[0030] Working principle: when in use, the power supply and PLC controller can be turned on to control the electrical appliances. The prior art will not be described here.

The rotating shaft 23 pushes the second support plate 7 to move to the left side through the cooperation of the two eccentric wheels 24 and the two arc grooves 25, the first reduction mechanism is separated from the driving gear 3 and the passive gear 5, the first right bevel gear 19 and the second right bevel gear 22 are meshed with the driving gear 3 and the passive gear 5, and the transmission shaft 4 is decelerated by the second reduction mechanism. By observing the accompanying drawings, it can be seen that the diameter of the second right gear 21 on the second support plate 7 is larger than the second left gear 15 on the first support plate 6, and the diameter of the second right bevel gear 22 is smaller than the diameter of the second left bevel gear 16, so that the deceleration effect of the second reduction mechanism is better than that of the first reduction mechanism. The rotation of the eccentric wheel 24 cooperates with the arc groove 25 to drive the second support plate 7 to move horizontally left and right, thereby realizing the switching of the use of the first reduction mechanism and the second reduction mechanism.

[0031] Embodiment 2

[0032] The difference between Example 2 and Example 1 is that the square rod 31, the tension spring 30 and the positioning rod 28 are removed and replaced with bolts, and the bolts are threadedly connected to the outside of the crank 26. After the crank 26 is rotated, the bolts are tightened to contact the outside of the reduction box 1, thereby improving the stability of the crank 26. This application includes all structural shapes, sizes and materials of Example 1, and they can be selected and adjusted to meet specific usage conditions. The accompanying drawings are all schematic structural diagrams, and the specific actual sizes can be appropriately adjusted.
