These terms are only used to distinguish one described object from another. For example, a first path can be called a second path, and similarly, a second path can also be called a first path without departing from the scope of the present application.

[0045] The garden tool disclosed in the present application takes a hand-push mower as an example, of course, the garden tool is not limited to this, but also can be a rake or other garden tool which needs to adjust the distance between the machine body and the working surface. The function of adjusting the distance between the machine body and the working surface is to adjust the height of the cutter assembled on the machine body relative to the working surface. The working surface is the ground on which the garden tool walks.

[0046] AsFigures 1-3 As shown, the garden tool provided by the embodiment of the application comprises a machine body 10, a wheel 20 connected with the machine body 10 through an axle 30, and an adjusting assembly 40 for adjusting the distance between the machine body 10 and a working surface, the machine body 10 is supported on the working surface through the wheel 20, the axle 30 is rotatably connected with the machine body 10; the adjusting assembly 40 adjusts the distance between the machine body 10 and the working surface by driving the axle 30 to rotate; the adjusting assembly 40 comprises a connecting piece 1 and an operating piece 2, the connecting piece 1 is fixedly connected with the axle 30, the operating piece 2 moves relative to the connecting piece 1 when an operating force on a first path S1 is applied to the operating piece 2, so as to switch between a locked state and an unlocked state, the operating piece 2 is engaged with the machine body 10 in the locked state, so as to limit the rotation of the axle 30, and the operating piece 2 is disengaged from the machine body 10 in the unlocked state, so as to allow the rotation of the axle 30; in the unlocked state, the operating piece 2 drives the connecting piece 1 to move when an operating force on a second path S2 is applied to the operating piece 2, and drives the axle 30 to rotate through the connecting piece 1.

[0047] The garden tool provided by the embodiment of the application only needs to operate the operating piece 2 to easily adjust the height of the garden tool, so that the height adjustment process is simple and fast, and the convenience of height adjustment of the garden tool is greatly improved.

[0048] The first path S1 is a direction close to or away from the machine body 10, and the second path S2 can be a direction of rotation of the wheel 20, or the direction of the second path S2 is the same as the direction of rotation of the wheel 20. It should be noted that the operating force of the first path S1 direction applied by the operator can be a horizontal force perpendicular to the forward direction of the machine body 10, or a force in the same direction as the movement path of the end of the operating piece 2, that is, the first path S1 can be a straight path or a curved path, which depends on the connection mode of the operating piece 2 and the connecting piece 1, but the purpose is to make the operating piece 2 close to or away from the machine body 10 to realize locking or unlocking. Figure 1 、 2 The first path S1 is a direction close to or away from the machine body 10, and the second path S2 can be a direction of rotation of the wheel 20, or the direction of the second path S2 is the same as the direction of rotation of the wheel 20. It should be noted that the operating force of the first path S1 direction applied by the operator can be a horizontal force perpendicular to the forward direction of the machine body 10, or a force in the same direction as the movement path of the end of the operating piece 2, that is, the first path S1 can be a straight path or a curved path, which depends on the connection mode of the operating piece 2 and the connecting piece 1, but the purpose is to make the operating piece 2 close to or away from the machine body 10 to realize locking or unlocking.

[0049] Further, the adjusting assembly 40 further comprises a resilient piece 3, in the locked state, the resilient piece 3 biases the operating piece 2 towards the machine body 10, in the unlocked state, the operating force of the operating piece 2 on the first path S1 overcomes the biasing force of the resilient piece 3, and the operating piece 2 abuts against the connecting piece 1. The biasing force is a restoring force generated by the resilient piece 3 due to deformation, for example, compression or stretching. The resilient piece 3 biases the operating piece 2 towards the machine body 10, that is, through the biasing force of the resilient piece 3, the operating piece 2 is forced to be pushed to a fixed position close to or in contact with the machine body 10.

[0050] In some embodiments, the first path S1 is a straight path (not shown in the figures). The operating member 2 is connected to the connecting member 1 in a straight movable manner. In the locked state, the operating member 2 is biased by the elastic force of the elastic member 3 towards the body 10 as a whole, so as to be engaged with the body 10 to achieve locking. When the operating member 2 is applied with an operating force on the first path S1, i.e. the operating member 2 is applied with an operating force on the straight path away from the body 10, the operating member 2 moves in a straight line towards the direction away from the body 10 to overcome the biasing force of the elastic member 3, and abuts against the connecting member 1 to achieve unlocking.

