[0026] Specifically, pull the clamping block 11 on one side. At this time, the movement of the clamping block 11 will drive the rotation of the gear 9, and the meshing connection between the rack 10 and the gear 9 on the other side of the clamping block 11 will also move outward. As the gear 9 rotates, the coil spring 8 rolls up to accumulate elastic potential energy, and the mobile phone is placed between the two clamping blocks 11. Release the pulled clamping block 11. Under the action of the elastic potential energy of the coil spring 8, the clamping blocks 11 on both sides will move to the opposite side. When the clamping blocks 11 contact both sides of the mobile phone, the mobile phone will be clamped under the action of the remaining elastic potential energy of the coil spring 8.

When the second cylinder 203 slides to the bottom of the slide groove 204 of the first cylinder 202, the second cylinder 203 is continued to be rotated clockwise, so that the limiting block 205 above it drives the first cylinder 202 to rotate, so that the limiting block 205 above the first cylinder 202 is disengaged from the slot 206 above the fixed column 201, and slides into the fixed column 201. The slide groove 204 above the column 201, and then continue to pull the second cylinder 202 to make it continue to extend. When the required length is reached, the second cylinder 203 is rotated counterclockwise to make the limiting block 205 above the second cylinder 203 engage with the slot 206 in the first cylinder 202. Continuing to rotate the second cylinder 203 can drive the first cylinder 202 to rotate, so that the limiting block 205 above it engages with the slot 206 above the fixed column, thereby completing the extension and fixation.

[0029] Reference Figure 1 、 Figure 2 and Figure 3 , the bottom of the inner wall of the fixed block 1 is fixedly connected to the battery box 12, and the rear side of the inner wall of the fixed block 1 is rotatably connected to the rotating plate 13; the bottom of the front end of the hollow block 7 is fixedly connected to a U-shaped buffer pad 14, and the front end of the clamping block 11 is provided with an arc groove 15; the middle part of the front end of the hollow block 7 is fixedly connected to a groove block 16, and a clamping block 17 is provided on the front side of the groove block 16, and the clamping block 17 is engaged with the groove block 16, and the front side of the clamping block 17 is fixedly connected to a threaded column 18; the front end of the fixed block 1 is fixedly connected to a controller 21, and the controller 21 is electrically connected to the DC motor 4 and the servo motor 6 respectively; the outer side of the controller 21 is fixedly connected to the outer side of the shell 22, and the outer side of the shell 22 is rotatably connected to the protective cover 23;

[0031] Working principle: Before using the device, first, when pulling the clamping block 11 on either side, the movement of the clamping block 11 will trigger the rotation of the gear 9. At the same time, due to the meshing connection between the rack 10 and the gear 9, the clamping block 11 on the other side will also move outward. During the rotation of the gear 9, the coil spring 8 begins to wind and accumulate elastic potential energy. At this time, the mobile phone can be safely placed between the two clamping blocks 11. Once the clamping block 11 is released, the elastic potential energy accumulated by the coil spring 8 will be released, prompting the clamping blocks 11 on both sides to move toward each other. When the clamping blocks 11 are in close contact with both sides of the mobile phone, the coil spring 8 will start to wind and accumulate elastic potential energy. The remaining elastic potential energy of the spring 8 will ensure that the mobile phone is firmly clamped. By starting the DC motor 4, the rotating block 5 and the mobile phone clamped thereon can be driven to rotate in the vertical direction. In addition, starting the servo motor 6 can drive the hollow block 7 and the mobile phone clamped thereon to rotate in the horizontal direction. This design allows the camera to always maintain a horizontal and stable posture when holding the device, thereby effectively reducing the blurring of the captured image caused by shaking during holding. In addition, through the telescopic mechanism 2, when the camera needs to be extended when shooting, the second cylinder 203 should be rotated first to make the second cylinder 203 located thereon rotate. The upper limiting block 205 is unlocked and separated from the card slot 206 at the top of the first cylinder 202, and slides smoothly along the slide slot 204 above the first cylinder 202. Then, the second cylinder 203 is pulled toward the bottom of the first cylinder 202 along the slide slot 204 to achieve its extension operation. When the second cylinder 203 slides to the bottom limit position of the slide slot 204 of the first cylinder 202, it is necessary to continue to rotate the second cylinder 203 in the clockwise direction. At this time, the limiting block 205 above it will drive the first cylinder 202 to rotate synchronously, so that the limiting block 205 at the top of the first cylinder 202 is released from the fixed column 2 01 is unlocked and separated, and slides into the sliding groove 204 above the fixed column 201. Then, continue to pull the second cylinder 202 to make it continue to extend until it reaches the length required for shooting. After the extension is completed, the second cylinder 203 is rotated counterclockwise to re-engage the limiting block 205 above the second cylinder 203 with the slot 206 in the first cylinder 202. Continuing to rotate the second cylinder 203 can drive the first cylinder 202 to rotate until the limiting block 205 above it engages with the slot 206 above the fixed column, thereby completing the fixing operation after extension.
