[0035] This utility model provides a handle assembly that can be used in garden tools such as lawnmowers or high-pole saws. The following description will use the handle assembly in a lawnmower as an example. Figures 1 to 7 A preferred embodiment of the handle assembly provided by this utility model is shown.

[0036] Please see Figure 1 and Figure 2In this embodiment, the handle assembly 100 includes: a connecting rod 1 extending along a first axis, a main handle 2 connected to one end of the connecting rod 1, and a rotation adjustment structure T disposed between the connecting rod 1 and the main handle 2. A locking member 3 is sleeved on the connecting rod 1, and a movable member 4 that cooperates with the locking member 3 is provided on the main handle 2. Adjusting the rotation adjustment structure T causes the locking member 3 to disengage from the movable member 4 to realize the rotational movement of the main handle 2 relative to the connecting rod 1.

[0037] Specifically, please refer to Figure 8 and Figure 9 The main handle 2 and the execution component 200 of the garden tool 1000 (i.e., the mowing component, which includes a mowing rope for mowing) are respectively located at both ends of the connecting rod 1. When using the garden tool 1000, the user can hold the main handle 2 and use the execution component 200 to trim the green vegetation and lawn. The connecting rod 1 extends along the first axis direction, which is defined as the front-to-back direction. The end of the connecting rod 1 with the execution component 200 is the front end of the connecting rod 1, and the end of the connecting rod 1 with the main handle 2 is the rear end of the connecting rod 1. The connecting rod 1 can be an aluminum tube, etc.

[0038] The main handle 2 is cylindrical in shape, extending in the front-to-back direction. The main handle 2 is sleeved on the rear end of the connecting rod 1. Optionally, please refer to [link to relevant documentation]. Figure 1 , Figure 8 and Figure 9 In this embodiment, a switch assembly 22 is provided on the main handle 2. The switch assembly 22 can be a trigger switch or the like. By providing the switch assembly 22 on the main handle 2, the power supply to the actuator 200 can be controlled by the switch assembly 22 when the user holds the main handle 2.

[0039] The specific location of the switch assembly 22 on the main handle 2 can be set according to the actual situation. Optionally, please refer to [link / reference needed]. Figure 1 , Figure 8 and Figure 9 In this embodiment, a handhold portion 24 is provided at the rear end of the main handle 2, and the switch assembly 22 is adjacent to the handhold portion 24 and located on the front side of the handhold portion 24. The handhold portion 24 is the part of the main handle 2 for the user to hold. By placing the switch assembly 22 close to the handhold portion 24, the user's hand can easily touch the switch assembly 22 when the user holds the handhold portion 24 of the main handle 2.

[0040] The main handle 2 and the connecting rod 1 are respectively provided with a movable part 4 and a locking part 3. When the main handle 2 is engaged with the connecting rod 1, the main handle 2 cannot rotate relative to the connecting rod 1 around the first axis; when the main handle 2 is disengaged from the connecting rod 1, the main handle 2 can rotate relative to the connecting rod 1 around the first axis. Please refer to [link to relevant documentation]. Figure 1 , Figure 8and Figure 9 A rotary adjustment structure T is provided between the main handle 2 and the connecting rod 1. Adjusting the rotary adjustment structure T allows the locking member 3 to disengage from the moving member 4, enabling the main handle 2 to be rotated relative to the connecting rod 1 along the forward and backward upward axial direction. Since the main handle 2 can be rotated relative to the connecting rod 1, the angle between the main handle 2 and the actuator 200 in the rotation direction of the main handle 2 can be adjusted.

