[0035] Please refer to Figures 1 to 3 In the present embodiment, the adapter assembly 100 includes a first pipe joint 1, a second pipe joint 2 connected to one end of the first pipe joint 1, and a locking member 7 for connecting the first pipe joint 1 and the second pipe joint 2. The first pipe joint 1 includes a first connecting portion 11 and a switch 4 located inside the first pipe joint 1. The second pipe joint 2 includes a second connecting portion 21 and an abutting portion 22 for cooperating with the switch 4. The locking member 7 connects the first connecting portion 11 and the second connecting portion 21 to detachably fix the first pipe joint 1 relative to the second pipe joint 2. The abutting portion 22 extends from the second connecting portion 21 towards the first connecting portion 11, and the abutting portion 22 at least partially overlaps the second connecting portion 21 to turn on or turn off the switch 4.

[0036] Specifically, the first pipe joint 1 and the second pipe joint 2 are both provided in a cylindrical shape, and the second pipe joint 2 is detachably connected with the first pipe joint 1 through the locking member 7, so that the first pipe joint 1 and the second pipe joint 2 have a docking state and a disengaged state. When the first pipe joint 1 and the second pipe joint 2 are in the disengaged state, the first pipe joint 1 and the second pipe joint 2 can be completely separated; or the first pipe joint 1 and the second pipe joint 2 can be partially connected, and the remaining part is separated. For example, one end of the second pipe joint 2 is usually rotatably connected with one end of the first pipe joint 1, so that the second pipe joint 2 can rotate relative to the first pipe joint 1, and the rotation axis of the second pipe joint 2 is perpendicular or approximately perpendicular to the axial direction of the second pipe joint 2. In the rotation stroke of the second pipe joint 2 relative to the first pipe joint 1, the second pipe joint 2 has a docking position and a folded position. When the first pipe joint 1 and the second pipe joint 2 are in the docking state, the second pipe joint 2 is located at the docking position, the two ends of the second pipe joint 2 close to each other are docked, the end faces of the second pipe joint 2 close to each other abut, and the second pipe joint 2 is coaxially arranged with the first pipe joint 1. When the first pipe joint 1 and the second pipe joint 2 are in the disengaged state, the second pipe joint 2 is located at the folded position, the second pipe joint 2 is located on one side of the first pipe joint 1 in the rotation direction of the second pipe joint 2, the end faces of the second pipe joint 2 close to each other are separated, and the central axis of the second pipe joint 2 is arranged at a preset angle A with the central axis of the first pipe joint 1, where 0°≤A<180°, for example, A can be 0°, 10°, 30°, or 45°, etc. In the following, the rotatable connection between one end of the second pipe joint 2 and one end of the first pipe joint 1 will be introduced as an example.

[0037] A rotatable connection structure is arranged between the two ends of the second pipe joint 2 close to each other and the first pipe joint 1, so that the second pipe joint 2 can rotate relative to the first pipe joint 1. The specific arrangement of the rotatable connection structure between the second pipe joint 2 and the first pipe joint 1 can be set according to the actual situation. Alternatively, please refer to Figures 1 to 3 and Figure 2 In this embodiment, a first rotatable connection lug 12 is protrudingly arranged on the outer peripheral side surface of the first pipe joint 1, a second rotatable connection lug 24 is protrudingly arranged on the outer peripheral side surface of the second pipe joint 2 corresponding to the first rotatable connection lug 12, and the first rotatable connection lug 12 and the second rotatable connection lug 24 are rotatably connected through a rotation shaft. That is, the rotatable connection structure between the second pipe joint 2 and the first pipe joint 1 is composed of the first rotatable connection lug 12, the second rotatable connection lug 24, and the rotation shaft, and the arrangement of this rotatable connection structure is relatively simple.

