Namely, the rack plate comprises an upper plate 801, a lower plate 802 and a fixed middle plate 805, the fixed middle plate is positioned between the upper plate and the lower plate, the guide groove 7 is arranged between the upper plate and the lower plate, electric telescopic rods 804 are arranged at the upper end and the lower end of the rack plate, bases of the electric telescopic rods are fixed on the upper plate and/or the lower plate, output ends of the electric telescopic rods are fixedly connected with the fixed middle plate, and racks 803 are fixed on the fixed middle plate, so that the electric telescopic rods drive the racks to move. Namely, when the rack of the rack plate is required to be meshed with the left half gear, the electric telescopic rod pushes the rack to move outwards (leftwards in fig. 10) to a preset position, so that the teeth of the rack plate and the teeth of the left half gear can be meshed for transmission; when the rack of the rack plate is not needed to be meshed with the left half gear, the electric telescopic rod retracts to drive the rack of the rack plate to move inwards to a preset position, so that the teeth of the rack plate cannot be meshed with the teeth of the left half gear.
The structure and principle of the racks of the movable plate are similar to those of the rack plate, and the difference is that the racks of the movable plate and the racks of the rack plate face opposite directions, namely when the racks of the movable plate are needed to be meshed with the right half gear, the electric telescopic rod pushes the racks to move outwards (rightward in fig. 10) to a preset position, so that the teeth of the racks of the movable plate and the teeth of the right half gear can be meshed for transmission; when the racks of the movable plate are not needed to be meshed with the right half gear, the electric telescopic rod is retracted to drive the racks of the movable plate to move inwards to a preset position, so that the teeth of the racks of the movable plate cannot be meshed with the teeth of the right half gear.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