[0041] When the garden tool 1000 is in mowing mode, the plane formed by the rotation of the mowing rope of the actuator 200 is parallel or nearly parallel to the ground. That is, the running direction of the actuator 200 is parallel or nearly parallel to the ground, while the main handle 2 faces the ground. The orientation of the handle 2 is the same as the orientation of the switch assembly 22, meaning the main handle 2 faces the ground. When the trimming function of the garden tool 1000 is needed, the entire garden tool 1000 in mowing mode is rotated so that the plane formed by the rotation of the mowing rope of the actuator 200 is perpendicular or nearly perpendicular to the ground. This means the running direction of the actuator 200 is perpendicular or nearly perpendicular to the ground, and the orientation of the main handle 2 is parallel or nearly parallel to the ground. At this point, the main handle 2 is rotated approximately 90° so that it continues to face the ground, thus switching the garden tool 1000 from mowing mode to trimming mode. When switching the working mode of the garden tool 1000, the user can rotate and adjust the main handle 2 of the garden tool 1000 according to the working mode after switching, so that the user can comfortably hold the main handle 2. This allows the user to comfortably hold and operate the garden tool 1000 in different working modes, which is more in line with ergonomics.

[0042] The handle assembly 100 of this utility model can rotate and adjust the main handle 2 through the rotation adjustment structure T. Thus, when switching the working mode of the garden tool 1000, the user can rotate and adjust the main handle 2 according to the garden tool 1000 after switching the working mode, so that the user can comfortably hold the main handle 2. This allows the user to comfortably hold and operate the garden tool 1000 in different working modes, which is more in line with ergonomics.

[0043] The main handle 2 can be rotated and adjusted by the rotary adjustment structure T. The specific setting of the rotary adjustment structure T can be set according to the actual situation. For example, the rotary adjustment structure T can be a threaded connection structure or a snap-fit ​​connection structure.

[0044] Optionally, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6In this embodiment, the rotation adjustment structure T includes: a movable member 4 slidably disposed on the main handle 2 along the first axis direction, and a locking member 3 sleeved on the connecting rod 1 and located on the sliding side of the movable member 4. The locking member 3 includes a limiting part 31, and the movable member 4 includes a mating part 41 that cooperates with the limiting part 31. The locking member includes at least one limiting part, and the movable member includes at least one mating part. The mating part cooperates with the limiting part to fix the main handle and the connecting rod in one of a plurality of rotational positions. At least one of the mating part 41 and the limiting part 31 is spaced apart along the rotational direction of the main handle 2.

[0045] Specifically, the locking element 3 is fixed to the connecting rod 1, while the movable element 4 is movably mounted on the main handle 2, allowing the main handle 2 to drive the movable element 4 to rotate relative to the connecting rod 1, and also allowing the movable element 4 to move relative to the main handle 2. Furthermore, within the travel range of the movable element 4 relative to the main handle 2, the movable element 4 has a locked position and an unlocked position.

[0046] At least one of the mating parts 41 and the limiting parts 31 is provided in multiples at intervals along the rotation direction of the main handle 2. When there are multiple mating parts 41, there may be one, two, three, four or more limiting parts 31. The following description will use an example where four mating parts 41 and four limiting parts 31 are evenly spaced along the rotation direction of the main handle 2.

[0047] Further, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 In this embodiment, when the movable part 4 is in the locked position, the limiting part 31 and the cooperating part 41 cooperate to restrict the rotational movement of the main handle 2 relative to the connecting rod 1; when the movable part 4 is in the unlocked position, the limiting part 31 and the cooperating part 41 disengage to realize the rotational movement of the main handle 2 relative to the connecting rod 1.

[0048] Specifically, when the movable part 4 is in the locked position, the four mating parts 41 on the movable part 4 respectively form a limiting engagement with the four limiting parts 31 on the locking part 3 in the rotation direction of the main handle 2. At this time, the handle assembly 100 is in a locked state, and the user cannot rotate or adjust the main handle 2. When the user needs to rotate or adjust the main handle 2, the movable part 4 in the locked position is moved to the unlocked position, so that the four mating parts 41 on the movable part 4 separate from the four limiting parts 31 on the locking part 3, thereby releasing the limiting engagement between the movable part 4 and the locking part 3 in the rotation direction of the main handle 2. At this time, the handle assembly 100 in the locked state switches to the unlocked state, and the user can rotate or adjust the main handle 2.