[0038] The first pipe joint 1 is sleeved on the first connecting rod 200 at an end away from the second pipe joint 2, and the second pipe joint 2 is sleeved on the first connecting rod 200 at an end away from the first pipe joint 1. In this way, the adapter assembly 100 is arranged between the first connecting rod 200 and the second connecting rod 300, so that the adapter assembly 100, the first connecting rod 200 and the second connecting rod 300 are assembled into an operating rod of the garden tool, so that the garden tool can be folded.

[0039] The first pipe joint 1 is sleeved on the first connecting rod 200 at an end away from the second pipe joint 2, and the second pipe joint 2 is sleeved on the first connecting rod 200 at an end away from the first pipe joint 1. In this way, the adapter assembly 100 is arranged between the first connecting rod 200 and the second connecting rod 300, so that the adapter assembly 100, the first connecting rod 200 and the second connecting rod 300 are assembled into an operating rod of the garden tool, so that the garden tool can be folded.

[0040] The first connecting part 11 can be arranged on the first pipe joint 1 according to actual conditions, for example, the first connecting part 11 and the first rotating connecting lug 12 are arranged at intervals along the circumference of the first pipe joint 1, and the included angle between the first connecting part 11 and the first rotating connecting lug 12 can be 90°, 180° or 270°, etc. Alternatively, please refer to Figure 3 In this embodiment, the position of the first connecting part 11 and the first pipe joint 1 rotatingly connecting the second pipe joint 2 is opposite in the radial direction of the first pipe joint 1. That is, the included angle between the first connecting part 11 and the first rotating connecting lug 12 is 180° or approximately 180°, and this arrangement of the first connecting part 11 and the first rotating connecting lug 12 is relatively reasonable.

[0041] The specific arrangement of the first connecting part 11 can also be set according to actual conditions, for example, the first connecting part 11 can be part of the pipe wall of the first pipe joint 1, etc. Alternatively, please refer to Figure 2 In this embodiment, the first connecting part 11 is a first connecting lug 11a protruding from the outer periphery of the first pipe joint 1. The first connecting part 11 is arranged as the first connecting lug 11a protruding from the outer periphery of the first pipe joint 1, which facilitates the connection of the first connecting part 11 and the second connecting part 21. The first connecting part 11 will be taken as an example for introduction below.

[0042] Similarly, the specific arrangement position of the second connecting portion 21 on the second pipe joint 2 can be set according to actual conditions. For example, the second connecting portion 21 and the second rotating connecting lug 24 are arranged at intervals along the circumference of the second pipe joint 2, and the included angle between the second connecting portion 21 and the second rotating connecting lug 24 can be 90°, 180°, or 270°, etc. Alternatively, please refer to Figure 2 In the embodiment, the position where the second connecting portion 21 and the second pipe joint 2 rotate to connect the first pipe joint 1 is opposite in the radial direction of the second pipe joint 2. That is, the included angle between the second connecting portion 21 and the second rotating connecting lug 24 is 180° or approximately 180°, and this arrangement of the second connecting portion 21 and the second rotating connecting lug 24 is relatively reasonable.

[0043] The specific arrangement of the second connecting portion 21 can also be set according to actual conditions. For example, the second connecting portion 21 can be part of the pipe wall of the second pipe joint 2, etc. Alternatively, please refer to Figures 2 to 5 In the embodiment, the second connecting portion 21 is configured as a second connecting lug 21a protruding from the outer periphery of the second pipe joint 2. By arranging the second connecting portion 21 as the second connecting lug 21a protruding from the outer periphery of the second pipe joint 2, it is convenient to connect the second connecting portion 21 with the first connecting portion 11, and the following will be introduced taking the second connecting portion 21 as the second connecting lug 21a as an example.

