[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, when... Figure 1As shown, when using the plow body 1, the triangular frame plow frame 2 and the front end of the suspension bracket plate 5 are assembled with the external suspension structure via suspension pins. When the spacing between the adjustable plow bodies 4 is adjusted according to the plowing width, the plow body adjusting rod 3 is rotated with a tool to engage with the threaded engagement of the adjustable plow bodies 4, causing the adjustable plow bodies 4 to move synchronously inward or outward through the threaded engagement. When the adjustable plow bodies 4 move synchronously outward, the plowing width widens; when the adjustable plow bodies 4 move synchronously inward, the plowing width narrows. This achieves the adjustment of the adjustable plow bodies 4 according to the plowing width. Simultaneously, the threads of the plow body adjusting rod 3 and the adjustable plow bodies 4 have self-locking properties, so no additional fixing device is needed after adjustment to maintain the set plowing width. Compared to the traditional U-shaped clip fixing method, this design eliminates the need to disassemble the screws. The bolt enables rapid adjustment. When the telescopic support rod 8 is extended or retracted, the telescopic adjustment cylinder 7 is engaged with the threaded telescopic support rod 8 by rotating the tool, causing the telescopic support rod 8 to move backward or forward through the threaded engagement. When the telescopic support rod 8 moves backward, the support mechanism formed by the bearing support cylinder 6, the telescopic adjustment cylinder 7, and the telescopic support rod 8 becomes longer, causing the rear end of the suspended triangular frame plow frame 2 to flip downward. When the telescopic support rod 8 moves forward, the support mechanism formed by the bearing support cylinder 6, the telescopic adjustment cylinder 7, and the telescopic support rod 8 becomes shorter, causing the rear end of the suspended triangular frame plow frame 2 to flip upward. This covers the needs from compact transport to the maximum tillage support position, forming a three-dimensional adjustable support system to ensure the optimal force angle is maintained under different terrains.

[0031] Example 2: Unlike Example 1, the regular hexagonal prism of the plow body adjusting rod 3 can also be set as a regular heptagonal prism. This makes it necessary to use a special tool that works with the regular heptagonal prism to rotate the plow body adjusting rod 3, thus preventing non-staff members from rotating and adjusting the plow body adjusting rod 3.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal structure of the telescopic adjustment cylinder 7 can also be set as a regular heptagonal structure. This makes it necessary to use a special tool that works with the regular heptagonal structure to rotate the telescopic adjustment cylinder 7, thus preventing non-staff members from rotating and adjusting the telescopic adjustment cylinder 7.
