[0014] The aforementioned structural advantage is that by installing the screw inside the bearing housing, the screw can rotate within the bearing housing.

[0015] Preferably, a positioning sleeve is fixed to the top right side of the fixing ear and used on the screw rod, and a fastening bolt for positioning the screw rod is threaded to the right side of the positioning sleeve and abuts against the screw rod.

[0016] The aforementioned structural advantages include the ability to position the screw by moving the fastening bolt inside the positioning sleeve, so that the fastening bolt abuts against the screw, thus preventing the screw from rotating.

[0017] Preferably, the fixing ear has a threaded hole on the left side that is adapted to the screw, and the screw is threaded into the threaded hole, and the positioning sleeve is fixed on the threaded hole.

[0018] The aforementioned structural advantages include the ability to adjust the height of the fixed lugs, support rods, and wheels via a screw.

[0019] Preferably, the bolt head of the fastening bolt is fixed with a screw plate that can be used to rotate the fastening bolt.

[0020] The aforementioned structural advantages include the ability to rotate the fastening bolts more effectively via a screwdriver, eliminating the need for tools and making operation more convenient.

[0021] Preferably, the upper end of the screw is fixed with a handle for rotating the screw, and the upper left side of the inner wall of the positioning sleeve is provided with cleaning teeth for cleaning the inside of the screw groove.

[0022] The aforementioned structural advantages include the ability to rotate the screw more quickly and efficiently via the handle, saving manpower and increasing work efficiency.

[0031] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0032] like Figures 1 to 2 As shown, a quick-adjustment mechanism for the blade angle of a micro-tiller includes a micro-tiller body 1, blades 2 used for tilling the land positioned below the micro-tiller body 1, and a fixing rod 3 positioned on the right side of the micro-tiller body 1. A mounting plate 4 is fixed to the left end of the fixing rod 3, and the mounting plate 4 is fixed to the right side of the micro-tiller body 1 by fixing bolts 5. A limiting plate 6 is sleeved on the fixing rod 3, and the limiting plate 6 abuts against the fixing bolts 5. The limiting plate 6 is adapted to the fixing rod 3. Magnets 7 are provided opposite to each other on the mounting plate 4 and the limiting plate 6, and the magnets 7 attract each other. The magnets 7 are a set of magnets with opposite polarities.

[0033] like Figure 1 , Figure 3 and Figure 4As shown, a limiting sleeve 8 is fixed to the right end of the fixing rod 3. The limiting sleeve 8 and the fixing rod 3 are an integral structure, and the inside of the limiting sleeve 8 is a through groove structure. A support rod 9 is inserted into the inside of the limiting sleeve 8. A traveling wheel 10 is provided at the bottom end of the support rod 9. A fixing ear 11 is fixed to the upper end of the support rod 9. A screw 14 is rotatably installed on the top right side of the fixing rod 3, and the screw 14 is threaded into the fixing ear 11. A bearing seat 13 for installing the screw 14 is fixed to the upper right side of the fixing rod 3, and the screw 14 is rotatably installed inside the bearing seat 13. A threaded hole adapted to the screw 14 is opened on the left side inside the fixing ear 11, and the screw 14 is threaded into the threaded hole. The positioning sleeve 1 2. Fixed to the threaded hole, the upper end of the screw 14 is fixed with a handle 15 for rotating the screw 14. The top right side of the fixing ear 11 is fixed with a positioning sleeve 12 that is sleeved on the screw 14. The upper left side of the inner wall of the positioning sleeve 12 is provided with cleaning teeth 17 for cleaning the inside of the screw 14 groove. The cleaning teeth 17 can better automatically clean the debris in the groove of the screw 14, ensuring the smoothness of the screw 14 when rotating. The right side of the positioning sleeve 12 is threaded with a fastening bolt 16 that abuts against the screw 14 for positioning the screw 14. The bolt head of the fastening bolt 16 is fixed with a tightening plate for rotating the fastening bolt 16.

[0034] Advantages of this technical solution: It facilitates better adjustment of the angle of the blade 2, resulting in better tillage performance. It also allows for the positioning of the fixing bolt 5, preventing it from loosening and falling off after prolonged use, thus minimizing potential safety hazards.

[0035] Working principle: The mounting plate 4 is installed on the right side of the micro-tiller body 1 by fixing bolt 5. Then, the limiting plate 6 is moved to abut against the fixing bolt 5, and a set of magnets 7 are attracted to each other, which can position the fixing bolt 5 and prevent the fixing bolt 5 from loosening, thus avoiding potential safety hazards.

[0036] When the angle of the blade 2 needs to be adjusted, the support height of the support rod 9 also needs to be adjusted. The support height of the support rod 9 directly changes the operating angle of the tiller body 1 and the blade 2. When adjusting the height of the support rod 9, first rotate the fastening bolt 16 to separate it from the screw 14, and then rotate the screw 14 through the handle 15. At this time, the screw 14 drives the fixing ear 11, the positioning sleeve 12, the support rod 9 and the walking wheel 10 to move downward. Since the walking wheel 10 is in contact with the ground, the angle of the tiller body 1 and the blade 2 can be adjusted. After the adjustment is completed, rotate the fastening bolt 16 to abut against the screw 14 to prevent the screw 14 from rotating during use and increase the stability of the support rod 9 and the walking wheel 10 in supporting the tiller body 1 and the blade 2. The cleaning teeth 17 set in this technical solution can automatically clean the debris in the groove of the screw 14, better ensuring the smoothness of the screw 14 during rotation.
