The outer periphery of the cross bar 71 is fixedly sleeved with an active bevel gear 74 near the middle position. A driven bevel gear 75 is meshed on one side of the active bevel gear 74. A worm 76 is fixedly installed at the center of one side of the driven bevel gear 75. The end of the worm 76 movably passes through one side of the inner cavity of the protective box 1 and is rotatably connected to the other side of the inner cavity of the protective box 1. (Bearings are fixedly installed near the bottom on both sides of the inner cavity of the protective box 1 , and one end of the worm 76 passes through the inner cavity of the adjacent bearing and is inserted into the inner cavity away from the bearing) The front side of the worm 76 is meshed with a worm wheel 77 near both ends, and a threaded tube 78 is penetrated at the top center of the worm wheel 77, and the bottom of the threaded tube 78 is rotatably connected to the bottom of the inner cavity of the protective box 1, and the inner cavity of the threaded tube 78 is threadedly connected with a threaded rod 79, and the top of the threaded rod 79 is fixedly connected to the connecting plate 3. When the two threaded tubes 78 rotate, the threaded rods 79 threaded in the inner cavities of adjacent threaded tubes 78 can jointly move the connecting plate 3 upward to expose it, thereby facilitating the search and rescue work.

[0030] The front and rear ends of the cross bar 71 are rotatably connected to support blocks B711, and one side of the support blocks B711 is fixedly connected to the protection box 1 to facilitate supporting the cross bar 71.

The front end of the movable shaft 821 is rotatably connected to a rectangular block 822, and the bottom of the rectangular block 822 is fixedly connected to the support plate 86. The pawl 82 can be connected by setting the movable shaft 821.

[0039] Specifically, when the search and rescue work is completed, the telescopic rod 85 and the spring 851 can be squeezed by pressing the pressing plate 841 downward, so that the movable plate 84 can be moved downward, and the hinged rod 83 hinged on the movable plate 84 can make the pawl 82 deflect around the movable shaft 821, so that the pawl 82 is separated from the ratchet 81. At this time, the top cover 2 is flipped over, and the bottom of the top cover 2 is fitted with the top of the protective box 1. Then the pressing plate 841 is released, and the pawl 82 is tightly fitted with the ratchet 81 under the elastic force of the spring 851.

The active bevel gear 74 fixedly sleeved on the cross bar 71 can be driven to rotate the driven bevel gear 75 meshing therewith, thereby rotating the worm 76 fixed on the driven bevel gear 75. During the rotation of the worm 76, the two worm wheels 77 meshing therewith can be rotated, thereby rotating the adjacent threaded tube 78. Under the rotation of the threaded tube 78, the threaded rod 79 threadedly connected in the inner cavity of the threaded tube 78 jointly moves the radar life detector body 4 fixed on the connecting plate 3 upward. When the bottom of the top cover 2 is When the top cover 2 is in contact with the top of the cross plate 12, the radar life detector body 4 is exposed, which is convenient for the search and rescue work. By setting the limit assembly 8, the top cover 2 can be prevented from being overturned by external factors, thereby improving the stability of the radar life detector body 4 exposed to the outside. At the end of the search and rescue work, the telescopic rod 85 and the spring 851 can be squeezed by pressing the pressing plate 841 downward, so that the movable plate 84 can be moved downward, and the hinged rod 83 hinged on the movable plate 84 can make the pawl 82 deflect around the movable shaft 821 as the center, so that the pawl 82 is separated from the ratchet 81. At this time, the top cover 2 is flipped over, and the bottom of the top cover 2 is in contact with the top of the protective box 1. Then, the pressing plate 841 is released, and the pawl 82 is tightly fitted with the ratchet 81 under the elastic force of the spring 851.
