2, the internal tooth of turning set is a complete circle, for turning set provides the rotational angle of maximum magnitude.
3, guide rail side has stroke bar hole, and the sliding bar of expansion bracket inserts a caging bolt, and caging bolt stretches out stroke bar hole, and caging bolt can prevent expansion bracket from being pulled out seat board.
4, the two ends of king-rod are provided with knob, are convenient to rotate king-rod.
5, be provided with antifriction cover between king-rod and turning set, can prevent king-rod and turning set friction from sending the sound, also can increase service life.
6, planar bottom surface arranges magnet, and foot-operated end face arranges iron plate, rides and can be adsorbed on the first rotor plate, saves space, easy to operate.
7, the second rotor plate bottom surface has groove, and the front end of groove has dodges mouth, and establish a bumping post in groove, foot-operated side has flat hole, and the opening part of flat hole is provided with block, and block blocks bumping post, and this structure can prevent from riding and be pulled out the second rotor plate.
