The range adjustable pistol comprises a barrel and a handle, wherein the barrel comprises an outer barrel and an inner barrel; the inner barrel is sleeved with the outer barrel in a rotary manner; energy discharge holes are formed in the inner barrel; energy discharge channels are arranged on the inner sides of the outer barrel; air holes communicated with the energy discharge channels are formed at the end of a muzzle of the outer barrel; an energy discharge hole switch is arranged on the handle and is connected with the outer barrel by a connecting rod. The range adjustable pistol provided by the utility model simultaneously has the functions of short-range pistols and long-range pistols.

Description

A kind of adjustable range pistol

Technical field

The utility model relates to a kind of adjustable range pistol.

Background technology

Pistol is a kind of short barrel weapon that is hold by one hand the shooting of aimed fire or instinct, is generally commander and special technical soldier carries, and is used in 50 meters of short ranges and defends oneself and surprise attack enemy.The basic characteristics of modern pistol are: conversion insurance, bullet load, change magazine conveniently, compact conformation, and automated manner is simple.Modern military pistol mainly contains self-defence pistol and machine pistol.Self-defence pistol range is generally 50 meters, 8～15 of capacity of macromolecule, and radiation pattern is single-shot, weight is 1 kilogram of left and right.Machine pistol is also fight pistol, full-automatic, is generally furnished with separate type gun stock, and 10～20 of capacity of macromolecule can be worked as at ordinary times tommy gun and be used, and effective range can reach 100～150 meters.Modern pistol mainly contains revolver, automatic pistol (actual is semi-automatic handgun), machine pistol three types.

Conventional pistol bullet range is non-adjustable, bullet far firing range, and the power of pistol is large, easily causes unnecessary injury, particularly stray bullet to be easy to hurt innocent persons.

Utility model content

In order to reduce the power of pistol when the short range, during long-range, keep the power of pistol, the utility model provides a kind of adjustable range pistol.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of adjustable range pistol, comprise gun barrel and pikestaff, and described gun barrel comprises outer gun barrel and internal layer gun barrel, described outer gun barrel rotary sleeve is outside described internal layer gun barrel; Described internal layer gun barrel is provided with and unloads energy hole; Described outer gun barrel inner side is provided with that unloads can passage, and described outer gun barrel muzzle one end is provided with and the described pore can passage communicating that unloads, and described pikestaff is provided with that unload can hole switch, described in unload and can by connecting rod, be connected with described outer gun barrel by hole switch.

As preferably, described in unload can hole, unload can passage and described pore be that number is all four.

As preferably, described in unload and can evenly be arranged on internal layer gun barrel in hole.

Compared with prior art, the utility model has the advantages that: in the time need to using the pistol of short range, low power, open and unload energy hole switch, unload and can by connecting rod, drive outer gun barrel to rotate by hole switch, making to be located at unloading of outer gun barrel inner side can passage and be located at unloading on internal layer gun barrel and can communicate in hole, lays down bullet part energy, thereby shortens pistol shot, reduce bullet power, reduce unnecessary injury, avoid hurting innocent persons.When needs are long range, close and unload energy hole switch, unload and can by connecting rod, drive outer gun barrel to rotate by hole switch, making to be located at unloading of outer gun barrel inner side can stagger with the unloading energy hole being located on internal layer gun barrel by passage mutually, does not communicate, and bullet keeps original range.Adjustable range pistol provided by the utility model possesses the function of short range pistol and long-range pistol simultaneously, has good DEVELOPMENT PROSPECT, can produce good economic benefit and social benefit.

Fig. 4 is that Fig. 2 is along the cutaway view of A-A.

Shown in figure: the outer gun barrel of 1-gun barrel, 2-pikestaff, 3-, 4-internal layer gun barrel, 5-unload can hole, 6-unloads can passage, 7-pore, 10-unloads can hole switch.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail: embodiment mono-: please refer to Fig. 1 to Fig. 4, a kind of adjustable range pistol, comprise gun barrel 1 and pikestaff 2, described gun barrel 1 comprises outer gun barrel 3 and internal layer gun barrel 4, and described outer gun barrel 3 rotary sleeves are outside described internal layer gun barrel 4; Described internal layer gun barrel 4 is provided with and unloads energy hole 5; Described outer gun barrel 3 inner sides are provided with unloads energy passage 6, described outer gun barrel 3 muzzle one end are provided with and the described pore 7 can passage 6 communicating that unloads, described pikestaff 2 be provided with unload can hole switch 10, described in unload and can by connecting rod, be connected with described outer gun barrel 3 by hole switch 10, connecting rod can be iron wire.Described unload can hole 5, unload can passage 6 and described pore 7 be that number is all four.Described unloading can evenly be arranged on internal layer gun barrel 4 in hole 5.

Can hole during switch 10 place open mode when unloading, unloading of outer gun barrel 3 inner sides can passage 6 and be located at unloading on internal layer gun barrel 4 and can communicate in hole 5; Can hole during switch 10 place closed condition when unloading, unloading of outer gun barrel 3 inner sides can passage 6 and be located at unloading on internal layer gun barrel 4 and can mutually stagger in hole 5, does not communicate.

Please refer to Fig. 3, in the time need to using the pistol of short range, low power, open and unload energy hole switch 10, unload and can by connecting rod, drive outer gun barrel 3 rotations by hole switch 10, being located at unloading of outer gun barrel 3 inner sides can passage 6 and be located at unloading on internal layer gun barrel 4 and can communicate in hole 5, lays down bullet part energy, thereby shortens pistol shot, reduce bullet power, reduce unnecessary injury, avoid hurting innocent persons.

Please refer to Fig. 4, when needs are long range, close and unload energy hole switch 10, unload and can by connecting rod, drive outer gun barrel 3 rotations by hole switch 10, being located at unloading of outer gun barrel 3 inner sides can stagger with the unloading energy hole 5 being located on internal layer gun barrel 4 by passage 6 mutually, do not communicate, bullet constant in energy, keeps original range.The adjustable range pistol that the present embodiment provides possesses the function of short range pistol and long-range pistol simultaneously, has good DEVELOPMENT PROSPECT, can produce good economic benefit and social benefit.
