[0006] The connecting device comprises a partition fixedly mounted on the pipe body of the intake pipe, the pipe body of the intake pipe is provided with a connecting assembly for threaded connection with a turbocharger connecting pipe, and the connecting assembly rotates on the pipe body of the intake pipe.

[0007] Furthermore, there are two baffles, and the two baffles are symmetrically distributed on both sides of the connecting assembly to prevent the connecting assembly from falling off the pipe body of the air intake pipe.

[0008] Furthermore, the connecting assembly includes a rotating cover which is sleeved on the tube body of the intake pipe for rotation, and the rotating cover can move along the tube body of the intake pipe between the two partitions, and a threaded groove for threaded connection with the turbocharger connecting pipe is provided on the inner wall of the rotating cover.

[0009] Furthermore, a placement groove for inserting and tightening the intake pipe is opened at the left end of the turbocharger connecting pipe, an elastic member for fixing the intake pipe is fixedly installed on the inner wall of the placement groove, and an external thread for threaded connection with the thread groove is fixedly installed on the pipe body of the turbocharger connecting pipe.

[0010] Furthermore, a groove for the elastic member to clamp is formed on the pipe body of the intake pipe at one end close to the turbocharger connecting pipe, and there are two grooves.

[0011] Furthermore, a connecting block is fixedly mounted on the pipe body of the air inlet pipe, and there are two connecting blocks, and the connecting blocks are located on a side away from the partition.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
