[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] As Figures 1 to 4 shown, for a portable and environmentally friendly mowing device, connecting rods 2 are fixedly installed on both sides of the handheld mower head 1. A fixed storage rod 4 is fixed at the end of the connecting rod 2 away from the handheld mower head 1. An adjusting rod 5 is slidably inserted at the bottom end of the fixed storage rod 4. A moving support base 6 is fixed at the bottom end of the adjusting rod 5. Two support wheels 8 are rollingly embedded at the bottom of the moving support base 6. The moving support base 6 is in rolling contact with the ground through the support wheels 8. The handheld mower head 1 is supported by the moving support base 6, the adjusting rod 5, the fixed storage rod 4, and the connecting rod 2, ensuring that a constant height is maintained between the handheld mower head 1 and the ground, ensuring that the mowing height of the trimmed lawn is consistent, and ensuring the beauty of the lawn.

[0022] Both ends of the moving support base 6 are upturned and the included angle with the ground is thirty degrees. Both ends of the moving support base 6 are made of aluminum alloy. Both ends of the moving support base 6 are upturned. When the moving support base 6 contacts a stone during the movement of the mowing device, the moving support base 6 can cause the entire mowing device to move upward, ensuring that the mowing device can smoothly pass over the stone.

[0023] A guiding hole is provided at the bottom end of the fixed storage rod 4. The top end of the adjusting rod 5 is inserted into the guiding hole. A return spring 10 is installed between the top end of the adjusting rod 5 and the fixed storage rod 4. An adjusting insertion pin 7 is detachably inserted on one side of one end of the fixed storage rod 4. A plurality of adjusting insertion holes 9 are provided at equal intervals up and down through the top end of the adjusting rod 5. The adjusting insertion pin 7 passes through the end of the fixed storage rod 4 and is slidably inserted inside one of the adjusting insertion holes 9. By changing the length dimension of the adjusting rod 5 in the fixed storage rod 4, the distance between the moving support base 6 and the fixed storage rod 4 is adjusted, thereby controlling the distance between the handheld mower head 1 and the ground.

[0024] At the bottom of the handheld lawn mower head 1, there is an adjusting socket hole 9. The top end of the adjusting socket hole 9 is inserted into the interior of the handheld lawn mower head 1 and is rotatably connected to the handheld lawn mower head 1. The adjusting socket hole 9 cannot move axially. Inside the handheld lawn mower head 1, there is a fixed motor. The output shaft end of the motor is vertically downward and is fixed to the top end of the adjusting socket hole 9. On the outer side of the bottom end of the adjusting socket hole 9, there are multiple cutting blade strips 3. The cutting blade strips 3 are distributed in a circular array around the axis of the adjusting socket hole 9. The adjusting socket hole 9 is made of plastic. The motor is used to drive the adjusting socket hole 9 and the cutting blade strips 3 on the outer side of the bottom end of the adjusting socket hole 9 to rotate at high speed, hitting the grass to break it, so as to achieve the cutting of the lawn.

[0025] Working principle: First, according to the cleaning height requirement of the lawn, adjust the height between the handheld lawn mower head 1 and the ground. When adjusting, pull out the adjusting plug pin 7 from the side of the fixed storage rod 4, and then squeeze the adjusting rod 5 into the fixed storage rod 4 so that the return spring 10 is compressed, or the return spring 10 elastically resumes and pushes the adjusting rod 5 out of the fixed storage rod 4 until the length of the adjusting rod 5 extending out of the fixed storage rod 4 meets the adjustment requirement. At this time, insert the adjusting plug pin 7 into the fixed storage rod 4 and make the end of the adjusting plug pin 7 enter the adjusting socket hole 9 where the axis of the end of the adjusting rod 5 coincides with the adjusting plug pin 7 to fix the positions of the adjusting rod 5 and the movable support seat 6. Next, the operator only needs to place the handheld lawn mower head 1 on the ground, and the support wheels 8 and the movable support seat 6 support the handheld lawn mower head 1. At this time, turn on the power of the mowing device. After the power is turned on, the operator pushes the handheld lawn mower head 1 to move on the lawn, and uses the high-speed rotating adjusting socket hole 9 and cutting blade strips 3 to clean the lawn, ensuring that the trimmed height of the lawn is consistent, ensuring the beauty of the lawn, and enabling the staff to avoid long-term arm force to support the mowing device, reducing the labor intensity of the staff and improving the mowing efficiency.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
