[0024] The upper surface of the gathering block 7 is fixedly connected to an auxiliary structure, the outer surface of the gathering block 7 is fixedly connected to a rotating rod plate 12, the inner surface of the rotating rod plate 12 is rotatably connected to a threaded rod 13, the outer surface of the threaded rod 13 is threadedly connected to a limit plate 14, the outer surface of the limit plate 14 is fixedly connected to a rocker arm tube 4, and the outer surface of the threaded rod 13 is threadedly connected to a fastening sleeve 15.

[0025] As a technical optimization of this utility model, the rocker arm tube 4 is a rectangular tube. A square groove is provided at one end of the rocker arm tube 4 near the converging block 7. The length of the square groove is equal to the length of the extension arm 6. Two rectangular grooves are provided on the inner wall of the square groove. A locking block 5 is slidably connected to the inner wall of the rectangular groove.

[0026] In this embodiment: the rocker arm tube 4 is used to connect the main structure of the device and limit the range of motion of the extension arm 6. The spacing of the rectangular grooves inside the rocker arm tube 4 is narrower as it gets closer to the receiving block 7, so as to avoid the problem that the extension arm 6 may affect the overall strength of the device after it extends too long.

[0027] As a technical optimization of this utility model, locking blocks 5 are fixedly connected to the outer surfaces of both sides of the extension arm 6, and the length of the extension arm 6 is one-third of the total length of the rocker arm tube 4.

[0028] In this embodiment: the extension arm 6 is used to extend the length of the device to a certain extent, thereby adapting to different modified vehicle models.

[0029] As a technical optimization of this utility model, the fixing block 8 is two rectangular plates of equal thickness. The two fixing blocks 8 are fixedly connected to the two side converging blocks 7 respectively. The outer surface of the two fixing blocks 8 is provided with rectangular holes of equal length and width.

[0030] In this embodiment: the fixing block 8 is used to facilitate fixing the device to the vehicle.

[0031] As a technical optimization of this utility model, the auxiliary fixing structure includes a lifting bushing 9, an auxiliary rotating shaft 10, and a steering plate 11. A gathering block 7 is fixedly connected to the lower surface of the lifting bushing 9, the auxiliary rotating shaft 10 is fixedly connected to the inner surface of the lifting bushing 9, and the steering plate 11 is rotatably connected to the outer circumferential surface of the auxiliary rotating shaft 10.

[0032] In this embodiment: the reinforcement structure is used to provide a better environment for the connection between the device and the shock absorber connecting plate.

[0033] As a technical optimization of this utility model, the directional plate 11 is an I-shaped plate, and two rounded corner plates are provided at one end of the directional plate 11. A through hole is provided at the center of the rounded corner plate, and the diameter of the through hole is the same as the diameter of the auxiliary rotating shaft 10.

Then, the threaded rods 13 on both sides are rotated according to the distance from the middle section structure of the pedal to the rear wheel of the pedal. This causes the threaded rods 13 to rotate and push a part of the extension arm 6 outward, thereby extending the overall length of the device. Then, the fastening sleeve 15 is fixed on the threaded rod 13 to lock the threaded rod 13 and prevent the threaded rod 13 from rotating on its own. Then, the angle of the adjusting plate 11 is adjusted, and then the adjusting plate 11 is fixed to the shock absorber connecting plate to avoid the problem that the irregular shock absorber connecting plate part of the structure cannot be connected to the device.
