[0012] This utility model has the following beneficial effects: 1. By setting up a protective section, during installation, insert two semicircular blocks into the corresponding rectangular slots, and then pull the two handles counterclockwise within the two rectangular holes. This causes the corresponding mounting blocks to move within their respective mounting slots, allowing them to enter the left and right mounting slots respectively. This positions the two rectangular slots within their respective mounting slots, thus installing the protective cover onto the handheld lawnmower using the two semicircular blocks. The protective cover can be disassembled by performing the reverse operation, reducing installation steps and time, and improving assembly efficiency. Disassembly is also quick and easy, facilitating daily maintenance and repair, effectively preventing the protective cover from loosening or shifting, ensuring protective effectiveness, and enhancing safety during use. 2. By setting a limiting part, during installation, the two handles drive the two cylindrical cylinders to rotate counterclockwise through the two circular holes. At this time, the two cylindrical cylinders drive the two limiting blocks to move through the two sliding rods. With the cooperation of the arc surfaces of the two limiting blocks and the arc surfaces of several limiting grooves, the two limiting blocks are compressed and moved upwards. The two limiting blocks then push the two sliding rods to slide upwards on the two cylindrical cylinders, causing the two limiting blocks to move past the corresponding limiting grooves. During this process, the two sliding rods compress the corresponding two springs through the two circular rings, generating deformation and elasticity. When the two limiting blocks move to correspond to another limiting groove, under the action of the elastic force of the two springs... This causes the two limiting blocks to engage with their corresponding limiting slots. Repeatedly rotating the two handles connects the two semicircular blocks. The right-angled surfaces of the two limiting blocks and several right-angled surfaces of the limiting slots restrict clockwise rotation of the two handles. To remove the two semicircular blocks, pull the two slotted handles, which in turn move the two limiting blocks away from the limiting slots via two sliding rods. Then, rotate the two handles clockwise to disassemble the two semicircular blocks, thus removing the protective cover. This prevents the handles from rotating clockwise due to vibration during the operation of the handheld lawnmower, ensuring a stable connection of the semicircular blocks and fixing the protective cover to the handheld lawnmower, enhancing the safety and reliability of the protective device.

[0019] The limiting part 3 includes a fixing component 31, which is disposed on the top of the handheld lawnmower 111; and a limiting component 32, which is mounted on the support component 21. The limiting component 32 is located inside the fixing component 31. The fixing component 31 includes circular holes 311 respectively opened on two handles 223. A circular cylinder 312 is fixedly connected to the inner wall of each of the two circular holes 311. A sliding rod 313 passes through each of the two circular cylinders 312. A grooved handle 314 is fixedly connected to the top of each of the two sliding rods 313.

The two mounting blocks 221 then enter the left and right mounting slots 214 respectively, so that the two rectangular slots 212 are positioned within the two mounting slots 214, thereby using the two semicircular blocks 211 to prevent... The protective cover 213 is installed on the handheld lawnmower 111. It is disassembled through a process reversed from the above. During installation, the two handles 223 drive the two cylindrical cylinders 312 to rotate counterclockwise through the two circular holes 311. At this time, the two cylindrical cylinders 312 drive the two limiting blocks 322 to move through the two sliding rods 313. With the cooperation of the arc surfaces of the two limiting blocks 322 and the arc surfaces of several limiting grooves 323, the two limiting blocks 322 are compressed and move upwards. Block 322 pushes the two sliding rods 313 upwards on the two cylindrical tubes 312, causing the two limiting blocks 322 to move through the corresponding limiting grooves 323. During this process, the two sliding rods 313 deform and generate elastic force by compressing the corresponding springs 324 through the two circular rings 321. When the two limiting blocks 322 move to correspond to the limiting grooves 323 at another location, the elastic force of the two springs 324 causes the two limiting blocks 322 to be inserted into the corresponding limiting grooves 323, and this process is repeated. By rotating the two handles 223, the two semicircular blocks 211 are connected. Under the action of the right-angled surfaces of the two limiting blocks 322 and the right-angled surfaces of the limiting grooves 323, the clockwise rotation of the two handles 223 is restricted. When it is necessary to remove the two semicircular blocks 211, by pulling the two grooved handles 314 respectively through the two sliding rods 313, the two limiting blocks 322 are moved away from the several limiting grooves 323. Then, by rotating the two handles 223 clockwise, the two semicircular blocks 211 are disassembled, thereby removing the protective cover 213.
