Similar to the first barb 401b, since one end of the first baffle 401c-1 is fixed and the other end is suspended, and the first baffle 401c-1 is in a sheet shape, not in a block shape, a distance of 2-3 mm is provided between the first baffle 401c-1 and the second side 401c, so that the first baffle 401c-1 has elastic potential energy to a certain extent.

The second groove 401d-1 is provided to allow the baffle plate on the third side 401d to elastically deform. Similar to the first plate 401c-1, one end of the plate on the third side 401d is fixed, the other end is suspended because of the second groove 401d-1, and the plate is in a shape of a sheet, not a block, so that the plate has elastic potential energy to a certain extent.

In this embodiment, the swivel member 502 and the connecting member 501 can be easily removed. Specifically, the rotating member 502 of the rotating member 502 is disposed in the first accommodating space C through the connecting member 501, and an L-shaped groove 502a is provided at a port where the rotating member 502 of the rotating member 502 and the connecting member 501 are connected to each other. The second protrusion 501d extends inward from the port of the second through hole 501c, and cooperates with the L-shaped slot 502a to limit the vertical position of the rotating member 502. The rotating member 502 is further provided with a third through hole 502b, wherein when the rotating member 502 is inserted into the connecting member 501, the fourth through hole 501e is communicated with the third through hole 502b, the third side surface 401d is further provided with a fourth protrusion 401d-3, and the fourth protrusion 401d-3 is just inserted into the fourth through hole 501e and the third through hole 502 b.

Preferably, the inside of the rotating member 502 is in a T-shaped hollow shape, a telescopic rod 502c and a stirring block 502d are arranged in the T-shaped hollow shape, the telescopic rod 502c penetrates through the stirring block 502d to be connected with the connecting member 501, and specifically, an external thread of the telescopic rod 502c is connected with an internal thread of the stirring block 502d in a matched manner;

the further telescopic rod 502c comprises a front limit gasket 502c-1 and a rear limit gasket 502c-2, an elastic piece 502c-3 is arranged between the front limit gasket 502c-1 and the rear limit gasket 502c-2, a second conductive copper sheet 502c-4 is arranged at the other end of the front limit gasket 502c-1, and one end of the second conductive copper sheet 502c-4 is connected with a second lead 502c-5 penetrating through the telescopic rod 502 c; wherein, the outer ring of the front limit gasket 502c-1 is embedded and fixed with the inner wall of the rotating piece 502; wherein, the second conductive copper sheet 502c-4 is matched with the first conductive copper sheet 401c-11 to realize power on.

During installation, the rotating shaft 501a is pressed downwards along the direction from the front surface A to the back surface B, because the first barb 401B can generate elastic deformation, the rotating shaft 501a can pass through the barb and is placed at a bayonet with a central angle larger than 270 degrees formed by dislocation between the hook position of the first barb 401B and the bottom end of the first groove 401a-1, and because the barb is bent, the rotating shaft 501a cannot be separated from the bayonet generated by dislocation under the condition of no external force, so that the rotating shaft 501a is limited. The rotating member 502 and the connecting member 501 are connected to each other, and thus the rotating shaft 501a is restrained in the moving direction while also performing a rotating motion. In view of this, the second fitting 500 is clamped by the first through hole 501b fitting with the first conductive copper sheet 401c-11, and the first conductive copper sheet 401c-11 contacts with the second conductive copper sheet 502c-4, so that the second fitting 500 is in a horizontal state and is in a powered condition.

In use, assuming a horizontal position in an initial state, the second conductive wire 502c-5 is electrified, and the second conductive wire 502c-5 conducts electricity to the second conductive copper sheet 502c-4, because the first through hole 501b and the first conductive copper sheet 401c-11 are mutually matched and clamped when in the horizontal position, the rotating piece 502 and the connecting piece 501 are locked in the horizontal position, and the first conductive copper sheet 401c-11 is contacted with the second conductive copper sheet 502c-4 to achieve electricity taking.

When the power is not needed to be disconnected, the toggle block 502d protruding on the outer rotary piece 502 is pushed, at this time, because the outer ring of the front limit gasket 502c-1 is embedded and fixed with the inner wall of the rotary piece 502, the telescopic rod 502c abuts against the first conductive copper sheet 401c-11, at this time, the second matching piece 500 is rotated anticlockwise, so that the first baffle 401c-1 leaves the first through hole 501b, and because the first baffle 401c-1 has certain elastic potential energy, the first baffle 401c-1 is not broken when in rotation, only a relative resistance is generated, namely the first conductive copper sheet 401c-11 is separated from the second conductive copper sheet 502c-4, so that power failure is realized, because the elastic piece 502c-3 enables the telescopic rod 502c to reset automatically after the pressed telescopic rod 502c is released, the first protrusion 401d-2 and the first through hole 501b are mutually buckled after the anticlockwise rotation by 90 degrees, and the second matching piece 500 is in a vertical state and is in a stable power failure condition.

When the device is not in use or is to be removed for storage, the rotating member 502 can be removed from the connecting member 501 by rotating the second mating member 500 counterclockwise until the fourth protrusion 401d-3 exits the fourth through-hole 501e and the third through-hole 502 b.
