The invention discloses a quick positioning mechanism for an L-shaped small part. The quick positioning mechanism comprises a first compressing mechanism, a second compressing mechanism and a positioning pin. The first compressing mechanism comprises a first air cylinder, a first linkage mechanism and a first pressing block, the first air cylinder controls the first pressing block to conduct lifting displacement through the first linkage mechanism, the first pressing block presses a vehicle body large part, and a storing plate is arranged below the vehicle body large part. The second compressing mechanism comprises a second air cylinder, a second linkage mechanism and second pressing blocks, the second air cylinder controls the second pressing blocks to move in the left-right direction through the second linkage mechanism, and a through hole allowing the positioning pin to be inserted into is formed in the side end of the storing plate. The L-shaped small part is placed in the throughhole and fixed through th
