[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1

[0020] See also Figure 1-6A tiller blade for a micro-tiller comprises a hexagonal shaft 1 for a micro-tiller, and a connecting seat 2 is evenly arranged on the outer side of the hexagonal shaft 1 for the micro-tiller. In the figure, a protective cover 3 is arranged on the outer cover of the connecting seat 2, and the protective cover 3 is connected to the hexagonal shaft 1 of the micro-tiller through screws. Specifically, an outer flange is arranged on the cover opening of the protective cover 3, and a threaded hole is arranged on the outer flange. The corresponding threaded hole is arranged on the hexagonal shaft 1, and the protective cover 3 is connected to the hexagonal shaft through screws. The center of the connecting seat 2 is provided with a socket 4 for inserting the tiller blade body 5, the protective cover 3 is provided with an opening at the corresponding position of the socket 4, the tiller blade body 5 is inserted into the socket 4, and a stop block 17 is provided at the bottom of the socket 4. The tiller blade body 5 passes through the opening and extends outside the protective cover 3, and the connecting seat 2 is provided with a moving frame 6 on both opposite sides, and the inner side of the moving frame 6 is connected to the outer wall of the connecting seat 2 through the first spring rod 7, and the inner side of the moving frame 6 is provided with a connecting rod 8, and the inside of the connecting seat 2 is provided with a clamping assembly on both sides, and one end of the connecting rod 8 passes through the connecting seat 2 and is connected to one end of the clamping assembly, and the front and rear sides of the moving frame 6 are provided with a slot 9, and a transmission sheet 10 is inserted in the slot 9. The moving frame 6 is pushed to move left and right by the transmission sheet 10. Preferably, an inclined surface is provided on the upper side of the slot 9, and trapezoidal protrusions 16 are provided on the corresponding inclined surfaces on both sides of the transmission sheet.

[0021] The clamping assembly includes a cavity 11, which is opened on the inner side of the wall of the connecting seat 2. A reset spring 12 is connected to the inner wall of the cavity 11 near the mobile frame 6. A T-shaped plug 13 is connected to the reset spring 12. One end of the T-shaped plug 13 passes through the cavity 11 and extends into the inside of the socket 4. A slot 14 corresponding to the T-shaped plug 13 is provided at the connection between the tiller body 5 and the socket 4. A limiting ring 15 is sleeved at the root of the lower side of the connecting seat 1, and the bottom surface of the mobile frame 6 is slidably connected to the top surface of the limiting ring 15. Preferably: the bottom of the transmission plate 10 is connected to the top of the limiting ring through a second spring rod, and a through hole corresponding to the transmission plate 10 is provided on the top of the protective cover. The transmission plate 10 can extend from the corresponding through hole on the protective cover, and the transmission plate 10 is set as a T shape as a whole.

[0022] There are multiple connecting seats 2, which are distributed in a circle around the hexagonal axis 1 of the micro-tiller. Three of them are shown in the figure. Connecting seats 2 are set on three of the outer sides of the hexagonal axis 1, and one is set every other side. After the tiller body 5 is used for a long time, the tiller body 5 is prone to wear or damage. At this time, the operator needs to disassemble and replace the tiller body 5 to prevent the tiller body 5 from being damaged and affecting the operation of the micro-tiller. When the tiller body 5 needs to be disassembled, the operator can press the transmission plate 10 downward. The transmission plate 10 is pressed downward, which will compress the second spring rod. In the process of the transmission plate 10 being pressed and descending, the trapezoidal protrusions 16 on both sides of the transmission plate 10 will cooperate with the inclined surface on the upper side of the slot 9 to push the two moving frames 6 to move horizontally on the top of the limit ring 15 synchronously. In the process of the moving frame 6 moving, the first spring rod 7 will be stretched;

[0023] At the same time, the movable frame 6 will pull the T-shaped plug 13 to move through the connecting rod 8, so that the T-shaped plug 13 is retracted into the cavity 11, and one end of the T-shaped plug 13 is separated from the socket 14 on the lower side of the tiller body 5. At the same time, the reset spring 12 is compressed by the T-shaped plug 13. At this time, the operator can separate the tiller body 5 from the connecting seat 2 and replace the tiller body 5. When the tiller body 5 needs to be installed, the above process can be repeated.

[0024] Among them, in this case, the limit ring 15 is sleeved on the outer side of the connection to increase the stability of the connecting seat 2. A through hole corresponding to the transmission plate 10 is set on the top of the protective cover 3. The upper side of the transmission plate 10 extends out from the through hole. The operator can disassemble and install the plowing knife body 5 by pressing the upper side of the transmission plate 10. A stop block 17 is set inside the socket 4 to limit the depth of the plowing knife body 5 inserted into the socket 4. The protective cover 3 is used to protect components such as the connecting seat 2, the movable frame 6 and the transmission plate 10.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
