It should be noted that the change of the form of the garden tool does not have substantial influence on the structure and function of the present disclosure.

[0040] Please refer to Figure 1 and Figure 2 The lawn mower 100 shown in the embodiment includes a machine body 1 and at least two groups of driving devices 2. The driving devices 2 are installed on the machine body 1 to support and drive the machine body 1 to move in a working area or along a preset path to complete the work. The driving devices 2 can be provided in two groups, and the two groups of driving devices 2 are arranged on the two sides of the machine body 1. In the embodiment, the two groups of driving devices 2 are arranged as rear wheels at the rear end of the machine body 1. The machine body 1 is provided with two steering wheels 3 at the front end, and the two steering wheels 3 are arranged opposite to each other on the two sides of the machine body 1. The steering wheels 3 are used to realize the steering of the machine body 1, and the driving devices 2 are used to drive the movement of the machine body 1. In other embodiments, the two groups of driving devices can be arranged as front wheels at the front end of the machine body, or the lawn mower can include four groups of driving devices, two groups of driving devices as front wheels at the front end of the machine body, and the other two groups of driving devices as rear wheels at the rear end of the machine body. The movement of the four groups of driving devices realizes the movement of the machine body.

[0041] The driving device 2 comprises a driving mechanism 21 and a walking wheel 22 detachably mounted on the driving mechanism 21. The driving mechanism 21 drives the walking wheel 22 to rotate to realize the movement of the mower body 1. The mower 100 further comprises a mounting member 23 arranged on the mower body 1, and the driving mechanism 21 is detachably mounted on the mounting member 23 to be connected to the mower body 1. The mower 100 further comprises at least one first connecting member 24 connecting the driving mechanism 21 and the mounting member 23 to mount the driving mechanism 21 on the mower body 1, and the first connecting member 24 is configured to be separated from at least one of the driving mechanism 21 and the mounting member 23 to detach the driving mechanism 21 from the mower body 1. That is, when the first connecting member 24 is simultaneously connected with the driving mechanism 21 and the mounting member 23, the driving mechanism 21 and the mounting member 23 are kept in position relative to each other under the connection of the first connecting member 24. When the first connecting member 24 is separated from one of the driving mechanism 21 and the mounting member 23, the driving mechanism 21 and the mounting member 23 are separated from each other due to the loss of the connection of the first connecting member 24. Obviously, when the first connecting member 24 is separated from both the driving mechanism 21 and the mounting member 23, the driving mechanism 21 and the mounting member 23 are separated from each other.

[0042] When the driving mechanism 21 is to be repaired and detached, only the first connecting member 24 connecting the driving mechanism 21 and the mounting member 23 needs to be detached, so that the driving mechanism 21 is detached from the mower body 1, and the connecting member mounting the mounting member 23 on the mower body 1 does not need to be detached, so that the connection of the mower body 1 is not easy to be damaged, and the increase of the number of times of detaching the driving mechanism 21 only causes the damage of the connection of the mounting member 23, and at this time, only the mounting member 23 needs to be replaced, so that the difficulty and cost of repair are reduced.

[0043] The mounting member 23 is in the form of a disc with a hollow structure, and the hollow structure is arranged to facilitate the arrangement and installation of cables and other structures connected with the driving mechanism 21. The mounting member 23 can also be in other forms, such as a square, and the specific form of the mounting member 23 is not limited.

[0044] The second connecting piece 25 is arranged between the mounting piece 23 and the machine body 1, and the second connecting piece 25 fixedly connects the mounting piece 23 and the machine body 1. The third mounting hole 231 arranged on the mounting piece 23 cooperates with the second connecting piece 25, and the fourth mounting hole 11 arranged on the machine body 1 cooperates with the second connecting piece 25. The third mounting hole 231 and the fourth mounting hole 11 are correspondingly arranged, and the second connecting piece 25 passes through the third mounting hole 231 and the fourth mounting hole 11 to fixedly connect the mounting piece 23 and the machine body 1. The second connecting piece 25 is a screw, and the third mounting hole 231 and the fourth mounting hole 11 are internally threaded holes matched with external threads of the screw. The second connecting piece 25 comprises a second body 251 and a second end 252 connected with the second body 251, and the diameter of the second end 252 is larger than that of the second body 251. The second body 251 has external threads to be matched with the third mounting hole 231 and the fourth mounting hole 11. The mounting direction of the second connecting piece 25 is from the side where the walking wheel 22 is located to the side where the machine body 1 is located. When the second connecting piece 25 is mounted on the mounting piece 23 and the machine body 1, the second end 252 is arranged on the side where the mounting piece 23 is located. The mounting direction is convenient for user operation, and the user does not need to stretch into the machine body 1 to perform mounting or dismounting operation on the second connecting piece 25. When the mounting piece 23 needs to be replaced, the walking wheel 22 is first dismounted from the driving mechanism 21, then the driving mechanism 21 is dismounted from the mounting piece 23, and then the second connecting piece 25 is operated, so that the mounting piece 23 can be replaced. The operation is simple, and the replacement cost of the mounting piece 23 is low.

