1. A damping integrated device, comprising:
a base body, which has a predetermined length and includes an inner cavity extending along a lengthwise direction thereof;
a frequency adjustment component disposed in the inner cavity WO, the frequency adjustment component comprising an elastic member and an connecting member, with one end of the elastic member in the lengthwise direction being connected to the base body, and the other end thereof being connected to the connecting member;
a first connector extending into the inner cavity and at least partially protruding out of the base body in the lengthwise direction, the first connector being connected to the connecting member and capable of moving relative to the base body, so as to make the elastic member stretch or shrink in the lengthwise direction; and
a damping component disposed in the inner cavity, the damping component being connected to the connecting member and at least partially abutting against an inner wall of the base body, and the damping component being configured to absorb kinetic energy of the first connector.
