[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1-5 The guide arm for air suspension shown in the figure includes a screw 15, a screw 15 is welded to the bottom of one end of the guide arm body 6, a support plate 2 is provided below the screw 15, a second long hole 9 is provided on the surface of the support plate 2, the second long hole 9 is sleeved on the surface of the screw 15, two first long holes 3 are provided on the surface of the support plate 2, the two first long holes 3 are symmetrically arranged on both sides of the second long hole 9, the second long hole 9 and the first long hole 3 have the same length, the surface of the second long hole 9 and the surface of the support plate 2 are arranged on the same center line, so that the position of the support plate 2 can be limited by the rack 10 and the tooth block 13 after horizontal movement and adjustment. The support plate 2 can not only rotate on the surface of the screw rod 15 by using the second elongated hole 9, but also slide on the surface of the screw rod 15 through the second elongated hole 9, which is used to adjust the distance between the support plate 2 and the guide arm according to the limitation of the installation space. The specific operation is to first rotate the fastening nut 7, and the fastening nut 7 is threadedly rotated on the screw rod 15. After the fastening nut 7 is away from the baffle plate 4, the baffle plate 4 slides on the surface of the screw rod 15, and the baffle plate 4 drives the mounting plate 12 to move synchronously, and the mounting plate 12 drives the tooth block 13 to move out of the rack 10, so that a force can be applied to the support plate 2, and the support plate 2 moves on the surface of the screw rod 15 through the second elongated hole 9. After the length between the support plate 2 and the guide arm is adjusted, the fastening nut 7 can be rotated in the opposite direction, and the fastening nut 7 pushes the baffle plate 4 to move to the bottom of the support plate 2. At the same time, the baffle plate 4 drives the tooth block 13 to be clamped in the tooth groove of the rack 10 through the mounting plate 12, which is used to limit the support plate 2.

[0020] The surface of the screw 15 is sleeved with a baffle 4, and the two ends of the baffle 4 extend to the bottom of the two first long holes 3. The two symmetrical sides of the two second long holes 9 are both installed with racks 10 by screws. The surface of the baffle 4 is installed with mounting plates 12 by screws. The two mounting plates 12 are respectively inserted into the inside of the two first long holes 3. The sides of the two mounting plates 12 are installed with tooth blocks 13 by screws. The two tooth blocks 13 are respectively inserted into the tooth grooves of the two racks 10. The surface of the screw 15 is sleeved with a fastening nut 7, and the end of the fastening nut 7 is fixed to the baffle. 4, when adjusting the angle between the support plate 2 and the guide arm, only a force needs to be applied to the support plate 2, and the support plate 2 rotates on the surface of the screw rod 15 through the second long block 9. After the angle adjustment between the support plate 2 and the guide arm is completed, the fastening nut 7 can be rotated, and the fastening nut 7 is threadedly rotated on the surface of the screw rod 15, and the fastening nut 7 pushes the baffle plate 4, and the baffle plate 4 moves on the surface of the screw rod 15. After the baffle plate 4 pushes the support plate 2 to contact the bottom of the disc 5, the fastening nut 7 can be stopped to fix the position of the support plate 2.

[0021] The baffle plate 4 and the disc 5 are connected by a limiting mechanism. The limiting mechanism includes the disc 5, two second screw holes 11 and two third screw holes 16. The disc 5 is fixedly sleeved on the surface of the screw rod 15. A plurality of first screw holes 14 are provided on the surface of the disc 5. The two second screw holes 11 are respectively provided on the support plate 2. The two third screw holes 16 are provided at both ends of the baffle plate 4. The first screw holes 14, the second screw holes 11 and the third screw holes 16 are located in corresponding positions. A stud 8 is threadedly installed between the first screw holes 14, the second screw holes 11 and the third screw holes 16. There are at least eighteen first screw holes 14, and the eighteen first screw holes 14 are arranged at equal angles. In order to further ensure the stability of the connection between the support plate 2 and the guide arm, after the angle adjustment of the support plate 2 is completed, the positions of the first screw hole 14, the second screw hole 11 and the third screw hole 16 correspond. After the stud 8 is threadedly connected to the first screw hole 14, the second screw hole 11 and the third screw hole 16, it is used to connect the support plate 2 before the baffle 4 and the disc 5, thereby supporting the support plate 2.

[0022] The surface of the support plate 2 is provided with a plurality of tooling holes 1, at least two of which are symmetrically arranged. When the air spring and the support plate 2 are connected, screws are only required to be threadedly installed in the air spring through the tooling holes 1 to fix the air spring and the support plate 2 together.
