This utility model belongs to the technical field of exhaust pipe brackets, specifically relating to a fixing bracket for automotive aftertreatment exhaust pipes. It includes an upper clamping plate and a lower clamping plate, with the lower clamping plate located below the upper clamping plate. Fixing plates are fixed to both sides of the lower end of the upper clamping plate. A spring is installed inside the lower end of the fixing plate, and sliding plates are fixed to both ends of the spring inside the fixing plate. The two sliding plates are slidably connected to the fixing plate, and a locking block is fixed to the opposite end of each sliding plate. Communicating grooves are provided on both sides of the upper end of the lower clamping plate. This utility model connects the spring, sliding plates, and locking blocks via the fixing plates on both sides of the upper clamping plate. The lower clamping plate is connected to a threaded rod and a movable plate via a base plate and side plate. Utilizing the matching relationship between the first inclined surface of the locking block and the second inclined surface of the movable plate, combined with the elasticity of the spring, the upper and lower clamping plates are locked together. The position of the movable plate can be adjusted by rotating the threaded rod, allowing for the clamping and fixing of exhaust pipes of different specifications.
