Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Example 1

As shown in the figure 1-2, an environment-friendly grass trimmer comprises a fixed ring 1 fixedly connected with a holding rod, a rotating ring 2 which can freely rotate along the axis is rotatably connected outside the fixed ring 1, concretely, an upper step with an upward opening is arranged on the fixed ring 1 along the circumferential direction of the outer ring, a lower step with a downward opening is arranged on the rotating ring 2 along the circumferential direction of the inner ring, the upper end of the upper step is provided with an annular limiting bulge, a limiting groove matched with the limiting bulge is arranged on the lower side wall of the lower step, the positions of the fixed ring 1 and the rotating ring 2 can be further limited under the action of the limiting bulge and the limiting groove, the rotating ring 2 is driven by a driving motor, concretely, the driving motor can be horizontally arranged, the rotating ring 2 is driven to rotate around the fixed ring 1 by the transmission mode of a helical gear, a grass trimming rope 21 is fixedly connected on the outer side wall of the rotating ring 2, the fixed ring 1 is fixedly connected with a sliding rod 11 along the diameter direction, the sliding rod 11 is made of non-ferromagnetic materials, the sliding rod 11 is provided with a grass mowing mechanism 12, and the rotating ring 2 is fixedly connected with a permanent magnet 22 for driving the grass mowing mechanism 12.

The grass mowing mechanism 12 comprises a plurality of permanent magnet rings 121, the permanent magnet rings 121 are sequentially sleeved on the sliding rod 11 in a sliding mode, like poles of two adjacent permanent magnet rings 121 repel each other, springs 122 are fixedly connected to two ends of each permanent magnet ring 121, and the other ends of the springs 122 are fixedly connected with the inner side wall of the fixing ring 1.

It should be noted that, the number of the permanent magnets 22 is two, and the magnetic poles of the two permanent magnets 22 are opposite, and the two permanent magnets 22 are provided, so that the frequency of the permanent magnets 22 sweeping the sliding rod 11 is increased, thereby improving the rhythm frequency of the spring 122, and further improving the grass stem trimming effect of the spring 122.
