Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 1 - Figure 5 The present invention provides an embodiment of an automatic locking phone holder, comprising a front shell 1 and a rear shell 2. The front shell 1 and the rear shell 2 are made of engineering plastic, which has a certain strength and toughness, providing a support structure for the entire holder, accommodating internal components such as fixing components and limiting components, while protecting the internal components from external impacts, and providing a bearing surface for the phone. Limiting components are provided at the bottom of the front shell 1 and the rear shell 2, which are used to limit the position of the bottom of the phone. Fixing components are provided inside the front shell 1 and the rear shell 2, which are responsible for fixing the two sides of the phone, adapting to the fixing needs of phones of different sizes.

[0038] The fixing assembly includes symmetrical side panels 13, which are made of a plastic shell and a rubber liner. These panels prevent scratches on the phone's casing and provide sufficient clamping force to secure the phone from both sides. Connecting blocks 8 are fixedly connected to the side walls of each side panel 13, connecting the side panels 13 to other components and allowing movement of the side panels 13. The outer walls of the connecting blocks 8 are slidably connected to the interiors of the front shell 1 and the rear shell 2. Each outer wall of the connecting blocks 8 has a limiting groove 14, formed by machining during manufacturing. This groove 14 engages with the locking plate 7 in the unlocking assembly to lock and unlock the connecting blocks 8. An unlocking assembly is located on the side of the limiting groove 14, controlling the locking and unlocking states of the connecting blocks 8. To facilitate user placement and removal of the phone, fixing blocks 15 are fixedly connected to the other side of the outer wall of connecting block 8 to fix the two ends of the limiting spring 10. Limiting springs 10 are installed between the fixing blocks 15. Their function is to store elastic potential energy when the push plate 9 is pressed, and release the elastic potential energy when the push plate 9 is released, pulling the fixing blocks 15 and side guard plates 13 to reset, thus clamping the phone. The two ends of the limiting spring 10 are fixedly connected to the side walls of the fixing blocks 15. Connecting arms 11 are fixedly connected to the bottom of connecting block 8 to connect the push plate 9 and connecting block 8, transmitting the displacement of the push plate 9 and driving the connecting block 8 to move. The outer walls of the connecting arms 11 are slidably connected to the inside of the front shell 1 and the rear shell 2. The side walls of the connecting arms 11 are fixedly connected to the push plate 9, providing the user with operating... The side guard plate 13 is positioned as a pressure point, allowing users to control its opening and closing by pressing the pusher plate 9. The pusher plate 9 is located on the left and right sides of the outer walls of the front shell 1 and the rear shell 2. An indicator arrow 12 is provided on the side wall of the connecting arm 11 to indicate the direction of movement of the connecting arm 11 and the side guard plate 13. Multiple screw holes 3 are provided inside both the front shell 1 and the rear shell 2. These screw holes 3 are formed during mold manufacturing or machining and are used to connect the front shell 1 and the rear shell 2 with screws. A mounting base 4 is fixedly connected to the side wall of the rear shell 2. The mounting base 4 is used to connect the bracket to the connection point, ensuring the overall stability of the bracket. Multiple anti-slip grooves 22 are provided on the side wall of the front shell 1. These anti-slip grooves 22 are grooves formed during the manufacturing process of the front shell 1 and are distributed in an array. The anti-slip groove 22 is used to increase the friction between the front shell 1 and the mobile phone. The limiting component includes a support plate 19, which supports the bottom of the mobile phone. A corrugated plate 20 is fixedly connected to the top of the support plate 19. Its sidewalls are corrugated. This special shape can increase the contact area with the limiting post 18 and improve the limiting effect. The corrugated plate 20 is slidably connected inside the front shell 1 and the rear shell 2. The sidewalls of the corrugated plate 20 are corrugated. Positioning posts 21 are provided on the left and right sides of the corrugated plate 20 to limit the lateral movement of the corrugated plate 20. When the mobile phone is placed in place, the corrugated plate 20 is locked to prevent it from moving downwards and to ensure that the corrugated plate 20 moves stably in the vertical direction. One end of the positioning post 21 is fixedly connected to the inner wall of the front shell 1, and the other end of the positioning post 21 is slidably connected to the inside of the rear shell 2.A limiting post 18 is provided on the side of the corrugated plate 20. The side wall of the limiting post 18 is fixedly connected to the inside of the rear shell 2. The limiting post 18 is used to limit the movement range of the corrugated plate 20. The unlocking assembly includes an unlocking plate 5, which provides an operating part for the user. By pressing the unlocking plate 5, the movement of the locking plate 7 is controlled, thereby unlocking the connecting block 8. The bottom of the unlocking plate 5 is fixedly connected to the locking plate 7, which is located on the side of the limiting groove 14. A spring hole 16 is fixedly connected to the top of the inner wall of the rear shell 2. A return spring 6 is provided inside the spring hole 16. Its function is to store elastic potential energy when the unlocking plate 5 is pressed, and to release the elastic potential energy when the unlocking plate 5 is released, pushing the unlocking plate 5 and the locking plate 7 back to their initial positions. One end of the return spring 6 is fixedly connected to the side wall of the return spring 6, and the other end is fixedly connected to the inside of the spring hole 16. Connecting seats 17 are provided on the left and right sides below the spring hole 16. The side walls of the connecting seats 17 are fixedly connected to the inner wall of the rear shell 2. The left and right sides of the locking plate 7 are rotatably connected to the inside of the connecting seats 17.

