Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present invention: a grass collection box suspension and storage mechanism for a lawn mower and a lawn mower, including a housing 1. A cavity 2 is opened at the right end of the middle part of the housing 1. A first installation groove 3 is opened in the middle of the inner bottom wall of the cavity 2. A fixed motor 4 is arranged inside the first installation groove 3. The bottom end of the fixed motor 4 is fixedly connected to a fixed plate 5. The output end of the fixed motor 4 is fixedly connected to a threaded rod 6. The inner side wall of the cavity 2 is slidably connected to a grass collection box body 7. The middle part of the inner bottom wall of the grass collection box body 7 is fixedly connected to a sliding sleeve 8. A threaded ring 10 is opened on the inner side wall of the sliding sleeve 8. The top end of the grass collection box body 7 is hinged to a grass collection box cover 11. The threaded rod 6 is threadedly connected to the inner side wall of the threaded ring 10. Adjustment components 9 are arranged near the edges at the left and right ends of the housing 1; two telescopic push rods 23 are fixedly connected to the right end of the housing 1. The other ends of the two telescopic push rods 23 are fixedly connected to an anti-slip grip 24;

[0033] Specifically: Two telescopic push rods 23 are fixedly connected to the right end of the housing 1. These two telescopic push rods 23 enable the user to shorten the telescopic push rods 23 after the operation is completed, thereby reducing the space required for storage equipment. At the same time, an anti-slip grip 24 is fixedly connected to the other end of the telescopic push rod 23. This anti-slip grip 24 adopts an ergonomic design, enabling the user to maintain a comfortable gripping posture during long-term operation, reducing fatigue. At the same time, the surface of the anti-slip grip 24 uses an anti-slip material, ensuring a stable gripping feeling under various weather conditions and improving the safety of operation.

[0034] Reference Figure 2 、 Figure 3 and Figure 4 ,The adjusting assembly 9 includes a plurality of sliding grooves 901, and the plurality of sliding grooves 901 are all opened at the left and right ends of the casing 1 near the edge. A plurality of uniformly distributed positioning grooves 902 are opened on the adjacent side of the plurality of sliding grooves 901. Fixing grooves 903 are opened at both the left and right ends of the casing 1. Fixed blocks 904 are fixedly connected to the inner side walls of the plurality of fixing grooves 903. Spring 905 is fixedly connected to the far end of each of the plurality of fixed blocks 904. The other ends of the plurality of springs 905 are fixedly connected with hooks 906; A connecting shaft 12 is slidably connected to the inner side wall of the left sliding groove 901, and low-resistance moving wheels 13 are fixedly connected to the front and rear ends of the two connecting shafts 12;

[0035] Specifically: Special fixing grooves 903 are provided at both the left and right ends of the casing 1. These fixing grooves 903 can provide installation positions for the fixed blocks 904. The function of these fixed blocks 904 is to provide a stable support point to facilitate the connection of the spring 905. The presence of the spring 905 makes the structure have a certain elasticity, and hooks 906 are fixedly connected to the other ends of each spring 905. The function of these hooks 906 is to fix and lock the connecting shaft 12 to ensure that the connecting shaft 12 will not shift easily during use.

[0036] Reference Figure 2 、 Figure 4 and Figure 5 ,A second installation groove 14 is opened in the middle of the casing 1, and a connection cavity 15 communicates with the middle of the inner bottom wall of the second installation groove 14; A driving motor 16 is fixedly connected to the inner bottom wall of the second installation groove 14, and a driving shaft 17 is fixedly connected to the output end of the driving motor 16; A cutter 18 is fixedly connected to the lower middle part of the driving shaft 17, a limiting block 19 is fixedly connected to the bottom end of the driving shaft 17, and a cutter head protective shell 20 is fixedly connected to the inner side wall of the connection cavity 15; A heat dissipation fan 21 is fixedly connected to the middle part of the inner side wall of the second installation groove 14, and a partition net 22 is hinged to the top end of the second installation groove 14.

[0037] Specifically: The output end of the drive motor 16 is fixedly connected to a drive shaft 17. The lower part in the middle of the drive shaft 17 is fixedly connected to a cutter 18. The drive motor 16 drives the cutter 18 to perform specific cutting tasks. At the same time, at the bottom end of the drive shaft 17, a limit block 19 is fixedly connected to ensure that the cutter 18 does not slip during movement. In addition, on the inner side wall of the connection cavity 15, a cutter head protective shell 20 is connected to protect the cutter 18 from external interference and damage during operation. At the same time, in the middle position of the inner side wall of the second installation groove 14, a cooling fan 21 is fixedly connected. Its main function is to provide effective heat dissipation for the drive motor 16 to ensure that the drive motor 16 will not be damaged due to overheating during long-term operation. Finally, at the top position of the second installation groove 14, a partition net 22 is hinged. Its main function is to prevent debris and sundries generated during cutting from splashing into the cooling fan 21, thereby protecting the normal operation of the cooling fan 21.

[0038] Working principle: The device adjusts the connection shaft 12 to different heights by opening sliding grooves 901 at the left and right ends of the housing 1 and opening a plurality of positioning grooves 902 on the sliding grooves 901, so that the device can adapt to different mowing requirements. By setting springs 905 on the fixed blocks 904 and fixing hooks 906 at the other ends of the springs 905, the function of these hooks 906 is to fix and lock the connection shaft 12 to ensure that the connection shaft 12 will not shift easily during use. At the same time, low-resistance moving wheels 13 are fixedly connected to both the front and rear ends of the connection shaft 12. These low-resistance moving wheels 13 can reduce the friction during movement and improve the operating efficiency of the lawn mower. At the same time, by opening a cavity 2 at the right end in the middle of the housing 1 and providing a grass collection box body 7 inside the cavity 2, and opening a first installation groove 3 at the bottom end of the cavity 2 and fixing a fixed motor 4, a threaded rod 6 is fixed to the output end of the fixed motor 4, and the threaded rod 6 rotates inside a sliding sleeve 8 fixed inside the grass collection box body 7. Thus, by controlling the forward and reverse rotation of the fixed motor 4, the storage and release of the grass collection box body 7 can be realized. And the grass collection box body 7 is arranged above the lawn mower, which reduces the center of gravity of the lawn mower and effectively improves the operation stability. At the same time, at the top of the grass collection box body 7, a grass collection box cover 11 is connected by a hinge. This cover 11 can be conveniently opened and closed to facilitate the user to clean the inside of the grass collection box body 7 during use.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
