the mounting plate 8 is also movably provided with a contactor 21 matched with the pulley 12 on the connecting plate 11, and one end of the contactor 21 matched with the pulley 12 is obliquely arranged;
the energy storage mechanism is arranged on the mounting plate 8 and is connected with the contactor 21;
the energy storage mechanism comprises a meshing structure arranged on the mounting plate 8 and an elastic component which is connected with the meshing structure and movably arranged through the mounting plate 8;
the elastic component is connected with the adjusting component;
