The specific embodiment
Referring to Fig. 1, Fig. 2, the two-way locked type cutting knife of cutter head of the present utility model, the cutter head 4 that comprises left cutter hub 1, right cutter hub 2, is clipped in knife rest 3 in the middle of the left and right sides cutter hub, is inlaid on the knife rest and can slides along knife rest, and two-way locking release mechanism 5 of cutter head and the bidirectionally limited mechanism 6 of cutter head.The two-way locking release mechanism 5 of cutter head is arranged between left cutter hub 1 and the knife rest 3 state of returning sword of cutter head and goes out the cutter state implements two-way locking or release; The rear portion that the bidirectionally limited mechanism 6 of cutter head is connected cutter head 4 is implemented bidirectionally limited to returning sword and going out cutter of cutter head.
Cooperation is referring to Fig. 3, the two-way locking release mechanism 5 of cutter head in the utility model comprises two-way securing rod 51 of cutter head and torsion spring 52, the front end of the two-way securing rod 51 of cutter head is provided with toggle 511, the centre is provided with first gag lever post 512 that protrudes upward, the rear end is provided with second gag lever post 513 that stretches out downwards, be provided with minor axis 514 between first gag lever post and second gag lever post, the two-way securing rod 51 of cutter head is by minor axis 514 and left cutter hub 1 and 3 rotatable linking to each other of knife rest.On knife rest 3, be provided with first projection 31 and second projection 32, the intermediate sleeve of torsion spring 52 is contained on first projection 31 of knife rest, a free end of torsion spring is pressed on second gag lever post of the two-way securing rod of cutter head 513, and another free end is pressed on second projection 32 of knife rest.Be provided with toggle hole 11 on left cutter hub 1, the toggle 511 of the two-way securing rod of cutter head exposes from this toggle hole.
