[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4A suction nozzle for an automatic screw locking machine comprises a pipe body 1, one side of the pipe body 1 is connected to a vacuum tube 2, a rubber sealing ring 3 is arranged on the inner wall of the pipe body 1, the pipe body 1 is cylindrical with openings at both ends, a mounting hole is arranged on one side of the outer wall of the pipe body 1, the vacuum tube 2 is fixedly connected to the mounting hole, and is connected to a vacuum source through the vacuum tube 2, and screws are adsorbed by vacuum suction to ensure that the screws remain stable during adsorption and transportation;

[0021] The bottom end of the pipeline body 1 is connected to the first telescopic tube 4, and an adjusting seat 8 is provided on one side of the outer wall of the first telescopic tube 4. The adjusting seat 8 is threadedly connected to the adjusting rod 7. An adjusting ring 6 is provided on the outer wall of the second telescopic tube 5. The adjusting ring 6 is in a circular ring shape, and a cross-shaped mounting end is provided on the outer wall of the adjusting ring 6. The cross-shaped mounting end is provided with a threaded hole. There are four adjusting rods 7. The upper and lower ends of the four adjusting rods 7 are respectively threadedly connected to the threaded holes of the adjusting seat 8 and the adjusting ring 6. After the first telescopic tube 4, the second telescopic tube 5 and the third telescopic tube 9 are folded together, the four adjusting seats 8 and the adjusting ring 6 are respectively threaded together through the four adjusting rods 7 to ensure that the telescopic tubes will not accidentally slide or stretch during use and maintain a stable state.

[0022] The inner wall diameter of the second telescopic tube 5 matches the outer wall diameter of the first telescopic tube 4, and the inner wall diameter of the third telescopic tube 9 matches the outer wall diameter of the second telescopic tube 5. The second telescopic tube 5 can be slid up and down on the outer wall of the first telescopic tube 4, and the third telescopic tube 9 can be slid up and down on the outer wall of the second telescopic tube 5. When the first telescopic tube 4, the second telescopic tube 5 and the third telescopic tube 9 are fully unfolded up and down, an extended tubular structure is formed, thereby expanding the size of the opening end of the suction nozzle body. By expanding the size of the opening end, the effective area of ​​the vacuum suction can be increased, thereby improving the ability to adsorb screws;
