Pull the rotating arm upward, the limit plate slides downward in the vertical limit groove, the rotating arm moves upward away from the stand, the rectangular block is removed from the rectangular groove, and the camera body can be removed from the stand; S3. Hold the stand and press the rotating pressing block forward. The rotating pressing block drives the moving stand forward, and the moving stand drives the second rack plate to move. The second rack plate meshes with the seventh gear, driving the seventh gear to rotate. The seventh gear drives the threaded rod to rotate, and the threaded rod drives the limit plate to move. The limit plate is pulled out from the fifth gear, releasing the fixing of the rotating arm on the inner side of the stand. S4. Pull the rotating arm forward, the rotating arm will rotate relative to the rectangular block, the second gear will move in a circle relative to the first gear, the second gear will rotate, driving the third gear to rotate, the third gear will drive the fourth gear to rotate, and the rotation of the third gear and the fourth gear will drive the movable block to extend from the bottom end of the rotating arm.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the camera of the present invention can be deflected forward on the rotating arm through the cooperation of the rectangular block and the rectangular groove, so that when the camera body shoots the desktop, the movable block extends backward from the bottom end of the rotating arm, and the rotating arm and the movable block are respectively located on the front and rear sides of the stand, and the device presents a stable "T" shape structure, and the center of gravity of the device is located in the middle, which can improve the installation stability of the device and ensure stable shooting of the device.

[0015] A balancing structure and a limiting structure are provided. When the camera body needs to be removed from the device, first hold the stand and use the thumb to press the disassembly pressing block backwards. The disassembly pressing block drives the moving frame to move backwards on the inner side of the rotating arm, and the moving frame drives the second rack plate to approach the fifth gear and move away from the seventh gear. At this time, the second rack plate is separated from the seventh gear, so the movement of the second rack plate will not drive the seventh gear to rotate. The second rack plate can mesh with the fifth gear when moving, and drive the fifth gear to rotate. The rotation of the fifth gear drives the sixth gear to rotate through the first chain assembly, and the sixth gear and the third gear are connected. The rack plate is meshed, so the rotation of the sixth gear drives the baffle plate to move inside the rectangular groove through the third rack plate, so that the baffle plate moves backward in the rectangular groove, and the baffle plate releases the blockage of the upper end of the rectangular groove, thereby releasing the limit of the rectangular block inside the rectangular groove. Then, the rotating arm is pulled upward with the other hand, and the limit plate slides downward in the vertical limit groove, so that the rotating arm moves upward away from the stand, and drives the rectangular block to be taken out of the rectangular groove, so that the camera body can be removed from the stand, which is convenient for moving the camera body without moving the base and the stand together, thereby reducing the volume and enhancing the practicality of the device. When it is necessary to shoot an object on the desktop, first hold the stand and use the index finger to press the rotating pressing block forward. The rotating pressing block drives the mobile stand to move forward inside the rotating arm, and the mobile stand drives the second rack plate to approach the seventh gear and move away from the fifth gear. At this time, the second rack plate is separated from the fifth gear, so the movement of the second rack plate will not drive the fifth gear to rotate. The second rack plate can mesh with the seventh gear when moving, and drive the seventh gear to rotate. The rotation of the seventh gear drives the threaded rod to rotate through the second chain assembly. The threaded rod is threadedly connected to the limit plate. The rotation of the threaded rod drives the limit plate to move left and right in the stand, so that the end of the limit plate is pulled out of the fifth gear and retracted into the surface of the stand, which can release the fixation of the rotating arm on the inside of the stand. At this time, use the other hand to pull the rotating arm forward so that the rotating arm rotates forward inside the stand. Since the rectangular block is fixed in the rectangular groove, the rotation of the rotating arm cannot drive the rectangular block to rotate, and the rotating arm will rotate relative to the rectangular block, so that the second gear rotatably installed on the inner wall of the rotating arm will rotate relative to the first gear fixed on the rectangular block. The second gear meshes with the first gear, so when the second gear rotates with the rotating arm, it will rotate under the action of the first gear, and the second gear will drive the third gear to rotate, and the third gear will drive the fourth gear meshed with it to rotate. Since the third gear and the fourth gear are both meshed with the first rack plate fixed on the inner wall of the movable block, the rotation of the third gear and the fourth gear will drive the movable block to extend from the bottom end of the rotating arm through the first rack plate. Since the upper end of the rotating arm rotates forward on the stand, the bottom end of the rotating arm is on the stand The frame is rotated upward and backward, so the rotating arm and the movable block are respectively located at the front and rear sides of the upper end of the stand. At this time, the device is in a stable "T" shape, and the center of gravity of the device is located in the middle, which can improve the installation stability of the device and ensure stable shooting of the device. At this time, the limit plate will be aligned with the horizontal limit groove, and the rotating pressing block will be released. The mobile frame will be reset in the stand under the action of the spring, and the limit plate can be extended from the surface of the stand and inserted in the horizontal limit groove, which can fix the angle of the rotating arm on the stand, thereby ensuring the stability of the device and improving the user experience.

[0026] A method for using a detachable camera of a computer: S1. Hold the stand 11 and press the disassembly pressing block 33 backward. The disassembly pressing block 33 drives the movable frame 31 to move backward. The second rack plate 32 is engaged with the fifth gear 36, driving the fifth gear 36 to rotate. The fifth gear 36 drives the sixth gear 38 to rotate. The sixth gear 38 is engaged with the third rack plate 310. The sixth gear 38 drives the baffle 39 to move. The baffle 39 moves backward to release the blockage of the rectangular groove 12, thereby releasing the limit of the rectangular block 21 on the inner side of the rectangular groove 12. S2. Pull the rotating arm 13 upward, the limit plate 314 slides downward in the vertical limit groove 16, the rotating arm 13 moves upward away from the stand 11, the rectangular block 21 is removed from the rectangular groove 12, and the camera body 15 can be removed from the stand 11; S3.

