[0037] Specifically, the mowing rope 5 has a first fixed section 106 clamped at the bottom of the clamping buckle 103, a second fixed section 107 inserted into the clamping groove 105, and a connecting section 108 connecting the first fixed section 106 and the second fixed section 107, and the second fixed section 107 and the connecting section 108 form an angle of -2° to -15°, which further improves the reliability of the fixation of the mowing rope 5 and avoids the mowing rope 5 from flying out and causing injuries to people during the mowing process.

[0038] In addition, an insertion port 109 for inserting the mowing rope 5 is formed on the snap-in groove 105, a guide arc surface 110 is provided on the outer periphery of the insertion port 109, and a guide slope 111 is formed on the top of the snap-in buckle 103, which makes it easier to insert the mowing rope 5 and improves the user experience.

[0039] Preferably, the mowing rope 5 is inserted into the clamping slot 105 and extends out of the clamping slot 105 by a distance of 5-10 mm, thereby further improving the reliability of the installation of the mowing rope 5.

[0040] Preferably, the bottom of the blade seat 2 is formed with an indicator mark indicating the threading path, and the user can install the mowing rope 5 according to the indicator mark, which is more convenient for some new users to install.

[0041] like Figures 1 to 3As shown, further explanation of the cooperation between the lawn mower body 1 and the blade seat 2 in this embodiment is provided, wherein the lawn mower body 1 is provided with a rotating shaft 201 for driving the blade seat 2 to rotate, the rotating shaft 201 is threadedly connected with the blade seat 2, and a clamping plate 202 is slidably provided on the lawn mower body 1, and the clamping plate 202 is clamped with the rotating shaft 201 to limit the rotation of the rotating shaft 201.

[0042] When the cutter disc seat 2 needs to be disassembled, the clamping plate 202 can be used to limit the rotation of the rotating shaft 201, so that the entire cutter disc seat 2 can be rotated and the entire cutter disc seat 2 can be directly disassembled, thereby improving the convenience of disassembling the cutter disc seat 2.

[0043] Specifically, a sliding channel 203 is formed on the main body 1 of the lawn mower, and a clamping plate 202 is slidably arranged in the sliding channel 203. An elastic element 204 is arranged in the sliding channel 203. One end of the elastic element 204 abuts against the sliding channel 203, and the other end abuts against the clamping plate 202. A clamping area 205 for clamping the rotating shaft 201 and a rotating area 206 for rotating the rotating shaft 201 are formed on the clamping plate 202. A clamping section 209 is formed on the top of the rotating shaft 201. The clamping plate 202 slides to place the clamping section 209 in the clamping area 205 and limit the rotation of the rotating shaft 201.

[0044] When the cutter disc seat 2 needs to be disassembled, the clamping plate 202 can be pressed inward so that the clamping section 209 of the rotating shaft 201 is placed in the clamping area 205. After the clamping section 209 is clamped with the clamping area 205, the rotation of the rotating shaft 201 can be restricted, so that the entire cutter disc seat 2 can be rotated for disassembly. When in normal working state, the clamping plate 202 retreats under the action of the elastic element 204, and the rotating shaft 201 rotates in the rotation area 206.

[0045] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