[0045] Obviously, the number of the second connecting piece 25 is multiple, the third mounting hole 231 and the fourth mounting hole 11 are correspondingly arranged with the second connecting piece 25, and the stability of the connection between the mounting piece 23 and the machine body 1 is realized by the multiple second connecting pieces 25.

[0046] It should be noted that the third mounting hole 231 can be arranged on the mounting piece 23 and extend along the thickness direction of the mounting piece 23. At this time, the mounting piece 23 is relatively thick, and the connection strength is increased. In order to reduce the operation difficulty and cost, the thickness of the mounting piece 23 can be relatively thin, then a standard nut is welded on the mounting piece 23, the third mounting hole 231 is formed on the nut, and a relief hole is formed on the mounting piece 23 and communicates with the third mounting hole 231. Similarly, when the thickness of the shell of the machine body 1 at the position where the mounting piece 23 is arranged is small, a relief hole can also be formed on the shell, and a nut is welded on the relief hole. The fourth mounting hole 11 can be provided, and the preparation is simple and the cost is low. When the third mounting hole 231 or the fourth mounting hole 11 is invalid after the mounting piece 23 is dismounted and mounted for multiple times, only the nut needs to be replaced, so that the replacement cost is reduced.

[0047] After the mounting member 23 is mounted on the machine body 1, one end of the driving mechanism 21 is mounted on the mounting member 23, and the other end of the driving mechanism 21 is connected with the walking wheel 22. When the driving mechanism 21 is dismounted from the machine body 1, the walking wheel 22 is dismounted from the driving mechanism 21 first, so that the existence of the walking wheel 22 does not interfere with the operation space of the dismounting of the driving mechanism 21, and the operation difficulty is increased. After the walking wheel 22 is dismounted, the driving mechanism 21 is exposed, and at this time, the first connecting member 24 is conveniently operated to separate the driving mechanism 21 from the mounting member 23, so that the driving mechanism 21 is dismounted from the machine body 1. When the driving device 2 is assembled, the first connecting member 24 is operated to mount the driving mechanism 21 on the mounting member 23, and then the walking wheel 22 is mounted on the driving mechanism 21.

[0048] In the embodiment, the first connecting member 24 passes through the driving mechanism 21 and the mounting member 23 in sequence to connect the driving mechanism 21 and the mounting member 23. The mounting directions of the first connecting member 24 and the second connecting member 25 are the same, the mounting direction of the first connecting member 24 is the direction from the side where the walking wheel 22 is located to the side where the machine body 1 is located, that is, the user can operate outside the machine body 1. In this way, after the walking wheel 22 is dismounted, the operation end of the first connecting member 24 is exposed, and the user can conveniently operate the mounting or dismounting of the first connecting member 24.

