[0018] When the present invention is in use, inside the stabilizing component, when the device is being equipped, after the telescopic rod is fixed in position, the spring plate is fixed on the surface, and the spring plate will contact the inner wall of the shell. When the device is in use, the equipment is fixed by the elastic force of the contact, and the equipment is buffered at the same time. At the same time, if the spring plate is subjected to extrusion force, the two spring plates will first squeeze the arc plate. When the arc plate is subjected to extrusion force, it will drive the fixed spring to generate elastic force, and through the reaction force of the fixed spring, the device is better buffered. At the same time, the telescopic rod is connected to perform telescopic action, driving the pressure plates at both ends to slide along the surface of the pressure plate slide groove. When the pressure plate is running, it will drive the inner arc clamping plate in the distance adjusting component to run.

[0019] When the present invention is in use, the motor in the distance adjusting component is started to drive the two-way threaded rotating rod to operate. When the two-way threaded rotating rod operates, it will drive the output tooth plate to rotate, and at the same time, through the surface thread connection, drive the two external threaded sleeves on the surface to operate close to each other. At the same time, when the external threaded sleeve operates, it will drive the pulley wheel to slide along the inner wall of the pulley groove. When the pulley wheel operates, it will drive the connecting shaft to operate, and the connecting shaft close to one end of the front plate will drive the front camera to operate, and the connecting shaft close to one end of the rear plate will drive the rear camera to operate. The required distance adjustment is performed by the front camera and the rear camera approaching each other. At the same time, when the front camera and the rear camera are operating, the inner arc card plate on the surface will be driven to operate, and the inner arc card plate will drive the slider to slide along the surface of the slider groove. When the slider is operating, it will drive the slider connecting plate to operate. When the slider connecting plate is operating, it cooperates with the pressure plate in the stabilizing component to operate, so that the front camera and the rear camera in the device can be more synchronized during operation, avoiding damage caused by excessive or too light.

[0020] When the present invention is in use, in the auxiliary component, when the output tooth plate is started, it will drive the transmission gear to run, and when the transmission gear runs, it will drive the inner groove shaft to run, and the inner groove shaft will drive the two sleeve rotating rods to run along the inner wall of the inner groove shaft, and at the same time, the sleeve rotating rod will slide along the surface of the fixed rod. When the sleeve rotating rod runs to a certain position, it will squeeze the extrusion box. After the extrusion box is squeezed, it will buffer the two fixed rods to prevent the front camera and the rear camera from being damaged due to excessive contact when they are too close. At the same time, when the extrusion box is squeezed, it will expand the blow box. When the blow box expands, it will buffer the pressure plates that are close to each other, thereby performing a further protective effect. At the same time, when the two pulleys approach each other to a certain position, they will contact and expand with the surface of the spring pressure plate, and the spring pressure plate will generate elastic force on the buffer spring, and finally protect the pulleys approaching each other through the reaction force of the buffer spring. At the same time, when the front eye camera and the rear eye camera are close to each other, they will drive the front eye slide and the rear eye slide to slide along the inner wall of the bottom groove plate and approach each other, and finally contact and expand with the bottom groove spring plate. The bottom groove spring plate uses the force of the spring plate on the surface to better protect the surface of the other end of the front eye camera and the rear eye camera during operation, and assists in protecting the operation of the front eye camera and the rear eye camera, so as to better adjust the distance of the device.

When the arc plate 23 is subjected to an extrusion force, it will drive the fixed spring 24 to generate an elastic force. Through the reaction force of the fixed spring 24, the device is better buffered. At the same time, the telescopic rod 30 is connected to perform an extension and retraction action, driving the pressure plates 29 at both ends to slide along the surface of the pressure plate slide groove 28. When the pressure plate 29 is running, it will drive the inner arc clamping plate 52 in the distance adjusting component 2 to run. At this time, in the distance adjustment component 2, the motor 4 is started, driving the bidirectional threaded rotating rod 41 to operate. When the bidirectional threaded rotating rod 41 operates, it will drive the output tooth plate 42 to rotate, and at the same time, through the surface thread connection, drive the two external threaded sleeves 43 on the surface to operate close to each other. At the same time, when the external threaded sleeve 43 operates, it will drive the pulley 44 to slide along the inner wall of the pulley groove 48. When the pulley 44 operates, it will drive the connecting shaft 45 to operate. The connecting shaft 45 near one end of the front plate 10 will drive the front camera 6 to operate, and the connecting shaft 45 near one end of the rear plate 11 will drive the rear camera 7 to operate. The required distance adjustment is performed by moving the front camera 6 and the rear camera 7 closer to each other. At the same time, when the front camera 6 and the rear camera 7 are in operation, the inner arc card plate 52 on the surface will be driven to operate, and the inner arc card plate 52 will drive the slider 50 to slide along the surface of the slider groove 49. When the slider 50 is in operation, it will drive the slider connecting plate 51 to operate. When the slider connecting plate 51 is in operation, it will cooperate with the pressure plate 29 in the stabilizing component 1 to operate, so that the front camera 6 and the rear camera 7 in the device can be more synchronized during operation to avoid damage caused by excessive or too light.At this time, in the auxiliary component 3, when the output tooth plate 42 is started, it will drive the transmission gear 61 to run. When the transmission gear 61 runs, it will drive the inner groove shaft 62 to run. The inner groove shaft 62 will drive the two sleeve rotating rods 63 to run along the inner wall of the inner groove shaft 62. At the same time, the sleeve rotating rod 63 will slide along the surface of the fixed rod 64. When the sleeve rotating rod 63 runs to a certain position, it will squeeze the extrusion box 65. After the extrusion box 65 is squeezed, it will buffer the two fixed rods 64 to prevent the front eye camera 6 and the rear eye camera 7 from being damaged due to excessive contact when they are too close. At the same time, when the extrusion box 65 is squeezed, it will expand the blow box 67. When the blow box 67 expands, it will buffer the pressure plates 29 that are close to each other, providing further protection. At the same time, when the two pulley wheels 44 approach each other to a certain position, they will contact and expand with the surface of the spring pressure plate 69, and the spring pressure plate 69 will generate an elastic force on the buffer spring 70, and the reaction force of the buffer spring 70 will eventually protect the pulley wheels 44 approaching each other. At the same time, when the front eye camera 6 and the rear eye camera 7 approach each other, they will drive the front eye slide 73 and the rear eye slide 74 to slide along the inner wall of the bottom groove plate 71 and approach each other, and finally contact and expand with the bottom groove spring plate 72. The bottom groove spring plate 72 uses the force of the spring plate on the surface to better protect the surface of the other end of the front eye camera 6 and the rear eye camera 7 during operation, and assist in protecting the operation of the front eye camera 6 and the rear eye camera 7, so as to better adjust the distance of the device.
