[0048] Embodiment 2

[0049] See also Figures 1 to 10 The automobile suspension stabilizer bar fixing device shown includes a clamp 1 and an automobile suspension stabilizer bar bushing. The clamp 1 is arranged outside the bushing. The clamp 1 includes a clamp body 11 and a connecting portion 12. The clamp body 11 is U-shaped. A limiting hole 111 is provided on the hoop body 11. Preferably, four limiting holes 111 are provided. The limiting holes 111 are provided on opposite sides of the hoop body 11. When the bushing is connected to the clamp 1, the first protrusion 7 and the second protrusion 8 can be respectively inserted into the limiting holes 111 of the hoop body 11 to limit the movement of the bushing, which is convenient for operation.

The outer diameter of the extension section 14 is smaller than the outer diameter of the hoop body 11, and the outer diameter of the extension section 14 is smaller than the outer diameter of the bushing body. The advantage of providing the extension portion is that when the clamp 1 is connected to the bushing, in the U-shaped space of the hoop body 11, the opposite ends of the bushing along its axial direction respectively correspond to parts of the transition section 13, but one end of the bushing along its axial direction does not extend to an extension section 14, and the other end of the bushing along its axial direction does not extend to another extension section 14. When working, the extension section 14 can block the bushing and restrict the bushing from detaching from the clamp 1.