[0049] Specifically, the driving mechanism 21 is provided with a first mounting hole 211 matched with the first connecting piece 24, the mounting piece 23 is provided with a second mounting hole 232 matched with the first connecting piece 24, and the first mounting hole 211 and the second mounting hole 232 are arranged in position correspondence. The first connecting piece 24 is first threaded through the first mounting hole 211 of the driving mechanism 21 and then threaded into the second mounting hole 232 of the mounting piece 23, so as to realize the fixed connection of the driving mechanism 21 and the mounting piece 23. When it is needed to disassemble the driving mechanism 21 from the mounting piece 23, the first connecting piece 24 is first disengaged from the second mounting hole 232 of the mounting piece 23 and then disengaged from the first mounting hole 211 of the driving mechanism 21. The mounting or dismounting of the first connecting piece 24 can be realized by means of a tool, such as an electric screwdriver, an electric wrench, a screwdriver, a wrench, etc. The first connecting piece 24 is a screw, and the first mounting hole 211 and the second mounting hole 232 are internally threaded holes matched with the external threads of the screw. The first connecting piece 24 comprises a first body 241 and a first end portion 242 connected with the first body 241, and a tool is matched with the first end portion 242 to realize the dismounting or mounting of the first connecting piece 24. The diameter size of the first end portion 242 is greater than that of the first body 241, and the first body 241 has external threads to realize the threaded matching with the first mounting hole 211 and the second mounting hole 232. The diameter size of the first end portion 242 is greater than that of the first mounting hole 211 and the second mounting hole 232, and when the first connecting piece 24 is mounted to the driving mechanism 21 and the mounting piece 23, the first end portion 242 is located at the side of the driving mechanism 21 away from the mounting piece 23, so as to facilitate the user to operate the first connecting piece 24 by means of the tool. Obviously, the number of the first connecting piece 24 is multiple, the first mounting hole 211 and the second mounting hole 232 are arranged in correspondence with the first connecting piece 24, and the stability of the connection between the driving mechanism 21 and the mounting piece 23 is realized by means of the multiple first connecting pieces 24. It should be noted that when the sum of the lengths of the first mounting hole 211 and the second mounting hole 232 is less than the length of the second body 211 of the first connecting piece 24, a relief hole is formed on the machine body 1 to accommodate at least part of the second body 211, so as to increase the connection stability of the driving mechanism 21 and the mounting piece 23.

[0050] In other embodiments, the first connecting piece 24 can also be other structures, such as a clamping structure arranged between the driving mechanism 21 and the mounting piece 23.

[0051] The driving mechanism 21 comprises a first mounting portion 212 and a second mounting portion 213, the first mounting portion 212 and the mounting member 23 cooperate to connect the driving mechanism 21 on the machine body 1, and the second mounting portion 213 and the traveling wheel 22 cooperate to connect the driving mechanism 21 and the traveling wheel 22. Obviously, the first mounting portion 212 is arranged close to the machine body 1 relative to the second mounting portion 213, and the second mounting portion 213 is located outside the first mounting portion 212. The first mounting hole 211 is arranged on the first mounting portion 212, and the first mounting portion 212 and the second mounting portion 213 have an operation space to connect or separate the first connecting member from the side of the first mounting portion close to the second mounting portion. As mentioned above, when the first connecting member 24 is disassembled or assembled, the first connecting member 24 needs to be aligned with the first mounting hole 211 on the side of the first mounting portion 212 away from the mounting member 23, and a tool needs to be placed at the first end portion 242 of the first connecting member 24, therefore, an operation space is needed on the side of the first mounting portion 212 close to the second mounting portion 213. In order to avoid the second mounting portion 213 interfering with the operation of the first connecting member 24, in the embodiment, the distance between the first mounting portion 212 and the second mounting portion 213 is greater than 100 mm, and the second mounting portion 213 is arranged away from the first mounting portion 212, so that the first mounting portion 212 and the second mounting portion 213 have a larger space to place the tool and the first connecting member 24, which facilitates the user to use the tool to operate the first connecting member 24.

[0052] The traveling wheel 22 comprises a rim 221 and a tire 222, wherein the rim 221 is a rigid support structure of the inner ring of the traveling wheel 22, and the tire 222 is an elastic buffer structure of the periphery of the traveling wheel 22, the rim 221 and the tire 222 are a split structure, but it does not exclude the possibility that they are an integral structure, for example, an integral molded airless wheel can also be used.

[0053] The driving mechanism 21 comprises a motor 214 and a reduction box 215 connected with the motor 214, the motor 214 is arranged close to the machine body 1, and the reduction box 215 is arranged close to the traveling wheel 22 and connected with the traveling wheel 22. The motor 214 comprises a motor shell and a motor shaft (not shown), obviously, the motor 214 also comprises a necessary rotor (not shown) and a stator (not shown), the stator is connected with the motor shell, and the rotor is connected with the motor shaft, the specific structure of the motor 214 is prior art, which will not be described here.

