To make screws easier to remove, rub soap on the thread before screwing in. 螺钉旋进去之前擦些肥皂，可使螺钉更容易拧动。
In screwing down the bolts, the bolts can be tightened upwards to get the bolt clip in the groove at the upper bracket in order to prevent the clip from rotating with bolts. 拧紧螺栓时，可向上拉紧，使螺母卡在下支架的凹槽中，防止螺母跟随转动。
