[0023] The present invention will be further described below with reference to specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, a bidirectional adjustment device for fastening a tractor in this embodiment includes a connecting seat 1. Movable plates 2 are provided on both sides of the connecting seat 1. Second movable grooves 20 are recessed on both sides of the connecting seat 1 facing the upper and lower ends of the movable plates 2, and a connecting rod 19 is provided inside the second movable groove 20. The connecting rod 19 is welded and fixed to the movable plate 2. The distance between the movable plate 2 and the connecting seat 1 can be adjusted by moving the connecting rod 19 in the second movable groove 20.

[0025] In this embodiment, the installation requirements of the installation position can be directly adapted by adjusting the position of the movable plate 2. The position adjustment of the movable plate 2 corresponds to the first adjustment. The front end of the second movable groove 20 is provided with a first movable groove 3, and the first movable groove 3 passes through the connecting seat 1 and extends to the front end of the connecting seat 1. The reserved first movable groove 3 facilitates the fixing of the connecting rod 19 and the movable plate 2, and assists in further fixing the position of the movable plate 2. The interior of the first movable groove 3 is provided with a second bolt 14. The connecting rod 19 is recessed towards the position of the first movable groove 3 and is provided with a fourth mounting hole 21. The fourth mounting hole 21 is threadedly engaged with the second bolt 14. By rotating the position of the second bolt 14, it can be inserted into the interior of the fourth mounting hole 21. With the rotation of the second bolt 14, it can finally fit against the connecting seat 1, and assist in fixing the position of the connecting rod 19 after its movement.

[0026] Furthermore, such as Figure 6 As shown, strip-shaped first anti-slip strips 4 are provided at both the upper and lower ends of the outer surface of the first movable groove 3. The first anti-slip strips 4 are made of rubber. The reserved first anti-slip strips 4 facilitate the second bolt 14 to adhere and increase friction after rotation, thereby improving the ability of the second bolt 14 to fix the connecting rod 19 and enhancing the stability of the fixed connecting rod 19. First mounting holes 11 are provided at both the upper and lower ends of the interior of the movable plate 2 and on both sides of the interior of the connecting seat 1. Figure 4 and Figure 5 As shown, a first bolt 13 is provided inside the first mounting hole 11. The reserved first mounting hole 11 facilitates the passage of the first bolt 13, allowing the first bolt 13 to pass through the first mounting hole 11 and fix the movable plate 2 and the connecting seat 1 respectively.

[0027] To adjust the position of the connecting cylinder 10 at the front end of the connecting seat 1, the front ends of the two connecting seats 1 are provided with first fixing seats 5, which are welded and fixed to the connecting seats 1. The two first fixing seats 5 are evenly distributed with mounting grooves 8 on the outside. The upper end of the outside of the mounting groove 8 is provided with a connecting strip 9, and the outside of the connecting strip 9 is connected to the internal slot of the mounting groove 8. The upper end of the connecting strip 9 is provided with a second fixing seat 7 on the outside. The second fixing seat 7 can be slidably installed into the mounting groove 8 through the connecting strip 9. The connecting strip 9 can be slid into the corresponding mounting groove 8 to adjust the installation position of the subsequent connecting cylinder 10 to adapt to different traction requirements and achieve a second adjustment. The two adjustments adapt to different suspension requirements.

[0028] It is worth mentioning that a third mounting hole 18 is provided on one side of the upper end of the mounting groove 8, and the third mounting hole 18 is recessed inside the first fixing seat 5. The recessed third mounting hole 18 facilitates the fixing of the second fixing seat 7. A second mounting hole 12 is provided on one side of the connecting strip 9, and the second mounting hole 12 passes through the upper and lower ends of the second fixing seat 7. A third bolt 15 is provided inside the second mounting hole 12, and the outside of the third bolt 15 is engaged with the internal thread of the third mounting hole 18. After the connecting strip 9 slides into the mounting groove 8, the upper ends of the second mounting hole 12 and the third mounting hole 18 overlap, and the second fixing seat 7 can be finally fixed by rotating and embedding the third bolt 15. After adaptation and adjustment, it can be fixed to adapt to different suspension requirements.

[0029] Furthermore, a fifth mounting hole 22 is provided on the other side of the second mounting hole 12, and the fifth mounting hole 22 passes through the upper and lower ends of the second fixed base 7. A connecting tube 10 is provided between the two fifth mounting holes 22. The suspended connection position is restricted by the connecting tube 10, and the connecting tube 10 contacts the pulled position.

[0030] like Figure 3 As shown, a fourth bolt 17 is installed through the interior of the connecting cylinder 10, and the fourth bolt 17 passes through the two second fixing seats 7 and the interior of the connecting cylinder 10 to fix the connecting cylinder 10. A nut is provided at the lower end of the outer side of the fourth bolt 17. After the fourth bolt 17 passes through, the nut is rotated to fix the fourth bolt 17 and the connecting cylinder 10. The fixing method is simple, easy to disassemble, and convenient for replacement and maintenance.

[0031] To improve the stability of the connection between the two first fixed seats 5, a sheet-like reinforcing strip 6 is provided between the two first fixed seats 5, and the reinforcing strip 6 is welded and fixed to the first fixed seat 5. The welding and fixing of the first fixed seat 5 and the reinforcing strip 6 can improve the load-bearing capacity of the entire tractor fastening bidirectional adjustment device and avoid deformation and bending during pulling.

[0032] In this embodiment, a second anti-slip strip 16 is provided laterally at the rear end of the connecting seat 1 and the movable plate 2. The second anti-slip strip 16 is fixed to the connecting seat 1 and the movable plate 2 respectively with glue. The material of the second anti-slip strip 16 is rubber. The second anti-slip strip 16 made of rubber can fix the connecting seat 1 in the traction position, which can improve the stability of the connection between the connecting seat 1 and the movable plate 2 and the tractor.

[0033] Working principle: When using the device and making connections, it can be adjusted in both directions to adapt to different connection requirements. The first bolt 13 passes through the first mounting hole 11 inside the connecting seat 1 and is embedded in the mounting position to fix the position of the tractor. The movable plate 2 slides laterally. The movable plate 2 slides in the second movable groove 20 through the connecting rod 19, and slides and adjusts the distance between the movable plate 2 and the connecting seat 1. After the distance is adjusted, the first bolt 13 passes through the first mounting hole 11 inside the movable plate 2 to fix the movable plate 2. After rotating the second bolt 14 into the first movable groove 3, the second bolt 14 is rotated into the fourth mounting hole 21. The continuous rotation of the second bolt 14... Position the first anti-slip strips 4 at both ends of the first movable groove 3. The second fixed seat 7 slides into the mounting groove 8 through the connecting strip 9. The third bolt 15 penetrates the second mounting hole 12 and is embedded in the corresponding third mounting hole 18 at the lower end to fix the first fixed seat 5. Place the connecting cylinder 10 between the two second fixed seats 7. The fourth bolt 17 penetrates the two fifth mounting holes 22 and passes through the connecting cylinder 10 at the same time. After passing through the fourth bolt 17, rotate the nut to the outside of the fourth bolt 17 to fix the connecting cylinder 10. Place the item to be pulled between the reinforcing strip 6, the pair of second fixed seats 7 and the connecting cylinder 10 to achieve bidirectional adjustment and complete the traction.