[0054] The reduction gearbox 215 comprises an input shaft (not shown), a reduction gearbox shell and a planetary reduction mechanism (not shown). The input shaft is connected with and rotates synchronously with the motor shaft to transmit the power of the motor 214 to the reduction gearbox 215 through the input shaft. The planetary reduction mechanism is installed between the input shaft and the reduction gearbox shell. The power of the input shaft is transmitted to the reduction gearbox shell through the planetary reduction mechanism. The reduction gearbox shell is connected with the rim 221 as the power output end of the reduction gearbox 215. The reduction gearbox 215 realizes reduction transmission with a large transmission ratio in a short axial space. The reduction gearbox 215 is at least partially located in the rim 221 to reduce the overall axial size of the driving device 2 and the width of the mower 100, facilitating the installation of other structures. In the embodiment, the reduction gearbox 215 is installed in the rim 221 to maximize the axial size of the driving device 2.

[0055] The planetary reduction mechanism comprises a sun gear connected with and rotating synchronously with the input shaft, a planet gear rotatingly connected with the sun gear, and a ring gear rotatingly connected with the planet gear and fixedly connected with the reduction gearbox shell. The number of planet gears is three, and the three planet gears are equidistantly arranged around the sun gear in the circumferential direction. The planet gears are respectively engaged with the sun gear and the ring gear. The power is transmitted from the input shaft to the reduction gearbox shell through the sun gear, the planet gear and the ring gear in sequence. It can be understood that the present disclosure can adopt one-stage, two-stage or more-stage planetary gear reduction. In the case of a certain power of the motor 214, a larger torque can be output, and the mower 100 can adapt to most complex working conditions.

[0056] The ring gear and the reduction gearbox shell can be an integral structure, which can simplify the assembly process, reduce the cumulative assembly error of the whole machine, reduce the assembly cost, make the structure of the whole machine more compact, and have a longer service life. Obviously, the ring gear and the reduction gearbox shell can also be separately arranged and fixedly connected to reduce the preparation difficulty.

[0057] In the embodiment, the first mounting portion 212 is formed on the motor shell. Alternatively, the first mounting portion 212 and the motor shell can be integrally formed to increase the strength. The first mounting portion 212 can also be fixedly arranged on the motor shell, which is not limited herein. The second mounting portion 213 is formed on the reduction gearbox shell. Similarly, the second mounting portion 213 and the reduction gearbox shell can be integrally formed or connected by a fixed connection. In order to ensure that the first mounting portion 212 and the second mounting portion 213 have a large enough spacing, the first mounting portion 212 is arranged at the end of the motor 214 away from the reduction gearbox 215, and the second mounting portion 213 is arranged on the reduction gearbox 215. The first mounting portion 212 and the second mounting portion 213 are spaced apart by at least the length of the motor 214 to ensure the smooth operation of the user on the first mounting portion 213.

[0058] It should be noted that the radial dimension of the motor housing is greater than the radial dimension of the reduction box housing in the embodiment, the first mounting portion 212 protrudes out of the motor housing, the second mounting portion 213 protrudes out of the reduction box housing, in order to further reduce the interference of the existence of the second mounting portion 213 on the operation of the first connecting piece 24, the first mounting hole 211 and the second mounting portion 213 do not overlap along the axial direction perpendicular to the driving mechanism 21, along the radial direction of the driving mechanism 21, the height of the first mounting portion 212 is greater than the height of the second mounting portion 213. That is, the second mounting portion 213 is lower than the height at which the first mounting hole 211 is located, along the extension direction of the first mounting hole 211, there is no interference of the second mounting portion 213, ensuring the smoothness of the installation or disassembly of the first connecting piece 24.

[0059] The walking wheel 22 can be installed on the reduction box 215 through the third connecting piece 26. The rim 221 of the walking wheel 22 is provided with a plurality of fifth mounting holes 223 matched with the third connecting piece 26, and the second mounting portion 213 is provided with a plurality of sixth mounting holes 2131 matched with the third connecting piece 26, the fifth mounting holes 223 and the sixth mounting holes 2131 are arranged one by one, and the third connecting piece 23 passes through the fifth mounting holes 223 and the sixth mounting holes 2131 in sequence to fix the walking wheel 22 on the reduction box 215. The installation direction of the third connecting piece 26 is the same as the installation direction of the above-mentioned first connecting piece 24, which will not be repeated here. The third connecting piece 26 is also a screw, and the fifth mounting hole 223 and the sixth mounting hole 2131 are internally threaded holes.

