Connecting rod may be implemented in this way while driving the first auxiliary switch output shaft and the rotation of the second auxiliary switch output shaft, it is possible to reduce zero
Component composition, so that the configuration of the present invention is simple；
3, the first connecting plate of the invention, the second connecting plate and articulated shaft setting are as follows: when the connecting rod drives the first connecting plate and second to connect
Plate turns to articulated shaft and contradicts strip hole when closing on one end of the second auxiliary switch output shaft, and the first connecting plate and the second connecting plate are mutual
Alignment；In this way when connecting rod the first connecting plate of drive and the second connecting plate turn to the first connecting plate and the second connecting plate is mutually aligned, connecting rod
It can continue to drive the first connecting plate and the rotation of the second connecting plate, without blocking；
4, the first connecting plate of the invention, the second connecting plate and articulated shaft setting are as follows: when the connecting rod drives the first connecting plate and second to connect
When plate turns to the one end of articulated shaft conflict strip hole far from the second auxiliary switch output shaft, jointed shaft center is opened to the first auxiliary
Close distance and jointed shaft center being equidistant to the second auxiliary switch output axis center of output axis center；Setting can be in this way
When so that connecting rod driving the first connecting plate and the second connecting plate to rotate, the first connecting plate and the second connecting plate rotational angle are identical, ensure that the
The synchronism of one auxiliary switch and the movement of the second auxiliary switch.
