Technical Field

[0001] This utility model relates to the field of horticultural tools technology, specifically to a horticultural seedling cutting device. Background Technology

[0002] In horticulture, seedling propagation by cuttings is a common method, and the cutting of seedlings is a crucial step before cutting. Currently, horticulturists typically use ordinary scissors and blades to manually cut seedlings. This is not only inefficient but also makes it difficult to ensure the smoothness and consistency of the cut length, easily leading to seedling damage, infection, and reduced survival rates. Furthermore, traditional cutting tools lack positioning and limiting structures, making it impossible to precisely control the cutting length according to the seedling's growth needs, resulting in poor adaptability to seedlings of different thicknesses and varieties. Additionally, manual cutting poses a safety hazard of being cut by the blade.

[0003] Therefore, there is an urgent need for a horticultural seedling cutting device that can achieve precise positioning, rapid cutting, and safe operation to solve the above-mentioned problems in the existing technology. Utility Model Content

[0025] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0026] like Figure 1-6 As shown, a horticultural seedling cutting device includes a cutting body 1, a collar 2, a locking mechanism, and a cutting assembly 3.

[0027] In some embodiments of this utility model, such as Figure 1-3As shown, the cutting body 1 is cylindrical, with a vertical groove 11 on the back. The limiting blocks 111 at the upper and lower ends of the vertical groove 11 restrict the sliding range of the collar 2. The placement cavity 12 on the front has a rectangular cross section and is connected to the outside at the bottom. Seedlings can be inserted into the placement cavity 12 from the bottom. The size scale line 121 on the surface of the placement cavity 12 can directly read the length of the seedling, which is convenient for precise control of the cutting size.

[0028] In some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, the collar 2 is sleeved on the outside of the cutting body 1. The T-shaped slider 21 on the back slides in conjunction with the vertical slide groove 11 to ensure that the collar 2 slides smoothly in the vertical direction without circumferential rotation. The circumferential limiting block 22 on the inner side is engaged with the two side walls of the placement cavity 12, which not only provides installation support for the cutting assembly 3, but also enhances the connection stability of the collar 2.

[0029] In some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, in the locking mechanism, the screw 23 passes through the T-shaped slider 21 through the threaded through hole 25. When the handle 24 is tightened, the inner end of the screw 23 presses against the inner surface of the vertical slide groove 11, and the position of the collar 2 is locked by friction. When unlocking, the handle 24 can be loosened by rotating it in the opposite direction. The operation is flexible and convenient.

[0030] In some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, in the cutting assembly 3, the blade 31 is fixed on the blade fixing block 32, and the blade 31 is perpendicular to the surface of the placement cavity 12 to ensure a flat cutting surface; two connecting rods 33 are symmetrically inserted into the through holes of the circumferential limiting block 22, one end of which is connected to the blade fixing block 32, and the other end is connected to the pressing block 35; the return spring 34 is sleeved on the connecting rod 33, and its two ends abut against the circumferential limiting block 22 and the pressing block 35 respectively. When the pressing block 35 is pressed, the blade 31 moves into the placement cavity 12 to cut the seedlings. After being released, the return spring 34 pushes the pressing block 35 and the blade 31 to return to their original positions, completing one cutting cycle.

[0031] The usage process of this utility model is as follows: First, according to the required cutting length of the seedling, slide the collar 2 to the corresponding size scale line 121 on the placement cavity 12, and tighten the handle 24 to lock the collar 2; then, insert the seedling into the placement cavity 12 from the bottom of the cutting body 1, aligning the end of the seedling to be cut with the blade 31; finally, press the pressing block 35, which drives the blade 31 into the placement cavity 12 through the connecting rod 33, quickly cutting the seedling; release the pressing block 35, and the return spring 34 drives the blade 31 to return to its original position, allowing the cut seedling to be removed. The entire operation process is simple and quick, with high cutting precision and a smooth cut, effectively improving the efficiency and survival rate of horticultural seedling cutting propagation.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
