[0038] The bottom of the inside of the force arm 362 is provided with a slot, and the inside of the force arm 362 is provided with a rectangular hole;

[0039] And a clamping plate 363 is arranged in the rectangular hole, and the number of the clamping plate 363 is two;

[0040] Two clamping plates 363 are connected with a pull rod 364;

[0041] The inner end of the guide rod 365 is arranged on the pull rod 364.

[0042] When the plurality of fixing assemblies 200 are arranged on the plurality of fixing tube mechanisms 300, the plurality of fixing assemblies 200 can provide protection against foreign object impact and protection against rust and corrosion;

[0043] In addition, the pad layer formed by the anti-seepage bottom pad 310 and the plug pad 320 can provide wear protection for the surface of the auxiliary frame assembly 100, when the nut 220 is attached and locked on the top of the anti-seepage bottom pad 310, the two force arms 362 arranged on both sides of the nut 220 can provide impact protection, and the combined sealing top cover 370 and plug head 380 can seal and protect the exposed threaded section of the bolt 210. Embodiment two

[0044] In combination Figure 2 And Figure 3 As shown in the embodiment 1, two shaft rods 330 are symmetrically arranged on the top of the anti-seepage bottom pad 310, and the two force arms 362 are movably arranged on the two shaft rods 330;

[0045] The bottom of the anti-seepage bottom pad 310 is provided with a rubber layer;

[0046] The plug pad 320 is made of rubber material.

[0047] Preferably, the thickness of the plug pad 320 can be selected according to actual use requirements, which is mainly used to cooperate with the sealing top cover 370 and the two force arms 362 to seal and protect the exposed part of the nut 220;

[0048] In use, the plug head 380 is removed, the lubricating oil is poured through the port on the top of the sealing top cover 370, and then the plug head 380 is re-sealed in the sealing top cover 370, so that the exposed part of the bolt 210 can be protected during actual use. Example 3

[0049] Combine Figure 4-Figure 6 As shown, in the above embodiment, the top surfaces of the ring gasket 361 and the two force arms 362 are provided with an impermeable rubber coating, and the ring gasket 361 and the two force arms 362 are made of stainless steel;

[0050] The pull rod 364 is in a U-shaped structure as a whole. A vertical rod is provided in the groove at the inner end of the clamping plate 363 , and the vertical rod passes through the vertical hole at the end of the pull rod 364 .

[0051] Preferably, the inner end of the guide rod 365 can be movably installed in the column head of the pull rod 364, and a threaded section is provided on the guide rod 365, and the through hole inside the ring gasket 361 is set as a screw hole. By directly adjusting the guide rod 365 to rotate along the screw hole inside the ring gasket 361, the two force arms 362 that are forcibly locked can fix the two side edges of the nut 220.

[0052] The working principle and use process of the present invention are as follows: Since the sub-frame assembly 100 is the skeleton of the axle, it is a bracket that supports the axle and the suspension, so that the axle and the suspension are connected to the main frame through it, and the sub-frame assembly 100 mainly uses a combination of bolts as a fixing part;

[0053] When the sub-frame assembly 100 is fixed to the vehicle frame, the threaded section of the bolt 210 extending from the nut is exposed to the outside environment. To ensure the stability of the sub-frame assembly 100, multiple sets of fixing assemblies 200 are required to fix the sub-frame assembly 100 at multiple points. However, during actual use, this fixing method is affected by external moisture and dirt, causing the exposed threaded section of the bolt 210 to rust and corrode. In severe cases, this can cause the sub-frame assembly 100 to loosen, and the nut 220 to wobble due to the corrosion of the threaded section.

[0054] After the nut 220 is tightened, the plug 320 can be installed in the transverse groove inside the anti-seepage pad 310. Then, the guide rod 365 is released. At this time, the guide rod 365 and the pull rod 364 squeezed by the reinforcing spring 367 will pull the two clamping plates 363 and the two force arms 362. At this time, the two force arms 362 will quickly clamp the nut 220. Finally, the sealing top cover 370 can be stretched again until it returns to its original position. At this time, the cylindrical pipe of the sealing top cover 370 can seal the exposed threaded section of the bolt 210 and seal the plug 380 in the sealing top cover 370.

[0055] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