[0044] Alternatively, please refer to Figures 2 to 5 In the embodiment, when the second pipe joint 2 is in the docking position, the first connecting lug 11a abuts on one side of the second connecting lug 21a in the direction of the rotating axis of the second pipe joint 2. In this way, when the second pipe joint 2 is in the folded position, the first connecting lug 11a is separated from the second connecting lug 21a. When the second pipe joint 2 is in the docking position, the second connecting lug 21a abuts on one side of the first connecting lug 11a in the direction of the rotating axis of the second pipe joint 2, so that the docking of the first pipe joint 1 and the second pipe joint 2 in the direction of the rotating axis of the second pipe joint 2 can be limited, so as to ensure the coaxiality when the first pipe joint 1 and the second pipe joint 2 are docked.

[0045] When the first pipe joint 1 and the second pipe joint 2 are in the docking state, the second connecting lug 21a is detachably connected to the first connecting lug 11a by the locking member 7, so as to realize the detachable connection between the first pipe joint 1 and the second pipe joint 2. Alternatively, please refer to Figure 2 In the embodiment, the first connecting lug 11a and the second connecting lug 21a are provided with through holes corresponding to each other, and when the first pipe joint 1 and the second pipe joint 2 are in the docking state, the locking member 7 passes through the through holes of the first connecting lug 11a and the second connecting lug 21a and is screwed with the second connecting lug 21a.

[0046] Specifically, the head of the locking member 7 is usually provided with a knob 71, so that the user can rotate the locking member 7 through the knob 71, and the tail of the locking member 7 is provided with external threads. The tail of the locking member 7 can pass through the first connecting ear 11a and be screwed with the second connecting ear 21a, or the tail of the locking member 7 can pass through the second connecting ear 21a and be screwed with the first connecting ear 11a. Hereinafter, the tail of the locking member 7 passing through the second connecting ear 21a and being screwed with the first connecting ear 11a will be taken as an example for description.

[0047] The locking member 7 is rotatably arranged on the second connecting ear 21a, and a threaded hole (i.e. a through hole) is arranged on the first connecting ear 11a corresponding to the tail of the locking member 7. When the second pipe joint 2 is in the docking position, the head of the locking member 7 is located on the side of the second connecting ear 21a away from the first connecting ear 11a. If the locking member 7 is tightened, the tail of the locking member 7 is screwed into the threaded hole on the first connecting ear 11a. At this time, the first connecting ear 11a and the second connecting ear 21a are fixedly connected through the locking member 7, and the second pipe joint 2 cannot rotate relative to the first pipe joint 1. If the locking member 7 is loosened, the tail of the locking member 7 is withdrawn from the threaded hole on the first connecting ear 11a. At this time, the first connecting ear 11a and the second connecting ear 21a are not fixedly connected, and the second pipe joint 2 can rotate relative to the first pipe joint 1, so that the second pipe joint 2 can be rotated to the folded position. Hereinafter, the fixing and loosening of the adapter assembly 100 by rotating the knob 71 will be taken as an example for description.

[0048] The switch 4 is arranged in the first pipe joint 1. The switch 4 is a press switch, for example, the switch 4 can be a micro switch or the like. The switch 4 has a contact 41. When the contact 41 is pressed, the switch 4 can be triggered to be turned on. When the first pipe joint 1 and the second pipe joint 2 are in the docking state, the second pipe joint 2 is in the docking position, the first connecting part 11 and the second connecting part 21 are fixedly connected through the locking member 7, and the abutting part 22 on the second pipe joint 2 abuts against the contact 41 of the switch 4, so that the switch 4 is turned on. At this time, the garden tool can be powered on to work. After the first connecting part 11 and the second connecting part 21 are disassembled, the second pipe joint 2 in the docking position is rotated to the folded position, the abutting part 22 on the second pipe joint 2 is separated from the switch 4, so that the switch 4 is turned off. At this time, the garden tool cannot be powered on to work, thereby preventing personal injury caused by misoperation after the garden tool is folded, and facilitating the transportation, carrying and storage of the garden tool.

