[0010] In one embodiment, the first planet carrier and the second sun gear are integrally formed.
[0011] In one embodiment, the second reduction assembly further includes a connecting shaft, which is detachably connected to the first reduction assembly, and the connecting shaft is interference fit with the first sun gear.
[0012] In one embodiment, the first execution unit also includes a handle fixedly connected to the inner gear ring, and the handle has an unlocked state and a locked state; when the handle is in the locked state, the handle is blocked by the body, and the body restricts the rotation of the handle; when the handle is in the unlocked state, the handle is separated from the body, and the body releases the restriction on the rotation of the handle.
[0013] In one of the embodiments, the body structure has a limiting member, and when the handle is in the locked state, the handle is blocked and limited by the limiting member.
[0014] In one embodiment, the first execution component includes a leaf sweeping roller and a leaf sweeping brush connected to the leaf sweeping roller; one end of the leaf sweeping roller along its own axis is connected to the second reduction component, and the other end is movably connected to the machine body; and / or

[0042] Figure 1 A three-dimensional schematic diagram of a garden tool provided in one embodiment of the present application. Figure 2 for Figure 1 The three-dimensional schematic diagram of the garden tool installed with the first execution unit is shown. Figure 7 for Figure 3 The 3D schematic diagram of the first execution unit in the garden tool is shown. Figure 1 , Figure 2and Figure 7 As shown, a garden tool 10 provided in an embodiment of the present application includes a body 100, a plurality of running wheels 400, a driving mechanism 200 and an actuator, wherein the plurality of running wheels are arranged on both sides of the body; the driving mechanism 200 is arranged in the body 100, and includes a driving member 210 and a first reduction assembly 220 connected to the driving member 210; the actuator includes a first actuator unit 310 and a second actuator unit which are arranged selectively, and the second actuator unit is detachably connected to the first reduction assembly 220; the first actuator unit 310 includes a second reduction assembly 311 detachably connected to the first reduction assembly 220 and a first actuator assembly 312 connected to the second reduction assembly 311, and the second reduction assembly 311 is used to reduce the output power of the driving mechanism 200 and transmit it to the first actuator assembly 312.
[0043] The driving mechanism 200 provides power to the first executing unit 310 or the second executing unit, so that the first executing unit 310 or the second executing unit is in motion. For example, the first executing component 312 is a leaf sweeping component, and the second executing unit is a grass combing component. When the leaf sweeping function needs to be realized, the first executing unit 310 is installed on the machine body 100. Since the second reduction component 311 is installed on the first executing component 312, i.e., the leaf sweeping component, the output power of the driving mechanism 200 is first decelerated by the first reduction component 220, and then the output power of the driving mechanism 200 is decelerated for the second time by the second reduction component 311, so that the rotation speed of the leaf sweeping component meets the required lower working speed.
[0044] When the grass combing function needs to be realized, the first execution unit 310 is removed, and the second execution unit, i.e., the grass combing assembly, is installed on the machine body 100. The power of the driving mechanism 200 is transmitted to the grass combing assembly after only one deceleration through the first reduction assembly 220, so as to meet its higher working speed relative to the first execution unit 310, thereby realizing the grass combing function. When in use, the user can install the corresponding execution unit according to the actual use requirements to realize functions such as leaf sweeping, grass combing or loosening soil, so as to realize one machine for multiple uses, without the need to purchase leaf sweepers and grass combers separately, etc., thereby reducing costs while reducing occupied space and improving the user's use experience. By setting the walking wheel 400 that is rotatably connected to the machine body 100, it is convenient for the staff to push the garden tool 10 to clean different areas. Further, the garden tool also includes a handrail frame (not shown) connected to the machine body, and the handrail frame is provided to facilitate the staff to hold and push the garden tool.
[0045] like Figure 7As shown, in one embodiment, the first reduction assembly 220 includes a driving wheel 221, a driven wheel 222 and a transmission belt 223. The driving wheel 221 is connected to the driving member 210, and the driving wheel 221 is driven by the driving member 210 to rotate around its own axis. The driving wheel 221 and the driven wheel 222 are in transmission connection with the transmission belt 223, so that the transmission belt 223 can transmit the power of the driving wheel 221 to the driven wheel 222. The first reduction assembly 220 is used to reduce speed during the transmission process, so that the actuator rotates at a moderate speed. When replacing the first execution unit 310 or the second execution unit, even if it is disassembled and assembled multiple times, it will not affect the driving member 210, thereby extending the service life of the driving member 210.