[0049] The specific movement settings of movable component 4 can be configured according to actual conditions. For example, movable component 4 can be configured to flip or slide relative to the main handle 2. Optionally, please refer to... Figure 2 and Figure 6 In this embodiment, the movable member 4 is slidably disposed on the main handle 2 along the axial direction of the connecting rod 1, and the locking member 3 is located on the side of the movable member 4 along the axial direction of the connecting rod 1.

[0050] Specifically, the movable part 4 is slidable back and forth relative to the main handle 2. The locking part 3 can be located in front of or behind the movable part 4. The following description uses the example of the movable part 4 being slidable back and forth behind the locking part 3. The rear end of the locking part 3 has a rearward-facing limiting part 31, and the front end of the movable part 4 has a forward-facing engaging part 41 corresponding to the limiting part 31. When the user needs to rotate and adjust the main handle 2, the movable part 4, located in the locked position, is slid backward to the unlocked position, allowing the four engaging parts 41 on the movable part 4 to separate from the four limiting parts 31 on the locking part 3. After rotating and adjusting the main handle 2 by 90°, the movable part 4, located in the unlocked position, is slid forward to the locked position, allowing the four engaging parts 41 on the movable part 4 to re-establish limiting engagement with the four limiting parts 31 on the locking part 3. At this time, the handle assembly 100 switches back to the locked state, thus completing the rotation adjustment of the main handle 2.

[0051] Optionally, please refer to Figure 2 In this embodiment, an elastic reset member 5 is provided between the movable member 4 and the main handle 2, and the movable member 4 can be reset to the locked position through the elastic reset member 5.

[0052] Specifically, the elastic reset member 5 can be a spring or the like, and it extends along the front-to-back direction, abutting against the front or rear side of the movable member 4. During the process of the user sliding the movable member 4 from the locked position to the unlocked position, the elastic reset member 5 is compressed or stretched. After the user completes the rotation adjustment of the main handle 2 and releases the movable member 4, the movable member 4 can automatically slide forward and reset to the locked position under the action of the elastic reset member 5, allowing the four mating parts 41 on the movable member 4 to automatically engage with the four limiting parts 31 on the locking member 3 to form a limiting engagement.

[0053] The mating part 41 and the limiting part 31 can form a limiting engagement. The specific arrangement of the mating part 41 and the limiting part 31 can be set according to the actual situation. For example, the mating part 41 and the limiting part 31 can be a magnetic engagement structure or a snap-fit ​​engagement structure, etc. Optionally, please refer to Figure 2 , Figure 4 and Figure 6In this embodiment, one of the mating part 41 and the limiting part 31 is a limiting protrusion 41a and the other is a limiting groove 31a. When the movable part 4 is in the locked position, the limiting protrusion 41a extends into the limiting groove 31a to limit the rotational movement of the main handle relative to the connecting rod. When the movable part 4 is in the unlocked position, the limiting protrusion 41a extends out of the limiting groove 31a to realize the rotational movement of the main handle relative to the connecting rod.

[0054] Specifically, the mating part 41 can be a limiting protrusion 41a, while the limiting part 31 can be a limiting groove 31a; alternatively, the mating part 41 can be a limiting groove 31a, while the limiting part 31 can be a limiting protrusion 41a. The following description will use the example of the mating part 41 being a limiting protrusion 41a and the limiting part 31 being a limiting groove 31a. The limiting part 31 and the mating part 41 are respectively the limiting groove 31a and the limiting protrusion 41a that can engage and mate. This arrangement of the limiting part 31 and the mating part 41 is relatively simple.

