Description

The invention relates to pneumatic manual nailing devices and has been used in various industrial applications.

A pneumatic pistol is known, which contains a working cylinder, inside which a piston with a die is located and a movable and podprugshnekny axially enclosing cylinder containing a handle, in which a valve is placed for putting the gun into operation, after pressing the handle, in which the working cylinder is fitted Interaction with the valve when pressing the handle with a spring-locked trigger with a safety catch 1.

In this gun it is complicated according to the scheme, design and manufacture of the fuse box of the safety device. In addition, the bracket itself is constantly under the impact of shocks and vibrations, which the cylinder of the impact mechanism experiences from the striker at the end of the hammering, as a result of which the elements of the chassis and cylinder are subject to intensive wear at their contact, which during long-term work leads to the formation of excessive play, leading to the failure of the work of the safety device and the need to replace its parts with new ones.

The presence of such a complex safety device complicates the assembly, disassembly and repair of the tool as a whole. For example, in order to remove the repair knob from the body of the percussion mechanism from the handle of the percussion mechanism for the purpose of repair, it is necessary to disassemble the safety device assembly, which cannot be done without dismantling the shop elements, etc.

Closest to the invention of technical knowledge, is a pionmatological nail gun, comprising a housing with a handle, a stepped working cylinder located in it, located in the last spring-loaded firing pin. pkvaya shev.moklapan and start-protection mechanism, having a hingedly mounted on the body and spring-loaded with respect to him kufok with iheptalom and rocker arm 2.

The aim of the invention is 11) the sense of design and increased safety of work

This is achieved by the fact that this worker is made with zshor, which is interlocking with the trigger sear, one arm of the rocker arm interacts with the starting pneumocaglar, and the other with the working chadiadad.

In the drawing e schematically depicts the forward pistol.

 The gun contains a housing 1, inside which is placed a hammer mechanism 2, spring-loaded 3. A shock mechanism contains a barrel 4, a shaft 5, a paddle 6 of a shaft 5 and a spring-loaded piston hammer 7, placed in a working id 5.
