Description

Technical Field

[0001] This utility model relates to the field of mobile phones, specifically a mobile phone extension rod. Background Technology

[0002] With the widespread use of smartphones and the improvement of their photography functions, more and more people are using their phones to take pictures. However, when taking selfies or shooting distant scenes, the fixed angle of the phone camera often makes it difficult to achieve satisfactory results. Therefore, various phone extension rods have emerged on the market. The extension rod body allows for adjustment of the rod's pivot position to change the shooting angle, meeting different shooting needs and enabling users to obtain a wider field of view. For example, when shooting landscapes, architecture, and other large scenes, the phone can be extended further to include more elements in the frame. It can also help users easily achieve special perspectives such as low-angle and high-angle shooting, such as simulating a drone's perspective for overhead shooting, or shooting close to the ground to obtain unique low-angle effects, adding creativity to the shooting.

[0003] However, some products suffer from poor stability and inconvenient operation. Existing extension rods typically only clamp the phone from both sides. During shooting, especially when shooting dynamic scenes or in unstable environments, the phone is prone to loosening and slipping, which cannot guarantee the stability and safety of the shooting. Therefore, we have proposed a phone extension rod. Utility Model Content

[0023] Furthermore, the clamping structure includes a clamping sleeve 3, a clamping plate 4, a spring 16, and guide rods 15. One side of the clamping sleeve 3 is fixedly connected to one end of the rotating rod of the rotating frame 2. The open side of the clamping sleeve 3 is perpendicular to one end of the plane of the rotating frame 2. The side of the clamping sleeve 3 facing away from the open side is fixedly connected to the clamping plate 4, which faces away from the rotating frame 2. Multiple evenly distributed guide rods 15 are fixedly connected to the opposite side of the inner opening of the clamping sleeve 3. Each guide rod 15 on the opposite side of the inner opening of the clamping sleeve 3 is fixedly connected to one end of the spring 16, and the guide rod 15 is inside the spring 16. The clamping sleeve 3 is the main support tube for clamping the mobile phone. The clamping plate 4 is used to clamp the two sides of the mobile phone, and the spring 16 is used to provide the force for clamping the mobile phone.

[0024] Furthermore, the clamping structure also includes a telescopic rod 10, a guide hole 11, and a clamping plate 4. The telescopic rod 10 has multiple equidistantly distributed guide holes 11 through one side. The telescopic rod 10 is inserted and connected between the clamping sleeves 3, and the guide holes 11 are inserted and connected to the guide rod 15. The end of the spring 16 away from the clamping sleeve 3 is fixedly connected to the end of the telescopic rod 10 inside the clamping sleeve 3. The end of the telescopic rod 10 outside the clamping sleeve 3 is fixedly connected to the clamping plate 4. The clamping plate 4 of the telescopic rod 10 corresponds to the clamping plate 4 of the clamping sleeve 3. The guide rod 15 and the guide hole 11 slide relative to each other to make the telescopic rod 10 slide stably when it extends and retracts. The telescopic rod 10 extends and retracts between the clamping sleeves 3, and the spacing is adjusted according to the actual length of the mobile phone.

[0025] Furthermore, the auxiliary clamping structure includes a trapezoidal slider 9, a clamping sleeve 2 5, a telescopic rod 2 6, a guide rod 2 12, a trapezoidal groove 19, a guide hole 2 17, and a spring 20. The clamping sleeve 2 3, without openings and not connected to the rotating frame 2, has its symmetrical sides fixedly connected to the short side of the trapezoidal slider 9. The clamping sleeve 2 5 has a trapezoidal groove 19 on its side away from the opening, corresponding to and engaging with the trapezoidal slider 9. Multiple evenly distributed guide rods 2 12 are fixedly connected to the opposite side of the inner opening of the clamping sleeve 2 5. Each guide rod 2 12 on the opposite side of the inner opening of the clamping sleeve 2 5 is fixedly connected to one end of the spring 20, with the guide rod 2 12 inside the spring 20. The telescopic rod 2 6 has multiple equidistant branches extending through one side. The guide hole 17 of the cloth is inserted between the telescopic rod 6 and the clamping sleeve 5, and the guide hole 17 is inserted into the guide rod 12. The end of the spring 20 away from the clamping sleeve 5 is fixedly connected to the end of the telescopic rod 6 inside the clamping sleeve 5. The trapezoidal slider 9 and the trapezoidal groove 19 are used to slide the clamping sleeve 3 and the clamping sleeve 5. The clamping sleeve 5 and the telescopic rod 6 are used to clamp the mobile phone in the width direction. The guide rod 12 and the guide hole 17 slide relative to each other to make the telescopic rod 6 slide stably when it extends and retracts. The spring 20 is used to provide the force to clamp the mobile phone. The sliding of the trapezoidal slider 9 and the trapezoidal groove 19 is used to adjust the position of the clamping sleeve 5 and the telescopic rod 6 relative to the mobile phone, avoiding the button position of the mobile phone, and clamping stably from four directions.

