A plurality of first openings 22 are opened on the first curved surface 20 and the second curved surface 21, and a pressure sensor 23 is fixedly installed in the first opening 22 of the second curved surface 21. A limiting component is provided on the second shell 12, and the limiting component is used to limit the angle at which the first curved surface 20 and the second curved surface 21 fit together.

[0023] A first separation membrane 27 is fixedly connected to the first cavity 18, one end of the first separation membrane 27 is fixedly connected to the first curved surface 20, and the other end of the first separation membrane 27 is fixedly connected to the sliding push plate 13. A second separation membrane 28 is fixedly connected to the second cavity 19, one end of the second separation membrane 28 is fixedly connected to a side wall of the second cavity 19, and the other end of the second separation membrane 28 is fixedly connected to the second curved surface 21. The first separation membrane 27 divides the first cavity 18 into two cavities, one cavity is filled with water, and the other cavity is filled with oil.

[0024] It is worth noting that the first separation membrane 27 and the second separation membrane 28 are both flexible waterproof and oil-proof films. The second separation membrane 28 divides the second cavity 19 into two cavities, one cavity receives water and the other cavity receives oil. The first separation membrane 27 and the second separation membrane 28 are in the same plane in the vertical direction.

[0025] A first slot 24 is defined in the first curved surface 20 , in which a permanent magnet 25 is fixedly disposed. An electromagnet 26 is fixedly disposed on a side wall of the second cavity 19 . It is worth noting that both the permanent magnet 25 and the electromagnet 26 are of the prior art.

[0026] The limiting assembly includes an elastic member 32 and a slider 33. A second slot 30 is provided at the edge of the first curved surface 20, and a third slot 31 is provided at the edge of the second curved surface 21. One end of the elastic member 32 is fixedly connected to the third slot 31, and the other end of the elastic member 32 is fixedly connected to the slider 33. The slider 33 is slidably connected to the second slot 30.

[0027] A limiting plate 14 is fixedly connected to the end face of the first shell 11 away from the second shell 12, and an electric push rod 15 is fixedly connected to the limiting plate 14.