[0051] In some embodiments, as shown in Figures 2-6 , the first path S1 is a curved path. The operating member 2 is rotatably connected to the connecting member 1. In the locked state, one end of the operating member 2 is biased by the elastic force of the elastic member 3 towards the body 10, and is engaged with the body 10 to achieve locking. When the one end of the operating member 2 is applied with an operating force on the first path S1, i.e. the operating member 2 is applied with an operating force on the curved path away from the body 10, the one end of the operating member 2 rotates towards the direction away from the body 10, and the other end of the operating member 2 rotates towards the direction close to the body 10 to overcome the biasing force of the elastic member 3, and abuts against the connecting member 1 to achieve unlocking, as shown in Figure 6 , the other end of the operating member 2 abuts against the side of the connecting member 1 away from the body 10.

[0052] Further, as shown in Figure 3 , the connecting member 1 comprises an opening part 11, the opening part 11 comprises a bottom wall 111, a first side wall 112 and a second side wall 113, the first side wall 112, the bottom wall 111 and the second side wall 113 define an opening of the opening part 11; the operating member 2 comprises a rotating connecting part 21, the rotating connecting part 21 is at least partially accommodated in the opening, and is rotatably connected to the connecting member 1 through the first side wall 112 and the second side wall 113. In the unlocked state, the distance between the rotating connecting part 21 and the bottom wall 111 reaches the maximum or the minimum. Specifically, in the present application, the distance between the rotating connecting part 21 and the bottom wall 111 is described as follows: the distance between the side of the bottom surface of the rotating connecting part 21 away from the body 10 and the bottom wall 111.

[0053] In some embodiments, as shown in Figure 4In some embodiments, the locking rib 221 is arranged above the rotating shaft 4, and in the unlocked state, the distance between the bottom surface of the rotating connecting part 21 and the bottom wall 111 on the side A away from the body 10 reaches a minimum value. In other embodiments, the locking rib 221 is arranged below the rotating shaft 4, and in the unlocked state, the distance between the bottom surface of the rotating connecting part 21 and the bottom wall 111 on the side away from the body 10 reaches a maximum value. That is, when the locking rib 221 is arranged on different sides of the rotating shaft 4, the distance between the rotating connecting part 21 and the bottom wall 111 reaches a maximum or minimum in the unlocked state. That is, when the locking rib 221 is arranged on one side of the rotating shaft 4, the distance between the rotating connecting part 21 and the bottom wall 111 reaches a maximum in the unlocked state; when the locking rib 221 is arranged on the other side of the rotating shaft 4, the distance between the rotating connecting part 21 and the bottom wall 111 reaches a minimum in the unlocked state. Changes in other structures to form the extreme changes in the distance between the rotating connecting part 21 and the bottom wall 111 will not be described here.

[0054] Of course, the distance between the side B of the bottom surface of the rotating connecting part 21 close to the body 10 and the bottom wall 111 can also be set as the distance between the rotating connecting part 21 and the bottom wall 111. Then, when the locking rib 221 is arranged above the rotating shaft 4, as shown in FIG. 2B, the distance between the rotating connecting part 21 and the bottom wall 111 reaches a maximum value in the unlocked state. When the locking rib 221 is arranged below the rotating shaft 4 close to the connecting piece 1, the distance between the rotating connecting part 21 and the bottom wall 111 reaches a minimum value. Figure 4

[0055] Further, as shown in FIG. 2C, Figure 3 5 In some embodiments, the connecting piece 1 further comprises a threaded part 12 and a communication part 13, the threaded part 12 and the communication part 13 are respectively located on both sides of the opening part 11 and are arranged in the direction of the first axis X, the threaded part 12 is provided with a threaded hole 121, and the communication part 13 is provided with a connecting hole 131; the rotating connecting part 21, the first side wall 112, and the second side wall 113 are all provided with through holes 114; the adjusting assembly 40 further comprises a rotating shaft 4, the rotating shaft 4 comprises a light rod part 41 and a screw rod part 42 located at one end of the light rod part 41, and the rotating shaft 4 sequentially passes through the threaded hole 121 of the threaded part 12, the through hole 114 of the first side wall 112, the through hole 114 of the rotating connecting part 21, the through hole 114 of the second side wall 113, and the connecting hole 131 of the communication part 13 in the direction of the first axis X, wherein the screw rod part 42 cooperates with the threaded hole 121, and the light rod part 41 cooperates with the through holes 114 and the connecting hole 131, so that the rotating connecting part 21 and the connecting piece 1 are rotationally connected.

