[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-6 As shown, a lawnmower includes a main unit 2, a hand handle 1 on the main unit 2, a protective cover 3 at the bottom of the main unit 2, a cutting blade 4 inside the protective cover 3, the cutting blade 4 being fixedly connected to the output end of the main unit 2, first mounting holes 31 on both sides of the protective cover 3, and second mounting holes 32 on both sides of the top of the protective cover 3, and detachable wheels 5 can be installed in both the first mounting holes 31 and the second mounting holes 32. The protective cover 3 has first mounting holes 31 on both sides and second mounting holes 32 on both sides of the top. A walking wheel 5 can be detachably installed in both the first mounting holes 31 and the second mounting holes 32. In the mowing state, the walking wheels 5 are located on both sides of the protective cover 3, perpendicular to the ground. Mowing can be performed by pushing the handheld handle 1. The handheld handle 1 also has a first adjustment position 11 and a second adjustment position 12. The first adjustment position 11 is used to adjust the axial length of the handheld handle 1, and the second adjustment position 12 is used to adjust the angle between the handheld handle 1 and the main unit 2. The first adjustment position 11 and the second adjustment position 12 are prior art, with publication number CN217825984U. When the lawnmower is adjusted to the trimming position, turn the travel wheels 5 to remove them from both sides of the protective cover 3, and then install them in the second mounting holes 32 on both sides of the top of the protective cover 3. At this time, the travel wheels 5 are parallel to the ground. Then, rotate the lawnmower with the travel wheels 5 installed 90 degrees so that the travel wheels 5 are perpendicular to the ground again, which is the trimming position. The advantage of this application is that by changing the position of the travel wheels 5 in the first mounting hole 31 and the second mounting hole 32, the lawnmower can achieve the function of both mowing and trimming. In order to strengthen the structural strength of the protective cover 3, a reinforcing structural component 7 is also provided inside the protective cover 3. The lawnmower of this application has complete functions and has broad application prospects.

[0020] Example 2 like Figures 1-6As shown, the walking wheel 5 includes a shaft 51 with at least partial threads, a wheel body 53 rotatably mounted on the shaft 51, and a tensioning disc 52 on one side of the wheel body 53. The tensioning disc 52 is fixedly connected to the shaft 51. Nuts 33 are embedded in the first mounting hole 31 and the second mounting hole 32 to facilitate the disassembly and installation of the walking wheel 5 with the first mounting hole 31 and the second mounting hole 32 on the protective cover 3. During installation, it is only necessary to turn the tensioning disc 52, which drives the shaft 51 to rotate, thereby realizing the threaded connection between the shaft 51 and the first mounting hole 31 and the second mounting hole 32. The walking wheel can then be installed on the side or top of the protective cover 3, thus enabling the lawnmower to be in the mowing or trimming state. Several first mounting holes 31 are provided, and the several first mounting holes 31 are distributed along the height direction of the protective cover 3. When the lawnmower is in the mowing state, the first mounting holes 31 at different heights are installed by the trimming wheels to realize the distance between the cutting blade 4 in the lawnmower and the ground, thereby realizing the control of the depth of mowing. Several second mounting holes 32 are provided, and the several second mounting holes 32 are distributed along the diameter direction of the protective cover 3. When the lawnmower is in the trimming state, the walking wheels 5 are installed on the second mounting holes 32 at different positions on the top of the protective cover 3. When the lawnmower is rotated 90 degrees, the distance between the cutting blade 4 and the ground can be controlled to avoid the outer diameter of the cutting blade 4 being too close to the ground and causing damage to the cutting blade 4. The center line of the first mounting hole 31 is perpendicular to the center line of the second mounting hole 32, and the center line of the second mounting hole 32 is perpendicular to the ground. In this way, no matter whether the walking wheel 5 is installed in the first mounting hole 31 or the second mounting hole 32, the walking wheels 5 on both sides will not be inward or outward, which can ensure the smooth movement of the lawnmower. The protective cover 3 is also provided with a limit support 6. There are two limit supports 6. Both ends of the limit support 6 are fixed to the inner wall of the protective cover 3. The limit support 6 protects the cutting blade 4 on the one hand, and limits the shaft 51 of the traveling wheel 5 on the other hand, so as to prevent the shaft 51 from contacting the cutting blade 4 when it is threaded on the protective cover 3. The limiting support 6 includes a first limiting part 61 and a second limiting part 62. The first limiting part 61 corresponds to the first mounting hole 31. The first limiting part 61 is used to limit the axle 51 of the traveling wheel 5 to avoid contact between the axle 51 and the cutting blade 4 when the axle 51 of the traveling wheel 5 is installed in the first mounting hole 31. The second limiting part 62 corresponds to the second mounting hole 32. The second limiting part 62 is used to limit the axle 51 of the traveling wheel 5 to avoid contact between the axle 51 and the cutting blade 4 when the axle 51 of the traveling wheel 5 is installed in the second mounting hole 32. The protective cover 3 is also equipped with a reinforcing structural component 7. The reinforcing structural component 7 is either triangular or rectangular. The reinforcing structural component 7 includes a reinforcing tube 71, which is fixed to the inner wall of the protective cover 3. Three reinforcing tubes 71 are provided, and the three reinforcing tubes 71 form a triangular structure to improve the structural strength of the protective cover 3.