[0046] When the first execution unit 310 is installed on the garden tool 10, the input shaft of the second reduction assembly 311 is coaxially connected with the driven wheel 222, so that the driven wheel 222 can transmit power to the second reduction assembly 311, and transmit it to the first execution assembly 312 through the second reduction assembly 311 to perform operations such as sweeping leaves. When the second execution unit is installed on the garden tool 10, the driven wheel 222 is coaxially connected with the second execution unit, and power is transmitted to the second execution unit through the driven wheel 222 to perform operations such as combing grass or loosening soil. By setting the first reduction assembly 220, low-speed high torque is output to improve the cleaning or combing effect. Specifically, the driving member 210 can be a motor, the driving wheel 221 and the driven wheel 222 can be rubber wheels, and the transmission belt 223 is a belt, and the rubber wheel and the belt are frictionally driven. In other embodiments, the driving wheel and the driven wheel can also be sprocket wheels, and the transmission belt can specifically be a chain that meshes with the sprocket wheels.
[0047] Figure 8 for Figure 7 The exploded schematic diagram of the second reduction assembly in the garden tool is shown. Figure 7 and Figure 8 As shown, in a specific embodiment, the second reduction assembly 311 includes a first sun gear 3111, a plurality of first planetary gears 3112, a first planet carrier 3113 and an inner gear ring 3114. The first sun gear 3111 is detachably connected to the first reduction assembly 220, and the first reduction assembly 220 transmits the rotational power to the first sun gear 3111, so that the first sun gear 3111 rotates around its own axis. The plurality of first planetary gears 3112 are arranged circumferentially on the first planet carrier 3113, that is, the plurality of first planetary gears 3112 are arranged on the outer ring of the first sun gear 3111, and mesh with the first sun gear 3111 for transmission, and the first planetary gear 3112 is meshed with the inner gear ring 3114 for transmission on the side away from the first sun gear 3111.
[0048] When the first sun gear 3111 drives the plurality of first planetary gears 3112 to rotate, since the inner gear ring 3114 is fixedly connected to the body 100, that is, the inner gear ring 3114 does not rotate, the first planetary gear 3112 moves along the circumferential direction of the inner gear ring, and the first planetary gear 3112 drives the first planet carrier 3113 to rotate around the axis while moving, thereby driving the first actuator 312 fixedly connected to the first planet carrier 3113 to operate, thereby realizing functions such as leaf sweeping. By controlling the gear ratio of the first sun gear 3111 and the inner gear ring 3114, the actual required transmission ratio is met, and the reduction transmission is realized to meet the low speed operation requirements of the first actuator 312. Since the first sun gear 3111 is detachably connected to the first reduction assembly 220, when other actuators need to be replaced, the first actuator 310 can be conveniently removed from the first reduction assembly 220 to install the second actuator to realize other functions.
[0049] like Figure 7 and Figure 8 As shown, in some embodiments, the second reduction assembly 311 further includes a connecting shaft 3118, which is detachably connected to the first reduction assembly 220, and the first sun gear 3111 is interference-fitted with the connecting shaft 3118. The interference-fit setting of the first sun gear 3111 and the connecting shaft 3118 ensures the reliability of the power transmission of the connecting shaft 3118 to the first sun gear 3111, and ensures the operating reliability of the first actuator 312.
[0050] See also Figure 7 and Figure 8 As shown, in one embodiment, the second reduction assembly 311 also includes a second sun gear 3115, a plurality of second planetary gears and a second planet carrier 3117. The second sun gear 3115 is fixedly connected to the first planet carrier 3113, so that the first planet carrier 3113 rotates and drives the second sun gear 3115. The plurality of second planetary gears are arranged circumferentially on the second planet carrier 3117 and arranged on the outer ring of the second sun gear 3115, and mesh with the second sun gear 3115 for transmission, so as to be driven to rotate by the second sun gear 3115. Since the inner gear ring 3114 meshing with the second planetary gear is fixed on the body 100, the second planetary gear moves along the circumferential direction of the inner gear ring 3114, drives the second planet carrier 3117 to rotate, and then drives the first actuator 312 fixedly connected to the second planet carrier 3117 to rotate. By setting a two-stage planetary gear transmission structure, not only can the output speed required by the first actuator 312 be met, but also the space occupied by the transmission structure can be reduced, so that the layout of the entire garden tool 10 is more compact and reasonable.
