BACKGROUND OF INVENTION
In few applications, screw in the connector needs to be removed before
assembly in electronics PCBs. This type board have slot in PCBs which will
be sit in the screw slot in connector. Only standard tool available are not
suitable for the said application. There was a requirement of special tool to
remove the screw in connector.
SUMMARY OF INVENTION
In accordance of invention, first aspect of invention is to make convenient
removal of the screw by holding the head of the screw.
Second aspect of the invention is to remove screw by rotating of the head of
connecter screw in board.
In accordance of invention, bar is attached to the wrench to provide 360
degree rotation in clock wise/ anti clockwise.
Another aspect of the invention, holding Bar is to provide the grip on the
wrench during operations.
Another aspect of the invention is to provide deep slot play area suitable with
the head of screw in connector.
Another aspect of invention is to provide sufficient length of the wrench
suitable to removal of the screw in connector.
Another aspect of the invention is to apply little force/torque for removal of the
screw in board and make easier assembly of the control board in assembly.
Another aspect of the invention is to provide light weight, handy suitable to
applications.
Another aspect of the invention is to provide little higher diameter at the user
hand and lesser diameter at the tip for easy gripping to user and tip’s free
movement in screw slot.
BRIEF DESCRIPTION OF DRAWING
These as well as features of the Present Invention will become more apparent
upon reference to the drawing where in:
Fig-1 is Front view of the Box Wrench.
Fig-2 is Bottom view of the Box Wrench.
DETAILED DESCRIPTION
Referring Fig.1& Fig.2, the present invention is a Box wrench 3 which
tight the work piece, its invention relates to tightening/opening of the Work
piece.
Box Wrench 3 comprises a Spanner1 of St. Steel having hole on the
Surface C of the Spanner. Width & Depth of the slot play an important roll for
the tightening / opening of the work piece. The slot area is suitable to the
head of the screw and provide sufficient grip to the head of screw for the
movement. Box wrench 1 provides bigger diameter at the user end for easy
gripping and smaller diameter at the tip for free movement in screw slot. With
the smaller diameter, the bar is easily inserted in the slot area of screw in
connector
The slot area fitted in the head of screw and provides support for
operation Spanner1 have a Hole in it where holding Bar 2 is fixed to hold the
spanner during operation. The holding bar provide grip in hand during
operation. The holding bar also provides rotation to the screw in
clockwise/anti-clockwise upto 360 degree. The holding bar provide facility for
removal of screw with less force/torque.
Box Wrench 3 comprises Holding Bar 2 of Std. Dowel Pin fix with the
spanner1 in the Hole provided in spanner. It provides proper torque to the
spanner during operation.
The said invention provides facility for removal of the screw by holding
the head of the screw and rotating it in anti-clock wise direction/ insertion of
screw by holding the head of screw and rotating it in clockwise direction
The invention is light weight, handy, portable suitable to applications.
