The utility model relates to a kind of hand-held small arms, is a kind of variable bullet kind, bullet diameter changeable pistol.

Existing pistol, generally by gun barrel, the rifle body, trigger, parts such as hammer and magazine are formed, the emission of bullet, usually adopt pipe withdrawing type and blowback automatic principle, structures such as magazine ammunition feed, for example homemade the May 4th formula, six or four formula pistols all can only be launched the bullet of a certain specification, fatal range can reach hundred meters, be suitable for hostile gunbattle, but, limited its use on the contrary in some occasion, for example when processing can not cause death criminal or be seriously wounded or disabled, in the many occasions of the on-the-spot masses of making trouble, because of hurting innocent persons easily, the main feature of these weapons has but limited its normal use on the contrary.

The purpose of this utility model is the deficiency at above pistol, design a kind of low power, the extraordinary guard pistol of variable bullet kind, variable caliber, can launch dissimilar pistol cartridges, thereby have functions such as killing and wounding, cause injury, break tear, signal, burning concurrently, its magazine is a bomb tube, is quick separation and combination type with the rifle body, when changing different calibers, dissimilar bullet, can launch dissimilar pistol cartridges.

The purpose of this utility model is achieved through the following technical solutions:

General pistol all comprises rifle body, trigger, hammer, dead lock etc., and the utility model is newly to have designed a locking discharging mechanism and an interlock firing lock.The locking discharging mechanism is made up of locking screw socket, locking rammer, spring leaf.The locking screw socket is located at rifle body transmitting tube front end, and the locking rammer is installed in the top of rifle body transmitting tube afterbody, and spring leaf is installed in the below of locking rammer.The interlock firing lock is made up of trigger assembly and hammer assembly two parts.The trigger assembly comprises trigger, trigger spring, trigger sear, trigger spring pin, trigger guard, retainer pin.Trigger is installed in the trigger guard, and trigger guard is fixed on the rifle body by retainer pin, and trigger is connected with the trigger sear, and trigger sear front end is equipped with trigger spring and trigger spring pin.The hammer assembly comprises firing pin, firing pin screw plug, hammer, hammer spring, hammer pin, hammer spring backing pin.Hammer is installed in the pikestaff top at rifle body rear portion, hammer and hammer pin are fastened on the rifle body, hammer spring and hammer spring backing pin are housed in the hammer, be shaped on the hammer auxiliary catch on the hammer, auxiliary catch coupling location and installation on hammer auxiliary catch and the trigger sear, firing pin is equipped with in afterbody corresponding position at the rifle body transmitting tube in hammer the place ahead, adopts the firing pin screw plug that the firing pin location is packed on the rifle body.

The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment:

Fig. 1 is the utility model structural representation.

1-locking screw thread, 2-rifle body, 3-firing pin, 4-locking rammer, the 5-spring leaf, 6-firing pin screw plug, 7-hammer pin, 8-hammer, 81-hammer auxiliary catch, 9-hammer spring, 10-hammer spring backing pin, the 11-pikestaff, 12-trigger sear, 121-trigger sear auxiliary catch, the 13-retainer pin, 14-trigger, 15-trigger guard, 16-trigger spring, 17-trigger spring pin, 18-rifle body transmitting tube.

Referring to shown in Figure 1, during enforcement, manufacture experimently a locking discharging mechanism and formed by locking screw socket 1, locking rammer 4, spring leaf 5.Front end at rifle body transmitting tube 18 is shaped on locking screw socket 1, and locking rammer 4 is installed above rifle body transmitting tube 18 afterbodys, and spring leaf 5 is equipped with in the below of locking rammer 4.