[0051] like Figure 7 and Figure 8As shown, in one embodiment, the first planet carrier 3113 and the second sun gear 3115 are integrally formed. That is to say, when the first planetary gears 3112 drive the first planet carrier 3113 to rotate, the second sun gear 3115 must be able to rotate synchronously. Through this arrangement, the reliability of the rotational power of the first planet carrier 3113 being transmitted to the second sun gear 3115 is guaranteed. On the other hand, since the first planet carrier 3113 and the second sun gear 3115 are integrally formed, the difficulty of assembly can be reduced and the installation efficiency can be improved. In other embodiments, the first planet carrier and the second sun gear can also be connected by a detachable connection method such as bolt connection and clamping to achieve the connection between the two.
[0052] See also Figure 7 and Figure 8 As shown, in some embodiments, one of the second planet carrier 3117 and the first actuator 312 is configured with a first clamping shaft 3121, and the other is configured with a first clamping hole 31171 for clamping with the first clamping shaft 3121. Specifically, the first clamping hole 31171 is provided on the second planet carrier 3117, and the first clamping shaft 3121 is provided on the first actuator 312. Through the clamping cooperation between the first clamping shaft 3121 and the first clamping hole 31171, the rotational power of the second planet carrier 3117 is transmitted to the rotating shaft of the first actuator 312, so that the first actuator 312 rotates. Among them, the first clamping hole 31171 can be a waist-shaped hole, and the shape of the first clamping shaft 3121 is adapted to the shape of the first clamping hole 31171 to ensure the reliability of power transmission. In other embodiments, the first clamping shaft can also be provided on the second planet carrier, and the first clamping hole can be provided on the first actuator.
[0053] Figure 3 for Figure 2 The three-dimensional schematic diagram of the garden tool with a hidden part is shown. Figure 3 As shown, in one embodiment, the first actuator 310 further includes a handle 313 fixedly connected to the inner gear ring 3114, and the handle 313 has an unlocked state and a locked state. When the handle 313 is in the locked state, the handle 313 is blocked by the body 100, and the body 100 limits the rotation of the handle 313. Since the handle 313 is connected to the inner gear ring 3114, in this state, the handle 313 is blocked from rotating by the body 100, thereby ensuring that the inner gear ring 3114 is relatively fixed, thereby ensuring the reliability of the first sun gear 3111 driving the first planetary carrier 3113 to rotate through the first planetary gear 3112, and ensuring the reliability of the second sun gear 3115 driving the second planetary carrier 3117 to rotate through the second planetary gear, thereby ensuring the rotation reliability of the first actuator 312.
[0054] When the handle 313 is in the unlocked state, the handle 313 is separated from the body 100, and the body 100 releases the rotation restriction on the handle 313. In this state, the handle 313 can be conveniently grasped to remove the first actuator unit 310 from the body 100. In addition, after the first actuator unit 310 is removed, the handle 313 can be directly grasped to take the first actuator assembly 312. Specifically, the handle 313 includes a connecting section and a gripping section connected to the end of the connecting section, and the connecting section and the gripping section make the handle 313 present an L shape, and the operator can grasp the gripping section to take the first actuator assembly 312.
[0055] like Figures 3 to 6 As shown, in a specific embodiment, the body 100 is configured with a limiting member 314, and when the handle 313 is in a locked state, the handle 313 is blocked and limited by the limiting member 314. By arranging the limiting member 314 on the body 100 to block the handle 313, the rotation of the handle 313 is limited, thereby ensuring the reliability of fixing the inner gear ring 3114 in the second reduction assembly 311, thereby ensuring the reliability of the second planet carrier 3117 driving the first actuator 312 to operate.
[0056] Specifically, Figures 3 to 6 As shown, the limiting member 314 can be a leaf spring, which is approximately V-shaped. When the handle 313 is in the unlocked state, the handle 313 rotates around the first actuator 312 and squeezes the tip 3141 of the V-shaped leaf spring, and the V-shaped leaf spring is deformed, so that the handle 313 bypasses the tip 3141 of the V-shaped leaf spring until the handle 313 rotates to abut against the first inclined surface 3142 of the V-shaped leaf spring, at which time the deformation of the V-shaped leaf spring is restored. The handle 313 is blocked by the tip 3141 of the V-shaped leaf spring, so that the handle 313 is in the locked state. At the same time, a limiting groove 140 is provided on the body 100, which cooperates with the V-shaped leaf spring to limit the handle 313 in the locked state.
