[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a lawn mowing device, including a frame 1, a frame 2, a limiting groove 201, a fixing groove 202, a limiting groove 203, a motor 3, a support plate 4, a limiting column 401, a roller 402, a support rod 1 403, a support rod 2 404, a limiting block 405 and a grass baffle 5. The right side of the frame 1 is connected to the left side of the frame 2, the middle right position of the inner side of the frame 2 is connected to the supporting plate 4, the motor 3 is connected to the top of the supporting plate 4, and the middle right position of the frame 2 is provided. There are limit grooves 1 201 and 203, and a fixing groove 202 is provided at the bottom of the frame 2, three rollers 402 are installed on the left and right sides of the support plate 4, and three limit columns 401 are placed on the left and right sides of the top of the support plate 4 and are connected and fixed to the rollers 402, the left and right sides of the bottom of the support plate 401 are connected to the top of the support rod 1 403, the bottom of the support rod 1 403 is connected to the top of the support rod 2 404, a limit block 405 is installed at the right rear position of the bottom of the support plate 4, and a grass guard plate 5 is provided at the bottom right side of the frame 2.

[0022] As the first embodiment of the utility model: the grooves provided on the left and right sides of the support plate 4 are larger than the roller 402, and the positioning holes provided on the top of the support plate 4 are slightly larger than the limiting column 401. This design plays a role in fixing the roller 402, so that the roller 402 can rotate inside the groove. The rollers 402 connected on the left and right sides of the support plate 4 are connected to the limiting groove 1 201 and the limiting groove 2 203. Under the action of the roller 402, this design can pull the support plate 4 out of the frame 2 2, which is convenient for repairing the motor 3 and other components. The limiting block 405 is connected to the slot provided on the support plate 4 and fixed at its bottom by bolts. This design plays a role in fixing the limiting block 405. A positioning groove is provided at the bottom of the limiting groove 203, and the positioning groove is larger than the limiting block 405. This design plays a role in limiting when pulling the support plate 4, preventing the support plate 4 from detaching from the frame 2 2. The bottom of the support rod 1 403 is provided with an internal thread, which meshes with the external thread provided on the support rod 2 404. This design allows the support rod 2 404 to shorten and stretch. The overall length, width and depth of the limit slots 3 provided on the left and right sides of the bottom of the support plate 4 are greater than the length, width and height of the support rod 1 403. This design allows the support plate 4 to be pushed into the inside of the frame 2 2, and the top of the support rod 1 403 is fixed to the inside of the limit slots 3 by bolts. This design plays a supporting role for the support rods 1 403 and the support rods 2 404 when the support plate 4 is pulled out. The left edge of the support plate 4 is connected to the fixed hook and fixed with the fixed column provided on the left side of the limit slot 1 201. This design allows the vibration generated when the motor 3 is working to shake the support plate 4 out of the frame 2 2, so it plays a role in fixing the support plate 4.

[0023] As the second embodiment of the utility model: due to the role of the limiting groove 1 201 and the limiting groove 203 opened in the middle position of the right side of the frame 2 in the device, the rollers 402 installed on the left and right sides of the support plate 4 are connected thereto. Under the role of the rollers 402, the support plate 4 can be pushed and pulled back and forth inside the limiting groove 1 201 and the limiting groove 203, and the limiting column 401 installed on the top of the support plate 4 plays a role in fixing the roller 402 to prevent the roller 402 from detaching from the support plate 4. The limiting block 405 installed on the bottom of the support plate 4 plays a role in limiting the support plate 4 when the frame 2 is pulled out, preventing the support plate 4 from detaching from the limiting groove 1 201 and the limiting groove 203. The support rod 1 403 and the support rod 2 404 connected to the bottom of the support plate 4 support the support plate 4. The support rod 2 404 and the support rod 1 403 are engaged with each other through threads, so that the support rod 2 404 can be shortened and extended, thereby ensuring that there is a balancing force between the support plate 4 and the ground when the motor 3 is repaired. When the support rod 2 404 is shortened, the support rod 1 403 and the limiting groove are three-phase overlapped, and the support plate 4 can overlap with the frame 2 2 without affecting its work. The fixing hook provided on the left side of the support plate 4 is clamped and fixed with the fixing column provided on the left side of the limiting groove 1 201, so that the support plate 4 will not separate from the frame 2 2 when the motor 3 is working.