[0060] When the driving mechanism 21 is maintained, the third connecting piece 26 is first separated from the fifth mounting hole 223 and the sixth mounting hole 2131, the walking wheel 22 is disassembled from the reduction box 215, then the first connecting piece 24 is separated from the second mounting hole 232 and the first mounting hole 211, and the driving mechanism 21 is disassembled from the mounting piece 23, so that the driving mechanism 21 can be maintained. The driving mechanism 21 is maintained, and the driving mechanism 21 is installed on the mounting piece 23, and then the walking wheel 22 is installed on the driving mechanism 21. The maintenance of the driving mechanism 21 does not need to disassemble the second connecting piece 25 between the mounting piece 23 and the fuselage 1, effectively avoids the invalidation of the fourth mounting hole 11 formed on the fuselage 1, because the disassembly frequency of the driving mechanism 21 increases, only the mounting piece 23 needs to be replaced, which increases the disassembly life of the driving mechanism 21 and reduces the replacement difficulty and cost.

[0061] It should be noted that the installation piece 23 is added between the driving mechanism 21 and the machine body 1, which not only increases the disassembly and assembly life of the driving mechanism 21, but also can be compatible with different driving mechanisms 21 installed on the same machine body 1. By changing the position of the second mounting hole 232 provided on the installation piece 23, different driving mechanisms 21 can be installed on the machine body 1. Different driving mechanisms 21 can be adapted without changing the structure of the machine body 1, thereby improving the versatility of the mower 100.

[0062] The mower 100 further comprises a cutting device (not shown) provided on the machine body 1, which comprises a cutting element provided at the bottom of the machine body 1 and a driving structure provided on the machine body 1. The driving structure can be a power structure such as a motor. The output shaft of the driving structure is connected to the cutting element to drive the cutting element to rotate around its own axis to perform cutting work. The specific structure of the cutting element is not limited, and the cutting element can only rotate to cut. The cutting element comprises a cutter head and a blade provided on the cutter head. During rotation of the cutting element, the end of the blade away from the cutter head rotates to form a circular profile, which is the cutting area of the cutting element. The blade can be designed to be fixed on the cutter head, or can be designed as a telescopic structure, for example, the blade extends out of the cutter head under centrifugal force during rotation, and the blade is automatically stored in the cutter head when not rotating, so as to protect the blade. The cutting element can also comprise at least two layers of blades provided on the cutter head.

[0063] In some embodiments, the cutting device is provided in at least two groups, and each group of cutting devices is distributed in a staggered manner on the machine body 1 to avoid a large space caused by a linear arrangement, thereby improving the structural compactness of the mower 100. In order to avoid the situation of grass leakage, the cutting areas of the two groups of cutting devices are connected or at least partially overlapped. The cutting device can be arranged between the front and rear wheels. It can be understood that the cutting device can not only be arranged between the front and rear wheels, but also can be arranged on the front side, rear side or side of the machine body 1.

[0064] In an embodiment, the mower 100 further comprises a control device (not shown), which is in signal connection with the above-mentioned driving device 2, cutting device and the like to control the working of the driving device 2 and the cutting device.

[0065] In order to realize the self-moving of the mower 100 for cutting work without user intervention and improve the user experience, the mower 100 further comprises a positioning device arranged on the machine body 1 to obtain the position coordinates of the mower 100, and the mower 100 realizes automatic navigation according to the position coordinates to move along the preset path. The positioning device comprises a positioner for receiving satellite signals and / or base station signals and outputting positioning data. The control device is arranged in the machine body 1 and is used to obtain the position data of the self-moving device according to the positioning data output by the positioning device (positioner). The positioning device can be offset or centrally arranged on the machine body 1. Alternatively, the positioning device can be detachably connected with the machine body 1. On the other hand, the positioning device can obtain the coordinate information of the position where it is located by absolute positioning or relative positioning, and correspondingly, the positioning device can comprise a visual sensor (such as a monocular camera, a multi-view camera, a depth camera, etc.), an image sensor, a satellite positioning sensor, etc., and correspondingly, the positioning device can obtain the coordinate information of the position where it is located by using one or more of the following positioning technologies: GPS technology, visual simultaneous localization and mapping (VSLAM) technology, real-time dynamic (RTK) positioning technology, etc.

[0066] Please refer to Figure 3 and Figure 4 , the structure of the mower 100 shown in another embodiment of the present application is basically the same as that shown in the above embodiment, and the difference is the specific structure of the mounting member 23 and the connection mode of the driving mechanism 21 with the mounting member 23 and the traveling wheel 22.

