Air tool with air duster

Abstract

A conduit (18) for an air duster is branched from an intermediate part of an air conduit (17) interconnecting an air supply source (16), which supplies compressed air, and an air tool. A valve mechanism having a switchover valve (25) and operation means (35) is installed at the branched part. The switchover valve (25) is movable between a first position and a second position. At the first position, an upstream side conduit (17a) communicating with the air supply source (16) is connected to a downstream side conduit (17b), which communicates with a nailing device, and disconnected from the branched conduit (18) for an air duster. At the second position, the upstream side conduit (17a) is disconnected from the downstream side pipeline (17b) and connected to the branched conduit (18). The switchover valve (25) is operated by the operation means (35) from the outside.

Description

technical field [0001] The invention relates to a pneumatic tool with an air extractor, wherein the air extractor for pressing out compressed air is additionally coupled to a pneumatic tool such as a nailer. Background technique [0002] It happens, for example, when laying floors that during the work of driving nails into the substrate it is found that fine wood chips or shavings are left on the substrate of the flooring material. When a decorative material is laid on the substrate with those fine wood chips or wood shavings left as they are on the substrate and then a nail is driven into the substrate, the decorative material is nailed down while being partially separated from the substrate, which The flooring work has to be performed again due to wood chips or wood shavings remaining on the substrate. In order to prevent such inconvenience, the decorative material is placed after the surface of the substrate has been cleaned by an air cleaner for nailing work. However, ...

AI Technical Summary

Problems solved by technology

In addition, since a configuration is adopted in which the compressed air for the air cleaner is taken out from the main chamber (accumulation chamber) for driving nails, when the air cleaner operating part and the trigger lever are simultaneously operated, The nailer is driven in a state where the main chamber is under low pressure, thereby causing the following problems: nail hitting failure occurs due to insufficient output and the driving piston cannot be returned to its original position

However, this increases the number of components and constitutes a major factor in increasing the weight and production costs of the nailing machine

[0011] (4) Because the button for the air cleaner and the actuation trigger lever of the nailer are positioned relatively close to each other, it is possible to perform nailing work while using the air cleaner, thereby causing the risk of accidents
