[0033] The locking assembly comprises a limiting plate 7 and a tooth block 8, one side of the tooth block 8 is fixedly connected to one side of the limiting plate 7, through the meshing effect of the tooth block 8, the position of the sliding block 6 inside the positioning frame 2 can be accurately locked, the limiting plate 7 is symmetrically arranged and is slidingly connected inside the sliding block 6, through the symmetric design, the stable movement of the sliding block 6 is ensured, the tooth block 8 is slidingly connected inside the sliding block 6 and is embedded with the tooth block 5 in the positioning assembly, one side of the tooth block 5 is linearly arranged and fixedly connected inside the positioning frame 2, so that the stability of the device in the positioning of the frames of mobile phones with different sizes is ensured, the resetting assembly comprises a telescopic rod 9 and a spring 10, the telescopic rod 9 is sleeved outside the spring 10, the supporting force for resetting is provided, the telescopic rod 9 is fixedly connected between the limiting plates 7 at both ends of the spring 10, so that the limiting plate 7 can quickly return to the initial position when resetting;
[0034] Specifically, when the positioning frame 2 needs to be adjusted, the length and width of the positioning frame 2 can be flexibly adjusted by horizontally or vertically pulling out or retracting the connecting column 4. The connecting column 4 is smoothly slid inside the positioning frame 2 through the sliding block 6, and is accurately positioned by embedding the tooth block 8 arranged inside the sliding block 6 between the tooth block 5, so that the stability of the adjustment is ensured. The tooth block 8 is also limited in sliding inside the sliding block 6 through the limiting plate 7, so as to avoid displacement error, and through the tension support provided by the spring 10, the tooth block 8 is embedded in the tooth block 5 more stably, so as to avoid misplacement, thereby realizing the effect that the positioning frame 2 adapts to the frames of mobile phones with different sizes.
[0035] Referring to Figure 3 and Figure 4The fixing assembly includes a fastening bolt 18, one end of which is rotatably connected to a tapered column 19. By rotating the fastening bolt 18, the tapered column 19 can be inserted into the slider 12, thereby firmly fixing the slider 12 and its internal components in the desired position. The outer wall of the fastening bolt 18 is threaded into the inside of the slider 12 to ensure its stability during adjustment. A connecting plate 20 is slidably connected inside the slider 12, and an anti-slip strip 21 is fixedly connected to one side of the connecting plate 20. The anti-slip strip 21 provides effective friction to prevent the slider 12 from slipping accidentally during adjustment and ensures accurate positioning. The connecting rod assembly includes a connecting rod 13, one end of which is rotatably connected to the top of the slider 12, providing stable support for the slider 12. The other end of the connecting rod 13 is rotatably connected to a pressure rod 14, which is adjusted through the connecting rod 13 to ensure flexible adjustment of the device during operation. A connecting rod 15 is rotatably connected to the top of the slider 12.

The adapter components include a limiting wheel 17 and an L-shaped support rod 16. The limiting wheel 17 can rotate flexibly at both ends of the L-shaped support rod 16, providing a smooth limiting function. The L-shaped support rod 16 is rotatably connected to one end of the second connecting rod 15. Through the connection with the second connecting rod 15, the L-shaped support rod 16 can precisely control the position of the limiting wheel 17, so that the outer wall of the limiting wheel 17 fits against the outer wall of the positioning frame 2, thereby achieving a stable fixing effect. The outer wall of the tapered column 19 fits against the other side of the connecting plate 20, providing effective support force and making the fixing more stable. The second slider 12 is slidably connected inside the adjustment groove 11, ensuring the smoothness and accuracy of the adjustment. The outer wall of the limiting wheel 17 fits against the outer wall of the positioning frame 2, further ensuring the stability of the positioning frame 2. The bottom of the L-shaped support rod 16 fits against the outer wall of the positioning frame 2, increasing the support effect of the overall structure.
[0036] Specifically, when it is necessary to fix the positioning frame 2, firstly, adjust the position of the slider 2 12 so that it slides to a suitable position within the adjustment groove 11. Then, rotate the fastening bolt 18 to allow the conical column 19 to gradually extend into the interior of the slider 2 12. The inclined surface of the outer wall of the conical column 19 pushes the connecting plate 20 out of the outer side of the slider 2 12, so that the connecting plate 20 is firmly attached to the inner wall of the adjustment groove 11 through the anti-slip strip 21, thereby securing it firmly. Next, press down the pressure rod 14. Through the connection points of the connecting rod 1 13 and the connecting rod 2 15, a stable quadrilateral structure is formed. The pressure rod 14, with the connecting rod 1 13 as the fulcrum, drives the connecting rod 2 15 to rotate and press down around the connection point of the slider 2 12. This pushes the limiting wheel 17 to tightly contact the positioning frame 2 through the L-shaped support rod 16, achieving precise fixation of the positioning frame 2. Finally, the pressure rod 14 and the connecting rod 2 15 remain in a horizontal state, ensuring that the entire locking process is stable and reliable, thus achieving a convenient and effective fixation of the positioning frame 2.
[0037] Working principle: when using the auxiliary positioning device of the mobile phone frame welding, first need to adjust the positioning frame 2, only need to pull out or shrink the connecting column two 4 in horizontal or vertical direction to adjust the length and width size of the positioning frame 2, the connecting column two 4 slides in the positioning frame 2 through the slider one 6, is positioned through the tooth block two 8 in the slider one 6 embedded between the tooth block one 5, the tooth block two 8 is limited in the slider one 6 through the limiting plate 7, and is supported through the tension of the spring 10, so that the tooth block two 8 is not easy to dislocation when embedded between the tooth block one 5, reaches the effect of adapting to different size mobile phone frame, when need to fix the positioning frame 2, adjust the position of the slider two 12 in the adjusting groove 11, then rotate the fastening bolt 18 to drive the tapered column 19 to extend into the slider two 12, and the connecting plate 20 is extended out of the slider two 12 through the inclined surface of the outer wall of the tapered column 19, so that the connecting plate 20 is locked by sticking to the adjusting groove 11 through the antiskid strip 21, then press down the pressure rod 14 to form a quadrilateral structure through the connecting rod one 13 and the connecting rod two 15 one end, then the pressure rod 14 drives the connecting rod two 15 to rotate down with the connecting point of the slider two 12 as the fulcrum, and then drives the limiting wheel 17 to contact the positioning frame 2 through the L-shaped support rod 16, and then fixes the positioning frame 2, the pressure rod 14 and the connecting rod two 15 form horizontal state to keep locking, reaches the effect of fixing the positioning frame 2 conveniently.
[0038] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be contained in the protection scope of the utility model.
