At this time, since the switching rocker arm 22 and the switching rotary buckle 7 both rotate, the switching spring 6 between them is not pushed up, and thus the switching spring 6 is not further compressed, so that the spring potential energy required to be overcome by the energy storage spring 15 is relatively small, and the energy storage spring 15 does not need to be made as large as the existing product, thereby being beneficial to realizing light weight of the product.

The embodiment is provided with an energy storage spring support 16 for supporting the energy storage spring 15, two sides of the energy storage spring support body are respectively provided with a folded edge, and the bottom of the energy storage spring support is bent and formed into two legs, so that the energy storage spring support is conveniently fixedly inserted into the corresponding assembly grooves of the base 122 for fixing. When the energy is not stored, two feet of the energy storage spring 15 are respectively positioned at two sides of the folded edge of the energy storage spring support body; after the energy storage starts, one leg of the energy storage spring 15 abuts against one of the folded edges, and the other leg abuts against a spring pushing surface 174a of an energy storage spring pushing block 174 on the energy storage rocker arm 17, so that the energy storage spring 15 is compressed to store energy; when the energy storage rocker arm 17 reaches the preset locking position, the energy storage rocker arm 17 is locked by the energy storage lock assembly 133.

As shown in fig. 4-5, the energy storage rocker arm body 170 of the energy storage rocker arm 17 is provided with an energy storage rocker arm shaft hole 171, the inner wall of the energy storage rocker arm body is provided with a fan-shaped energy storage operating element groove 172, the spindle 19 is installed in the energy storage rocker arm shaft hole 171, the energy storage operating element 20 is specifically a connecting pin which is connected with the spindle 19 and at least partially accommodated in the energy storage operating element groove 172, and an angle gap exists between the side wall of the groove and the energy storage operating element 20. The charging rocker arm 17 is rotatable within a certain range relative to the main shaft 19 due to the angular clearance between the charging operating member 20 and the side wall of the charging operating member slot 172.

A fan-shaped turn-buckle tail block groove 177 is formed in the bottom of the energy storage rocker arm 17, the turn-buckle tail block 73 at the top of the turn-buckle 7 can be placed in a gap, an angle gap exists between the two, therefore, the association of the energy storage rocker arm 17 and the turn-buckle 7 is realized, the energy storage rocker arm 17 can only touch the turn-buckle 7 in the energy storage release process, and the energy storage rocker arm 17 can drive the turn-buckle 7 to rotate within a certain angle range. Here, the fastening tail block groove side 177a is not in contact with the opening/closing turn-fastening tail block 73 in any state, and the fastening tail block groove side 177b can be in contact with the opening/closing turn-fastening tail block 73 only in the stored energy releasing process. In the energy storage releasing process, the energy storage rocker arm 17 rotates reversely, and the buckling tail block groove side face 177b pushes against the opening and closing rotary buckling tail block side face 73b to drive the opening and closing rotary buckle 7 to rotate reversely. During the energy storage locking, the energy storage rocker arm 17 is fixed by the locking, because there is the angle clearance in deciliter spinner tail block 73 and spinner tail block groove 173 for deciliter spinner 7 can be driven by deciliter rocker arm 22 and rotate.