[0049] The adapter assembly 100 is arranged between the first connecting rod 200 and the second connecting rod 300 of the garden tool, so that the garden tool can be folded, and when the garden tool is unfolded, the abutting portion 22 of the second pipe joint 2 can abut against the trigger switch 4, so that the garden tool can normally work in the power-on state; when the garden tool is folded, the abutting portion 22 of the second pipe joint 2 is separated from the switch 4, the switch 4 is disconnected, and the garden tool cannot work, so that the garden tool can be prevented from being misoperated to cause personal injury after being folded, and the garden tool is convenient to transport, carry and store.

[0050] Optionally, referring to Figures 2 to 5 In the embodiment, the first pipe joint 1 comprises a touch piece 3 between the abutting portion 22 and the switch 4, when the first pipe joint 1 and the second pipe joint 2 are in the butt joint state, the locking piece 7 connects the first connecting portion 11 and the second connecting portion 21, the abutting portion 22 abuts against the touch piece 3 to turn on the switch 4; when the first pipe joint 1 and the second pipe joint 2 are in the separated state, the first connecting portion 11 and the second connecting portion 21 are separated, and the abutting portion 22 is separated from the touch piece 3 to turn off the switch 4.

[0051] Specifically, the touch piece 3 is arranged in the first pipe joint 1, and the touch piece 3 can slide relative to the first pipe joint 1. The specific arrangement of the sliding direction of the touch piece 3 can be set according to the actual situation, for example, the sliding direction of the touch piece 3 can be the radial direction of the first pipe joint 1; the sliding direction of the touch piece 3 can also be a direction parallel or approximately parallel to the radial direction of the first pipe joint 1. Optionally, referring to Figures 2 to 5 In the embodiment, the sliding direction of the touch piece 3, the central axis of the first pipe joint 1 and the rotation axis of the second pipe joint 2 are perpendicular, so that the movement direction of the touch piece 3 is arranged, so that the internal structure of the first pipe joint 1 is not easy to interfere with the sliding of the touch piece 3.

[0052] In the sliding stroke of the touch piece 3 relative to the first pipe joint 1, the touch piece 3 has a trigger position and a release position. The switch 4 is located on one side of the touch piece 3 in the sliding direction, so that the touch piece 3 and the switch 4 can approach and move away from each other. The switch 4 is arranged in the first pipe joint 1 with the contact 41 facing the touch piece 3, and the contact 41 is located in the sliding stroke of the touch piece 3, so that the switch 4 is turned on by the touch piece 3. When the touch piece 3 is in the trigger position, one end of the touch piece 3 abuts against the contact 41, so that the switch 4 is turned on. When the touch piece 3 is in the release position, the touch piece 3 is separated from the contact 41, so that the switch 4 is turned off.

[0053] The second pipe joint 2 is provided with an abutting portion 22, and the end of the touch piece 3 away from the switch 4 is correspondingly arranged with the abutting portion 22 on the second pipe joint 2, so that in the process of rotating the second pipe joint 2 to the docking position, the abutting portion 22 on the second pipe joint 2 gradually approaches the touch piece 3 in the released position, so that the abutting portion 22 abuts on the side of the touch piece 3 away from the switch 4, so that the abutting portion 22 drives the touch piece 3 to slide, and when the second pipe joint 2 is rotated to the docking position, the abutting portion 22 drives the touch piece 3 to slide to the triggering position, thereby triggering the switch 4 to be turned on; in the process of rotating the second pipe joint 2 to the folding position, the abutting portion 22 on the second pipe joint 2 gradually moves away from the touch piece 3 in the triggering position, so that the abutting portion 22 is separated from the touch piece 3, and the touch piece 3 slides towards the released position, so that the touch piece 3 is separated from the switch 4, thereby turning off the switch 4.

