10. The multi-pole load disconnector according to claim 9, characterized in that: The energy storage turntable (240) is provided with an unlocking block (248). The output turntable (250) includes a second turntable body (252). An output shaft (251) is formed by a protrusion at the center of one side of the second turntable body (252). A one-way locking block (253) is formed by a protrusion near the outer periphery on the side of the second turntable body (252) where the output shaft (251) is located. A first locking surface (2531) is formed on one side of the one-way locking block (253), and a first guide surface (2532) is formed on the other side. An arc-shaped through groove (254) is provided on the second turntable body (252). The unlocking block (248) of the energy storage turntable (240) cooperates with the arc-shaped through groove (254) to enable the energy storage turntable (240) to... When the energy storage turntable (240) is closed, it rotates synchronously with the output turntable (250). When the energy storage turntable (240) is open, the unlocking block (248) can move to the other end in the arc-shaped through groove (254) so ​​that the energy storage turntable (240) can rotate relative to the output turntable (250) at a certain angle to form a one-way linkage. The elastic positioning element (290) has a protruding elastic locking block (291). The elastic locking block (291) has a second locking surface (292) and a second guide surface (293). The unlocking block (248) of the energy storage turntable (240) and the second guide surface (293) of the elastic locking block (291) cooperate to release the locking effect of the elastic positioning element (290) on the output turntable (250).
