[0026] Dismantling and classification principle:

[0027] Dismantling of the lower nest assembly and other components

[0028] Structural features of the lower nest assembly: The lower nest assembly is composed of a lower nest body, a spring and a groove, the bottom of the lower nest body is provided with the groove, the inside of the lower nest body is provided with the spring, and the lower nest body is reduced from top to bottom. The third rib (the third rib) head is designed with protrusions on both sides, which are put into the designated clamping groove of the lower nest body, and then fixed through up-down screw rotation combination.

[0029] Dismantling process: When recycling and disassembling, only the screw thread of the lower nest assembly needs to be rotated, so that the third rib and the lower nest body can be directly separated up and down. This design avoids the risk of scratching caused by traditional steel wire connection, and separates the lower nest assembly and the third rib (the third rib) from the overall structure, which is convenient for subsequent classification.

[0030] Dismantling of the handle assembly and the middle rod

[0031] Structural features of the handle assembly: The handle assembly comprises a handle body, a plug and a button, the tail of the middle rod is provided with a plurality of mounting holes, the handle body is detachably mounted on the middle rod through the plug, and the protrusion in the inside of the button is matched with the groove at the bottom of the lower nest body.

[0032] Dismantling process: When the ribs are retracted, the lower nest assembly is connected to the handle assembly, at this time, the button protrusion is clamped into the groove of the lower nest body for fixation. When disassembling, press the double-foot plug opposite to the insertion of the middle rod in the handle to remove the plug, so that the handle assembly can be separated from the middle rod, and then the handle assembly and the middle rod are separated.

[0033] The parts are classified according to the fact that the fixing ring, the lower nest, the handle and the button are made of plastic material, and the middle rod, the first umbrella rib, the second umbrella rib and the third umbrella rib are made of metal material or glass fiber material. After the above-mentioned disassembly and separation operation is completed, the parts made of plastic material can be classified into one category, and the parts made of metal material or glass fiber material can be classified into another category, so that the classification of different materials is realized according to needs, recycling is facilitated, and the purpose of environmental protection is achieved.

[0034] The above embodiments are only used for describing the present application, rather than limiting the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions belong to the scope of the present application, and the patent protection scope of the present application should be defined by the claims.
