When the rotating shaft 16 drives the circular gear 15 to rotate, one end of the card plate 20 can be moved between the two sets of gear teeth of the circular gear 15, thereby resisting and fixing the circular gear 15 to prevent it from rotating. When the terminal block 27 is adjusted to rotate in the opposite direction, by pressing the dial plate 21, the dial plate 21 can drive the rotating rod 19 and the card plate 20 to rotate, so that one end of the card plate 20 can be disengaged from the circular gear 15, facilitating the reverse rotation of the circular gear 15, so as to facilitate the reverse rotation adjustment of the angle of the terminal block 27, and thus complete the entire operation process.
