[0036] The transmission assembly includes an arc groove 522 and a push block 523. The second gear 513 is provided with a plurality of through arc grooves 522 at equal intervals in a circular array. A push block 523 is slidably inserted in each arc groove 522. The plurality of push blocks 523 are perpendicular to the right side surface of the rotating table 41. The different positions of the push blocks 523 in the arc groove 522 have different distances from the rotation center of the second gear 513.
