[0036] Specifically, as Figures 1-4 shown, in the embodiment, the outer locking mechanism 3 and the telescopic driving mechanism 4 are arranged on the fixed plate 1, and the fixed plate 1 is connected to an external moving device such as a mechanical hand; the inner locking mechanism 2 is arranged on the telescopic driving mechanism 4, and the output end of the inner locking mechanism 2 is arranged in the output end of the outer locking mechanism 3, and the telescopic driving mechanism 4 drives the output end of the inner locking mechanism 2 to telescope in the output end of the outer locking mechanism 3; the inner locking mechanism 2 is used for locking a top screw on a product, and the outer locking mechanism 3 is used for locking a nut on the top screw, so that the top screw and the nut can be independently locked, and one device can realize automatic locking of the top screw and the nut, which is simple to operate and high in efficiency.

[0037] Specifically, as Figures 1-4 shown, in the embodiment, the telescopic driving mechanism 4 comprises a cylinder 41 and a guide rail 42; the cylinder 41 and the guide rail 42 are both fixed on the fixed plate 1; the cylinder 41 is connected to the inner locking mechanism 2, and the guide rail 42 is slidingly connected to the inner locking mechanism 2, the cylinder 41 drives the inner locking mechanism 2 to slide up and down along the guide rail 42, and the guide rail 42 provides linear guidance for the inner locking mechanism 2, so that the inner locking mechanism 2 can keep stable during the up and down movement and the stability of locking is improved.

[0038] Further, as Figures 1-4As shown, in this embodiment, the inner locking mechanism 2 includes: a mounting plate 21, an electric screwdriver 22, and a hexagonal rod 23; the mounting plate 21 is connected to the telescopic drive mechanism 4; the electric screwdriver 22 is fixed on the mounting plate 21; the hexagonal rod 23 is connected to the output end of the electric screwdriver 22 and is disposed within the output end of the outer locking mechanism 3; the telescopic drive mechanism 4 drives the hexagonal rod 23 to insert into the set screw hole of the set screw, and the electric screwdriver 22 drives the hexagonal rod 23 to rotate, thereby locking the set screw.

[0039] Furthermore, such as Figures 1-4 As shown, in this embodiment, a limiting member 24 is fixedly sleeved on the hexagonal rod 23. The limiting member 24 limits the extension length of the hexagonal rod 23. The limiting member 24 is an annular limiting block. The limiting member 24 prevents the hexagonal rod 23 from being over-inserted into the set screw, ensuring that the depth of the hexagonal rod 23 inserted into the set screw hole is consistent during the locking process, thereby improving the quality and reliability of the locking and reducing the defect rate.

[0040] Furthermore, such as Figures 1-4 As shown, in this embodiment, the external locking mechanism 3 includes a driving component 31, a transmission assembly, and a hexagonal sleeve 32.
