For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0019] like Figures 1 to 3 As shown, the present invention proposes a clamping device for mobile phones, comprising: a first clamping block 1 and a second clamping block 2, wherein the first clamping block 1 and the second clamping block 2 are configured in an "L" shape. A rubber pad 14 is fixedly provided on one side of the second clamping block 2 to prevent scratching of the bottom of the mobile phone after clamping. The opposite ends of the first clamping block 1 and the second clamping block 2 are movably connected to each other to ensure stable movement of the first clamping block 1 and the second clamping block 2. A first spring 3 is provided at the connection point of the first clamping block 1 and the second clamping block 2. One end of the first spring 3 is fixedly connected to the first clamping block 1, and the other end of the first spring 3 is fixedly connected to the second clamping block 2 to ensure that there is a restoring elastic force between the first clamping block 1 and the second clamping block 2, thereby stably clamping the mobile phone.

[0020] Furthermore, a hinge seat 4 is fixed to the bottom surface of the first clamping block 1 by bolts. A hinge frame 5 is hinged to one end of the hinge seat 4 to facilitate adjustment of the angle after the mobile phone is clamped. A hand-tightening bolt 6 is threaded onto the hinge frame 5 to facilitate connection and fixation of the clamp to other equipment.

[0021] like Figure 1 , Figure 4 and Figure 5As shown, a limiting component 7 for fixing the mobile phone is provided on one side of the first clamping block 1 and the second clamping block 2. The limiting component 7 includes a fixing plate 701 fixedly disposed on one side of the first clamping block 1. The fixing plate 701 has an installation groove 702 for easy installation of other components. A gear 703 is rotatably disposed inside the installation groove 702. One end of the gear 703 passes through the fixing plate 701 and extends to be connected to a threaded rod 704, so as to drive the threaded rod 704 to move simultaneously. A rack 705 is movably sleeved inside the installation groove 702. One end of the rack 705 is fixedly connected to the second clamping block 2, so as to drive the rack 705 to move simultaneously through the second clamping block 2. The rack 705 is meshed with the gear 703, so as to drive the gear 703 to rotate simultaneously during the movement of the second clamping block 2.

[0022] Secondly, a set of guide rods 706 are movably connected through the fixed plate 701, enabling the guide rods 706 to move stably horizontally. One end of the guide rod 706 is fixedly connected to a limit block 707, which can limit the guide rod 706. The other end of the guide rod 706 is fixedly connected to a limit pressure plate 708, so that the guide rod 706 drives the limit pressure plate 708 to limit the mobile phone and prevent it from moving back and forth. A fixed sleeve plate 709 is fixedly sleeved between the guide rods 706, and a set of support plates 71 is fixedly installed on one side of the fixed sleeve plate 709. 0, and the support plates 710 are symmetrically arranged. Threaded sleeve plates 711 are slidably arranged between the support plates 710. Slide grooves 15 are respectively opened on the opposite surfaces of the support plates 710. A slider is slidably arranged inside the slide grooves 15. The slider is fixedly connected to the threaded sleeve plate 711 and can stably guide the threaded sleeve plate 711 to move. A second spring 712 is fixedly arranged on one side of the threaded sleeve plate 711. One end of the second spring 712 is fixedly connected to the fixed sleeve plate 709 and can push the threaded sleeve plate 711 to press against one end of the threaded rod 704.

[0023] Furthermore, the outer wall of the guide rod 706 is fitted with a third spring 713. One end of the third spring 713 is fixedly connected to the fixing plate 701, and the other end of the third spring 713 is fixedly connected to the fixing sleeve plate 709. This can provide a pushing force to the limiting pressure plate 708, thereby providing a stable limiting force to the rear of the mobile phone and making it easy to pick up and put down.

[0024] like Figure 2 and Figure 3As shown, a guide groove 8 is provided at one end of the first clamping block 1 and the second clamping block 2 respectively. A connecting clamping block 9 is movably sleeved inside the guide groove 8. The connecting clamping block 9 is designed with a "U" shaped structure, which fits the side of the mobile phone better and makes the clamping more stable. A through groove 10 is provided on one side of the first clamping block 1 and the second clamping block 2 respectively. An elastic limiting plate 11 is fixedly installed inside the through groove 10. A convex cap 12 is fixedly installed on one side of the elastic limiting plate 11. A slot 13 is provided on one side of the connecting clamping block 9, which can limit the position of the connecting clamping block 9 and facilitate the adjustment of the height of the connecting clamping block 9, making the clamping of the mobile phone more stable.

[0025] In this embodiment, firstly, firmly grasp the second clamping block 2 and slowly pull it horizontally away from the first clamping block 1. During the pulling process, the first spring 3 connecting the first clamping block 1 and the second clamping block 2 will be gradually stretched due to the pulling force applied by the second clamping block 2. Place the mobile phone between the first clamping block 1 and the second clamping block 2, and then release the second clamping block 2 that has been pulled. At this time, the first spring 3 will quickly take effect, using its own elastic potential energy to drive the second clamping block 2 to return to its original position and move towards the first clamping block 1 until the mobile phone is firmly clamped.

[0026] When the socket clamp 9 is needed, pull the socket clamp 9 along the trajectory of the guide groove 8 to make it move smoothly within the groove. During the movement, carefully observe the position of the socket clamp 9. When it moves to a suitable position that fits the size of the phone, the elastic limiting plate 11 in the through groove 10 on one side of the first clamp 1 and the second clamp 2 will deform due to its own elasticity and smoothly engage with the pre-cut slot 13 on one side of the socket clamp 9, thus achieving a firm fixation of the socket clamp 9. If you want to adjust the height of the socket clamp 9 later, simply pull the protruding cap 12 on the elastic limiting plate 11. The elastic limiting plate 11 will move accordingly, causing the socket clamp 9 to disengage from the slot 13, and then the height can be readjusted and fixed again. It is worth noting that the socket clamp 9 has a "U" shaped structure. This special shape can better fit the edge of the phone and greatly enhance the clamping effect on the phone. During the repositioning process of the second clamping block 2 towards the first clamping block 1, the rack 705 in the limiting assembly 7 is driven accordingly. After the rack 705 begins to move, the gear 703 meshing with it is driven to rotate. Since the gear 703 is fixedly connected to the threaded rod 704, the rotation of the gear 703 is transmitted to the threaded rod 704, causing it to rotate as well. The threaded rod 704 and the threaded sleeve 711 are threadedly connected, so as the threaded rod 704 rotates, the threaded sleeve 711 moves along the axis of the threaded rod 704. During the movement, the threaded sleeve 711 applies a pushing force to the fixed sleeve 709 through the second spring 712 on one side, pushing the fixed sleeve 709 to move. The fixed sleeve 709 is connected to the guide rod 706, thus driving the limiting pressure plate 708 at one end of the guide rod 706 to move towards the rear of the mobile phone clamped between the first clamping block 1 and the second clamping block 2. When the limiting pressure plate 708 moves to the appropriate position, the third spring 713 sleeved on the outer wall of the guide rod 706 will play a role, continuously providing pressure to the limiting pressure plate 708, thereby providing a stable thrust to the rear of the mobile phone, effectively preventing the mobile phone from shaking during the clamping process, and ensuring that the mobile phone is firmly fixed on the clamping device.

[0027] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
