DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides Figure 1-4 A portable weed cutter is shown, comprising a weed guard 1 and a fixed end 6 mounted on the upper end of the weed guard 1;
[0024] The left end outer wall of the fixed end 6 is fixedly connected with the driving motor 4, and the driving motor 4 is electrically connected to the external power supply;
[0025] The outer wall of the lower end of the driving motor 4 is drivingly connected with a blade 3;
[0026] The upper end of the fixed end 6 is rotatably connected with an adjusting rod 5, a sliding sleeve 8 is fixedly connected to the outer wall of the right end of the adjusting rod 5, a sliding rod 10 is slidably connected inside the outer wall of the right end of the sliding sleeve 8, a handle 12 is fixedly connected to the right end of the sliding rod 10, and a battery 13 is fixedly connected to the center of the outer wall of the lower end of the handle 12 to power the drive motor 4. When performing a weeding operation, the battery 13 is first fully charged, and then the handle 11 and the handle 12 are held by hand, and the battery 13 will power the drive motor 4, and the drive motor 4 will drive the blade 3 to rotate at a high speed, and the blade 3 is driven to move by the hand-held handle 11 and the handle 12, and the high-speed rotating blade 3 will cut the grass that contacts the blade 3;
[0027] A fixing frame 2 is provided on the outer wall of the lower end of the grass guard plate 1, and a connecting rod b22 is fixedly connected between the inner walls at the left and right ends of the fixing frame 2. A plurality of fixing rods 14 are fixedly connected to the outer walls of the lower ends of the fixing frame 2 and the connecting rod b22 at equal intervals, and a tip 15 is fixedly connected to the outer walls of the lower ends of the plurality of fixing rods 14 to contact hard objects in the lawn. When performing lawn weeding operations, the blade 3 is driven to move by holding the handle 11 and the grip 12, and the fixing rod 14 with the tip 15 can be inserted into the lawn for exploration. When the tip 15 and the fixing rod 14 contact hard objects in the lawn, the tip 15 and the fixing rod 14 will shake the hard objects away under the vibration of the driving motor 4. The hard objects that cannot be shaken away will prevent the tip 15 and the fixing rod 14 from moving, so that the staff can find the hard objects and clean them up or bypass them.
[0028] like Figure 3 As shown, a plurality of fixing holes 18 are equidistantly arranged on the front end outer wall of the fixing frame 2, and fixing screws 19 are arranged inside the plurality of fixing holes 18 and penetrate backward into the inside of the grass guard board 1 to fix the fixing frame 2 and the grass guard board 1 together. The fixing screws 19 can be unscrewed from the fixing holes 18, and the fixing frame 2 can be removed to replace the blade 3.
[0029] like Figure 3 and Figure 4 As shown, grooves 17 are provided between the inner walls at the left and right ends of the fixed frame 2, and a connecting rod a20 is fixedly connected between the two grooves 17. A roller 21 is transmission-connected on the circular outer wall of the connecting rod a20 so as to move in contact with the ground. When weeding, the roller 21 can be moved in contact with the ground, so that when weeding, the force required by the hand can be reduced and the lawn can be made smoother. The roller 21 is made of stainless steel and has the ability to resist rust corrosion. When moving on the lawn after cutting, the surface of the roller 21 is stained with liquid from the grass for a long time, and rust will not affect the movement.
[0030] like Figure 1 As shown, a fixing knob 16 is fixedly connected at the center of the front end outer wall of the blade 3 to connect the blade 3 and the drive motor 4. When the blade 3 needs to be replaced, the fixing knob 16 can be removed to replace the blade 3. After the blade 3 is replaced, the fixing knob 16 can be tightened between the blade 3 again. The front end of the adjusting rod 5 is fixedly connected to an adjuster 7. By pressing the adjuster 7, the tilt of the adjusting rod 5 can be unlocked, so that the adjusting rod 5 can drive the sliding sleeve 8 to tilt up and down.
[0031] like Figure 1As shown, an adjusting knob 9 is threadedly connected between the sliding sleeve 8 and the sliding rod 10 to fix the position of the sliding rod 10 in the sliding sleeve 8. A handle 11 is adjusted at the center of the circular outer wall of the sliding rod 10, and the whole can be picked up for work by lifting the handle 11. The sliding rod 10 and the sliding sleeve 8 can be separated by rotating the adjusting knob 9 counterclockwise, and the sliding rod 10 and the sliding sleeve 8 can be tightened and fixed by rotating the adjusting knob 9 clockwise. When it is necessary to adjust the length of the sliding rod 10 between the sliding sleeve 8, the sliding rod 10 and the sliding sleeve 8 can be unlocked by rotating the adjusting knob 9 counterclockwise, so that the sliding rod 10 can be moved to an appropriate length in the sliding sleeve 8, and then the adjusting knob 9 can be rotated clockwise to fix the position of the sliding rod 10 in the sliding sleeve 8.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
