1. A multi-stage synchronous driving mechanism, comprising:
a housing;
a motor, disposed on the housing;
a gear transmission component, driven and connected to the motor; and
a multi-stage execution component, comprising a support, a sun gear, a plurality of planetary gears, and a plurality of execution units, wherein the support is disposed on the housing, the sun gear and each of the planetary gears are rotatably disposed on the support, respectively, each of the execution units is connected to each of the planetary gears in a one-to-one correspondence, the sun gear is driven and connected to the gear transmission component, and each of the planetary gears is engaged with the sun gear, respectively; wherein
the motor drives the sun gear to rotate by using the gear transmission component, so that the sun gear drives each of the planet gears to rotate, thereby driving each of the execution units to rotate relative to the housing;
wherein each of the execution units comprises an insertion post, a stop plate, and a free arm that are connected in sequence, the planetary gear is sleeved on the insertion post, the free arm is penetrated in the support, and the stop plate movably abuts against the support;
wherein the execution unit further comprises a stop post, a stop slot is disposed on the planetary gear, the stop post is disposed between the insertion post and the stop plate, and the stop slot is adapted to the stop post.
