[0012] According to an embodiment of the present application, the tail portion of the external thread is provided with a first guide surface, and the first guide surface is used to guide the edge of the body panel to be in contact with the upper surface of the elastic arm; since the elastic arm is suspended on the fixing support, there is a gap between the free end of the elastic arm and the fixing support, and the first guide surface is arranged to avoid the edge of the body panel from being clamped into the gap.
[0013] According to an embodiment of the present application, the elastic arm has a second guide surface, and the second guide surface is used to guide the elastic arm to be clamped into the limiting portion; the second guide surface is used to provide an additional guiding function during the installation of the anti-collision buffer block, so as to ensure that the elastic arm can be accurately and stably clamped into the limiting portion on the body panel. When the user installs the fixing support, the elastic arm can automatically adjust the position during the rotation and insertion process through the guidance of the second guide surface, thereby reducing the jamming or instability phenomenon caused by errors or improper installation.
[0014] According to an embodiment of the present application, the top end of the second guide surface is flush with the extension surface of the first guide surface.
[0015] According to an embodiment of the present application, the inclination of the first guide surface is greater than the helix angle of the external thread.