[0054] The touch piece 3 and the switch 4 are arranged in the first pipe joint 1, and the touch piece 3 and the switch 4 can be arranged on the inner pipe wall of the first pipe joint 1; the touch piece 3 and the switch 4 can also be arranged on a component in the first pipe joint 1. Optionally, please refer to Figures 2 to 5 In this embodiment, the first pipe joint 1 is provided with a mounting piece 6, the touch piece 3 is slidingly arranged on the mounting piece 6, and the switch 4 is arranged on the mounting piece 6 and located on one side of the touch piece 3 in the sliding direction. The touch piece 3 and the switch 4 can be first mounted on the mounting piece 6 to form an assembly, and then the assembly is integrally mounted in the first pipe joint 1, so that the installation difficulty of the touch piece 3 and the switch 4 can be reduced, and the cooperation precision between the touch piece 3 and the switch 4 can be ensured.

[0055] Optionally, please refer to Figure 5 In this embodiment, the first pipe joint 1 is provided with an elastic piece 5, one end of the elastic piece 5 abuts on the touch piece 3, and the other end of the elastic piece 5 abuts on the first pipe joint 1 or the switch 4, and the touch piece 3 is reset by the elastic piece 5.

[0056] Specifically, the elastic piece 5 can be a spring or the like, and the following will be introduced by taking the elastic piece 5 as a spring as an example. The elastic piece 5 is arranged to extend along the sliding direction of the touch piece 3, and one end of the elastic piece 5 abuts on the touch piece 3. The end of the elastic piece 5 away from the touch piece 3 can abut on the inner pipe wall of the first pipe joint 1, that is, the elastic piece 5 is arranged between the touch piece 3 and the inner pipe wall of the first pipe joint 1; the end of the elastic piece 5 away from the touch piece 3 can also abut on the switch 4, that is, the elastic piece 5 is arranged between the touch piece 3 and the switch 4.

[0057] In the process of the abutting portion 22 driving the touch piece 3 in the releasing position to the triggering position, the elastic member 5 will be compressed or stretched, and after the touch piece 3 is separated from the abutting portion 22, the touch piece 3 in the triggering position can be automatically slid back to the releasing position under the action of the elastic member 5, so as to separate the touch piece 3 from the switch 4, and make the switch 4 off. The following will take the sliding back of the touch piece 3 by the elastic member 5 as an example for introduction.

[0058] In the process of the rotation of the second pipe joint 2, the abutting portion 22 on the second pipe joint 2 can enter the first pipe joint 1 to realize the sliding of the touch piece 3 in the first pipe joint 1 by the abutting portion 22. The abutting portion 22 can enter the first pipe joint 1 from the port on the end face of the first pipe joint 1 close to the second pipe joint 2; the abutting portion 22 can also enter the first pipe joint 1 from the opening on the outer circumferential side of the first pipe joint 1.

[0059] The specific setting position of the abutting portion 22 on the second pipe joint 2 can be set according to the actual situation. Optionally, please refer to Figures 3 to 5 In the embodiment, the second connecting lug 21a includes an extension portion 23 extending along the axial direction of the second pipe joint 2 and towards the first pipe joint 1, and the abutting portion 22 is arranged at the end of the extension portion 23 away from the second connecting lug 21a.

[0060] Specifically, the end of the first pipe joint 1 close to the second pipe joint 2 is provided with a through hole 13 penetratingly arranged, and the through hole 13 is opposite to the first rotating connecting lug 12 in the radial direction of the first pipe joint 1. The end of the second connecting lug 21a away from the second rotating connecting lug 24 extends to form an extension portion 23 along the direction from the end of the second pipe joint 2 away from the first pipe joint 1 to the end close to the first pipe joint 1, and the extension portion 23 is a cantilever structure. When the second pipe joint 2 is in the docking position, the extension portion 23 is located on the side of the first pipe joint 1 close to the through hole 13 in the radial direction, and at least part of the abutting portion 22 on the extension portion 23 enters the first pipe joint 1 from the through hole 13 to abut the touch piece 3.
