In this embodiment, one end of the oscillating bar 754 is a rotation connection end for rotation fixation, and the other end is an extension end extending freely, and the extension direction of the free end of the oscillating bar 754 forms an included angle with the first guide rail 711 and the second guide rail 721. In the present embodiment, the third mass 751 is disposed on the oscillating bar 754, and is slidably connected to the oscillating bar 754.
Through the arrangement, the swing rod 754 is arranged, so that the stable operation of the third mass block 751 is effectively ensured, the invalid swing of the third mass block is favorably inhibited, and the energy recovery efficiency of the utility model is favorably improved. Furthermore, when the third mass experiences a stronger vibration in one direction, the swinging of the pendulum lever 754 is more favorable for guiding the third mass in the direction in which the vibration is perceived, so that the energy collection efficiency is higher.
As shown in fig. 1, according to another embodiment of the present invention, the rotation connection end of the swing link 754 is provided with a fifth elastic restoring member.
