[0011] Preferably, a placement groove is provided inside the base, and the inside of the placement groove is rotatably connected to the bottom of the rotating rod.

The fixing block 17 is provided with a limit plate 18 at one end thereof, and a contact block 19 is fixed to one end of the limit plate 18. A base 20 is fixed inside the fixing block 17, and a rotating rod 21 is connected to the inside of the base 20, and a knob 22 is fixed to the top of the rotating rod 21. By pressing the protrusion 13, the moving block 12 is driven to slide inside the groove 11, and the spring 14 begins to shrink. Then, the product to be screwed is placed on the material moving platform 7, and the product is abutted against the threaded rod 9 and the second fixing frame 10. Then, the protrusion 13 is released, and the rebound force of the spring 14 is used to push the moving block 12 to initially fix the product. Then, the limiting plate 18 is rotated to drive the contact block 19 to fix the top of the product, thereby improving the stability of the product, achieving precise positioning, and ensuring that the screw can enter the screw hole accurately and without deviation. Through the flexibility of the above structure, it can be adjusted and customized according to the shape and screw hole position of different products, thereby improving the practicality of the equipment.

[0022] Reference Figure 2 As shown, in this embodiment: slide grooves 15 are provided on both sides of the groove 11, and a slider 16 is slidably connected inside the slide groove 15, and one end of the slider 16 is fixed to the moving block 12. By setting the structure of the slide groove 15 and the slider 16, the moving trajectory of the moving block 12 can be restricted to avoid tilting.

[0023] Reference Figure 3 and Figure 4 As shown, in this embodiment: the surface of the rotating rod 21 is rotatably connected to the limiting block 23. By setting the limiting block 23, the position of the rotating rod 21 can be limited to avoid shaking when the knob 22 locks the limiting plate 18.

[0024] Reference Figure 4 As shown, in this embodiment: a limiting groove 25 for use with the limiting block 23 is opened on the surface of the limiting plate 18. By setting the limiting groove 25, it can be used in conjunction with the limiting block 23 to improve the locking effect of the knob 22.

[0027] Working principle: the user presses the convex block 13 to drive the moving block 12 to slide inside the groove 11, and the spring 14 begins to contract. Then the product to be screwed is placed on the material moving platform 7, and the product is abutted against the threaded rod 9 and the second fixing frame 10. Then the convex block 13 is released, and the rebound force of the spring 14 is used to push the moving block 12 to initially fix the product. Then the limiting plate 18 is rotated to drive the abutment block 19 to fix the top of the product, thereby improving the stability of the product and achieving precise positioning, ensuring that the screw can enter the screw hole accurately and without deviation. Through the flexibility of the above structure, it can be adjusted according to the shape and position of the screw hole of different products. Adjustment and customization can improve the practicality of the equipment. By setting the structure of the slide groove 15 and the slider 16, the moving trajectory of the moving block 12 can be limited to avoid tilting. By setting the limit block 23, the position of the rotating rod 21 can be limited to avoid shaking when the knob 22 locks the limit plate 18. By setting the limit groove 25, it can be used in conjunction with the limit block 23 to improve the locking effect of the knob 22. By setting the placement groove 24, the bottom end of the rotating rod 21 can be supported and limited. By setting the rubber pad 26, the friction between the abutment block 19 and the product to be screwed can be increased to improve stability.
