[0035] Specifically, the nailing assembly 3 and the nail pushing assembly 4 are fixed to the base 1 by bolts to form a nail gun auxiliary mechanism. The nailing assembly 2 is arranged in cooperation with the nailing assembly 3 and the nail pushing assembly 4 through a manipulator (not shown in the attached figure). The manipulator and the nailing assembly 2 connected thereto can be used in cooperation with multiple nail gun auxiliary mechanisms to achieve nailing at multiple positions and improve nailing efficiency. In order to reduce the nailing frequency and improve the nailing efficiency, the nail storage box 31 can be loaded with multiple groups of n-shaped nail rows 5. A nail dropping plate 32 is provided below the nail storage box 31. The nail feeding mechanism 33 pushes the n-shaped nail row 5 on the nail dropping plate 32 into the nail groove 24 in the horizontal direction. After the nail feeding mechanism 33 is reset, the n-shaped nail row 5 falls on the nail dropping plate 32 under the action of gravity, completing one nailing. After nailing is completed, the push nail plate 41 is driven by the driving part 42 to slide along the nail groove 24, and the n-shaped nail row 5 on the nail groove 24 is sequentially sent into the nailing assembly 2. The guide part 43 can improve the smoothness of the movement of the n-shaped nail row 5.
