[0020] Specifically, a slide groove 5 is provided on the upper ends of the left and right sides of the C-shaped column 2. The two sets of slide grooves 5 are internally connected with a slide plate 6 for sliding movement. A connecting support 7 is fixedly connected to the upper center position of the slide plate 6, which effectively protects the lower end of the threaded rod 8 and connects the slide plate 6 and the threaded rod 8 at the same time. The internal rotation of the connecting support 7 is connected to the threaded rod 8. The upper end of the threaded rod 8 passes through the lower end of the top beam 4 and is threadedly connected to a fastening nut 9. The lower side of the fastening nut 9 is rotatably connected to the upper side of the top beam 4, which can effectively control the threaded rod 8 and the slide plate 6 to move upward, and effectively tighten the pull rod 15.
[0021] Specifically, the left and right sides of the slide plate 6 are fixedly connected to the inside of the slide groove 5, and the inner side of the connecting member 10 is slidably connected to the outer side of the C-shaped column 2. Bolt holes 11 are opened at the center positions of the front and rear sides of the connecting member 10. High-strength bolts 12 are slidably connected inside the bolt holes 11. The left and right ends of the front and rear sides of the platform plate 1 are rotatably connected to rotating rods 13. The outer side of the rotating rod 13 is fixedly connected to the mounting tube 14. The inside of the mounting tube 14 is slidably connected to a pull rod 15. The lower end of the pull rod 15 is fixedly connected to a stopper 16 to avoid the use of bolts to prevent sliding. The upper end of the pull rod 15 is fixedly connected to a connecting ring 17. The interior is rotatably connected to the surface of the high-strength bolt 12, and a fixing plate 18 is fixedly connected to the middle position inside the C-shaped column 2. The upper side of the fixing plate 18 is fixedly connected to a support rod 19, and the internal sliding connection of the support rod 19 is a sliding connection with a slide rod 20. The upper side of the slide rod 20 is fixedly connected to the lower side of the slide plate 6, and a fixing hole 21 is penetrated at the upper end of the front side of the support rod 19, and a positioning hole 22 is penetrated at the lower end of the front side of the slide rod 20. A fixing bolt 23 is slidably connected to the inside of the fixing hole 21, and the end of the fixing bolt 23 is threadedly connected to the inner wall of the C-shaped column 2, effectively fixing the slide rod 20 and the support rod 19, and transmitting the force exerted on the slide plate 6 to the fixing plate 18 and the C-shaped column 2.
[0022] Working principle: When installing the pull rod 15, pass the pull rod 15 through the mounting tube 14, and place the connecting ring 17 inside the connector 10. The high-strength bolt 12 passes through the bolt hole 11 and the inside of the connecting ring 17 and is fixed. When the pull rod 15 is subjected to force, the thread direction of the high-strength bolt 12 is not subjected to force, completing the connection between the pull rod 15 and the connector 10. Then, turn the fastening nut 9, and the threaded rod 8 drives the slide 6 to move upward. At the same time, the upper end of the pull rod 15 continues to move upward until the stopper 16 abuts against the mounting tube 14 to fix the pull rod 15. As the slide 6 moves upward, the slide bar 20 will also move upward. After the pull rod 15 is fixed, it moves to the fixing hole 21 and the corresponding Insert the fixing bolt 23 into the positioning hole 22, and rotate the fixing bolt 23 so that the end of the fixing bolt 23 is threadedly connected to the inner wall of the C-shaped column 2. When the pull rod 15 is subjected to force, the force will be transmitted to the skateboard 6 through the connecting piece 10, and part of the force applied to the skateboard 6 is transmitted to the threaded rod 8. At the same time, the support rod 19 and the sliding rod 20 can effectively connect the skateboard 6 and the fixed plate 18, and transmit part of the force applied to the skateboard 6 to the C-shaped column 2, effectively reducing the force applied to the threaded rod 8 and protecting the threads on the threaded rod 8. If the threads of the threaded rod 8 are damaged, the sliding rod 20 and the support rod 19 can also fix the position of the skateboard 6 to prevent the pull rod 15 from sliding.
