[0040] By adopting the above technical solution and providing the limiting rod 6, the movable plate 116 is prevented from being deflected during the movement, thereby improving its stability.
[0041] A protective ring 7 is fixedly mounted on one end of the plurality of positioning rods 105 away from the clamping plate 104 , and the protective ring 7 is made of silicone.
[0042] By adopting the above technical solution and providing the protective ring 7, it is possible to prevent the positioning rod 105 from causing wear on the interface of the circulator body 108, thereby protecting the circulator body 108.
[0043] The number of magnetic strips 1041 on the outside of the storage box 101 is four.

Symmetrically distributed fourth springs 94 are fixedly installed on both sides of the protective plate 93, and a plurality of fourth springs 94 are fixedly connected to the inner wall of the square groove 91.
[0046] By adopting the above-mentioned technical solution, when the storage box 101 is hit, the protective plate 93 is moved toward the storage box 101 by the impact force, and the protective plate 93 can squeeze the fourth spring 94 during the movement, so that the fourth spring 94 absorbs the impact force and converts it into elastic energy storage. When the external impact force disappears, the fourth spring 94 releases the elastic force, thereby weakening the impact force acting on the storage box 101 and reducing the chance of damage to the circulator body 108.
[0047] Working principle: In actual use, by rotating the opening and closing plate 104, the movable rod 103 is driven to rotate in the fixed block 102, so that the opening and closing plate 104 can be opened, and then the annular device body 108 is placed in the placement frame 107, and the opening and closing plate 104 is rotated in the opposite direction, so that the opening and closing plate 104 and the magnetic strip 1041 on the surface of the storage box 101 are fitted together, and the fixing of the opening and closing plate 104 is completed. The positioning rod 105 is provided to position the annular device body 108 to prevent the annular device body 108 from shaking in the storage box 101; when the annular device body 108 is to be taken out, the opening and closing plate 104 is first opened, and then the first push plate 111 is pushed toward the opening and closing plate 1 04 direction, so that the first push plate 111 pushes the annular device body 108, so that the annular device body 108 can be pushed out of the storage box 101, and the first push plate 111 can squeeze the first spring 113 when moving. When the user stops applying pressure to the first push plate 111, the first spring 113 releases the elastic force, driving the first push plate 111 to reset, which is convenient for the next use, so that the annular device body 108 located at the top of the storage box 101 can be pushed out of the storage box 101, and the second push plate 112 is pushed to move toward the opening and closing plate 104, so that the second push plate 112 pushes the annular device body 108, so that the annular device body 1 08 is pushed out of the storage box 101, and the second push plate 112 can squeeze the second spring 114 when moving. When the user stops applying pressure to the second push plate 112, the second spring 114 releases its elastic force, driving the second push plate 112 to reset, which is convenient for the next use, so that the annular device body 108 located at the bottom of the storage box 101 can be pushed out of the storage box 101; by driving the threaded rod 115 to rotate, the moving plate 116 is moved toward the opening and closing plate 104, so that the moving plate 116 pushes the multiple first push plates 111 and the second push plates 112 to move, so that the multiple annular device bodies 108 in the storage box 101 can be removed from the storage box 101. Take out; the dustproof plate 204 set can prevent dust from entering the storage box 101 through the first empty slot 117 and the second empty slot 118, and the first push plate 111 and the second push plate 112 can drive the dustproof plate 204 to move when moving, so as to prevent the dustproof plate 204 from affecting the movement of the first push plate 111 and the second push plate 112. The dustproof plate 204 can squeeze the third spring 205 when moving. When the first push plate 111 and the second push plate 112 return to their original positions, the third spring 205 releases its elastic force to drive the dustproof plate 204 to reset, thereby continuing to block the first empty slot 117 and the second empty slot 118, and preventing dust from entering the storage box 101.
[0048] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