[0067] Specifically, the mounting member 23 is a hollow barrel structure, and each end of the mounting member 23 is provided with a flange 233. The third mounting hole 231 matched with the fourth mounting hole 11 on the machine body 1 is arranged on the flange 233 close to the machine body 1 of the mounting member 23, and the second mounting hole 232 matched with the first mounting hole 211 of the driving mechanism 21 is arranged on the flange 233 away from the machine body 1 of the mounting member 23. The distance between the two flanges 233 is greater than 100 mm, so as to facilitate the second connecting member 25 to be matched with the third mounting hole 231 from the gap between the two flanges 233, and facilitate the user to use tools to assemble the second connecting member 25 from the side away from the machine body 1 of the third mounting hole 231 into the third mounting hole 231 and the fourth mounting hole 11.

[0068] The first mounting portion 212 and the second mounting portion 213 are arranged on the reduction box 215, that is, the reduction box 215 is connected with the walking wheel 22 and the mounting member 23 respectively, and the motor 214 only needs to be connected with the reduction box 215. The motor 214 is arranged in the mounting member 23, and in this mounting mode, the motor shell is not subjected to force, the strength of the motor shell can not need to be additionally increased, and the motor shell can be made of aluminum material, thereby saving the manufacturing cost. The motor 214 needs to be cooled during operation, and therefore, the mounting member 23 is provided with a cooling hole 234, so as to facilitate the cooling of the motor 214. In the above embodiment, the motor shell is connected with the mounting member 23, and at this time, the strength of the motor shell needs to be increased, so as to ensure the degree of force bearing of the motor shell and increase the service life.

[0069] Obviously, the distance between the first mounting portion 212 and the second mounting portion 213 is less than 100 mm, in order to realize the cooperation and assembly of the first connecting member 24 from the first mounting hole 211 on the side away from the second mounting hole 232 and the first mounting hole 211, the first mounting hole 211 and the second mounting portion 213 do not overlap along the axial direction perpendicular to the driving mechanism 21, and along the radial direction of the driving mechanism 21, the height of the first mounting portion 212 is greater than the height of the second mounting portion 213. That is, the second mounting portion 213 is lower than the height at which the first mounting hole 211 is located, and along the extension direction of the first mounting hole 211, the second mounting portion 213 does not form interference, so as to ensure the smoothness of the installation or disassembly of the first connecting member 24.

[0070] When the driving mechanism 21 is maintained, the third connecting member 26 is first separated from the fifth mounting hole 223 and the sixth mounting hole 2131, the walking wheel 22 is disassembled from the reduction box 215, then the first connecting member 24 is separated from the second mounting hole 232 and the first mounting hole 211, and the driving mechanism 21 is disassembled from the mounting member 23, so that the driving mechanism 21 can be maintained. The driving mechanism 21 is maintained, the driving mechanism 21 is installed on the mounting member 23, and then the walking wheel 22 is installed on the driving mechanism 21. The maintenance of the driving mechanism 21 does not need to disassemble the second connecting member 25 between the mounting member 23 and the fuselage 1, effectively avoids the invalidation of the fourth mounting hole 11 formed on the fuselage 1, and only needs to replace the mounting member 23 due to the increase of the disassembly times of the driving mechanism 21, thereby increasing the maintenance and disassembly life of the driving mechanism 21 and reducing the replacement difficulty and cost.

[0071] In another embodiment, the first connecting piece 24 can also be assembled or disassembled from the side of the first mounting part 212 away from the second mounting part 213 and the first mounting hole 211. As described above, the distance between the two flanges 233 of the mounting part 23 is greater than 100 mm. When the distance between the two flanges 233 is large enough, the user can disassemble or assemble the first connecting piece 24 from the side of the first mounting hole 211 close to the machine body 1. Similarly, only the driving mechanism 21 needs to be disassembled from the mounting part 23 to repair the driving mechanism 21, without disassembling the mounting part 23 and the second connecting piece 25 on the machine body 1, thereby ensuring the service life of the machine body 1.

[0072] In summary, the driving mechanism for driving the walking wheel of the garden tool is mounted on the machine body through the mounting part. When the driving mechanism is disassembled for maintenance, only the first connecting piece connecting the driving mechanism and the mounting part needs to be disassembled, so that the driving mechanism can be disassembled from the machine body, without disassembling the connecting piece for mounting the mounting part on the machine body. This makes the connecting part of the machine body not easy to be damaged, and the increase in the disassembly frequency of the driving mechanism will only cause damage to the connecting part of the mounting part. At this time, only the mounting part needs to be replaced, thereby reducing the difficulty and cost of maintenance.