[0057] In the front-to-back direction of the machine body 100 (the front-to-back direction is Figure 3 and Figure 6 For example, refer to Fig.10 , Fig.11 and Figure 6, the side of the handle 313 away from the first inclined surface 3142, that is, away from the front side 3131, is the rear side 3132; the V-shaped leaf spring is bolted to the side wall 141 on one side of the limiting groove 140. The distance between the tip 3141 of the V-shaped leaf spring and the side wall 141 is slightly greater than the maximum distance between the rear side 3132 and the side wall 141, so that when the handle 313 bypasses the V-shaped leaf spring and is located deep in the limiting groove 140, without applying external force, the handle 313 cannot bypass the tip 3141 and rotate counterclockwise to rotate out of the limiting groove 140, that is, the handle 313 is fixed relative to the body 100 and will not rotate around the installation shaft 31221, thereby ensuring that the inner gear ring 3114 connected to the handle 313 is relatively fixed, that is, the inner gear ring 3114 will not rotate around the installation shaft 31221, thereby ensuring the rotation reliability of the first actuator 312. The cooperation between the limiting groove 140 and the V-shaped leaf spring limits the handle 313 from rotating counterclockwise, thereby ensuring the reliability of the second reduction assembly 311 driving the first actuator assembly 312 to rotate.
[0058] Fig. 9 for Figure 7 The three-dimensional schematic diagram of the first execution component in the garden tool shown in FIG. Figure 7 and Fig. 9 As shown, in a specific embodiment, the first actuator 312 includes a leaf sweeping roller 3122 and a leaf sweeping brush 3123 connected to the leaf sweeping roller 3122; one end of the leaf sweeping roller 3122 along its own axial direction is connected to the second reduction assembly 311, and the other end is movably connected to the body 100. In this way, the driving mechanism 200 transmits power to the leaf sweeping roller 3122 through the second reduction assembly 311 after deceleration by the first reduction assembly 220, driving the leaf sweeping brush 3123 on the leaf sweeping roller 3122 to rotate, thereby picking up fallen leaves on the ground or lawn, and realizing the leaf sweeping function.

Fig.10 and Fig.11 As shown, in some embodiments, the leaf sweeping roller 3122 includes a mounting shaft 31221 and a blocking shaft 31222 sleeved on one end of the mounting shaft 31221; the leaf sweeping brush 3123 is sleeved on the mounting shaft 31221, and one end of the leaf sweeping brush 3123 abuts against the blocking shaft 31222; the leaf sweeping brush 3123 includes a plurality of blades connected to the leaf sweeping brush 3123; and the plurality of blades are arranged at intervals along the circumference of the leaf sweeping roller 3122.
[0060] Specifically, when one of the blades rotates to be parallel to the ground, the other blade can contact the ground. By providing a plurality of blades distributed along the circumferential direction, the probability of the leaf sweeping brush 3123 contacting fallen leaves during rotation is greatly increased, thereby improving the cleaning efficiency. Since the leaf sweeping brush 3123 is sleeved on the mounting shaft 31221 of the leaf sweeping roller 3122, when the leaf sweeping brush 3123 is worn and needs to be replaced, the blocking shaft 31222 sleeved on the end of the mounting shaft 31221 is removed, so that the blocking shaft 31222 is released from limiting the leaf sweeping brush 3123. Therefore, the old leaf sweeping brush 3123 can be pulled out from the mounting shaft 31221 along the axial direction, and then the new leaf sweeping brush 3123 can be re-sleeved on the mounting shaft 31221, and the leaf sweeping brush 3123 can be abutted and limited by the blocking shaft 31222 to ensure the connection effect between the leaf sweeping brush 3123 and the mounting shaft 31221, thereby ensuring the operational reliability of the leaf sweeping brush 3123. In this process, it is only necessary to pull out the leaf sweeping brush 3123 along the axial direction of the leaf sweeping roller 3122, and the replacement operation is simpler and more convenient. In addition, during the replacement process, it is not necessary to replace the entire leaf sweeping roller 3122 and the leaf sweeping brush 3123, thereby reducing the replacement cost.
[0061] like Fig.10 and Fig.11 As shown, in some embodiments, one of the blocking shaft 31222 and the installation shaft 31221 is configured with a plug hole, and the other is connected to the hole wall of the plug hole. Specifically, the plug hole is configured on the installation shaft 31221, that is, the end size of the installation shaft 31221 is larger than the size of the blocking shaft 31222, so that the blocking shaft 31222 can be sleeved on the inner wall of the installation shaft 31221. Through the plug-in cooperation of the two, the blocking shaft 31222 can limit the leaf sweeping brush 3123, and ensure the connection effect between the leaf sweeping brush 3123 and the installation shaft 31221. In other embodiments, the plug hole can also be provided on the blocking shaft, that is, the size of the blocking shaft is larger than the end size of the installation shaft, so that the installation shaft can be sleeved on the inner wall of the blocking shaft.
