[0065] The piston component 704 is a block structure, and its material is selected according to actual needs. The piston component 704 is arranged in the sliding cavity 703, and is slidably connected to the inner wall of the sliding cavity 703. A third annular groove 7041 is provided on it, and an overflow channel 7042 is provided inside the piston component 704; the piston component 704 can move longitudinally in the sliding cavity 703 and is restricted by the limiting assembly.

[0066] It should be noted that the width of the third annular groove 7041 is greater than the widths of the first annular groove 7011 and the second annular groove 7021, and greater than the distance between the first annular groove 7011 and the second annular groove 7021;

[0067] The limiting cavity 707 is disposed at the bottom of the sliding cavity 703 and is interconnected with the sliding cavity 703;

[0068] A circuit-breaking passage 705 is also provided inside the main body, one end of the circuit-breaking passage 705 is connected to the entry end 701, and the other end is connected to the limit cavity 707;

[0069] The circuit breaker channel 705 is further provided with an interruption component 706;

[0070] The lifting component 708 is a block-shaped structure, and the lifting component 708 is disposed in the limiting cavity 707, and is slidably connected to the inner wall of the limiting cavity 707, and there is a gap between the bottom of the lifting component 708 and the bottom of the limiting cavity 707;

[0071] The elastic component 710 is a spring, which is disposed in the limiting groove, with one end of the elastic component 710 fixedly connected to the inner wall of the limiting groove and the other end of the elastic component 710 fixedly connected to the piston component 704 .

[0072] It should be noted that the interruption component 706 is a combined structure, including:

[0074] The sensing component is electrically connected to the valve component by signal. The sensing component is located above the valve component and passes through the main body. The valve component is opened or closed by the sensing component, thereby opening or closing the circuit-breaking channel 705.

[0075] Through the above technical solution, the technical effects produced in the embodiments of the present application are:

[0076] Under normal conditions, the interruption component 706 is in an open state, that is, the sensing component is started (the sensing card contacts the sensing component), the valve component is opened, the circuit-breaking channel 705 is opened, and a part of the external pressure medium enters the circuit-breaking channel 705, causing the lifting component 708 to rise, thereby causing the piston component 704 to rise. In the initial state, the first annular groove 7011 and the third annular groove 7041 are aligned with each other, and the external pressure medium can only enter the first annular groove 7011 and the third annular groove 7041. When the piston component 704 rises (limited by the limiting component to avoid excessive rise), the third annular groove 7041 is aligned with the second annular groove 7021 and overlaps with the first annular groove 7011. The external pressure medium enters the annular channel formed by the second annular groove 7021 and the second annular groove 7021 through the first annular groove 7011, and flows out from the output end 702 to supply pressure to the energy storage component. At this time, the elastic component 710 is compressed, and the excess external pressure medium is discharged from the leakage channel 709 through the overflow channel 7042. When interruption is required, the sensing component closes the valve component to cut off the circuit-breaking channel 705, and the lifting component 708 is reset under the action of its own gravity, the gravity of the piston component 704, and the elastic force of the elastic component 710, so that the third annular groove 7041 is disengaged from the second annular groove 7021, and then the first annular groove 7011 is aligned with the third annular groove 7041, and the external pressure medium cannot flow out from the output end 702, and the external pressure medium in the limiting cavity 707 enters the leakage channel 709 from the overflow channel 7042.

[0077] By adopting a mechanical hydraulic structure, not only is the operation more convenient, but it can also provide a stable pressure output for the energy storage component, making the overall operation more stable.
