Detailed Description

Reference is made to the accompanying drawings. The utility model provides a special mounting tool of inflating valve extension pipe adopts the metal material preparation, including first end joint 1 and second end joint 2, the rotation axis of first end joint 1 and second end joint 2 is parallel, preferably collineation, and the rotation axis of first end also is the centre of rotation of coupling nut 101 on inflating valve extension pipe joint 100, also is the oral area axis of inflating valve 300 on the automobile rim.

The side of the first end joint 1 and the side of the second end joint 2 are connected through a connecting rod 3, the length of the connecting rod 3 can be changed according to different installation spaces of the inflating valve extension pipe, and the connecting rods with different length models can be designed to be matched with measuring tools for use. The length of the connecting rod 3 is preferably not less than the length of the external valve including the valve extension pipe joint 100. Reference numeral 200 is a connection hose between the connector 100 of the valve extension pipe and the valve of the valve extension pipe.

First end connection 1 matches with coupling nut 101 that inflating valve extends coupling 100, first end connection 1 can with coupling nut 101 is connected and is driven its rotation, second end connection 2 sets up connecting hole 20, connecting hole 20 with torsion measuring tool 400's connector 401 match and can with connector 401 is connected, make special mounting tool of inflating valve extension pipe can be driven rotatoryly by torsion measuring tool 400, and when torsion reached standard, the torsion was in the inherent numerical value of setting for at the beginning and can not increase, has made things convenient for workman's use.
