For example: if the pivot 3 rotates to the inner surface 14, if the friction torque value formed with the first covering end 11 is 5kg/cm, and if the friction torque value formed with the second covering end 12 is 4kg/cm cm, the accumulated friction torque value can be 9kg/cm; if the pivot 3 rotates to the outside, due to the effect of the opening 15, if the friction torque value formed with the first cladding end 11 is 3kg/cm, compared with If the friction torque value formed by the second coating end 12 is 2kg/cm, the accumulated friction torque value can be 5kg/cm; therefore, the "positive contrast" of the total friction torque can reach about 4kg/cm9kg/cm-5kg /cm=4kg/cm. However, before accumulation, the "positive contrast" of the friction torque formed by the first covering end 11 is about 2kg/cm (5kg/cm-3kg/cm=2kg/cm), and the friction torque formed by the second covering end 12 The "positive contrast" of friction torque is about 2kg/cm (4kg/cm-2kg/cm=2kg/cm), but the preferred embodiment of the present invention can effectively adjust the "positive contrast" of friction torque, so that the total friction The "positive contrast" accumulated by the torque can be as high as 4kg/cm9kg/cm-5kg/cm=4kg/cm, which is the "cumulative" torque adjustment effect. the

Please refer to Fig. 4, the covering part 1 can also have a first covering end 11, a second covering end 12 and a third covering end 13, the openings 15 of the first, second and third covering ends are in the same direction and All towards the inner side, and make the apertures of the first and third cladding ends 11 and 13 smaller than the aperture of the second cladding end 12; , 12, 13 respectively form the first friction torque, the second friction torque and the third friction torque, wherein, the first and third friction torque values are greater than the second friction torque value. the

For example: if the pivot 3 rotates toward the inner surface 14, due to the effect of the opening 15, if the friction torque value formed with the first covering end 11 is 3kg/cm, the friction torque formed with the second covering end 12 If the torque value is 6kg/cm, the accumulated friction torque value can be 9kg/cm; if the pivot 3 rotates outward, if the friction torque value formed with the first cladding end 11 is 5kg/cm, due to the opening 15, and if the friction torque value formed with the second covering end 12 is 2kg/cm, then the accumulated friction torque value can be 7kg/cm; therefore, even if the first and second covering ends 11a, 12a have For the opening 15 in the opposite direction, the "positive contrast" of the total friction torque can still be stably maintained at 2kg/cm9kg/cm-7kg/cm=2kg/cm, and will not completely cancel and return to zero. the
