[0031] like Figures 1-8 As shown: A novel retractable comb-tooth winnowing basket includes a winnowing basket body 1 and a handle 2. The winnowing basket body 1 is provided with comb teeth 3, and a push plate 4 is slidably sleeved on the comb teeth 3. A push seat 5 is provided inside the winnowing basket body 1. One end of the handle 2 is connected to the push seat 5. The push plate 4 and the push seat 5 are connected by a transmission component. Pushing the handle 2 downward controls the movement of the push seat 5, and the push plate 4 is pushed outward synchronously through the transmission component.

[0032] In this embodiment, the comb teeth 3 are integrally formed on the top of the winnowing basket body 1, the push plate 4 is movably disposed below the comb teeth 3, and is fitted onto the comb teeth 3 through the through groove 701 on it, so that it can move back and forth along the horizontal direction of the comb teeth 3. The push seat 5 is disposed inside the winnowing basket body 1. By connecting the push seat 5 and the handle 2, the handle 2 can play the role of controlling the push plate 4 to push, thus making it more convenient to use.

[0033] By setting a winnowing basket body 1 with comb teeth 3, and simultaneously mounting a sliding push plate 4 on the comb teeth 3 and setting a push seat 5 inside the winnowing basket body 1, the push seat 5 and the push plate 4 are connected by a transmission component, and a handle 2 for driving the push seat 5 to move up and down is connected above the push seat 5. In use, pressing down the handle 2 forces the push seat 5 to move downward, thereby driving the transmission component, which in turn drives the push plate 4 to push outward. The push plate 4 has through holes 404 that match the comb teeth 3. During the process of pushing the push plate 4 outward, impurities on the comb teeth 3 are pushed off, thereby cleaning the comb teeth 3. In the above structure, the comb teeth 3 are cleaned by pushing the push plate 4 instead of pushing the comb teeth, avoiding damage to the comb teeth caused by frequent impacts when pushing the comb teeth outward, thereby increasing the service life of the product.

[0034] like Figures 2-8As shown: The transmission assembly includes a first driving part, a driving rod 6, and push plate transmission gears 601 disposed on both sides of the driving rod 6. The push plate 4 is provided with a push plate rack 401 that meshes with the push plate transmission gear 601. The push seat 5 is provided with a push seat rack 501 on one side. The push seat rack 501 is connected to the first driving part. The driving rod 6 is also provided with a driving rod transmission gear 602 that is connected to the first driving part. In this embodiment, the driving rod 6 consists of two connecting rods connected to each other. The driving rod transmission gear 602 is fixedly mounted on one of the connecting rods. The ends of both connecting rods are integrally formed with push plate transmission gears 601. The push plate transmission gear 601 and the driving rod transmission gear 602 can move accordingly with the driving rod 6.

[0035] like Figures 2-5 As shown: The first driving part is a double gear 8, which has a first transmission tooth surface that meshes with the push seat rack 501 and a second transmission tooth surface that meshes with the drive rod transmission gear 602.

[0036] like Figures 3-4 As shown: It also includes a drive outer seat 7, in which a through groove 701 is formed. The push seat 5 can move up and down in the through groove 701. The drive outer seat 7 is provided with a gear mounting part 702. A double gear 8 is movably mounted on the gear mounting part 702 through a gear shaft. The double gear 8 is movably mounted above the through groove 701 through a gear shaft and is located on one side of the push seat rack 50 and meshes with it. The drive outer seat 7 is installed inside the scoop body 1. The drive outer seat 7 is used to assemble, place and protect various connecting parts.

[0037] By setting a push seat rack 501 on one side of the push seat 5 and a push plate rack 401 below the push plate 4, and simultaneously setting a drive rod 6 for driving and connecting the push seat rack 501 and the push plate rack 401, the push seat rack 501 meshes with a double gear 8, which in turn meshes with a drive rod transmission gear 602 set on the drive rod 7. The push plate rack 401 meshes with the push plate transmission gear 601. In use, pressing down the handle 2 drives the push seat 5 to move downward, thereby driving the double gear 8 to rotate. After the double gear 8 rotates, it drives the drive rod 6 to rotate through the drive rod transmission gear 602, which then causes the push plate transmission gears 601 located on both sides of the drive rod 6 to move. The push plate 4 is pushed outward through the cooperation of the push plate transmission gear 601 and the push plate rack 401. The above structure achieves transmission through the cooperation of gears. This transmission method will not have any jamming, has strong overall stability, high transmission efficiency, and is easier to use.

[0038] like Figures 5-8As shown: The push plate 4 includes a pushing part 402 and a connecting part 403. The pushing part 402 is provided with a plurality of through holes 404 for fitting onto each comb tooth 3. The connecting part 403 extends into the drive outer seat 7. A guide groove 405 is provided below the connecting part 403. The guide groove 405 and the push plate transmission gear 601 are correspondingly arranged. The push plate rack 401 is arranged in the guide groove 405. By setting the guide groove 405, the stability of the connection can be increased. In this embodiment, the pushing part 402 and the connecting part 403 are integrally formed, and the connecting part 403 has two connecting strips. The guide groove 405 is arranged below the connecting strips, and the pushing part 402 protrudes upward so as to fit onto the comb tooth 3.

[0039] like Figures 3-4 As shown: The drive outer seat 7 is provided with a plurality of limiting blocks 703, and the drive rod 6 is provided with limiting rings 603 that match the limiting blocks 703. By setting the limiting blocks 703 and the limiting rings 603, the drive rod 6 can be installed more stably in the drive outer seat 7. In this embodiment, there are two limiting blocks 703 and an equal number of limiting rings 603. The limiting rings 603 are integrally formed on the drive rod 6. The limiting rings 603 have grooves, and the limiting rings 603 are engaged with the limiting blocks 703 through the grooves.

[0040] Below the push seat 5 is an elastic element for resetting the handle 2. The elastic element is located between the through groove 701 and the push seat 5. When a downward force is applied to the handle 2, the handle will drive the push seat 5 to press down. Through the movement of the transmission component, the push plate 4 is pushed out. At this time, the elastic element is in an energy storage state. When the hand is released and the downward force disappears, the elastic element will release and push the push seat 5 upward, thereby resetting the push plate 4.

[0041] like Figures 1-2 As shown: the handle 2 includes a handle portion 201 and a drive portion 202 movably connected to the handle portion 201. The winnowing basket body 1 has an opening for the handle 2 to pass through. The drive portion 202 can move up and down in the opening. The push seat 5 has a connecting groove that matches the drive portion 202. The drive portion 202 extends into the connecting groove and is fixed therein by a snap-fit ​​mechanism. In this embodiment, the handle portion 201 and the drive portion 202 are rotatably connected. The diameter of the push seat 5 is larger than the diameter of the opening. When the push seat 5 and the drive portion 202 are fixedly connected, the handle 2 can be restricted to the winnowing basket body.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
