[0025] like Figure 3 As shown, two hanging ears 14 are fixedly installed on the outer surface of the movable plate 9, and a screw rod 15 is movably installed inside the hanging ears 14. The two ends of the screw rod 15 are rotatably connected to the surface of the first main body 7 and the top of the inner wall of the movable groove 8 respectively. The screw rod 15 is externally connected to a power source, and the screw rod 15 drives the movable plate 9 on the hanging ears 14 to move along the axial direction of the screw rod 15, so that the camera 5 can quickly leave the device.

[0026] like Figure 4 As shown, the sealing device 6 includes a second body 16, a rotating groove 17 is opened inside the second body 16, an insert plate 18 is fixedly installed on the end surface of the rotating groove 17 away from the first body 7, and a driving internal gear 9 is rotatably installed on the inner wall of the rotating groove 17. The driving internal gear 19 is connected to an external power source, and the driving internal gear 19 realizes the opening and closing of the sealing device 6 by forward and reverse rotation.
