Embodiment Construction

[0058] A first embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 6. FIG. This is a working tool driven by explosive force, by means of which the fastening element can be driven into the object.

[0059] A housing base 1 belongs to the mounting tool shown in FIGS. 1 to 3 , in which a cylindrical piston chamber 2 accommodates a drive piston 3 , which is displaceably mounted in the axial direction of the piston chamber 2 . The central axis of the piston chamber 2 is designated by reference numeral 4 and coincides with the longitudinal direction of the setting tool. Furthermore, inside the housing base body 1 there is a cylindrical recess 5 , the cylindrical axis 6 of which extends perpendicularly to the central axis 4 . At the base of the cylindrical recess 5 , this recess communicates with the piston chamber 2 via a connecting channel 7 extending coaxially to the central axis 4 .

[0060] Opposite the open side of the cylindrica...

Abstract

An explosion-operated power tool including a housing (1) having a cylindrical cavity (5) and a piston chamber (2) for receiving a drive piston (3) and communicating with the cavity (5), a breech bottom (8) located opposite the cavity (5) and fixedly secured at a predetermined distance from the housing (1), and a sealing sleeve (12) located in the cavity (5) and displaceable axially away from the breech bottom (8) and toward the breech bottom (8) for enabling, respectively, a sidewise feeding of a catridge (10) for positioning the catridge between the breech bottom (8) and the sealing sleeve (12),can be pressed by other hand against the percussion bottom to receive the cartridge (10).

Description

technical field [0001] The invention relates to an installation tool driven by combustion force. Background technique [0002] A setting tool driven by explosive force is known from DE 199 05 896 A1, which has a first part in the form of a guide cylinder and a second part in the form of an impact shoe. The two parts are arranged substantially coaxially with respect to each other and can be displaced relative to each other parallel to the mounting direction. The end region of the first part facing the impact base has an explosive chamber which accommodates the explosive chamber. A piston chamber is connected to the explosive chamber in the installation direction, in which a drive piston is arranged axially displaceable. The piston chamber is connected with the explosive chamber through a connection hole. [0003] On its side facing the pilot cylinder, the impact base supports an axially displaceable sealing bush. When an unused explosive is located in the explosive chambe...
