Through the setting of the locking connection mechanism, turn the handle of the screw rod 16 in the circular groove 13 clockwise. The external thread cylinder 15 rotates in the internal thread hole 14 and moves into the through hole 11. When the limit ring 23 abuts against the inside of the circular groove 13, stop rotating. Then rotate the screw rod 16 counterclockwise. The rotation of the screw rod 16 drives the adjusting block 17 to move.
