Blade locking linkage unit, in the present embodiment, this assembly comprises a rod-like members and the second flexible member, specifically rod-like members is rear bar 4 in the present embodiment, rear bar 4 is divided into thick section 41 and thin segment 42, and thick section 41 is to there being a transition boss 43 between thin segment 42, and the part that wherein thin segment 42 is positioned at end is provided with screw thread 421, this screw thread 421 coordinates with the screwed hole 25 of knife rest 2 rear ends, thereby rear bar 4 is fixed on to knife rest 2 rear ends; Above, knife rest 2 is thread connecting mode with rear bar 4, and in addition, the present invention also can use any suitable fixed form to connect knife rest 2 and rear bar 4, be these both interconnect and in use relative position fix, the present invention is not limited only to above-mentioned detailed description of the invention;
In the present embodiment, the second flexible member is spring 5, and this spring 5 is set in the taper end 42 of rear bar 4, it comprises first end 51 and the second end 52, first end 51 is connected in rear bar 4, is specially on the transition boss 43 that withstands on rear bar 4, and the second end 52 is connected in the cavity inner wall of following knife bar 6.Except spring, the second flexible member can also select any suitable flexible members such as shell fragment to reach identical object;
Knife bar 6, knife bar 6 is provided with a cavity 61, and above-mentioned knife rest 2, reed 3, rear bar 4, spring 5 are all arranged in cavity 61, and wherein thick section of rear bar 4 comprises that one protrudes from the press section 44 outside the cavity 61 of knife bar 6, referring to Fig. 5 and Fig. 6; Especially, referring to Fig. 4, in cavity 61, be provided with the round platform 62 of protrusion, be used for limiting spring 5, now, the first end 51 of spring 5 withstands on the taper end 42 of rear bar 4 to the transition boss 43 of butt end 41, and the second end 52 withstands on the projecting inward round platform 62 of the cavity 61 of above-mentioned knife bar 6, except adopting the contact connected mode on top, also can adopt and be fixed together or buckle connected mode together; In addition, the front portion of knife bar 6 internal cavities 61 is provided with a guide table, be bucking ladder 63 in the present embodiment, be used for accommodating reed 3 and guide its distortion, kink 321 with movable contact spring 3 when knife rest 2 moves forward or backward along bucking ladder 63 backward or move forward, thereby make the inserted sheet 322 of reed 3 insert or exit the fixing hole 11 of blade 1.Conventionally the transition boss 43 in round platform 62 and rear bar 4 is set to circle, but their shape also can adopt other any shapes that can reach support object, the invention is not restricted to above-mentioned detailed description of the invention.Bucking ladder 63 is also replaceable is any shape with guiding reed 3 downslide effects, and such as arc etc., detailed description of the invention is herein not used in restriction.
Principle and the process of the graver quick-replaceable blade of the present embodiment are as follows:
Referring to Fig. 5, in the time that this graver has been assembled, blade is in the lock state, now, spring 5 is compressed, therefore its transition boss 43 by outside top rear bar 4 outwards pushes up rear bar 4, thereby pull out the knife rest 2 being fixedly connected with rear bar 4, now reed 3 is also pulled, the kink 321 of its second end 32 is positioned at the top of the bucking ladder 63 of knife bar 6, and the inserted sheet 322 of the second end 32 of reed 3 inserts in the through hole 23 of knife rest 2 and the fixing hole 11 of blade 1, the fixing effect of the bullet 26 of knife rest 2 front ends balances each other with the elastic force of spring 5, make the knife rest 2 of knife bar 6 interior settings, rear bar 4 grades are in suitable position, make in the unlikely cavity 61 that is drawn into knife bar 6 of blade 1, this state bottom knife 1 is fixing, can not change, when needs are more when allowing blade replacement, inwardly press the press section 44 of rear bar 4 with a hand, now spring 5 is further compressed, the knife rest 2 being fixedly connected with rear bar 4 moves forward, reed 3 moves forward with knife rest 2, and reed 3 moves forward and causes its second end 32 to glide along the bucking ladder 63 of knife bar 6 inside, thereby the inserted sheet 322 that the second end 32 of reed 3 is arranged drops out the fixing hole 11 of blade 1, state now, referring to Fig. 6, at this moment can be extracted blade 1 to change out with another hand or tweezers.More finish changing after blade 1, unclamp the protuberance 44 of rear bar 4, draw back because the thrust of spring 5 makes rear bar 4, thereby the second end 32 of reed 3 is along moving on the bucking ladder 63 in knife bar 6, the inserted sheet 322 of reed 3 is popped up, insert in the fixing hole 11 of blade 1, thereby fixed blade 1.As above process, has just completed once the more flow process of allowing blade replacement.
The present invention by the rear bar that the knife rest of blade is set, be connected with knife rest, be enclosed within spring in rear bar and be set to interlock, and adopt to connect and be arranged on that flexible member on knife rest locks or the mode of release realizes the quick-replaceable of blade, this kind of graver only need be pressed graver rear in the time of allowing blade replacement more, just can carry out the replacing of blade, blade is only finished changing and need be unclamped.Graver of the present invention is simple in structure, and parts are few, be easy to manufacture, and simple to operation.