[0055] The locking member 3 has a rearward-facing limiting groove 31a on its rear end face, and the movable member 4 has a forward-facing limiting protrusion 41a on its front end face. When the movable member 4 is in the locked position, the limiting protrusion 41a extends into the limiting groove 31a, so that the limiting protrusion 41a and the limiting groove 31a form a locking engagement to restrict the rotation of the main handle 2 relative to the connecting rod 1. When the movable member 4 is in the unlocked position, the limiting protrusion 41a retracts out of the limiting groove 31a, and the locking member 3 and the movable member 4 are completely separated, allowing the main handle 2 to be rotated and adjusted relative to the connecting rod 1.

[0056] The shape of the limiting protrusion 41a is usually adapted to the shape of the limiting groove 31a. The limiting protrusion 41a can be square, trapezoidal, or triangular, etc. Optionally, please refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, the shape of the limiting protrusion 41a is adapted to the shape of the limiting groove 31a, and the size of the limiting groove 31a gradually decreases from the opening to the bottom in the rotation direction of the main handle 2.

[0057] Specifically, the dimensions of the limiting groove 31a and the limiting protrusion 41a in the rotational direction of the main handle 2 gradually decrease from front to back, making the limiting groove 31a a sloped groove and the limiting protrusion 41a a sloped protrusion. The sloped structure in the limiting groove 31a and the limiting protrusion 41a serves as a guide for the limiting protrusion 41a as it enters and exits the limiting groove 31a.

[0058] The specific shape and style of the movable component 4 are not particularly limited; it can be in the form of a block, cylinder, or strip, etc. Optionally, please refer to [link to relevant documentation]. Figure 2 and Figure 6 In this embodiment, the movable part 4 includes a cylindrical part 42 sleeved on the connecting rod 1 and located inside the main handle 2, an operating part 43 located at least partially outside the main handle 2 for the user to operate to push the movable part 4 to slide along the first axis direction, and a mating part 41 provided at one end of the cylindrical part 42 near the limiting part 31.

[0059] Specifically, a mounting hole is provided through the main handle 2. The movable member 4 is slidably disposed in the mounting hole of the main handle 2. One end of the movable member 4 is located inside the main handle 2 and is provided with a cylindrical portion 42 extending in the front-back direction. The cylindrical portion 42 and the connecting rod 1 form a sliding engagement in the front-back direction, thus guiding the movable member 4 in the front-back direction. An operating part 43 is provided at the end of the movable member 4 away from the cylindrical portion 42. The operating part 43 extends into the mounting hole, and at least a portion of the operating part 43 extends out of the mounting hole and into the outside of the main handle 2, so that the user can push the movable member 4 through the operating part 43.

[0060] Optionally, please refer to Figure 1 and Figure 2 In this embodiment, the movable member 4 is adjacent to the handgrip 24 and located on the front side of the handgrip 24. The movable member 4 and the switch assembly 22 are radially opposite each other on the connecting rod 1. By placing the movable member 4 close to the handgrip 24, the user's hand can easily touch the operating part 43 of the movable member 4 when the user holds the handgrip 24 of the main handle 2, making operation more convenient.

[0061] The specific shape and style of the locking element 3 are not particularly limited; the locking element 3 can be in the form of a block, cylinder, or strip, etc. Optionally, please refer to Figures 2 to 4 In this embodiment, the locking member 3 is arranged in a ring shape and is sleeved on the connecting rod 1. By making the locking member 3 ring-shaped, not only is the structure of the locking member 3 simpler, but the sleeved engagement between the locking member 3 and the connecting rod 1 also enables the installation and positioning of the locking member 3 and the connecting rod 1.

[0062] Further, please refer to Figures 2 to 4 In this embodiment, the locking member 3 is arranged in a ring shape, and a locking protrusion 32 is provided on the inner circumferential side of the locking member 3. The connecting rod 1 is provided with a slot 11 that cooperates with the locking protrusion 32. The locking protrusion and the slot cooperate to achieve circumferential fixation of the locking member and the connecting rod.

