[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of a garden lawn mower, including a base frame 1, a motor 21, and an adjustment assembly. A long shaft 4 is fixedly connected inside the base frame 1, and a rolling wheel 5 is rotatably connected to the long shaft 4. An adjustment assembly is located at the top of the base frame 1, and the motor 21 is also located at the top of the base frame 1. A light shaft 22 is fixedly connected to the bottom of the motor 21 and is located inside the base frame 1. A mounting plate 23 is fixedly connected to the bottom of the light shaft 22, and a blade 24 is located at the bottom of the mounting plate 23. A fixed frame 26 is fixedly connected to the top of the base frame 1, and a sliding block 28 is slidably connected inside the fixed frame 26. A first light rod 29 is fixedly connected to the outside of the sliding block 28, and a movable bracket is rotatably connected to the first light rod 29. 212. A fixed bracket 210 is fixedly connected to the motor 21. A second guide rod 211 is fixedly connected to the outside of the fixed bracket 210. The end of the movable bracket 212 away from the first guide rod 29 is rotatably connected to the second guide rod 211. A connecting rod 213 is fixedly connected between the first guide rods 29 to move the sliding blocks 28 on both sides synchronously. By moving the two sliding blocks 28 synchronously in opposite directions inside the fixed frame 26, the opening and closing motion between the two movable brackets 212 is changed, thereby adjusting the extension length of the blade 24 above the ground, improving its adaptability and the convenience of adjusting the extension length of the blade 24, and facilitating the rapid adjustment of the extension length of the blade 24. The adjustment component rotates the worm gear. 36, causing the long rod 32 to rotate inside the protective frame 33 and the semi-circular block 31, adjusting the angle of the rotating rod 39. By aligning the through hole of the inner rod 38 with the corresponding through hole 37 of the outer frame 34, and then aligning and inserting the pin 311, the outer frame 34 and the inner rod 38 are limited and fixed, thereby completing the adjustment of the extension length of the rotating rod 39 and the rubber pad 310 to meet the user's needs and improve the adaptability of the device. The fixed frame 26 has a matching groove at the corresponding position of the sliding block 28. The sliding block 28 is slidably connected in the groove of the fixed frame 26. By the synchronous counter-movement of the two sliding blocks 28 inside the fixed frame 26, the two movable supports 2 are changed. The opening and closing motion between 12 allows adjustment of the extension length of the blade 24 above the ground, improving its adaptability and ease of adjustment. The mounting plate 23 has mounting bolts 25 threadedly connected to the inside of the blade 24. A bidirectional threaded rod 27 is rotatably connected inside the fixing frame 26, and sliding blocks 28 are threadedly connected to the outside of the bidirectional threaded rod 27. This, via the connecting rod 213, causes the sliding blocks 28 on both sides to move synchronously, thereby synchronously adjusting the extension lengths of the motor 21, optical shaft 22, mounting plate 23, blade 24, and mounting bolts 25, thus improving the device's practicality.

[0021] Please see Figure 4 - Figure 5In this embodiment, the adjustment assembly includes a semicircular block 31, which is fixedly connected to the top of the bottom frame 1. A long rod 32 is rotatably connected inside the semicircular block 31, and an outer frame 34 is fixedly connected to the long rod 32. A protective frame 33 is fixedly connected to the top of the bottom frame 1, and the long rod 32 is rotatably connected inside the protective frame 33. A worm gear 35 is fixedly connected to the long rod 32, and a worm 36 meshes with the outside of the worm gear 35. The worm 36 is rotatably connected inside the protective frame 33. A through hole 37 is provided on the outer frame 34, and an inner rod 3 is slidably connected inside the outer frame 34. 8. A rotating rod 39 is rotatably connected inside the inner rod 38. A rubber pad 310 is fixedly connected to the rotating rod 39. The rubber pad 310 is located on the inner side of the inner rod 38. A pin 311 is installed inside the through hole 37. The pin 311 is located inside the inner rod 38. An arc block 312 is slidably connected inside the pin 311. A spring 313 is fixedly connected between the arc block 312 and the pin 311. The adjusting component rotates the worm gear 36, which drives the long rod 32 to rotate inside the protective frame 33 and the semi-circular block 31, thereby adjusting the angle of the rotating rod 39. By aligning the through hole of the inner rod 38 with the corresponding through hole 37 of the outer frame 34, and then aligning and inserting the pin 311, the outer frame 34 and the inner rod 38 are fixed in place, thereby completing the adjustment of the extension length of the rotating rod 39 and the rubber pad 310 to meet the user's needs and improve the adaptability of the device. The outer frame 34 has a matching groove at the corresponding position of the inner rod 38, and the inner rod 38 is slidably connected in the groove of the outer frame 34, which limits the inner rod 38 and improves the convenience of adjusting the extension length of the rotating rod 39. Seven sets of holes 37 are provided, and the seven sets of through holes 37 are distributed on the outer frame 34 from left to right. By aligning the through hole of the inner rod 38 with the corresponding through hole 37 of the outer frame 34, and then aligning and inserting the pin 311, the outer frame 34 and the inner rod 38 are limited and fixed, improving the stability of the device. The inner rod 38 has a through hole at the corresponding position of the pin 311, and the pin 311 is located inside the through hole of the pin 311. By aligning the through hole of the inner rod 38 with the corresponding through hole 37 of the outer frame 34, the extension length of the rotating rod 39 can be easily adjusted.

[0022] When adjusting the height of the blade 24 during operation, the bidirectional threaded rod 27 is rotated inside the fixed frame 26. Sliding blocks 28 are threadedly connected to the outside of the bidirectional threaded rod 27, causing the two sliding blocks 28 to move synchronously in opposite directions inside the fixed frame 26. This alters the opening and closing motion between the two movable supports 212. The connecting rod 213 causes the sliding blocks 28 on both sides to move synchronously, adjusting the extension length of the motor 21, optical shaft 22, mounting plate 23, blade 24, and mounting bolt 25. This adjusts the extension length of the blade 24 from the ground, improving its adaptability. When adjusting the angle of the outer frame 34, the worm gear 36 is rotated, engaging with the worm wheel 35, which in turn drives the long rod. 32 rotates inside the protective frame 33 and the semi-circular block 31 to adjust the angle of the rotating rod 39. When it is necessary to adjust the extension length of the rotating rod 39, the pin 311 is pulled outward to release the limit of the outer frame 34 and the inner rod 38, so that the through hole of the inner rod 38 is aligned with the corresponding through hole 37 of the outer frame 34. Then the pin 311 is aligned and inserted to limit and fix the outer frame 34 and the inner rod 38. Through the arc-shaped design of the top of the spring 313 and the arc block 312, the pin 311 can be inserted or pulled out by force, thereby completing the adjustment of the extension length of the rotating rod 39 and the rubber pad 310. The user holds the rubber pad 310 and pushes the bottom frame 1 to move through the roller 5 to perform the grass cutting operation, so as to meet the user's needs and improve the adaptability of the device.

[0023] Through the above steps, the two sliding blocks 28 move synchronously in opposite directions inside the fixed frame 26, thereby changing the opening and closing motion between the two movable supports 212. This adjusts the extension length of the blade 24 from the ground, improving its adaptability and the ease of adjusting the extension length of the blade 24. This solves the problem of disassembling and installing the bolts of the fixed motor 21, which takes a lot of time and makes it difficult to meet the needs of rapid adjustment.
