aligning them with the installation rod 4. Then, take out the fixing block 6 and press the pressing rod 7. When the pressing rod 7 is pressed down, it will drive the support frame 8 to move. The support frame 8 will drive the sliding frame 10 to move through the connecting rod 9. The sliding frame 10 will pull the sliding rod 11 into the fixing block 6, thereby installing the fixing block 6 on the installation rod 4. Then, release the pressure on the pressing rod 7, so that the spring 14 releases the tension and resets the pressing rod 7, thereby making the sliding rod 11 snap into the card slot 5 on the pressing rod 7, thereby fixing the fixing block 6 on the installation rod 4 and fixing the sunshade cloth 1 on the installation rod 4. Then, install all the installation holes 2 by aligning them with the installation rod 4 through the above steps to complete the installation of the sunshade cloth 1. To disassemble the sunshade cloth 1, just press the pressing rod 7 to remove the fixing block 6, and then the sunshade cloth 1 can be removed.

[0036] When it is necessary to retract the sunshade cloth 1, the operator needs to drive the motor 23 to rotate, thereby driving the threaded rod 19 to rotate. When the threaded rod 19 rotates, it will drive the active slider 22 to move to the right. During the movement, it will drive a plurality of driven sliders 21 to move beside the rotating block 20, thus completing the retraction of the sunshade cloth 1. When it is necessary to deploy the sunshade cloth 1, the operator needs to drive the motor 23 to reverse, driving the active slider 22 to move to the left. While the active slider 22 is moving to the left, it will sequentially drive the driven sliders 21 to move to the left by means of the sunshade cloth 1. When it moves to the leftmost side, the deployment of the sunshade cloth 1 can be completed, thereby making the retraction and deployment of the sunshade cloth 1 automated.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
