[0026] The limiting mechanism 3 is arranged in the middle of the bottom of the placing box 1, and limits the position of the supporting mechanism 2.

[0027] The supporting mechanism 2 comprises a rotating plate 21 rotatably connected to the bottom of the placing box 1, the position of the rotating plate 21 can be limited by the placing box 1, so that the rotating plate 21 can only rotate at the bottom of the placing box 1, one end of the rotating plate 21 is fixedly connected with a fixed rod 22, the position of the fixed rod 22 can be fixed by the rotating plate 21, the rotating rod can drive the fixed rod 22 to rotate, the inside of the fixed rod 22 is slidably connected with a supporting rod 23, the position of the supporting rod 23 can be limited by the fixed rod 22, so that the supporting rod 23 can only move in the inside of the fixed rod 22, a sliding groove matched with the supporting rod 23 is arranged in the inside of the fixed rod 22, so that the supporting rod 23 can move in the inside of the fixed rod 22, one side of the supporting rod 23 is rotatably connected with a first connecting piece 24, the position of the supporting rod 23 can be limited by the first connecting piece 24, so that the supporting rod 23 can only rotate in the inside of the first connecting piece 24, one end of the first connecting piece 24 is fixedly connected with a pushing rod 25, the position of the first connecting piece 24 can be fixed by the pushing rod 25, so that the position of the first connecting piece 24 will not change, the pushing rod 25 can drive the first connecting piece 24 to rotate, one side of the pushing rod 25 is rotatably connected with a second connecting piece 26, the position of the pushing rod 25 can be limited by the second connecting piece 26, so that the pushing rod 25 can only rotate in the inside of the second connecting piece 26, the second connecting piece 26 is fixedly connected in the inside of the fixed rod 22, and the position of the second connecting piece 26 can be fixed by the fixed rod 22.

[0028] The supporting rod 23 can move downwards to press the pushing piece through the first connecting piece 24, and rotate outwards with the second connecting piece 26 as the center, the pushing piece rotates in the inside of the fixed rod 22 through the second connecting piece 26, and the pushing piece rotates to drive the supporting rod 23 to rotate in the inside of the fixed rod 22 through the first connecting piece 24.

[0029] A first hollow groove matched with the pushing rod 25 is arranged in the inside of the fixed rod 22, so that the pushing rod 25 can rotate in the inside of the fixed rod 22, and a second hollow groove matched with the supporting rod 23 is arranged on the surface of the fixed rod 22, so that the supporting rod 23 can be connected with the fixed rod 22.

[0030] The first hollow groove and the second hollow groove can facilitate the pushing rod 25 and the supporting rod 23 to rotate and move in the inside of the fixed rod 22, so that the supporting mechanism 2 is opened to support the device.

[0031] One end of the support rod 23 is fixedly connected to the abutment plate 4. The support rod 23 can fix the position of the abutment plate 4. The rotation and movement of the support rod 23 can drive the abutment plate 4 to rotate and move. A sliding ring 5 is slidably connected to the side of the fixed rod 22 near the abutment plate 4. The fixed rod 22 can restrict the position of the sliding ring 5, restricting the sliding ring 5 to move only on the surface of the fixed rod 22.

[0032] The sliding ring 5 moves downward, pushing the contact plate 4 downward. The downward movement of the contact plate 4 can drive the support rod 23 to move inside the fixed rod 22. The sliding ring 5 is the driving component of the support mechanism 2. The movement of the sliding ring 5 can open the support mechanism 2.

[0033] A spring rod 6 is fixedly connected to one side of the surface of the fixed rod 22. The fixed rod 22 can fix the position of the spring rod 6 to ensure that the position of the spring rod 6 does not change when it extends or retracts. A limiting plate 7 is fixedly connected to one end of the spring rod 6. The spring rod 6 can fix the position of the limiting plate 7. The movement of the limiting plate 7 can squeeze the spring rod 6. The return of the spring rod 6 can drive the limiting plate 7 to return to its original position. A third slot adapted to the limiting plate 7 is opened on one side of the surface of the fixed rod 22. The third slot can facilitate the movement of the surface of the limiting plate 7.

[0034] The limiting plate 7 restricts the position of the sliding ring 5 to ensure that the sliding ring 5 will not move due to the influence of the abutment plate 4. The movement of the sliding ring 5 squeezes the limiting plate 7, pushing the limiting plate 7 to move inward into the fixed rod 22.

[0035] The limiting mechanism 3 includes a fixed ring 31 fixedly connected to the bottom of the placement box 1. The placement box 1 can fix the position of the fixed ring 31. A limiting plate 32 is slidably connected inside the fixed ring 31. The fixed ring 31 can restrict the position of the limiting plate 32, restricting the limiting plate 32 to move only inside the fixed ring 31. A connecting rod 33 is fixedly connected to the bottom of the limiting plate 32. The limiting plate 32 can fix the position of the connecting rod 33. The movement of the connecting rod 33 can drive the limiting plate 32 to move. A rotating ring 34 is rotatably connected to the bottom of the fixed ring 31. The fixed ring 31 can restrict the position of the rotating ring 34, restricting the rotating ring 34 to rotate only at the bottom of the fixed ring 31.

[0036] Twisting the rotating ring 34 causes the rotating ring 34 to press the connecting rod 33 to move. The movement of the connecting rod 33 causes the limiting plate 32 to move inside the fixed ring 31. The limiting plate 32 can restrict the position of the rotating plate 21, ensuring that the rotating plate 21 will not rotate when not needed.

[0037] The bottom of the fixed ring 31 is provided with a straight groove 8 that is adapted to the connecting rod 33. The straight groove 8 facilitates the movement of the connecting rod 33 at the bottom of the fixed ring. The surface of the rotating ring 34 is provided with an arc groove 9 that is adapted to the connecting rod 33. The arc groove 9 facilitates the movement of the connecting rod 33 inside the rotating ring 34.

[0038] The rotating ring 34 can be rotated to push the connecting rod 33 placed inside it to move through the arc groove 9, and the straight groove 8 can guide the movement of the connecting rod 33.

[0039] Example 2

[0040] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the placement box 1 is fixedly connected to the bottom of the placement box 10. The placement box 10 can fix the position of the placement box 1, support the placement box 10, place the tester, and test the AC / DC charging device.

[0041] The following section provides a further introduction to the specific working method, as detailed in the description below: Specifically, when the portable AC / DC charging device tester is in operation,

[0042] Twisting the rotating ring 34 causes it to push the connecting rod 33 to move through the arc groove 9. The movement of the connecting rod 33 causes the limiting plate 32 to move inward within the fixed ring 31, releasing the limiting plate 32 from restricting the rotating plate 21. Moving the sliding ring 5 then pushes the contact plate 4 downward. The downward movement of the contact plate 4 pushes the support rod 23 to move inside the fixed rod 22. The downward movement of the support rod 23 can cause the first connecting member 24 to press the pushing member to rotate outward around the second connecting member 26. The pushing member then rotates outward through the second connecting member 26. The component 26 rotates inside the fixed rod 22. The rotating component pushes the support rod 23 to rotate inside the fixed rod 22 through the first connecting component 24, causing the support rod 23 to open in an umbrella shape to support the device. While the sliding ring 5 is moving, the sliding ring 5 moves downward on the surface of the fixed rod 22 to press the limiting plate 7, pushing the limiting plate 7 to move inward into the fixed rod 22 and press the spring rod 6. When the moving ring passes the limiting plate 7, the spring rod 6 drives the limiting plate 7 to stop, and the limiting plate 7 restricts the position of the sliding ring 5.
