[0002] Common lawnmowers typically use an engine as the drive mechanism and gasoline as the power source. This type of device can pollute the environment. These types of lawnmowers have relatively large cutting mechanisms, making them difficult to use in narrow areas or areas where crops are planted on both sides, and they can easily damage the crops. Other types use batteries as the power source, but they use multiple blades, which not only results in slow working efficiency, but also causes some tough grasses to get tangled in the drive shaft, causing the cutting blades to lose power. This requires regular cleaning and reduces efficiency.

[0003] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model changes the original single-blade design to a three-blade design, using a single motor to control the rotation and cutting of grass, increasing the cutting area and improving cutting efficiency. Furthermore, in the original design, grass easily tangles on the blade shaft, hindering the blade's rotation. This utility model installs an anti-tangling blade holder on the shaft above the blades, further cutting the grass that has already been cut once, resulting in a finer cut and preventing tangling.

[0015] 2. The long pole in this utility model can move longitudinally through the cooperation of the positioning ring and the positioning groove, making it convenient for people of different heights to mow the grass and ensuring that the mowing blade is parallel to the ground. Moreover, the locking pin on the steering knuckle can cooperate with the positioning hole on the positioning column to make the entire mounting box move laterally, supporting adjustment from -110 degrees to 110 degrees, which is convenient for mowing grass in narrow areas.

[0016] 3. This utility model adopts a double-safety design, namely, a battery switch is set on the battery backpack, and a motor switch is set on the handle. The mowing mechanism can only mow the grass when both switches are turned on simultaneously, avoiding accidental operation. In addition, to prevent the possibility of the mowing blade breaking in case of accident, a protective plate is installed at the bottom of the mounting box to ensure the safety of the operator.
