Extraction Connection System

Abstract

The disclosure relates to an extraction connection system for portable machine tools, and comprises at least one tool connection element, at least one suction apparatus connection element, and at least one fixing unit. The at least one tool connection element is configured to be connected to the at least one suction apparatus connection element. The at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.

1 . An extraction connection system for portable machine tools, comprising:
 at least one tool connection element;   at least one suction apparatus connection element, the at least one tool connection element configured to be connected to the at least one suction apparatus connection element,   at least one fixing unit including at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.   
     
     
         2 . The extraction connection system as claimed in  claim 1 , wherein the at least one fixing element is mounted movably on the at least one suction apparatus connection element. 
     
     
         3 . The extraction connection system as claimed in  claim 1 , wherein the at least one fixing element is positioned in a receiving recess of the at least one suction apparatus connection element. 
     
     
         4 . The extraction connection system as claimed in  claim 1 , wherein the at least one fixing element having an annular shape. 
     
     
         5 . The extraction connection system as claimed in  claim 1 , wherein the at least one fixing element has is least one articulation region. 
     
     
         6 . The extraction connection system as claimed in  claim 1 , wherein the at least one tool connection element comprises at least two connecting regions which differ from each other with respect to a connecting direction of movement of the at least one tool connection element. 
     
     
         7 . The extraction connection system as claimed in  claim 1 , wherein the at least one fixing unit comprises at least one spring element configured to apply a spring force upon an operating element of the at least one fixing unit. 
     
     
         8 . The extraction connection system as claimed in  claim 1 , wherein the at least one fixing unit comprises at least one operating element configured to selectively move the at least one fixing element into a release position. 
     
     
         9 . The extraction connection system as claimed in  claim 1 , wherein the at least one fixing unit comprises at least one operating element having an annular shape. 
     
     
         10 . The extraction connection system as claimed in  claim 1 , wherein the at least one tool connection element has at least one fixing element decoupling surface configured to move the at least one fixing element into a release position. 
     
     
         11 . (canceled) 
     
     
         12 . A tool device, comprising:
 a portable machine tool; and   an extraction connection system having at least one tool connection element at least one suction apparatus connection element, and at least one fixing unit,   wherein the at least one tool connection element is configured to be connected to the at least one suction apparatus connection element; and   wherein the at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.   
     
     
         13 . (canceled) 
     
     
         14 . A device, comprising:
