The three-position operating mechanism as claimed in claim 1, wherein the guiding structure comprises at least two guiding bolts fixed on the mounting plate at intervals along the reciprocating direction of the driving plate, sleeves capable of rotating relative to the guiding bolts are sleeved on the guiding bolts, the guiding matching structure is a long hole formed in the driving plate, and the sleeves are arranged in the long hole in a penetrating mode.
3. The three-position operating mechanism as claimed in claim 2, wherein the guide bolt is further sleeved with a washer, the diameter of the washer is larger than the width of the long hole, and the washer is used for being matched with the side face of the driving plate in a stop mode so as to prevent the driving plate from falling off.
4. A three-position operating mechanism according to claim 2 or claim 3 wherein the mounting plate includes a spacer secured to the mounting plate, the guide bolt being secured to the spacer, the spacer being located between the drive plate and the mounting plate.
5. The three-position operating mechanism according to any one of claims 1 to 3, wherein the mounting plate comprises a first mounting plate and a second mounting plate which are arranged at intervals, the first mounting plate is used for being fixedly connected with the three-position switch, the gear transmission structure is located between the first mounting plate and the second mounting plate, two ends of the mechanism input shaft and two ends of the mechanism output shaft are respectively rotatably assembled on the first mounting plate and the second mounting plate, a fixing column for limiting the interval between the two plates is further arranged between the first mounting plate and the second mounting plate, a part of the driving plate is in an I-shaped structure, and a concave part of the I-shaped structure is used for avoiding the fixing column.
6. The three-position operating mechanism according to any one of claims 1 to 3, wherein the first auxiliary switch and the second auxiliary switch are fixed to an upper end of the mounting plate, and the drive plate is located above the mechanism output shaft.
