[0038] Then place the lower guard plate of the rear door of the automobile flat on the two positioning components 2, and make the tops of the first support bar 21, the second support bar 22 and the third support bar 23 in the two positioning components 2 all fit the bottom front edge of the lower guard plate of the rear door of the automobile; at the same time, make the tops of the fourth support bar 28 and the fifth support bar 27 in the two positioning components 2 all fit the bottom rear edge of the lower guard plate of the rear door of the automobile; then make the tops of the arc support bar 24, the sixth support bar 25, the seventh support bar 26 and the corner support block 218 all fit the bottom left or right edge of the lower guard plate of the rear door of the automobile.

[0039] At this time, the top outer wall of each limit block 228 is attached to the inner outer wall of the edge at the corresponding position on the lower guard plate of the car's rear door; the tops of the first support block 214 and the second support block 227 are respectively supported on the bottom middle and corner of the lower guard plate of the car's rear door; at the same time, each locating pin located at the bottom of the lower guard plate of the car's rear door is located between the two clamping blocks of a corresponding second two-way buckle mechanism 7, and each buckle piece located at the bottom of the lower guard plate of the car's rear door is located between the two clamping blocks of a corresponding first two-way buckle mechanism 5; the concave cavity located at the bottom corner of the lower guard plate of the car's rear door is located behind the pressure plate of a corresponding one-way buckle mechanism 11.

[0040] Subsequently, the crank handles of each first pull-rope mechanism 6, each second pull-rope mechanism 8 and the third pull-rope mechanism 9 are pulled in turn to drive the two clamping blocks of each first two-way buckle mechanism 5, the two clamping blocks of each second two-way buckle mechanism 7, and the two clamping blocks of each third two-way buckle mechanism 10 to move closer to each other through the corresponding brake lines, and at the same time drive the pressure plate of each one-way buckle mechanism 11 to swing forward; thereby, the two clamping blocks of each second two-way buckle mechanism 7 clamp a corresponding positioning pin, and the two clamping blocks of each first two-way buckle mechanism 5 clamp a corresponding buckle sheet, and the pressure plate of the one-way buckle mechanism 11 is pressed backwards in a corresponding concave cavity, thereby completing the fixation of the lower guard plate of the rear door of the automobile.

[0041] Finally, use the detection pin 12 to pass backward through the installation hole located on the front side of the lower guard plate of the car's rear door and insert it into the positioning block 4 to complete the centering positioning.
