The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
To shown in Figure 11, a kind of ammunition ail shooter comprises overcoat 4 and firing pin 10 such as Fig. 1.The top of overcoat 4 is provided with for ammunition and picks and places a mouthful 4a.The rear end of overcoat 4 is fixed with urosome 16, is provided with on the urosome 16 to hold the through hole that firing pin 10 passes through.Urosome 16 is connected with the handle pad with handle 11 and is connected by set bolt 18.
Be combined with piston cylinder 3 in the overcoat 4, be provided with piston 5 in the piston cylinder 3.The front end of piston cylinder 3 is connected with nail pipe 2, and the rear end is set with thread bush 6.The front end of overcoat 4 is provided with spacer pin 24, and piston cylinder 3 is provided with the chute 3a corresponding with spacer pin 24.
The rear portion of piston cylinder 3 is provided with ladder tubular cartridge chamber lid 7, and thread bush 6 covers 7 threaded engagement with cartridge chamber.Be provided with cartridge chamber body 14 in the cartridge chamber lid 7, be provided with ejection return spring 15 between cartridge chamber body 14 and the thread bush 6.
Overcoat 4 rear portions interior, cartridge chamber body 14 are provided with striker post 9, are provided with the hit pinhole 9a of perforation in the striker post 9, and the head of firing pin 10 is positioned at hit pinhole 9a.Be provided with the guide slot 9b of an end opening on the striker post, be fixed with in the overcoat 4 with guide slot 9b accordingly without thread orientation pin 8.
The rear portion of cartridge chamber lid 7 has been wholely set boss 7a, and the front portion of striker post 9 is provided with groove 9c, and boss 7a cooperates with groove 9c male and female.
The bottom of handle 11 is provided with the positive hole 11a of cover, and handle pad 12 is provided with the positive boss 12e of cover corresponding to the positive hole 11a of cover, overlaps positive boss 12e point diameter and evenly increases progressively from front to back.
The rear portion of overcoat 4 is provided with the firing pin switching mechanism, and the firing pin switching mechanism comprises trigger 13 and is positioned at the sear 20 of trigger 13 tops, between trigger 13 and the handle 11 trigger spring 19 is set.
Be provided with the perforate 20a corresponding with hit pinhole 9a on the sear 20 and close hole 20b, perforate 20a is positioned at the below of closing hole 20b, and the two is connected with each other.Perforate 20a diameter is greater than closing hole 20b diameter, so firing pin 10 can be by perforate 20a, but can not be by pass hole 20b.
Be provided with firing pin marshall springs 21 between striker post 9 and the urosome 16.
Be provided with the firing pin chamber 11c that holds firing pin 10 rear portions in the handle 11, the rear portion of firing pin 10 is wholely set limited location boss 10a, is provided with striker spring 22 between the bottom of positive stop lug boss 10a and firing pin chamber 11c.
During ail shooter work, at the front end pilot nail shroud 1 of nail pipe 2, nail is put into the nail pipe, nail shooting pill is put into cartridge chamber body 14.Under the original state, the hit pinhole 9a that closes hole 20b and striker post 9 over against, close the major part that hole 20b limits firing pin 10 and enter in the hit pinhole 9a, striker spring 22 is in compressive state.
Nail shroud 1 is covered the position of wanting nailing, and cocking 13, trigger 13 be sear 20 jack-up upwards, thus perforate 20a and hit pinhole 9a over against, firing pin 10 enters rapidly striker post 9 under the effect of striker spring 22, its head tip hits ignition nail shooting pill.Piston 5 travels forward rapidly under the effect of explosion gas, impacts the nail in the nail pipe 2, thereby nail is hammered into the nailing position.
On the other hand, because cartridge chamber lid 7 and striker post 9 male and females cooperate, striker post is just being overlapped automatically, effectively pull the trigger to guarantee ammunition; Simultaneously, when the quick-fried bullet of unexpected generation occurring, can effectively avoid operator and the injury of object generation on every side.
As shown in figure 12, finish nailing after, pulling nail pipe 2 forward, thus drive piston cylinder 3, thread bush 6 and 7 reaches of cartridge chamber lid, until limited pin 24 restrictions of the end face of thread bush 5.Continue pulling nail pipe 2, piston cylinder 3 is moved on, piston cylinder 3 produces relative motion with thread bush 6, until the relative position between piston 5 and the piston cylinder 3 is returned to original state.In this process, ejection return spring 15 is compressed, produces relative motion between cartridge chamber body 14 and the cartridge chamber lid 7, thereby shell case 25 is broken away from from cartridge chamber body 14.
Make backward motion of nail pipe 2, thereby make piston cylinder 3, piston 5, cartridge chamber body 14 and cartridge chamber lid 7 be returned to original state.In this process, cartridge chamber body 14 is returned to the relative position with the original state of cartridge chamber lid 7 under the effect of ejection return spring 15, and the rear portion of shell case 25 from cartridge chamber body 7 ejected, and picks and places a mouthful 4a taking-up from ammunition.
When handle 11 and handle pad 12 are installed, the positive boss 12e of cover is inserted in the positive hole 11a of cover, then guide ledges 12f is cooperated with pilot hole 11b, install bolt 18 and get final product.Because the positive boss 12e point diameter of cover evenly increases progressively from front to back, but so auto lock handle 11 and handle pad 12.The kick of ail shooter will be absorbed by the damping net, thereby greatly reduce staff to the induction of kick.Because guide ledges 12f, pilot hole 11b, the positive boss 12e of cover and the setting of overlapping positive hole 11a can guarantee handle and the direct installation accuracy of handle pad, and easy for installation.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all in the art technical staff comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
