[0002] The car muffler is a part used to reduce the noise generated by the engine of a motor vehicle. Since the difference in the length of the two pipes is equal to half the wavelength of the sound waves emitted by the car, the two sound waves interfere with each other when superimposed and cancel each other out, thereby reducing the sound intensity and reducing the sound, thus achieving a muffler effect. At present, most car mufflers are installed and fixed by hooks. The muffler hooks are generally made of metal materials such as steel or aluminum, which have high strength and corrosion resistance. They are usually connected to the chassis of the car by welding or other fixing methods, and need to be checked regularly to ensure that they are firm and reliable to prevent the muffler from shifting or falling off due to looseness or damage.

[0003] For example, the prior art publication number is CN207809049U, which is a muffler hook assembly. The utility model has a simple structure and a simple positioning tooling, can firmly fix the muffler pipeline, and can effectively reduce the vibration transmitted from the muffler pipeline to the vehicle body.

[0004] However, the above-mentioned prior art still has the following problems when in use: since the internal size of the bracket remains unchanged, when placing automobile muffler pipes of different sizes, the staff needs to disassemble the bracket, and then select the corresponding bracket and reinstall it for use, which not only wastes time, but also requires the design of brackets of various specifications, thereby increasing the cost of use. Based on this, the utility model provides an automobile muffler hook with good applicability using a cold heading process. Utility Model Content
