[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Addressing the problem that current devices cannot flexibly adjust the length of their connecting rods to accommodate worker height, causing inconvenience and reduced efficiency, this example provides a lawn mower with a pushing auxiliary mechanism. Please refer to [link to example]. Figures 1-5 The embodiment provides a lawn mower with a pushing auxiliary mechanism, which can adjust the length of the connection between the handle and the mowing mechanism to suit the height of the worker for easy operation, while fixing the position of the adjustment block to prevent the adjustment device from malfunctioning. The lawn mower with the pushing auxiliary mechanism includes a connecting pipe 1, a connecting pipe 2 101, a bearing seat 102, and a rotating block 103.

The outer surface of the rubber pad 503 is fixedly connected to the inside of the groove. A reinforcing frame 505 is fixedly connected to the front of the connecting pipe 1. A reinforcing block 506 is fixedly connected to the outer surface of the connecting shaft on the front of the adjusting gear 504. A spring piece 507 is fixedly connected to the front of the reinforcing block 506. Several threaded holes are provided on the front of the reinforcing frame 505. The spring piece 507 is located on the front of the reinforcing frame 505 and is threadedly connected to the front of the reinforcing frame 505 by a reinforcing bolt 508.

[0027] In this embodiment, rotating the adjusting block 5 drives the adjusting gear 504 to rotate, thereby moving the rack 501 and the connecting pipe 101 to adjust the length to suit the worker's height for easy operation. The rubber pad 503 can reduce the impact of vibration generated during equipment operation on the rack 501 and reduce the wear of the tooth patterns between the rack 501 and the adjusting gear 504 caused by vibration. The size of the gap between the spring piece 507 and the reinforcing block 506 is controlled by the reinforcing bolt 508 so that the spring piece 507 can fit tightly against the front of the reinforcing frame 505, thereby fixing the position of the adjusting block 5 and preventing the adjusting device from failing.

[0028] Example 2: Based on Example 1, please refer to... Figures 1-5 It allows for quick replacement of the handle and blade, and the distance between the blade and the ground can be adjusted to adapt to different working requirements. A handle 4 is slidably connected to the end of connecting pipe 2 101 away from connecting pipe 1. A threaded hole is provided on the front of connecting pipe 2 101, and a fixing bolt 401 is threadedly connected to the front of connecting pipe 2 101.

[0029] In this embodiment, the appropriate handle 4 can be quickly replaced, and the anti-slip pad 402 can reduce the possibility of workers accidentally dropping their hands due to vibration during work, thus improving safety. The grass-cutting motor 2 drives the rotating shaft 203 to rotate, thereby driving the blade head 204 to rotate to complete the grass-cutting work. The appropriate blade head 204 can be quickly replaced by the mounting bolt 205, improving work efficiency. The cylinder 3 drives the connecting frame 301 to rise and fall, thereby driving the two support frames 303 to rise and fall synchronously. Finally, the distance between the blade head 204 and the ground can be adjusted to adapt to different work requirements.

[0030] Working principle: Rotating the adjusting block 5 drives the adjusting gear 504 to rotate, thereby moving the rack 501 and the connecting pipe 101 to adjust the length to suit the worker's height for easy operation. The rubber pad 503 can reduce the impact of vibration generated during equipment operation on the rack 501 and reduce the wear of the tooth patterns between the rack 501 and the adjusting gear 504 caused by vibration. The size of the gap between the spring piece 507 and the reinforcing block 506 is controlled by the reinforcing bolt 508 so that the spring piece 507 can fit tightly against the front of the reinforcing frame 505, thereby fixing the position of the adjusting block 5 and preventing the adjusting device from failing. The system allows for quick replacement of the appropriate handle 4, and the anti-slip pad 402 reduces the possibility of workers accidentally dropping their hands due to vibration during operation, thus improving safety. The grass-cutting motor 2 drives the rotating shaft 203 to rotate, which in turn drives the blade 204 to rotate to complete the grass-cutting work. The installation bolt 205 allows for quick replacement of the appropriate blade 204, improving work efficiency. The cylinder 3 drives the connecting frame 301 to rise and fall, which in turn drives the two support frames 303 to rise and fall synchronously. Finally, the distance between the blade 204 and the ground can be adjusted to adapt to different work requirements.
