A third gear 12 is fixedly arranged at one end of the transmission shaft of the second forward and reverse motor 11, and the second gear 10 and the third gear 12 are meshed with each other.

[0024] As a further implementation scheme of the above technical scheme: a first fixing seat 13 is fixedly provided inside the support rod 1, and one side of the first fixing seat 13 is fixedly connected to the side of the first forward and reverse motor 2, so that the first fixing seat 13 is convenient for fixing the first forward and reverse motor 2.