Make an interlock firing lock, it is made up of trigger assembly and hammer assembly two parts.The trigger assembly is to comprise trigger 14, trigger spring 16, trigger sear 12, trigger spring pin 17, trigger guard 15, retainer pin 13.Trigger 14 is installed in the trigger guard 15, and trigger guard 15 is fixed on the rifle body 2 by retainer pin 13, and trigger 14 is connected with trigger sear 12, and trigger sear 12 front ends are equipped with trigger spring 16 and trigger spring pin 17.The hammer assembly comprises firing pin 3, firing pin screw plug 6, hammer 8, hammer pin 7, hammer spring backing pin 10.Rifle body 2 rear portions above pikestaff 11 are equipped with hammer 8, hammer 8 is fixed on the rifle body 2 by hammer pin 7, hammer spring 9 and hammer spring backing pin 10 are housed in the hammer 8, be shaped on hammer auxiliary catch 81 in the hammer 8, the auxiliary catch 121 coupling location and installation of hammer auxiliary catch and trigger sear, firing pin 3 is equipped with in afterbody corresponding position at the rifle body transmitting tube 18 in hammer 8 the place aheads, adopts firing pin screw plug 6 that firing pin 3 location are packed on the rifle body 2.

The utility model is when using operation, the hammer 8 of this pistol is in relaxation state when flat and compresses firing pin 3 outstanding striker posts, at first hammer 8 is pulled backward an angle before shooting, hammer auxiliary catch 81 is hung on the firing trigger sear auxiliary catch 121, be the insurance state.Again that difference is special magazine screws locking screw socket 1 by its closedown structure requirement from the insertion of muzzle direction muzzle-loading projectile and puts in place, and special magazine rear portion locking groove is also finished the hook locking by locking rammer 4.During emission, be pressed onto behind the position again automatically arm after hammer 8 continued and finish the on-hook action, be arm-to-arm, cocking 14, then trigger 14 is stirred 12 reaches of trigger sear, discharges hammer 8 simultaneously, bump firing pin 3 under the effect of hammer spring 9, bullet is penetrated, and finishes emission process.Before the emission, screw out magazine and shell case once more, and new clothes go into pistol cartridge, use by the aforesaid operations requirement from muzzle.

The utility model has following characteristics:

1. multipurpose, variable bullet kind, variable caliber. One rifle is multiplex, can launch the service pistol bullet, again can civilian pistol cartridge, different pistol Non Fragmentation kinds such as emission blank cartridge, rubber bullet, plastics bullet, steel ball shot, tear bombnoun, signal flare, firebomb, flare, be not subjected to the restriction of bullet kind bore yet, can be according to requirements, change magazine transmitting tube cartridge chamber, gun barrel bore, thereby can launch 7.62 millimeters formula on May Day, six or four formula pistol cartridge and blank cartridges, 9 millimeters five or nine formula pistol cartridges, 5.6 millimetres of movement rifle length bullet, 11 millimeters life saving signal bullets etc.

2. has selectable dual-purpose blocking device. General pistol only has a kind of closedown mode, and the utility model has adopted two kinds of different blocking devices, i.e. muzzle-loading projectile locking screw type and have the locking rammer of the function that extracts concurrently adapting to the locking requirement of different magazines, and does not hinder mutually. More superior than other pistol.

3. the shift-forward type trigger sear that has the band insurance. Different from general pistol sear, its structure is very simple, and the existing effect of playing the percussion insurance can be played again the effect of sear.

4. the utility model simple structure, volume is small and exquisite, in light weight.Need not decompose just and can maintain, no gunpowder erosion in the rifle.Because magazine is that smooth bore tube, gun pressure are low, muzzle energy is less, so kick is little during shooting, close range shooting is to targeting rate height, and non-lethal pistol cartridge has bigger non-deadly attack effect, to certain simple target shooting, can not injure other people.

5. because magazine and rifle body are the split state at ordinary times, generally be no gun barrel state, therefore, can avoid the generation of contingency.Wherein magazine has the special-purpose Non Fragmentation of locking groove, can shoot fast, extracts, ejection.The cylindricality, sphere, nonmetal bullet 2-10 that also can hold the 10-20 mm dia in the magazine.
