The charging state diagram is as shown in FIG. Figure 6 As shown. A charging socket is arranged on the bottom shell 1 at a position corresponding to the charging socket 12, and the charging socket 12 is located in the charging socket. The circuit board 2 is also electrically connected to a charging indicator light 13, and a lamp hole is arranged on the bottom shell 1 at a position corresponding to the charging indicator light 13, and the charging indicator light 13 is located in the lamp hole.

[0028] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the lower end of the bottom shell 1 is open, and an internal thread structure is provided on the inner wall of the lower end, and a bottom cover 11 is threadedly installed on the internal thread structure. The first spring 4 and the movable housing 5 are sleeved on the outer side of the upper end of the bottom shell 1. The first spring 4 is located between the bottom shell 1 and the movable housing 5. An annular step portion supporting the lower end of the first spring 4 is provided on the outer wall of the bottom shell 1. An annular boss portion 501 is provided on the inner wall of the movable housing 5. The upper end of the first spring 4 is pressed against the lower end surface of the annular boss portion 501, so the first spring 4 always applies an upward elastic force to the movable housing 5. An annular groove 502 is also provided on the inner wall of the movable housing 5. The annular groove 502 is located on the upper side of the annular boss portion 501, and a connecting inclined surface 503 is provided between the annular groove 502 and the annular boss portion 501. The upper end of the bottom shell 1 is provided with a plurality of positioning circular holes along the circumferential direction, and a plurality of balls 6 corresponding to the positioning circular holes are provided in the annular groove 502. A limit stop bar protrusion, a limit stop bar and other structures are provided on both sides of the ball 6 in the annular groove 502 and on the connecting inclined surface 503, so that the ball 6 can only enter the connecting inclined surface 503 from the annular groove 502, or enter the annular groove 502 from the connecting inclined surface 503, so that the ball 6 cannot roll along the annular groove 502 or along the circumferential direction of the connecting inclined surface 503. The diameter of the ball 6 is larger than the aperture of the positioning circular hole. Under the action of the first spring 4, the annular boss portion 501 presses the ball 6 into the positioning circular hole, and the ball 6 protrudes to the inner side of the positioning circular hole, which is used to clamp the clamping table set at the bottom of the shell of the crystal lamp physiotherapy device 15.

[0029] like Figure 4 and Figure 7As shown, an annular groove 101 is provided on the outer wall of the upper end of the bottom shell 1, and a snap ring 7 is provided in the annular groove 101.

[0031] The working principle of the utility model is as follows: first, the utility model is fixed on a plane in the car. When charging the crystal lamp therapy device 15, the crystal lamp therapy device 15 is placed in the bottom shell 1 and connected to the charging plug 3. The charging line and the adapter are connected to the charging socket 12. The adapter is then connected to an external power source to charge the crystal lamp therapy device 15. The charging state is as follows: Figure 6 When the crystal lamp therapy device 15 is charged, under the action of the first spring 4, the annular boss portion 501 presses the ball 6 into the positioning circular hole, and the ball 6 protrudes to the inner side of the positioning circular hole, and clamps the clamping table set at the bottom of the crystal lamp therapy device 15 shell, so that the crystal lamp therapy device 15 can be firmly locked. The locked state is shown in FIG. Figure 6 At the same time, under the action of the second spring 10, the annular movable platform 9 presses the bottom of the shell of the crystal lamp therapy device 15, so that the crystal lamp therapy device 15 is placed more firmly in the bottom shell 1. After the crystal lamp therapy device 15 is charged, the movable shell 5 is pushed downward, as shown in FIG. Figure 7 As shown, the ball 6 can be separated from the positioning circular hole and the card table set at the bottom of the crystal lamp therapy device 15 shell, and rolled along the connecting inclined surface 503 to the annular groove 502. At this time, the crystal lamp therapy device 15 can be easily removed, which is very convenient to use.

[0032] To sum up, when the utility model is used to charge the crystal lamp therapy device 15, under the action of the first spring 4, the annular boss portion 501 presses the ball 6 into the positioning circular hole, and the ball 6 protrudes to the inner side of the positioning circular hole, clamping the clamping platform set at the bottom of the shell of the crystal lamp therapy device 15, so that the crystal lamp therapy device 15 can be firmly locked, and even if the crystal lamp therapy device 15 is charged in a shaking car, there will be no problem of poor contact and unstable charging.
