The utility model discloses a
keel cutting bifurcation
knife switch which comprises a base, a sliding
cutting mechanism, a rotary bifurcation mechanism and a
handle, the base is provided with a support and a blade support, the sliding
cutting mechanism comprises a sliding plate and two blades, the rotary bifurcation mechanism comprises two expansion pieces, two transmission pieces and a connecting piece, the sliding plate is connected with a pressing plate, and the pressing plate is connected with the
handle. The support is provided with a
keel baffle, when the two expansion pieces are in the storage state, the front end of the pressing plate extends out of the front side position of the front end face of the
keel baffle, and when the two expansion pieces are in the forked state, the front end of the pressing plate retracts back to the rear side position of the front end face of the keel baffle. According to the keel cutting and forking
knife switch, cutting and forking
machining of a keel can be met, the pressing plate is arranged to fix the upper face of the keel, deformation and displacement of the keel can be prevented when the keel is
cut, the cutting effect is guaranteed, after keel forking
machining is completed, the pressing plate can be automatically staggered from the upper face of the keel, and the pressing plate is automatically staggered from the upper face of the keel. The dismounting operation of the keel cannot be interfered, and the operation is very convenient.
