It being equipped with and is equipped with tread plate with one matched screw thread two of screw thread, two outside of the protective shell, the protector one is regular hexagonal prism,
And the protection groove shape is that size is identical as nut.
Furthermore, the protector two is cylinder, and diameter is equal to the circumscribed circular diameter of nut.
Furthermore, the length of the bolt and two deep equality of protective shell.
Furthermore, the tread plate is parallel is set to two outside of protective shell, and the spacing of adjacent two tread plates
From identical.
Advantageous effect of the present invention：Due to being equipped with protective shell one and protective shell two, screw can be protected, when preventing long
Between the phenomenon that causing corrosion with air, contact with moisture, influence the service life and beauty of screw, while can also play the work of protection
With material can be consolidated according to the pressure requirements of material due to being equipped with adjustable spring by preventing the corner angle of screw from scratching personnel
It is fixed, it prevents from damaging material because pressure is excessive, or due to not causing to shake by nut tightening, due to being equipped with screw thread
Protective shell two can be fixed with screw, prevents from falling off by slot, can also improve the stability that nut is tightened with bolt, keep away
Exempt from the loosening of mechanically vibration or pressure change appearance or fall off, due to being equipped with anti-skidding global tread plate, work can be facilitated
Installation and dismounting of the personnel to protective shell.
