The specific embodiment

Below in conjunction with accompanying drawing 1-6, the utility model is done further detailed narration.

See also Fig. 1 and Fig. 2, it is respectively a kind of exploded view and stereogram from moving knife of side direction release blade.Comprise left handle of a knife 1, right handle of a knife 2, be arranged on the knife rest 12 between left handle of a knife 1 and the right handle of a knife 2 from moving knife.Wherein on the handle of a knife cutter storehouse 21 and a cutter storehouse lid 22 that is used to store some blades is set in left side handle of a knife 1, the right handle of a knife 2.In this example, be that cutter storehouse 21 and cutter storehouse lid 22 are set on the right handle of a knife 2.Be provided with on the knife rest 12 (seeing also Fig. 3) on the side 31 of blade bearing 12. blade bearings 12 be provided with can a ccontaining blade insert groove 32.

One side in cutter storehouse 21 is towards blade bearing 12, and its another side is towards cutter storehouse lid 22.On the cutter storehouse lid 22 elastic device is set, in this example, this elastic device is a stage clip 23, and stage clip 23 is used for a blade in cutter storehouse 21 is pressed in the insert groove 32.Insert groove 32 cutters 10 placement locations just overlap fully with the blade of the 21 li placements in cutter storehouse, if do not have blade on the insert groove 32, the most inboard cutter side that the cutter storehouse is 21 li can enter in the insert groove 32 under the effect of 22 compression springs 23 is covered in the cutter storehouse automatically.

See also Fig. 3, Fig. 4 and Fig. 5, a groove 35 is set on the another side 33 of blade bearing 13, a flywheel 4 is set in its groove 35.Flywheel 4 comprises between first projection 41 that is circular-arc and second projection, 42, the first projections 41 and second projection 42 first groove 45 and second groove 46 is set respectively.The center of flywheel 4 is provided with an axle center hole 44, and the axle center is arranged on the another side 33 of knife rest 13, and cage knob 4 rotates along the axle center.

In this example, on first projection 41 of flywheel 4, a shifting block 43 is set.This shifting block 43 can be made into integration with flywheel 4, also can connect merely.Described shifting block 43 also can substitute with other locking device.One through hole 6 is being set on knife rest 13, and the part of through hole 6 is positioned at insert groove 32.In this example, some grooves 11 are set on the blade 10, described through hole 6 can partly be positioned at a wherein groove 11 that is placed on insert groove 32 inner blades 10.Under normal conditions, shifting block 43 wore described through hole 6, blade 10 can be stuck in the insert groove, made blade 10 do horizontal movement with respect to blade bearing 13.That is, locking device (being shifting block 43) can be in through hole 6 under the effect of flywheel 4 activity realize blade in the locking/unlocking blade bearing.

One flywheel torsion spring 5 also is set on the another side 33 of blade bearing 13, and this flywheel torsion spring 5 is arranged in the groove 35.The end of flywheel torsion spring 5 is positioned at second groove, 46 described flywheels, the 4 movable ends that are connected in flywheel torsion spring 5, and the end of described flywheel torsion spring 5 props up under the state of flywheel 3 naturally, and flywheel 4 drives shifting block 43 lock knife bar inner blades.

On a wherein handle of a knife of left handle of a knife 1, right handle of a knife 2, a locked groove 7 is set.In this example, locked groove 7 is arranged on (being arranged on the left handle of a knife 1 in this example) on the left handle of a knife 1.One cage knob 8 is arranged in this locked groove 7, and the hole length of locked groove 7 is the stroke of cage knob 8, and cage knob 8 can be stirred in locked groove 7, and the activity of cage knob 8 can drive flywheel 4 motions.In this example, also comprise cage knob jump ring 15, cage knob jump ring 15 is in the rear of cage knob 7 ends.Cage knob 7 can only be slided front and back in the locked groove 7 of left handle of a knife 1 front by 15 controls of cage knob jump ring.

When cage knob 8 was toggled it to the rear end at locked groove 7 by external force, the end of cage knob 8 promoted flywheel 4 and rotates up, and compression flywheel torsion spring 5 and cage knob torsion spring 15, flywheel 4 promptly drive shifting block to the motion of the top of through hole, and blade 10 gets final product release.When 8 groups of cage knobs were got back to the front end of locked groove 7, when perhaps external force disappeared, under the effect of cage knob button spring 125, cage knob 8 left first groove 45, and flywheel 4 can make that under the effect of flywheel torsion spring 5 shifting block 43 is positioned at the bottom of through hole 6, realized the effect of locking blade.In knife rest during no blade, stir cage knob 8, make cage knob drive flywheel 4 motions, the most inboard cutter side that the cutter storehouse is 21 li can enter in the blade bearing 32 under the effect of 22 compression springs 23 is covered in the cutter storehouse automatically, when 8 groups of cage knobs are got back to the other end of locked groove 7, cage knob 8 leaves first groove 45, and flywheel 4 can make that under the effect of flywheel torsion spring 5 shifting block 43 is positioned at the bottom of through hole 6, realizes the effect of locking blade.

More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
