A second adjustment mechanism is provided at one end of the auxiliary connecting cavity 3 close to the angle adjustment mechanism;

[0037] Two auxiliary anti-collision tubes 4 correspond to the auxiliary connecting chambers 3 one by one and are slidably connected, and the second adjustment mechanism is used to adjust the installation length of the auxiliary anti-collision tubes 4 on the auxiliary connecting chambers 3;

[0038] The two connecting plates 5 are used to fix the end of the secondary anti-collision tube 4 away from the secondary connecting cavity 3 on the vehicle door.
