[0002] In the field of seat processing, armrests are installed on both sides of the seat to improve comfort. The armrests are generally formed by bending straight tubes to form L-shaped curved tube sections. In order to improve comfort and aesthetics, holes are punched on the outer surface of the armrests to facilitate the installation of cushions or other decorative items.

[0003] However, it is relatively easy to drill holes in straight pipes with existing drilling devices, but it is more difficult to drill holes in curved pipes, and it is also difficult to ensure accuracy. Usually, a clamp is used to clamp the curved pipe and then drill the hole. The operation is too complicated, which reduces the drilling efficiency and also causes drilling deviation, affecting the use.

[0004] The reason for this problem is that the existing device has the following process for drilling holes in the bent pipe: the bent pipe is clamped with a clamp, the bent pipe is punched with a drilling device, the clamp is opened after the holes are punched, the position of the bent pipe is adjusted, and then the clamp is continued to be clamped. A bent pipe needs to be repeated many times, resulting in low drilling efficiency, and it is impossible to ensure that the contact surface of the bent pipe is at 90 degrees with the drilling device after adjustment.
