The arrangement of the structure enables the first elastic element 6 to store energy in the process that the linear driving part 2 drives the transmission part 3 to move forwards along the X direction, and after the linear driving part 2 cancels the driving force to the transmission part 3, the first elastic element 6 can release energy, so that the transmission part 3 drives the first execution part 4 to return.

With the above structure, when the linear driving part 2 drives the transmission part 3 to move in the positive direction X, the second actuating part 5 is away from the transmission block to store energy, and after the linear driving part 2 cancels the driving force to the transmission part 3, the second elastic element 7 releases energy and resets the second actuating part 5.
