The lower wall of the fixing groove has at least two sets of evenly distributed through grooves facing outwards. The upper part of the fixing groove has a fixing notch facing outwards. The lower end of the fixing notch has a limiting plate facing upwards. The inner side of the limiting plate has threads, and the outer side is connected to an anti-slip textured plate through an elastic pad. An adjusting plate is provided in the fixing groove. The outer periphery of the adjusting plate has a retaining plate that extends into the through groove. The middle of the adjusting plate has a round hole through which a positioning rod passes. The upper part of the positioning rod has threads for connecting to the limiting plate, and the lower end of the positioning rod has a baffle for limiting the adjusting plate.

[0006] A further improvement of this utility model for a fastening bolt for an automobile chassis is that the fixing notch and the limiting plate are provided in at least three sets, which are evenly distributed on the upper part of the fixing groove.

[0007] A further improvement of this utility model for a fastening bolt for an automobile chassis is that a groove is provided downward in the middle of the upper end face of the bolt end, and a positioning groove is provided downward in the middle of the groove. The positioning groove is connected to the fixing groove. An adjusting rod passes through the positioning groove. The adjusting rod is threaded. The upper end face of the positioning plate is provided with a threaded groove downward. The adjusting rod is screwed into the threaded groove.

[0008] A further improvement of this utility model for a fastening bolt for an automobile chassis is that a horizontal plate is provided at the upper end of the adjusting rod, and the horizontal plate is placed in the groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention uses an adjusting plate and a locking plate to limit the position of the screwed nut, preventing it from loosening and ensuring the stability of the bolt connection. At the same time, the adjusting rod also presses against the limiting plate to tighten the fastened object, which indirectly improves the connection stability. Attached Figure Description

[0013] In the diagram: 1 Bolt end, 2 Bolt shank, 3 Through groove, 4 Fixing notch, 5 Limiting plate, 6 Adjusting plate, 7 Clamping plate, 8 Positioning rod, 9 Baffle, 10 Threaded groove, 11 Groove, 12 Positioning groove. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 and Figure 2 As shown, a fastening bolt for an automobile chassis includes an integrally formed bolt end 1 and bolt shank 2. The lower end face of the bolt shank has an upward-facing fixing groove. The lower part of the groove wall of the fixing groove has at least two sets of evenly distributed through grooves 3. The upper part of the fixing groove has an outward-facing fixing notch 4. The lower end of the fixing notch has an upward-facing limiting plate 5. The inner side of the limiting plate has threads, and the outer side is connected to an anti-slip textured plate through an elastic pad. An adjusting plate 6 is provided in the fixing groove. The outer periphery of the adjusting plate has a retaining plate 7 that extends into the through groove. The middle of the adjusting plate has a round hole through which a positioning rod 8 passes. The upper part of the positioning rod has threads for connecting to the limiting plate, and the lower end of the positioning rod has a baffle 9 for limiting the adjusting plate.

[0016] The fixed notch and limiting plate are provided in at least three sets, which are evenly distributed on the upper part of the fixed groove.

[0017] Furthermore, a groove 11 is provided downward in the middle of the upper end face of the bolt, and a positioning groove 12 is provided downward in the middle of the groove. The positioning groove connects to the fixing groove, and an adjusting rod passes through the positioning groove.
