[0015] The utility model will be further described in connection with the embodiments shown in the drawings:

[0016] As Figures 1-5As shown, an adjustable switch for high-efficiency and environmentally friendly lithium-ion garden tools is installed between a sleeve 1 and a material container 3. The sleeve 1 is fitted onto the air outlet of a fan. The material container 3 is used to store materials, and its lower end has a material inlet 4 for discharging materials. The upper end of the sleeve 1 has a feed inlet 5 that connects to the inside of the sleeve 1 and is directly opposite the material inlet 4. An installation ring 14 is fixedly installed at the upper end of the mounting tube 7 for insertion into the lower end of the material container 3. A slide rail 17 is provided inside the mounting ring 14, located directly above the feed inlet 5. Two cover plates 18 are movably installed inside the slide rail 17, and an adjustment switch is movably installed above the cover plates 18. An adjusting plate 19 is provided to adjust the distance between the two cover plates 18. The adjusting plate 19 has a through hole 27 in the center for inserting the material inlet 4. The two cover plates 18 are symmetrically arranged above the feed inlet 5. The adjusting plate 19 is rotatably arranged in the mounting ring 14. The adjusting plate 19 has two slots 20 that penetrate the adjusting plate 19 vertically. The slots 20 are arc-shaped, and the distance between the slot 20 and the center of the adjusting plate 19 gradually increases from one end to the other. The two slots 20 are symmetrically arranged on the adjusting plate 19 with the center of the adjusting plate 19 as the center. A fixing rod 21 is fixedly provided on the cover plate 18 for inserting into the slot 20. With two symmetrically arranged slots 20, the cover plate 18 can only move along the length of the slide 17. By rotating the adjusting plate 19, the positions of the two cover plates 18 can be adjusted simultaneously, allowing them to move synchronously along the length of the slide 17. Adjusting the distance between the two cover plates 18 controls the material feeding speed, which is relatively convenient. When the distance between the two cover plates 18 is small, the feeding speed is slow, and larger diameter seeds cannot enter the sleeve 1, enabling the sieving of seeds by size. The mounting ring 14 has an opening 22 on its side wall, which connects to the inside of the mounting ring 14. A lever 23 is fixedly installed on the side wall of the adjusting plate 19, located within the opening 22. The lever 23 has an anti-slip groove 24, which allows the adjusting plate 19 to be rotated easily. When the adjusting plate 19 rotates 50 degrees, the fixing rod 21 moves from one end of the slot 20 to the other end, changing the cover plate 18 from a closed state to a fully open state.

[0017] The lower end of the material bin 3 has a cavity 25 for installing the aforementioned adjusting plate 19, and the aforementioned material inlet 4 is located at the center of the cavity 25. Through the cavity 25, after the material bin 3 is installed, the cover plate 18 is located between the material inlet 4 and the feed inlet 5, and the cover plate 18 abuts against the lower part of the material inlet 4.

[0018] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not intended to limit the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or variations of the description are still within the protection scope of the present application.