[0039] Specifically, when using this automatic lock phone holder, the user first places their fingers on the left and right push-button plates 9 respectively, and presses the push-button plates 9 towards the center of the holder. The displacement of the push-button plates 9 causes the connecting blocks 8 to move outwards to both sides via the connecting arms 11. The connecting arms 11 are fixedly connected to both the push-button plates 9 and the connecting blocks 8. When the push-button plates 9 move, the connecting arms 11 move synchronously, thereby causing the connecting blocks 8 to move. The displacement of the connecting blocks 8 then causes the side guard plates 13 to move synchronously. The side guard plates 13 are fixedly connected to the connecting blocks 8. When the connecting blocks 8 move, the side guard plates 13 move synchronously, moving from near the center of the holder. The position shifts linearly to both sides of the bracket, increasing the distance between the side guards 13. At the same time, the limiting groove 14 at the front of the connecting block 8 also shifts. The limiting groove 14 and the connecting block 8 are an integral structure. When the connecting block 8 shifts, the limiting groove 14 shifts synchronously. The limiting spring 10 at the rear of the connecting block 8 is also stretched. The two ends of the limiting spring 10 are fixed to the fixing blocks 15 of the connecting blocks 8 on both sides. When the connecting block 8 shifts to both sides, the limiting spring 10 is gradually stretched, and the elastic potential energy increases continuously. At this time, the user inserts the mobile phone between the side guards 13 from above, ensuring that the mobile phone is in the center position of the side guards 13. Subsequently, the user releases the push plate 9, and under the reset force of the limit spring 10, pulls the fixing blocks 15 on both sides to reset, thereby causing the side guard plate 13 to clamp the sides of the phone. Through the friction between the side guard plate 13 and the phone, the phone is fixed to the bracket. At the same time, the reset spring 6, pushed by the unlocking plate 5, drives the locking plate 7 to rotate from a position away from the limit groove 14 towards the limit groove 14, with its rotational connection point with the connecting seat 17 as the axis, until the locking plate 7 is inserted into the limit groove 14, thereby limiting the position of the connecting blocks 8 on both sides, completing the fixation of the sides of the phone. When the phone is placed downwards, the bottom of the phone will contact the support plate 19, thereby driving the support plate 19 to move. The phone moves downwards, and the support plate 19 moves downwards, causing the corrugated plate 20 to move downwards as well. When the phone stops moving downwards, the limiting post 18 holds the corrugated plate 20 in place, preventing it from moving further downwards. This completes the fixation of the bottom of the phone, achieving the effect of quickly fixing phones of different sizes. When it is necessary to restore the bracket to its original state, the user extends their finger and presses the unlocking plate 5. The displacement of the unlocking plate 5 causes the reset spring 6 to be compressed, which also drives the locking plate 7 to rotate. From the position where it is inserted into the limiting groove 14, it rotates away from the limiting groove 14 and disengages from the limiting groove 14. At this time, under the pull of the limiting spring 10, the connecting blocks 8 on both sides reset, allowing the bracket to return to its initial state.

[0040] Working principle: When using this automatic locking phone holder, the user first manually presses the left and right push plates 9 inward. The displacement of the push plates 9, through the connecting arms 11, causes the connecting blocks 8 to move outward to both sides. The displacement of the connecting blocks 8 then causes the side guard plates 13 to move synchronously. At the same time, the limiting groove 14 at the front of the connecting blocks 8 also moves, and the limiting spring 10 at the rear of the connecting blocks 8 is stretched. At this time, the user inserts the phone between the side guard plates 13 from above. Then, the user releases the push plates 9. Under the reset force of the limiting springs 10, the fixing blocks 15 on both sides are pulled back to their original positions, thereby causing the side guard plates 13 to clamp the sides of the phone. At the same time, the reset spring 6, pushed by the unlocking plate 5, drives the locking plate 7. The phone is secured by inserting into the limiting groove 14, thereby limiting the position of the connecting blocks 8 on both sides. When the phone is placed downwards, the bottom of the phone will contact the support plate 19, which will cause the support plate 19 to move downwards. The movement of the support plate 19 will cause the corrugated plate 20 to move downwards as well. When the phone stops moving downwards, the limiting post 18 will lock the corrugated plate 20, thus securing the bottom of the phone. This achieves the effect of quickly securing phones of different sizes. When it is necessary to restore the bracket to its original state, the user presses the reset spring 6, which compresses the unlocking plate 5 and drives the locking plate 7 to rotate and disengage from the limiting groove 14. At this time, the connecting blocks 8 on both sides will reset under the pull of the limiting spring 10.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