[0063] Specifically, the engaging engagement between the latching protrusion 32 and the latching groove 11 enables the connecting rod 1 and the locking member 3 to be positioned and limited in the circumferential direction of the connecting rod 1. Furthermore, the shape of the latching protrusion 32 and the shape of the latching groove 11 are typically compatible; for example, please refer to... Figures 2 to 4 In this embodiment, both the card protrusion 32 and the card slot 11 are arranged in the form of long strips extending in the front-back direction.

[0064] The specific number of protrusions 32 and slots 11 can be set according to actual needs. For example, there can be one, two, three, or more protrusions 32. Optionally, please refer to... Figures 2 to 4 In this embodiment, multiple card protrusions 32 and card slots 11 are evenly spaced along the circumference of the connecting rod 1.

[0065] Optionally, please refer to Figure 3 and Figure 4 In this embodiment, a rotation limiting part 23 is provided inside the main handle 2, and a first abutting part 33 and a second abutting part 34 are provided at intervals in the rotation direction of the main handle 2. The first abutting part 33 and the second abutting part 34 are respectively located on both sides of the rotation limiting part 23. The rotation angle of the main handle 2 is limited by the abutting cooperation between the rotation limiting part 23 and the first abutting part 33 and the second abutting part 34.

[0066] Specifically, when the garden tool 1000 is in the mowing mode, the main handle 2 is in the first position; when the garden tool 1000 is in the trimming mode, the main handle 2 is in the second position. The direction of rotating the main handle 2 from the first position to the second position is defined as the forward rotation direction, and the direction of rotating the main handle 2 from the second position to the first position is defined as the reverse rotation direction. A rotation limit part 23 can be provided on the main handle 2, while the first abutment part 33 and the second abutment part 34 are provided on the locking member 3. Alternatively, the rotation limit part 23 can be provided on the locking member 3, while the first abutment part 33 and the second abutment part 34 are provided on the main handle 2. Hereinafter, the rotation limit part 23 is provided on the main handle 2, and the first abutment part 33 and the second abutment part 34 are provided on the locking member 3 corresponding to the rotation limit part 23. During the rotation adjustment of the main handle 2, the rotation limit part 23 can move between the first abutment part 33 and the second abutment part 34.

[0067] When the garden tool 1000 is in mowing mode, the first abutment part 33 abuts against the rotation limit part 23 on the side facing the opposite direction of rotation. In this mode, the main handle 2 cannot be rotated in the opposite direction; it can only be rotated forward from the first position to the second position. When the garden tool 1000 is in trimming mode, the second abutment part 34 abuts against the rotation limit part 23 on the side facing the forward direction of rotation. In this mode, the main handle 2 cannot be rotated forward; it can only be rotated backward from the second position to the first position. Thus, through the cooperation between the rotation limit part 23, the first abutment part 33, and the second abutment part 34, the main handle 2 can be restricted to rotating only between the first and second positions.

[0068] The specific orientation of the rotation limiting part 23, the first abutting part 33, and the second abutting part 34 can be set according to actual conditions. The rotation limiting part 23, the first abutting part 33, and the second abutting part 34 can be abutting surfaces or abutting protrusions, etc. Optionally, please refer to... Figure 3 and Figure 4 In this embodiment, the first abutting part 33 and the second abutting part 34 are both abutting protrusions protruding from the outer peripheral side of the locking member 3, and the rotation limiting part 23 is a limiting groove provided on the inner shell wall of the main handle 2.

[0069] Optionally, please refer to Figure 1 and Figure 7 In this embodiment, the handle assembly 100 also includes a housing 6. One end of the connecting rod 1 is inserted into the housing 6. The housing 6 is connected to the end of the main handle 2 away from the rotation adjustment structure T. One of the housing 6 and the main handle 2 is provided with a first annular protrusion 21, and the other is provided with a first annular groove 61. The first annular protrusion 21 and the first annular groove 61 form a sliding fit in the rotation direction of the main handle 2.

