[0055] The working principle of the invention of this embodiment:

[0056] In the first adjustment mode, when it is necessary to transfer the gravity on the second base of the tumbler to the first base, turn the handle clockwise, the handle drives the clamping column to rotate in the second slot, the first clamping block is clamped in the first clamping slot, and the second clamping block is separated from the second clamping slot. The handle can directly drive the first winding shaft to rotate and wind the tape by driving the turntable to rotate, and the tape on the second winding shaft is automatically released under the pull of the first winding shaft. When the second winding shaft rotates to release the tape, it drives the fourth synchronous wheel to rotate, and the rotation of the fourth synchronous wheel indirectly drives the first synchronous wheel to rotate, thereby realizing the transfer of gravity on the second base to the first base.

[0057] In the second adjustment mode, when it is necessary to transfer the gravity on the first base of the tumbler to the second base, turn the handle counterclockwise, and the handle drives the clamping column to rotate in the second slot body. When the clamping column rotates to the connecting slot in the second slot body, it slides down into the first slot body under the guidance of the first guide plate and the second guide plate and slides in the first slot body. During this process, the clamping column drives the slide seat to slide upward, and the second clamping block is clamped into the second clamping slot of the first synchronous wheel. The first clamping block is separated from the first clamping slot, and the handle directly drives the first synchronous wheel to rotate, and then the first synchronous wheel drives the fourth synchronous wheel to rotate, so that the fourth synchronous wheel drives the second winding shaft to rotate to realize active winding of the tape, and the tape on the second winding shaft is automatically released under pulling, so as to realize the transfer of gravity on the first base to the second base.

[0058] When it is necessary to transfer the gravity on the second base of the tumbler to the first base again, turn the handle clockwise. When the card column rotates clockwise in the second slot body to the connecting slot, it returns to the second slot body under the guidance of the first guide plate and the second guide plate and continues to rotate in the second slot body. During this process, the slide seat slides downward, the first card block is inserted into the first card slot, and the second card block is separated from the second card slot, switching to the first adjustment mode.
