Novel knife rest position transmitting device

The invention relates to a novel knife rest position transmitting device. The device comprises a sensing module connected with a knife rest main body and a module which is to be measured and connected with a knife rest main axle, wherein the sensing module comprises a first proximity switch, a second proximity switch and a third proximity switch respectively, the module to be measured comprises a transmitting ring which is mounted corresponding to the sensing module, a first convex block, a second convex block, a third convex block and a fourth convex block are sequentially arranged on the transmitting ring; the horizontal distance between the sensing ends of the first proximity switch, the second proximity switch and the third proximity switch and the axle of the transmitting ring is equal, and when a knife rest is arranged at different positions, and different combinations of the proximity switches in the sensing module can sense different convex blocks on the transmitting ring. By adopting the above structure, the space structure of the knife rest itself is utilized to determine and transmit the position, and moreover the transmitting device is simple to control and convenient to adjust.
