At this time, the two arc plates 6 squeeze the spring 27, and make a side plate 19 close to the rectangular frame 2 5 correspond to the notch 9. At this time, the rectangular frame 2 5 will not be stuck when it is turned over. When the side plate 19 enters the inside of the notch 9, the two arc plates 6 are released. At this time, the two arc plates 6 are close to each other under the elastic force of the spring 27, and the two arc plates 6 drive the two side plates 19 to enter the inside of the groove 3 11 and are blocked by the baffle 10, so that the rectangular frame 2 5 and the rectangular frame 1 3 are connected together;

[0047] When carrying the device, the user holds the handle 28 and lifts it upwards, the handle 28 drives the horizontal plate 18 to move upwards, and due to the arrangement of the long plate 25 and the strip groove 23, the horizontal plate 18 moves vertically upwards together with the horizontal plate 20, the sliding rod 21 and the limiting column 17 are lifted to the top of the arc plate 6, and the two insertion rods 26 respectively enter the corresponding insertion holes 22 to ensure that the two arc plates 6 will not separate, and the lateral insertion of the long plate 25 and the strip groove 23 can ensure that the two arc plates 6 will not separate easily after being close to each other, thereby ensuring the stability of the device.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
