Abstract

The utility model relates to a knife rest device with a fine tuning mechanism, comprising a fixing seat, a deflection seat, a tool bit, a rotating shaft and a fine turning mechanism. The deflection seat is arranged under the fixing seat; the tool bit is arranged on the deflection seat; the rotating shaft is connected between the fixing seat and the deflection seat; and the rotating shaft makes the tool bit do deflection opposite to the fixing seat. The fine tuning mechanism comprises a slotted hole, a locating hole, a locating shaft and a fine tuning block. The slotted hole is arranged on the fixing seat; the locating hole is arranged on the deflection seat and corresponds to the slotted hole; one end of the locating shaft passes and is fixed in the locating hole and the other end passes the slotted hole; a clearance is formed between the locating shaft and the slotted hole; and the fine tuning block is connected with the fixing seat and butts against the outer peripheral edges of the locating shaft. When the fine tuning block is moved, the locating shaft is driven to move in the slotted hole at the same time and then the deflection seat does angle deflection around the rotating shaft. The end plane of the tool bit intersects with the side blade face of a knife ring and cuts in a point contact way. The cutting resistance is reduced; the cutting capability is improved; the service life is prolonged; and the end plane is kept flat after the cutting.
