A tail pipe (40) of an automobile exhaust pipe comprises a pipe body (41), multiple clamping leaf springs (43) and multiple self-locking leaf springs (44). The pipe body is provided with an inlet end (41a) that is sleeved on an outer wall of a tail end of the exhaust pipe and an outlet end (41b) opposite to the inlet end. The multiple clamping leaf springs are arranged on an inner wall of the pipe body, and each clamping leaf spring is provided with a fixing part (43a) that is fixed on the inner wall of the pipe body and a clamping part (43c) that is used for pressing against the outer wall of the exhaust pipe. The multiple self-locking leaf springs are arranged on the inner wall of the pipe body, and each self-locking leaf spring is provided with a fixing part (44a) that is fixed on the inner wall of the pipe body and a withstanding part (44b) that points to the outlet end of the pipe body aslant, wherein the withstanding part is used for pressing against a step of the exhaust pipe that is sleeved in so as to prevent the inlet end from being detached from the tail end of the exhaust pipe, wherein the clamping part is located in a first area of the inner wall of the pipe body, the withstanding part is located in a second area of the inner wall of the pipe body and the second area is closer to the inlet end of the pipe body than the first area. After the tail pipe using a preceding structure is sleeved on the tail end of the exhaust pipe, the inlet end of the tail pipe can be prevented from being detached from the tail end of the exhaust pipe, thus effectively preventing the tail pipe from loosening and falling off, and fulfilling a function of self-locking of the tail pipe. |