[0056] ​​In the present application, the operating member 2 and the connecting member 1 are connected by means of the rotating shaft 4 which passes through the screw hole 121, the through hole 114 and the connecting hole 131 in sequence. When the connecting member 1 is fixed, the operating member 2 can rotate around the central axis of the rotating shaft 4. The first side wall 112 and the second side wall 113 of the opening part 11 are actually the side edges of the threaded part 12 and the connecting part 13. The through hole 114 in the first side wall 112 and the second side wall 113 is in communication with the screw hole 121 of the threaded part 12 and the connecting hole 131 of the connecting part 13, or in other words, the through hole 114 is part of the screw hole 121 or the connecting hole 131. One end of the rotating shaft 4 is provided with a thread which is screwed into the screw hole 121 in the threaded part 12, so that the connection between the operating member 2 and the connecting member 1 is more secure, and there is no need to additionally provide a fixing structure at both ends of the rotating shaft 4 to prevent the rotating shaft 4 from falling off.

[0057] Further, the elastic members 3 are provided in two and are configured as springs. In the extension direction of the rotating shaft 4, the two elastic members 3 are located on both sides of the rotating connection part 21. Figure 3 In the present application, two first positioning grooves 143 are provided at positions on both sides of the connecting member 1 below the opening. Figure 5 In the present application, two second positioning grooves 231 are provided at positions of the operating member 2 below the rotating connection part 21. The two ends of the two elastic members 3 are respectively arranged in the first positioning grooves 143 and the second positioning grooves 231, so that the elastic members 3 are more stable and are not easy to fall off. In the second positioning grooves 231, positioning protrusions 232 are further arranged, so that one end of the elastic member 3 is arranged between the inner wall of the second positioning groove 231 and the positioning protrusion 232, which better plays a role of positioning and prevents the elastic member 3 from deviating.

[0058] The two elastic members 3 are arranged on both sides of the connecting position of the connecting member 1 and the operating member 2. When the operating member 2 is subjected to an operating force, the operating member 2 has strong stability when rotating relative to the connecting member 1 due to the action of the two elastic members 3 on both sides.

[0059] In some embodiments, the operating member 2 further comprises an operating part 22 for a user to hold and an abutting part 23 connected with the rotating connection part 21. The abutting part 23 and the operating part 22 are located on both sides of the rotating connection part 21, and the elastic member 3 is connected between the abutting part 23 and the connecting member 1. Figure 5 In the present application, the operating part 22 is located above the rotating connection part 21. The end of the operating part 22 away from the rotating connection part 21 is usually used for the operator to hold, so as to exert an operating force on the first path S1 or the second path S2. The abutting part 23 is located below the rotating connection part 21 and is used for abutting the elastic member 3. The aforementioned second positioning groove 231 is arranged in the abutting part 23.

[0060] The operating part 22 is provided with a clamping rib 221, and the machine body 10 is provided with a plurality of gear grooves 101. Figure 2In the embodiment, the adjusting assembly 40 is arranged between the wheel 20 and the machine body 10, and a plurality of gear grooves 101 are arranged close to the wheel 20, and preferably, the plurality of gear grooves 101 are arranged in a circumferential direction with the center axis of the wheel 20 as the center.

[0061] When the operator holds the operation part 22 to exert an operation force on the operation piece 2 in a direction away from the machine body 10, the one end of the operation part 22 is away from the machine body 10, the clamping ribs 221 are separated from the gear grooves 101, the abutting part 23 compresses the elastic piece 3 and abuts against the connecting piece 1, the operation piece 2 is in the unlocked state, and the operator can hold the operation part 22 and exert an operation force on the second path S2 to drive the connecting piece 1 to move the clamping ribs 221 to the opening position of the desired gear groove 101. At this time, when the operator removes the operation force, the elastic piece 3 pushes the abutting part 23 away from the machine body 10 under the action of the elastic restoring force, so that the one end of the operation part 22 moves toward the machine body 10 to clamp the clamping ribs 221 and the desired gear groove 101, enters the locked state, and ends the height adjustment.