[0062] like Fig.10 and Fig.11 As shown, in a specific embodiment, the plug hole is set on the installation shaft 31221, and the blocking shaft 31222 is interference-fitted with the plug hole. Through this arrangement, the tightness of the connection between the blocking shaft 31222 and the installation shaft 31221 is ensured, thereby ensuring the reliability of the connection between the leaf sweeping roller 3122 and the leaf sweeping brush 3123, ensuring the reliability of the leaf sweeping roller 3122 driving the leaf sweeping brush 3123 to operate, and improving the reliability of the leaf sweeping mechanism's cleaning function.
[0063] like Fig.10 and Fig.11As shown, in another embodiment, the plug-in hole is provided on the mounting shaft 31221; the blocking shaft 31222 includes a blocking column and a sealing portion sleeved on the blocking column, and the sealing portion is interference fit with the plug-in hole. By sleeved the sealing portion on the blocking column and having an interference fit with the plug-in hole of the mounting shaft 31221, the tightness of the connection between the mounting shaft 31221 and the blocking shaft 31222 is improved. As the number of times the blocking shaft 31222 is assembled and disassembled increases, the sealing portion will be worn due to the interference fit between the sealing portion and the plug-in hole. When the sealing portion is worn, it is sufficient to replace the sealing portion, thereby ensuring the reliability of the connection while reducing the replacement cost. Specifically, the sealing portion can be a sealing ring.
[0064] In an optional embodiment, one of the blocking shaft and the leaf sweeping brush is configured with a clamping block, and the other is configured with a clamping groove for clamping with the clamping block. When the leaf sweeping brush is installed on the leaf sweeping roller, the reliability of synchronous rotation of the leaf sweeping roller and the leaf sweeping brush is ensured by the concave-convex cooperation of the clamping block and the clamping groove, and the possibility that the leaf sweeping roller rotates alone while the leaf sweeping brush does not rotate is reduced. The clamping block is provided on the leaf sweeping brush, and the clamping groove is provided on the blocking shaft.
[0065] In one embodiment, the clamping grooves and the clamping blocks are both multiple, and the multiple clamping grooves are evenly spaced along the circumference of the installation axis; each clamping groove is respectively clamped with a corresponding clamping block. By providing multiple clamping grooves and clamping blocks, the connection reliability between the leaf sweeping roller and the leaf sweeping brush is improved. At the same time, it is precisely because of the provision of multiple clamping grooves and clamping blocks that it is more conducive to aligning the clamping block and the clamping groove compared to providing a single clamping groove, thereby reducing the difficulty of installation.
[0066] like Fig. 9 As shown, in one embodiment, the leaf sweeping brush 3123 includes multiple groups, and the multiple groups of leaf sweeping brushes 3123 are arranged along the axial direction of the installation shaft 31221. By setting multiple groups of leaf sweeping brushes 3123, the cleaning area of the leaf sweeping brush 3123 is increased, and the cleaning efficiency is improved. At the same time, since the multiple groups of leaf sweeping brushes 3123 adopt a split design, compared with installing a larger-sized leaf sweeping brush 3123, the wear area of the leaf sweeping brush 3123 can be replaced in a targeted manner without replacing the entire leaf sweeping brush group, thereby reducing maintenance costs. Among them, along the axial direction of the installation shaft 31221, the blades of adjacent leaf sweeping brushes 3123 are arranged at an angle. In other words, along the axial direction of the installation shaft 31221, adjacent blades are staggered from each other. In this way, when one group of leaf sweeping brushes 3123 rotates to be parallel to the ground, the blades of the other group of leaf sweeping brushes 3123 can contact the ground, so that the probability of the leaf sweeping brushes 3123 contacting the ground is increased, achieving real-time leaf sweeping and improving cleaning efficiency.
[0067] Fig.12 for Figure 3 The garden tools shown are a three-dimensional schematic diagram from another perspective. Fig.13 for Fig.12The three-dimensional schematic diagram of the mounting base in the garden tool shown in FIG. Fig.12 and Fig.13 As shown, in one embodiment, a mounting seat 130 is provided on the machine body 100, and one end of the sweeping roller 3122 away from the second deceleration assembly 311 is mounted on the mounting seat 130 through a bearing seat. Further, a support groove 1321 is provided on the mounting seat 130, and the bearing seat is clamped in the support groove 1321.
