Summary of the invention

The purpose of this utility model is for overcoming the deficiency of prior art, a kind of improved hand-held pneumatic nail rifle is provided, making the mechanism of safety device more simple, and use very convenient, safe and reliable.

The purpose of this utility model is achieved in that a kind of improved hand-held pneumatic nail rifle, in the vertical part of the body of a gun cylinder is installed, and is cylinder head on the cylinder, and the cylinder head top also has an end cap, is provided with air valve between cylinder head and end cap; Piston is arranged in the cylinder, fix a striker on the piston; Be connected with the nailing guide plate in body of a gun bottom, nailing guide plate side connects a nail box; The lateral part of rifle body is an operating grip, its inner chamber is a breather chamber, afterbody has an air inlet pipe, handle and the nail box below it fix, be provided with intake valve below the front portion of handle, the valve rod of control intake valve switch contacts with trigger, trigger is fixed on the housing by pivot pin, be provided with air inlet switch stops in the trigger, this stops is contained on the axle center by pipe spreader with the trigger spring, stops is transferred with the rotation of trigger spring, slide bar contact under trigger spring and the trigger is connected, and the other end of slide bar under the nailing mouth, and exposes a segment length along nailing guide plate one, slide bar spring contact under slide bar outside the nailing guide plate has a bifurcated and is fixed on housing is connected, and with spring force slide bar is resetted; During use if nailing mouth misalignment station cocking, because stops withstands housing, trigger can not press air inlet valve lever, can't open intake valve, have only, will push up on the slide bar when nailing mouth contact station, promoting the trigger spring reverses, stops moved and did not withstand casing this moment, can firing trigger, open intake valve;

For the gas that makes discharge does not spray towards the direction that the people is arranged, the periphery of end cap be provided with one can 360 ° of rotations the collar, this collar is connected by steel ball (2) with end cap, and several exhaust holes are arranged on the collar, during use aperture is operated towards unmanned direction.

Since adopted technique scheme, a kind of improved hand-held pneumatic nail rifle of the utility model, and the safety device structure is very simple, and easy to use, good reliability; The exhaust collar of setting up can be avoided discharging gas effectively and spray to other people, injures human body.
