[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The inner wall of the sliding seat 7 is slidably connected to the outer wall of the telescopic rod 9. The bottom of the telescopic rod 9 is fixedly connected with a rotating disk 10. The outer wall of the rotating disk 10 is rotatably connected to the inside of the connecting base 2. The inside of the connecting base 2 is slidably connected with a clamping assembly, and the clamping assembly includes a clamping block 11. The outer wall of the clamping block 11 is slidably connected to the inside of the connecting base 2. The upper surface of the clamping block 11 is fixedly connected with a guide plate 12, and the outer wall of the guide plate 12 is slidably connected to the inside of the connecting base 2;
[0026] Specifically, firstly, the connecting column 1 and the connecting base 2 are accurately passed through the workpiece to be connected, and then the connecting base 2 is placed at a predetermined position inside the workpiece to ensure that it fits tightly with the surface of the workpiece, and then the handle 4 is pressed to drive the sliding block 5 and the limiting block 6 to slide smoothly inside the fixed column 3. During the sliding process, the limiting block 6 will gradually move downward along the U-shaped slide preset inside the fixed column 3, and the spring 8 will shrink under pressure. When the limiting block 6 slides to the bottom of the slide, start to turn the handle 4, which will drive the limiting block 6 to continue sliding inside the slide, and at the same time drive the rotating disk 10 to rotate through the telescopic rod 9. In this process, The clamping block 11 will slide in the arc-shaped slideway inside the rotating disk 10 and gradually move into the inside of the workpiece. Then the pressure on the handle 4 will be released. At this time, the spring 8 will no longer be compressed by external force, and will begin to rebound and push the sliding block 5 to move upward. Driven by the sliding block 5, the limit block 6 will be fixed inside the slideway to ensure the stability and reliability of the entire connection structure. In this process, the rotation of the rotating disk 10 will drive the clamping block 11 to move accurately to the inside of the workpiece to be connected. At the same time, the guide plate 12 will guide the movement of the clamping block 11, ensuring that it can smoothly enter the inside of the workpiece and play a fixing role, thereby realizing the fixation between the two workpieces.
[0027] Reference Figure 1 , Figure 2 and Figure 5The outer wall of the connecting column 1 is fixedly connected with a fixing pad 13, the inner wall of the connecting column 1 is rotatably connected with a rotating ring 14, the inner wall of the rotating ring 14 is fixedly connected with a gear ring 15, the outer wall of the gear ring 15 is rotatably connected to the inside of the connecting column 1, the inside of the connecting column 1 is rotatably connected with a gear 16, the gear ring 15 meshes with the gear 16, the upper surface of the connecting base 2 is fixedly connected with an extension plate 20, the inside of the gear 16 is fixedly connected with a screw 17, the outer wall of the screw 17 is rotatably connected to the inside of the connecting column 1, the outer wall of the extension plate 20 is slidably connected to the inside of the connecting column 1, a sliding groove 18 is opened inside the extension plate 20, the bottom of the screw 17 is fixedly connected with a limiting plate 19, the outer wall of the limiting plate 19 is slidably connected to the inside of the sliding groove 18, and the outer wall of the screw 17 is threadedly connected to the inside of the extension plate 20;
[0028] Specifically, the driving rotating ring 14 drives the gear ring 15 to rotate inside the connecting column 1. Due to the meshing of the gear ring 15 and the gear 16, multiple gears 16 can rotate synchronously with the rotation of the gear ring 15, which not only improves the operating efficiency of the system, but also enhances its stability, so that multiple screws 17 rotate synchronously with the gear 16, and then push the extension plate 20. Through the threaded relationship between the screw 17 and the extension plate 20, as the screw 17 rotates, the extension plate 20 slides inside the connecting column 1 and moves out from the inside of the connecting column 1, so that the equipment can adapt to workpieces of various thicknesses, greatly broadening its application range.
[0029] Working principle: when the anti-falling weeding machine connection piece is needed, firstly, the connecting column 1 and the connecting base 2 are passed through the workpiece, and then the connecting base 2 is placed inside the workpiece to be connected, and then the handle 4 is pressed to drive the sliding block 5 and the limiting block 6 to slide inside the fixed column 3, and then the limiting block 6 slides in the preset U-shaped slideway inside the fixed column 3, and at the same time, the spring 8 is contracted, and when the limiting block 6 slides to the bottom, the handle 4 is turned to drive the limiting block 6 to slide inside the slideway, and at the same time, the rotating disk 10 is driven to rotate by the telescopic rod 9, and then the handle 4 is released. At this time, the spring 8 is no longer subjected to force and rebounds to push the sliding block 5 to move upward, so that the limiting block 6 is fixed inside the slideway. In this process, the rotation of the rotating disk 10 will drive the card block 11 to slide on the arc-shaped slideway inside the rotating disk 10, so that the card block 11 moves to the inside of the workpiece to be connected, and at the same time, the movement of the card block 11 is guided by the guide plate 12 to achieve fixation between the two workpieces;
[0030] In addition, when encountering workpieces of different thicknesses, the driving rotating ring 14 drives the gear ring 15 to rotate inside the connecting column 1, so that the multiple gears 16 rotate synchronously with the rotation of the gear ring 15, thereby driving the multiple screws 17 to rotate synchronously, and then through the threaded relationship between the screw 17 and the extension plate 20, the extension plate 20 slides inside the connecting column 1 with the rotation of the screw 17, and then the extension plate 20 moves out of the connecting column 1 to achieve the extension effect, so that it can be suitable for workpieces of different thicknesses.
[0031] 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.