[0026] Furthermore, the auxiliary clamping structure also includes a clamping groove 21, a second clamping plate 7, a hinge rod 13, and a hinge hole 14. The second telescopic rod 6 has a clamping groove 21 on the side of the first clamping plate 4 away from the second clamping sleeve 5. The inner wall of the clamping groove 21 is fixedly connected to one end of the hinge rod 13 on both sides symmetrically away from the second clamping sleeve 5. The second clamping plate 7 has a hinge hole 14 through one side. The hinge hole 14 and the hinge rod 13 are hingedly connected between the second clamping plate 7 and the clamping groove 21. The clamping groove 21 is used to install the second clamping plate 7. The hinge rod 13 and the hinge hole 14 are used to hinge the telescopic rod 6 and the second clamping plate 7. When clamping in the width direction is required, the second clamping plate 7 and the clamping groove 21 are separated to clamp the mobile phone.

[0027] Furthermore, the clamping sleeve 2 5 is fixedly connected to the metal block 18 on the side corresponding to the rotating frame 2, and the clamping sleeve 1 3 is fixedly connected to multiple magnetic blocks 8 on the side opposite to the rotating frame 2. The magnetic blocks 8 correspond to the metal block 18. When the bracket is not used, in order to save carrying space, when the trapezoidal slide groove 19 of the clamping sleeve 2 5 slides to one side on the trapezoidal slider 9, the clamping sleeve 2 5 and the clamping sleeve 1 3 separate, and the metal block 18 of the clamping sleeve 2 5 is magnetically connected to the magnetic blocks 8 of the clamping sleeve 1 3. In addition, when clamping the mobile phone, the magnetic blocks 8 have a slight magnetic attraction to the mobile phone to stabilize the clamping of the mobile phone.

[0028] Working principle: One end of the extension rod 1 is hinged to the rotating frame 2, allowing for rotation at a certain angle to facilitate adjustment of the shooting angle. The rotating rod connected to the rotating frame 2 drives the clamping structure at the end to rotate flexibly, meeting the needs of different shooting angles. The clamping plate 4 is fixed on the side of the clamping sleeve 3 away from the opening, used to clamp the phone from one side. Inside the clamping sleeve 3, multiple guide rods 15 are evenly distributed on the two opposite sides of the opening. The springs 16 connected to the guide rods 15 provide clamping force to the clamping plate 4 in the direction of the phone, thereby clamping the phone from one side. The telescopic rod 10 is inserted between the clamping sleeves 3, one of which... Multiple equidistant guide holes 11 are provided on the surface, which are inserted into the guide rod 15. The other end of the spring 16 is connected to one end of the telescopic rod 10 inside the clamping sleeve 3. The end of the telescopic rod 10 outside the clamping sleeve 3 is also fixedly connected to the clamping plate 4. When facing mobile phones of different lengths, the telescopic rod 10 can extend and retract between the clamping sleeves 3. The guide rod 15 slides relative to each other in the guide holes 11 to ensure stable extension and retraction, thereby adjusting the distance between the two clamping plates 4 to adapt to the length of the mobile phone. The clamping sleeve 25 is connected to both sides of the clamping sleeve 3 by trapezoidal sliders 9. The trapezoidal sliders 9 and the trapezoidal grooves on the clamping sleeve 25 are connected to each other. The 19-pin engagement allows for relative sliding between the two components. The guide rod 12 inside the clamping sleeve 2 5 is connected to the spring 20. The telescopic rod 6 is inserted between the clamping sleeves 2 5, with its guide hole 2 17 connecting to the guide rod 12. The spring 20 provides force to the telescopic rod 6 in the direction of the phone, enabling the clamping sleeve 2 5 and the telescopic rod 2 6 to clamp the phone from the width direction. The position of the clamping sleeve 2 5 and the telescopic rod 2 6 relative to the phone can be adjusted by sliding the trapezoidal slider 9 and the trapezoidal groove 19, avoiding the phone's buttons while stably clamping the phone from four directions. The clamping plate 2 7 is connected by the hinge rod 13 and the hinge hole 14. Hinged to the telescopic rod 6, when a more stable clamping of the phone is required in the width direction, the clamping plate 7 can be separated from the clamping plate groove 21 and come into contact with the phone to enhance the clamping effect. When the phone extension rod is not used, to save carrying space, the trapezoidal slide groove 19 of the clamping sleeve 5 can be slid to one side along the trapezoidal slider 9 to separate the clamping sleeve 5 and the clamping sleeve 3. Then, the metal block 18 on the clamping sleeve 5 is magnetically connected to the magnetic block 8 on the clamping sleeve 3 to achieve compact storage. When clamping the phone, a certain magnetic attraction force is generated between the magnetic block 8 and the phone, further enhancing the stability of the phone clamping.
