Description
Technical field
The present invention relates to a kind of cutting means, relate in particular to a kind of cutting means with protector of pivot.
Background technology
Tradition is used for cutting paper or is used for the cutting means that bound book uses, and mainly comprises the cut-off knife that a platform and that can be used for placing paper is hubbed at platform.During paper cutting, need to push the paper location with a hand, a hand operated cut-off knife is accomplished and is cut.Being used for existing cutting means does not have protector, may injure the finger of pushing paper because of carelessness, or point and run into cut-off knife because of carelessness, can scratch finger yet.
Summary of the invention
The purpose of this invention is to provide a kind of cutting means, injure finger when preventing to cut, or run into cut-off knife because of carelessness and scratch finger with protector of pivot.
The present invention realizes that the technical scheme of above-mentioned purpose does; A kind of cutting means with protector of pivot; Comprise cutting platform and being located at the said cut-off knife that cuts platform that on said cut-off knife, be provided with protector, this protector comprises the protective plate A that is located at cut-off knife one side with pivot; This protective plate A is hubbed on the pivot of cut-off knife, and this protective plate A bottom protrudes in the cutting edge of said cut-off knife.
Further; Also be provided with resetting means between protective plate A and the cut-off knife; Said resetting means comprises pilot pin and the back-moving spring that is arranged at cut-off knife one side, and said protective plate A bottom is provided with the protection base, and said protective plate A top is provided with the rib that can block the cut-off knife top; Said back-moving spring is arranged between pilot pin and the protection base, and said pilot pin is arranged in the guide groove of said protective plate A.
Further, be arranged with pilot pin spring storage tank on the said pilot pin, said protection base is provided with protective plate spring storage tank, and the two ends up and down of above-mentioned back-moving spring place respectively in said pilot pin spring storage tank and the protective plate spring storage tank.
Further, also be provided with a protective plate B at said cut-off knife opposite side, this protective plate B top is connected with protective plate A, and the base of protective plate B protrudes in the cutting edge of cut-off knife.
Beneficial effect of the present invention is owing to be provided with protector in the cut-off knife one or both sides, can avoid damaging the user.The paper that will cut is pushed down on the feasible protection of the effect of back-moving spring base necessarily precompression; If finger misplaces in this zone simultaneously; The precompression on protection base also can let the user in time will point extraction; Thereby can avoid damaging the user, the cut-off knife opposite side is provided with protective plate B in addition, can avoid running into because of carelessness the cut-off knife cutting edge.

The specific embodiment
Like Fig. 1,2, shown in 3; This has the cutting means of the protector of pivot; Comprise cutting platform 4 and being located at this cut-off knife that cuts platform 41 that on cut-off knife 1, be provided with protector, this protector comprises the protective plate A 2 that is located at cut-off knife 1 one sides with pivot 3; This protective plate A 2 is hubbed on the pivot 3 of cut-off knife 1, and this protective plate A 2 bottoms protrude in the cutting edge of cut-off knife 1.Between protective plate A 2 and cut-off knife 1, be provided with resetting means.As shown in Figure 4; Resetting means comprises the pilot pin 5 and back-moving spring 6 that is arranged at cut-off knife 1 one sides; Protective plate A 2 bottoms are provided with protection base 22; Protective plate A 2 tops are provided with the rib 21 that can block the cut-off knife top, and back-moving spring 6 is arranged between pilot pin 5 and the protection base 22, and pilot pin 5 is arranged in the guide groove 23 of protective plate A 2.Be arranged with pilot pin spring storage tank 7 on the pilot pin 5, after pilot pin 5 passed pilot pin spring storage tank 7, the end positioned with shaft end ring 9.Protection base 22 is provided with protective plate spring storage tank 8, and the two ends up and down of above-mentioned back-moving spring 6 place respectively in pilot pin spring storage tank 7 and the protective plate spring storage tank 8.Pilot pin 5 can move along guide groove 23, and pilot pin spring storage tank 7 can move with pilot pin 5, thereby can realize cutting operation.
Among another embodiment like Fig. 5, also be provided with a protective plate B 10 at cut-off knife 1 opposite side, this protective plate B 10 tops are connected with protective plate A2, and the base of protective plate B 10 protrudes in the cutting edge of cut-off knife.Protective plate B 10 can be one-body molded with protective plate A2, and the two top also can link together through bonding or connector.
Operation principle of the present invention is when cut-off knife 1 cuts paper, to hold the cut-off knife handle and push downwards; Protector rotates around pivot 3 with one of cut-off knife, moves downward, and touches on the protection base 22 of the protective plate A 2 of protector when cutting platform 4; The protective plate A and the protective plate B of protector no longer move, and cut-off knife 1 continues motion, drive pilot pin 5 and move along guide groove 23; Compression reseting spring 6; Cut-off knife 1 protector relatively continues to press down, thereby the cutting edge of cut-off knife 1 can protrude in protection base 22, accomplishes cutting function.Thereby the present invention can place the user and comes to harm.
