Specifically, the outer surface of the connecting block 3 is rotatably connected with a limiting plate 1 and a limiting plate 2. The limiting plate 1 and the limiting plate 2 and the connecting block 3 are set as a rotating connection. When the connecting block 3 moves, the limiting plate 1 and the limiting plate 2 move up and down.

The groove 14 is adapted to the screw rod body 7. The upper surface of the support seat 13 is fixedly installed with an electric push rod 2. The telescopic end of the electric push rod 2 is fixedly connected with a fixed plate 16. The electric push rod 2 is installed on the upper surface of the support seat 13, and the fixed plate 16 is installed at the telescopic end of the electric push rod 2. The support seat 13 fixes the electric push rod 2, and the electric push rod 2 realizes the moving effect of the fixed plate 16.

[0026] In a preferred embodiment, a conveyor belt 8 is installed on the inner wall of the base 9. By installing the conveyor belt 8 on the inner wall of the base 9, the position of the conveyor belt 8 is positioned by the base 9. Three screw rod bodies 7 are placed on the outer surface of the conveyor belt 8. By placing the screw rod bodies 7 on the upper surface of the conveyor belt 8, the screw rod bodies 7 are driven to move by the conveyor belt 8. When the connecting block 3 rotates, it drives the first limiting plate 4 to move upward and drives the second limiting plate 6 to move downward. The screw rod body 7 will move between the first limiting plate 4 and the second limiting plate 6. The connecting block 3 continues to rotate, driving the inclined surface of the first limiting plate 4 to move downward between the two screw rod bodies 7. The subsequent screw rod bodies 7 are limited by the first limiting plate 4, and the second limiting plate 6 is driven to move upward. The screw rod body 7 located between the first limiting plate 4 and the second limiting plate 6 can continue to move, thereby achieving the effect of moving the screw rod body 7 into the groove 14.

[0027] In this embodiment, a support plate 12 is fixedly connected to the upper surface of the base 9. By installing the support plate 12 on the upper surface of the base 9, the support plate 12 is supported by the base 9.

After the screw rod body 7 moves into the groove 14, the fixing plate 16 is driven to move by the second electric push rod 15. The screw rod body 7 can be pushed into the rolling machine through the fixing plate 16, thereby achieving the effect of automatically feeding the screw rod body 7 and also increasing the accuracy of the screw rod body 7 after processing.

[0028] Combined Figure 1 and Figure 2 , a mounting plate 10 is fixedly connected to the upper surface of the base 9. By installing the mounting plate 10 on the upper surface of the base 9, the mounting plate 10 is fixed by the base 9. The outer surface of the fixing block 5 is fixedly connected to the inner wall of the mounting plate 10. The outer surface of the fixing block 5 is connected to the inner wall of the mounting plate 10. The fixing block 5 is fixedly supported by the mounting plate 10. A fixing rod 11 is fixedly connected to the inner wall of the mounting plate 10. By installing the fixing rod 11 on the inner wall of the mounting plate 10, the fixing rod 11 is fixed by the mounting plate 10.

[0029] In a preferred embodiment, the inner wall of the connecting block 3 is rotatably connected to the outer surface of the fixing rod 11. A rotational connection is provided between the connecting block 3 and the fixing rod 11. When the first electric push rod 1 drives the rotating shaft 2 to move, the rotating shaft 2 drives the connecting block 3 to rotate on the surface of the fixing rod 11. The connecting block 3 is limited by the fixing rod 11, and the rotational effect of the connecting block 3 is achieved. The outer surfaces of the first limiting plate 4 and the second limiting plate 6 are both slidably connected to the inner wall of the fixing block 5. The first limiting plate 4 and the second limiting plate 6 are limited by the fixing block 5, so that when the connecting block 3 rotates, it drives the first limiting plate 4 and the second limiting plate 6 to move vertically up and down.

[0030] Such asFigure 3 As shown, a limiting block 17 is fixedly connected to a side surface of the fixing plate 16 away from the base 9. The limiting block 17 is installed on the side surface of the fixing plate 16. When the fixing plate 16 moves, the limiting block 17 is driven to move. The outer surface of the limiting block 17 is slidably connected to the inner wall of the support base 13. The connection between the outer surface of the limiting block 17 and the inner wall of the support base 13 is set as a sliding connection. The fixing plate 16 drives the limiting block 17 to move on the inner wall of the support base 13. The support base 13 limits the limiting block 17, and further limits the fixing plate 16, so that the fixing plate 16 remains stable when moving, and thus it is convenient to stably move the screw rod body 7 into the thread rolling machine through the fixing plate 16.