The seventh gear 311 drives the threaded rod 313 to rotate. The threaded rod 313 drives the limit plate 314 to move. The limit plate 314 is pulled out from the fifth gear 36 to release the fixing of the rotating arm 13 on the inner side of the stand 11. S4. Pull the rotating arm 13 forward, the rotating arm 13 will rotate relative to the rectangular block 21, the second gear 23 will move in a circle relative to the first gear 22, the second gear 23 rotates, driving the third gear 24 to rotate, the third gear 24 drives the fourth gear 25 to rotate, the rotation of the third gear 24 and the fourth gear 25 drives the movable block 26 to extend from the bottom end of the rotating arm 13, Working principle: when the camera body 15 needs to be removed from the device, first hold the stand 11 and use the thumb to press the disassembly pressing block 33 backwards. The disassembly pressing block 33 drives the movable frame 31 to move backwards inside the rotating arm 13, and the movable frame 31 drives the second rack plate 32 to approach the fifth gear 36 and move away from the seventh gear 311. At this time, the second rack plate 32 is separated from the seventh gear 311, so the movement of the second rack plate 32 will not drive the seventh gear 311 to rotate. The second rack plate 32 can mesh with the fifth gear 36 when moving, and drive the fifth gear 36 to rotate. The rotation of the fifth gear 36 drives the sixth gear 38 to rotate through the first chain assembly 37. The sixth gear 38 is meshed with the third rack plate 310, so the rotation of the sixth gear 38 is driven by the third rack plate 310. The baffle 39 moves inside the rectangular groove 12, so that the baffle 39 moves backward inside the rectangular groove 12, and the baffle 39 releases the blockage of the upper end of the rectangular groove 12, thereby releasing the limit of the rectangular block 21 inside the rectangular groove 12, and then the rotating arm 13 is pulled upward with the other hand, and the limit plate 314 slides downward in the vertical limit groove 16, so that the rotating arm 13 moves upward away from the stand 11, and drives the rectangular block 21 to be taken out of the rectangular groove 12, so that the camera body 15 can be removed from the stand 11, which is convenient for moving the camera body 15, and the camera body 15 can be placed on a smooth installation surface through the suction cup 28, so that the camera body 15 can be quickly placed at the required position for use, without the need to move the base 1 and the stand 11 together, thereby reducing the volume and enhancing the practicality of the device; When it is necessary to photograph an object on the desktop, first hold the stand 11 and use the index finger to press the rotating pressing block 34 forward. The rotating pressing block 34 drives the movable frame 31 to move forward inside the rotating arm 13. The movable frame 31 drives the second rack plate 32 to approach the seventh gear 311 and move away from the fifth gear 36. At this time, the second rack plate 32 is separated from the fifth gear 36. Therefore, the movement of the second rack plate 32 will not drive the fifth gear 36 to rotate. The second rack plate 32 can mesh with the seventh gear 311 when moving, and drive the seventh gear 311 to rotate. The rotation of the seventh gear 311 drives the threaded rod 313 to rotate through the second chain assembly 312. The threaded rod 313 The threaded rod 313 is threadedly connected to the limit plate 314. The rotation of the threaded rod 313 drives the limit plate 314 to move left and right in the stand 11, so that the end of the limit plate 314 is pulled out from the fifth gear 36 and retracted into the surface of the stand 11, which can release the fixation of the rotating arm 13 on the inner side of the stand 11. At this time, the rotating arm 13 is pulled forward with the other hand to make the rotating arm 13 rotate forward on the inner side of the stand 11. Since the rectangular block 21 is fixed in the rectangular groove 12, the rotation of the rotating arm 13 cannot drive the rectangular block 21 to rotate, and the rotating arm 13 will rotate relative to the rectangular block 21, so that the second gear 23 rotatably mounted on the inner wall of the rotating arm 13 will rotate relative to the rectangular block 21. The first gear 22 on the block 21 moves in a circle, and the second gear 23 meshes with the first gear 22. Therefore, when the second gear 23 rotates with the rotating arm 13, it will rotate under the action of the first gear 22, and the second gear 23 will drive the third gear 24 to rotate, and the third gear 24 will drive the fourth gear 25 meshed with it to rotate. Since the third gear 24 and the fourth gear 25 are both meshed with the first rack plate 27 fixed on the inner wall of the movable block 26, the rotation of the third gear 24 and the fourth gear 25 will drive the movable block 26 to extend from the bottom end of the rotating arm 13 through the first rack plate 27. Since the upper end of the rotating arm 13 rotates forward on the stand 11, the rotating The bottom end of the arm 13 rotates backward on the stand 11, so the rotating arm 13 and the movable block 26 are respectively located at the front and rear sides of the upper end of the stand 11. At this time, the device is in a stable "T" shape, and the center of gravity of the device is located in the middle, which can improve the installation stability of the device and ensure stable shooting of the device. At this time, the limit plate 314 will be aligned with the horizontal limit groove 17, and the rotating pressing block 34 will be released. The movable frame 31 will be reset in the stand 11 under the action of the spring 35, and the limit plate 314 can be extended from the surface of the stand 11 and inserted in the horizontal limit groove 17, which can fix the angle of the rotating arm 13 on the stand 11, thereby ensuring the stability of the device and improving the user experience.
