A tamper-proof sealing mechanism for protecting various adjustment/setting means comprises a sleeve ( 5 ) having cylindrical bores on either side of its middle wall ( 14 ) for covering the adjustment means ( 1, 2 & 3 ) from one side and sleeve locking nut ( 6 ) or alike from another side. A spring washer ( 13 ) or the like is provided on both the side of the middle wall ( 14 ) of the sleeve ( 5 ) for proper nut tightening. A sleeve locking nut ( 6 ) is provided next to the spring washer ( 13 ) i.e. from opposite side of the adjustment means. A plug ( 7 ) is positioned on one side of said sleeve ( 5 ) i.e. at counter bore ( 10 ) or the like to form permanent sealing in between plug ( 7 ) & sleeve ( 5 ).