[0068] like Fig.12 and Fig.13 As shown, in another embodiment, the mounting seat 130 includes a support portion 132 and a rotating portion 131 movably connected to the support portion 132, and a support groove 1321 is configured on the support portion 132. Before installation, the rotating portion 131 is opened relative to the support portion 132 so that the leaf sweeping roller 3122 is clamped in the support groove 1321 through the bearing seat. After the clamping is completed, the rotating portion 131 is closed and locked relative to the support portion 132, and the bearing seat is blocked from being separated from the support groove 1321 by the rotating portion 131, thereby completing the assembly of the bearing seat of the leaf sweeping roller 3122 and the mounting seat 130 of the machine body 100. The cooperation between the rotating portion 131 and the support portion 132 facilitates the installation and removal of the leaf sweeping roller 3122. Specifically, the mounting seat 130 includes a second rotating shaft 134 , one end of the second rotating shaft 134 is passed through the supporting portion 132 , and the other end is passed through the rotating portion 131 . The rotating portion 131 can rotate relative to the supporting portion 132 around the second rotating shaft 134 .
[0069] like Fig.12 and Fig.13 As shown, in another embodiment, the mounting seat 130 further includes a locking portion 133. The locking portion 133 has a locking position and an unlocking position. When the locking portion 133 moves to the locking position, the locking portion 133 is connected to the rotating portion 131 to limit the rotation of the rotating portion 131, thereby ensuring the reliability of the leaf sweeping roller 3122 being installed on the machine body 100 through the bearing seat. When the locking portion 133 moves to the unlocking position, the locking portion 133 is disconnected from the rotating portion 131, and the rotation restriction on the rotating portion 131 is released, so that the rotating portion 131 can be opened or closed relative to the supporting portion 132, thereby enabling the first actuator 312 to be removed from the machine body 100. By toggling the locking portion 133 to move, it is switched between the locking position and the unlocking position.
[0070] like Figure 1 and Figure 2 As shown, in an optional embodiment, the garden tool 10 further includes a first housing 500 movably connected to the rear end of the body 100; the rear end of the body 100 is provided with a collecting port 510; the first housing 500 has a first state and a second state, such as Figure 1As shown, when the first shell 500 is in the first state, the first shell 500 exposes the collecting port 510, so that the collecting member (not shown) is fixed to the collecting port 510, and the fallen leaves can be thrown into the collecting member through the collecting port 510. When the first shell 500 is in the second state, the first shell 500 closes the collecting port 510. During use, the driving member 210 is started, and the garden tool 10 is pushed forward while holding the handrail. The driving member 210 drives the first execution unit 310 to rotate to realize the leaf sweeping function. While the leaf sweeping brush 3123 rotates, the fallen leaves are thrown into the collecting member, thereby collecting the fallen leaves and the like.
[0071] like Figures 1 to 3 As shown, in an optional embodiment, the machine body 100 is provided with a first rotating shaft 110, and a portion of the first housing 500 is rotatably connected to the machine body 100 via the first rotating shaft 110. When normal operation is required, the operator acts on the portion of the first housing 500 to open it relative to the machine body 100, as shown in FIG. Figure 1 As shown, the collecting port 510 is exposed so that the collecting member can be installed at the collecting port 510 .
[0072] like Figures 1 to 3 As shown, in another embodiment, a reset element 120 is further connected between the first shell 500 and the body 100; the reset element 120 is sleeved on the first rotating shaft 110, and the reset element 120 is used to drive the part of the first shell 500 to reset when the external force applied to the part of the first shell 500 is removed. That is to say, when the operator applies force to the part of the first shell 500 to open it, the reset element 120 is deformed. When the external force is removed, the part of the first shell 500 is closed relative to the body 100 under the elastic force of the reset element 120. By providing the reset element 120, the part of the first shell 500 can automatically return to the normal position without the operator manually resetting it, which is more convenient to use.
[0073] In some embodiments, the second execution unit may be a grass combing assembly, which is detachably connected to the first reduction assembly 220. The grass combing assembly includes a grass combing shaft connected to the first reduction assembly 220 and a grass combing blade connected to the grass combing shaft. The power of the driving member 210 is transmitted to the grass combing shaft through the first reduction assembly 220, so that the grass combing blade rotates, thereby performing a grass combing operation. The grass combing shaft and the output shaft of the first reduction assembly 220 may be connected by a coupling or a fastener such as a bolt.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