[0062] Preferably, in the unlocked state, the minimum distance between the edge A away from the machine body 10 in the bottom surface of the rotating connecting part 21 and the bottom wall 111 is 0, that is, in the unlocked state, the side of the rotating connecting part 21 away from the machine body 10 abuts against the bottom wall 111, so that when the operator exerts an operation force away from the machine body 10, once the rotating connecting part 21 abuts against the bottom wall 111, the operator can clearly perceive that the operation piece 2 has been unlocked, without the need to exert a greater force, thereby improving the stability of the unlocking process and the intuitiveness of the operation, enabling the operator to accurately judge the unlocking state and avoiding unnecessary force.

[0063] Further, the distance between the rotating shaft 4 and the elastic piece 3 is less than the distance between the rotating shaft 4 and the center position P of the operation part 22, as shown in Figure 5 In the embodiment, the dashed line at the position of the through hole 114 of the rotating connecting part 21 is the center axis of the rotating shaft 4, and the force arm L1 of the operation force exerted by the operator is greater than the force arm L2 of the spring when compressed, so that the operator can exert less force in the operation process.

[0064] In some embodiments of the present application, the connecting piece 1 further comprises a fixed connecting part 14, the fixed connecting part 14 extends at least partially along the direction of the second axis, the wheel shaft 30 is fixedly connected with the fixed connecting part 14, and the second axis is substantially parallel to the first axis X. It should be noted that the extension direction of the fixed connecting part 14 is substantially parallel to the first axis X, which means that the length direction of the fixed connecting part 14 is parallel to the first axis X or the included angle is less than a preset value, which are all regarded as parallel, and the preset value can be 5°, for example. The fixed connecting part 14 is fixedly connected with the wheel shaft 30, and the rotation of the fixed connecting part 14 can drive the wheel shaft 30 to rotate, so as to adjust the distance between the machine body 10 and the working surface.

[0065] Further, the wheel shaft 30 comprises a support shaft 301, a mounting shaft 302, and a connecting shaft 303 connected between the support shaft 301 and the mounting shaft 302, the support shaft 301 is rotationally connected with the body 10, the wheel 20 is rotationally connected with the mounting shaft 302, the axis of the support shaft 301 and the axis of the mounting shaft 302 are parallel; the fixed connecting part 14 is provided with a fixed groove 141 and a clearance hole 142 connected with the fixed groove 141, the mounting shaft 302 passes through the clearance hole 142, and the connecting shaft 303 is arranged in the fixed groove 141.

[0066] As shown in Figure 6 , 7 , the fixed connecting part 14 partially extends towards the body 10, forming an L-shaped fixed groove 141, after the mounting shaft 302 passes through the clearance hole 142, the connecting shaft 303 and one end of the support shaft 301 are arranged in the fixed groove 141. When in the unlocked state, the operator holds the operating part 22 and rotates in the direction of rotation of the wheel 20, driving the connecting piece 1 to rotate, since the distance between the mounting shaft 302 connected with the wheel 20 and the working surface does not change, when the wheel shaft 30 is driven to rotate by the connecting piece 1, the wheel shaft 30 will rotate with the axis of the mounting shaft 302 as the center line, the height difference between the support shaft 301 and the mounting shaft 302 changes, thereby adjusting the distance between the body 10 and the working surface.

[0067] In some embodiments of the present application, the adjusting assembly 40 comprises a plurality of gears from low gear to high gear, the gears are composed of the aforementioned a plurality of gear grooves 101, the garden tool further comprises a torsional spring 50, one end of the torsional spring 50 is fixed to the body 10, the other end is fixed to the connecting piece 1, when the adjusting assembly 40 is in the low gear, the torsional spring 50 is subjected to a torsional force to provide a rotating force during the process of adjusting from the low gear to the high gear; and when adjusting from the high gear to the low gear, the process can be assisted by the weight of the body 10.
