[0021] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0022] Example 1:

[0023] like Figure 1-4 As shown, the lawn mower with a working head quick-disassembly structure of the present invention includes a lawn mower body 1, a disassembly component 2 is fixed to the bottom surface of the lawn mower body 1, and an adjustment component 3 is fixed to the side surface of the lawn mower body 1, the disassembly component 2 includes a connecting block 201 fixed to the connecting shaft of the lawn mower body 1, and an annular block 202 is fixed to the bottom surface of the connecting block 201, a connecting cylinder 203 is fixed to the side surface of the annular block 202, and a limiting ring 204 is fixed to the inner wall of the connecting cylinder 203, a convex column 205 is movably connected to the interior of the connecting cylinder 203, and a spring 206 is provided inside the surface of the connecting cylinder 203, a bearing 207 is fixed to the surface of the connecting cylinder 203, and a rotating shaft 208 is fixed to the surface of the bearing 207, and a connecting rope 209 is fixed to the surface of the rotating shaft 208.

[0024] like Figure 1-4 As shown, the internal part of the annular block 202 is movably connected to a movable column 210, and a working head body 211 is fixed on the surface of the movable column 210. A circular hole 212 is opened on the bottom surface of the working head body 211, and a cutting blade 213 is installed on the surface of the working head body 211 through a rotating shaft.

[0025] like Figure 1-4 As shown, the boss 1 205 sequentially passes through the annular block 202 and the movable post 210 and extends to the interior of the movable post 210 , and the surface of the spring 1 206 contacts the surface of the boss 1 205 .

[0026] like Figure 1-4 As shown, the connecting rope 209 forms a fixed structure with the boss 1 205 through bolts, and the surface of the limiting ring 204 contacts the surface of the spring 1 206 .

[0027] like Figure 1-4 As shown, a protective plate 4 is fixed on the surface of the lawn mower body 1 , and a connecting member 5 is fixed on the surface of the lawn mower body 1 .

[0028] During implementation, if the working head body 211 needs to be disassembled, first rotate the rotating shaft 208, and the rotating shaft 208 drives the connecting rope 209 to slide, and the connecting rope 209 drives the boss 205 to slide, thereby facilitating the separation of the boss 205 from the movable column 210, and sliding the working head body 211, the working head body 211 can be disassembled. The disassembly is simple because a circular hole 212 is opened on the surface of the working head body 211, which is convenient for users to disassemble.

[0029] Example 2:

[0030] like Figure 1-4 As shown, based on the first embodiment, the present invention provides a technical solution: the adjustment component 3 includes a U-shaped block 301 fixed to the surface of the connecting member 5, and a sleeve 302 is fixed to the surface of the U-shaped block 301, a rotating block 303 is installed on the inner surface of the U-shaped block 301 through a rotating shaft, and a plurality of groups of limiting holes 304 are provided on the surface of the rotating block 303, and an operating rod 305 is fixed to the surface of the rotating block 303.

[0031] like Figure 1-4 As shown, a sliding groove 306 is provided on the surface of the sleeve 302 , and a second spring 307 is provided inside the sleeve 302 . A second protrusion 308 is movably connected inside the sleeve 302 , and a sliding post 309 is fixed on the surface of the second protrusion 308 .

[0032] like Figure 1-4 As shown, the surface of the sliding column 309 contacts the inner wall of the sliding groove 306 , and the surface of the second protrusion 308 fits the inner wall of the limiting hole 304 .

[0033] During implementation, when the rotating block 303 needs to be adjusted, the sliding column 309 is used to slide the sliding column 309, which drives the second boss 308 to slide, so that the second boss 308 is separated from the surface of the rotating block 303 and the limiting hole 304. The rotating block 303 is rotated to a suitable position, and the angle of the operating rod 305 can be adjusted.

[0034] The advantages of this technical solution in practical applications include but are not limited to the following:

[0035] 1. The disassembly assembly 2 is provided with a connecting tube 203 and a boss 1 205. When the operator rotates the rotating shaft 208, the rotating shaft 208 can drive the connecting cable 209 and the boss 1 205 to slide, thereby separating the boss 1 205 from the movable column 210. The working head body 211 can be slid and disassembled, making disassembly simple.

[0036] 2. By providing a sleeve 302 and a second boss 308 inside the adjustment component 3, the second boss 308 is slid to separate the second boss 308 from the surface of the rotating block 303 and the limiting hole 304, and the rotating block 303 is rotated to a suitable position to adjust the angle of the operating rod 305.

[0037] In this technical solution, the working head body 211 needs to be disassembled. First, the rotating shaft 208 is rotated, and the rotating shaft 208 drives the connecting cable 209 to slide, and the connecting cable 209 drives the boss 1 205 to slide, so as to facilitate the separation of the boss 1 205 from the movable column 210. The working head body 211 is slid, and the working head body 211 can be disassembled. The disassembly is simple. Since a circular hole 212 is opened on the surface of the working head body 211, it is convenient for users to disassemble. When the rotating block 303 needs to be adjusted, the sliding column 309 is sliding, and the sliding column 309 drives the boss 2 308 to slide, so that the boss 2 308 is separated from the surface of the rotating block 303 and the limiting hole 304. The rotating block 303 is rotated to a suitable position, and the angle of the operating rod 305 can be adjusted.

[0038] The above are merely exemplary embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. That is, any equivalent variations and modifications made in accordance with the teachings of the present disclosure are still within the scope of the present disclosure.
