The energy storage mechanism is composed of an energy storage spring 2 and an energy storage buckle 3, two ends of the energy storage spring 2 can respectively exert force on the shell and the energy storage buckle 3, and the energy storage spring 2 is stretched to store energy by rotating the energy storage buckle 3; on the contrary, the energy storage spring 2 pushes the energy storage buckle 3 to rotate reversely when the energy is released. Here, the energy-storing buckle 3 is provided with an energy-storing buckle supporting plate 14, and the two buckles are buckled together to keep the stability of the energy-storing buckle 3.

The on-off button 4, the on-off spring 5 and the on-off button 6 constitute an on-off mechanism, wherein the on-off button 4 and the on-off button 6 are integrally fastened, a moving contact (not shown) in an external contact pole 200 of the on-off button 6 is connected, and the on-off spring 5 exerts force on the on-off button 4 and the on-off button 6. After energy is stored, the opening and closing spring 5 can be stretched after the opening and closing upper buckle 4 is rotated, and then the opening and closing lower buckle 6 is driven to rotate clockwise so as to carry out closing operation; when releasing energy, the energy storage buckle 3 rotates reversely to drive the opening upper buckle 4 and the opening lower buckle 6 to rotate reversely so as to perform opening operation.

The energy storage spring 2 is sleeved on a central column around the spindle hole 170 on the bottom wall of the top cover, and the bottom wall of the top cover 17 is further provided with an energy storage spring groove 171, so that the energy storage spring 2 is arranged on the top cover 17. Energy storage is detained 3 and is located energy storage spring 2 below, and the main shaft hole 30 suit of energy storage knot 3 is in main shaft 1, and energy storage is detained 3 bottom surfaces and is set up two energy storage and detain driving block 31, and energy storage round pin 20 passes main shaft 1 back, and the both ends of energy storage round pin 20 can butt corresponding energy storage respectively and detain driving block 31, and energy storage is detained 3 and is located main shaft 1 like this to can make energy storage detain 3 can link with main shaft 1.

When the energy storage buckle 3 rotates clockwise, the energy storage buckle spring pushing block 35 stretches the energy storage spring 2 to store energy. When the stored energy is released, the stored energy spring 2 pushes the stored energy buckle 3 to rotate reversely. When the stored energy is released, the stored energy buckle 3 rapidly rotates anticlockwise due to the large force of the stored energy spring 2, and needs to stop acting in time after the brake separating action is completed so as to avoid excessive brake separating, so that the top cover 17 and the stored energy buckle 3 are provided with corresponding matching characteristics, specifically, the top cover is provided with the stored energy buckle limiting block 172, and the other side surface 35b of the spring push block of the stored energy buckle is a limiting surface, so that the reverse rotation angle of the stored energy buckle 3 is limited.
