Patent ID: 7007929

Claim:
A wire stranding roller for a LP insulator, comprising: an upper supporting unit ( 10 ) having a front supporting bracket ( 11 ), a rear supporting bracket ( 11 ′), a cross beam ( 15 ) transversely fixed between said front and rear supporting brackets ( 11 , 11 ′), an upper roller ( 12 ) axially and rotationally mounted underneath said cross beam ( 15 ) and a handle ( 13 ) fixed on top of said cross beam ( 15 ), a pair of left and right vertical supporting units ( 20 ), each vertical supporting unit ( 20 ) having a vertical rear bracket ( 22 ), and a vertical rear roller ( 21 ) axially and rotationally mounted on said vertical rear bracket ( 22 ), an insulator coupling unit ( 30 ) having a pair of left and right base frames ( 33 ), each base frame ( 33 ) formed integrally and perpendicular to said vertical rear bracket ( 22 ), a pair of symmetrically split half insulator pads ( 31 ) with semi-circular center cut outs, each split half insulator pad ( 31 ) installed inside of each base frame ( 33 ), a rear hinge ( 34 ) for hinging said left and right base frames ( 33 ), and a screw-type clamp ( 32 ) for clamping said left and right base frames ( 33 ), and a pair of left and right open-and-shut units ( 40 ), each open-and-shut unit ( 40 ) having a roller supporting beam ( 41 ) axially and rotationally hinged inside said base frame ( 33 ), a base roller ( 43 ) axially and rotationally mounted inside said roller supporting beam ( 41 ), and a front roller ( 42 ) axially and rotationally mounted perpendicular to said roller supporting beam ( 41 ), so that said left and right open-and-shut units ( 40 ) are bilaterally rotated with respect to their axis ( 45 ) of said roller supporting beams ( 41 ) for latching or unlatching to said front supporting bracket ( 11 ).
