[0043] Preferably, the locking end 2321 and the fixing plate 231 are placed on the same plane. Fig.10 shown.

[0044] The rotary piece 13 and the limit piece 24 adopt the above-mentioned special-shaped structure, so that the rotary piece 13 can be inserted into the slot 26 and can be rotated and guided at the same time. After rotating into place, the first contact piece 11 and the second contact piece 21 are aligned.

[0045] The power supply has a variety of structures: Example 1: The power supply body includes a first shell 3 with an open structure at one end, and the end cover 23 is fixed on the opening structure to achieve sealing of the opening structure.

[0046] Example 2: The power source body includes a second housing 41 and a fixing structure 42 disposed on the second housing for fixing the rotor 13 .

[0047] With the above structure, in order to prevent the rotary vane from rotating after it is rotated into place, a locking hole 28 is provided on the end cover 23, and correspondingly, an adjusting groove is provided at the end of the second shell that contacts the first shell and corresponds to the locking hole 28, and a locking rod 16 that can be placed in the locking hole 28 is provided in the adjusting groove, and a spring 17 is provided between the locking rod 16 and the bottom of the adjusting groove; an adjusting hole connected to the adjusting groove is provided on the side wall of the second shell, and a control part 18 connected to the locking rod 16 for controlling the movement of the locking rod 16 along the adjusting groove is provided in the adjusting hole.

At this time, one end of the locking rod 16 is placed at the lowest point of the ramp structure 281. Fig.13 The rotary vane is rotated clockwise as shown, so that the insertion end is inserted into the slot 26 between the insertion end 2421 and the end cover 23. The rotary vane is continuously rotated. During the rotation process, under the guidance of the stopper 24 and the rotary vane 13, the first contact member 11 and the corresponding second contact member 21 gradually approach and align, and the lock rod 16 retracts the compression spring under the action of the ramp structure 281. Fig.13 , 14 As shown, when the rotary vane abuts against the anti-rotation structure 27, the first contact piece 11 is aligned with its corresponding second contact piece 21. At this time, the locking rod is aligned with the locking hole 28. Under the action of the spring, the locking rod is extended and placed in the locking hole 28 to achieve rotation locking of the rotary vane, prevent loosening, and resist vibration and impact.

[0052] When the battery needs to be replaced, push the control unit 18 away from the locking hole 28 to disengage the locking rod from the locking hole 28, and then turn the rotary piece (i.e., the radio body) counterclockwise to return to the locking position. Fig.12 The power supply can be removed from the position shown in the figure.