[0070] Specifically, the rotation adjustment structure T is set at the front end of the main handle 2, and the rear end of the main handle 2 is sleeved with the front end of the housing 6. In this way, by setting the first annular protrusion 21 and the first annular groove 61 that slide between the main handle 2 and the housing 6, the main handle 2 can be rotated and guided to ensure that the main handle 2 will not be misaligned when rotating.

[0071] Optionally, please refer to Figure 1 and Figure 2 In this embodiment, the handle assembly 100 further includes a rotating positioning member 7 sleeved on the connecting rod 1. The rotating positioning member 7 is connected to one end of the main handle 2 near the rotating adjustment structure T. One of the rotating positioning member 7 and the main handle 2 is provided with a second annular protrusion, and the other is provided with a second annular groove. The second annular protrusion and the second annular groove form a sliding fit in the rotation direction of the main handle 2.

[0072] Specifically, the front end of the main handle 2 is sleeved with the rear end of the rotary positioning component 7. Thus, by setting a sliding fit between the main handle 2 and the rotary positioning component 7, the main handle 2 can also be rotated and guided to ensure that the main handle 2 will not be misaligned when it rotates.

[0073] This utility model also provides a garden tool, which can be a lawnmower or a high-branch saw, etc. The following description will take a lawnmower as an example. Figure 8 and Figure 9 A preferred embodiment of the handle assembly provided by this utility model is shown.

[0074] Please see Figure 8 and Figure 9 In this embodiment, the garden tool 1000 includes a handle assembly 100 and an execution component 200. The execution component 200 is disposed at the end of the connecting rod 1 in the handle assembly 100 away from the main handle 2. The orientation of the main handle 2 when the garden tool 1000 is in the first working mode is the same as the orientation when the garden tool 1000 is in the second working mode. The running direction of the execution component 200 when the garden tool 1000 is in the first working mode is different from the running direction when the garden tool 1000 is in the second working mode.

[0075] Specifically, the garden tool 1000 includes a handle assembly 100. Since the handle assembly 100 adopts the technical solution of the above embodiment, it has the beneficial effects brought about by the technical solution of the above embodiment. Because the handle assembly 100 is rotatable relative to the connecting rod 1, and the actuating component 200 is fixedly disposed at the front end of the connecting rod 1, the handle assembly 100 can be rotatable relative to the actuating component 200 to adjust and change the angle between the orientation of the main handle 2 and the running direction of the actuating component 200, thus enabling the garden tool 1000 to have multiple working modes. When the garden tool 1000 is in different working modes, the angle between the orientation of the main handle 2 and the running direction of the actuating component 200 is also different. The multiple working modes of the garden tool 1000 include a first working mode and a second working mode. The following will describe the first working mode as a grass-cutting mode and the second working mode as a trimming mode, respectively.

[0076] When the garden tool 1000 is in mowing mode, the plane formed by the rotation of the mowing rope of the actuator 200 is parallel or nearly parallel to the ground, meaning the direction of operation of the actuator 200 is parallel or nearly parallel to the ground, and the main handle 2 faces the ground. When the trimming function of the garden tool 1000 is needed, rotate the garden tool 1000 in mowing mode so that the plane formed by the rotation of the mowing rope of the actuator 200 is perpendicular or nearly perpendicular to the ground, meaning the direction of operation of the actuator 200 is perpendicular or nearly perpendicular to the ground. Then, move the movable part 4 on the main handle 2 to disengage it from the locking part 3. Then, rotate the main handle 2 90° clockwise so that the main handle 2 continues to face the ground, thus switching the garden tool 1000 from mowing mode to trimming mode. When the user no longer needs trimming, move the movable part 4 on the main handle 2 and then rotate the main handle 2 90° counterclockwise to switch the garden tool 1000 back to mowing mode.

[0077] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
