[0002] Currently, there are usually two ways to fix the spoiler of a passenger car to the tailgate sheet metal. The first is to use a combination of bolts and nuts, that is, the bolts are fixed to the spoiler assembly, and the nuts are used to fix the spoiler when it is installed. The second is to use a conical clip to assist in fixing, that is, the conical clip is installed on the spoiler assembly, and the spoiler is fixed to the tailgate sheet metal together with the clip when it is installed.

[0003] The first type of nut has the best fixing firmness, but the disadvantage is that the installation process is time-consuming, and when there are many spoiler installation points, the labor cost of all screw connections is too high, so it is usually necessary to use it with a ferrule or buckle for auxiliary fixing. The second type of conical buckle is used as an auxiliary fixation, but the disadvantage is that the buckle or spoiler mounting seat is easy to break during disassembly, and the waterproof tongue will age over time and the vibration of the vehicle will cause the waterproof performance to deteriorate. In addition, since the blow-molded spoiler cannot provide an installation structure, it cannot be used in the spoiler of the blow-molded process.

[0053] When in use, first place the mounting base 201 on the upper end of the mounting base 101, and ensure that the elliptical through hole 201b is matched with the mounting hole 101e. At this time, the mounting column 202 is placed into the mounting tube 101c through the mounting hole 101e. When the mounting column 202 is fully extended into the mounting tube 101c, rotate the mounting column 202 counterclockwise to make the locking plate 202c and the mounting plate 101d gradually intersect. In this process, the sliding block 203b will slide into the reducing circular groove 201c-1 as the rotating process. When the locking plate 202c and the mounting plate 101d are completely intersected, that is, after rotating ninety degrees, the sliding block 203b enters the limiting groove 201c-2 under the pull of the block spring 203a, so that the movement of the mounting column 202 in all directions is restricted, and the installation process is completed.
