[0011] The utility model has the following beneficial effects:

[0012] (1) The utility model uses a threaded column and a rotating rod 2 to rotate the fixing frame 1 and the fixing frame 2 around the positioning axis, so that the arc-shaped clamping block moves outward and contacts the inner wall of the mounting hole, thereby achieving the purpose of installing the automobile wheel eyebrow. Although some threads are used to control the upward and downward movement of the threaded column 1 and the threaded column 2, due to the influence of the depth of the mounting hole, it does not need to rotate a large number of times, thereby achieving the effect of quick installation and disassembly.

[0013] (2) The utility model uses special-shaped connecting plates, and the special-shaped connecting plates located at the upper and lower ends can be extended and retracted over a certain distance through the cylinder, so that the entire structure will not be stuck and unable to move during operation. Through the arc-shaped clamping block, the bottom of the arc-shaped clamping block will contact the top of the threaded column one when it is in the retracted state, and its outer diameter is smaller than the diameter of the threaded column one, so the threaded column one will not be stuck when it is deeply inserted into the installation hole.
