Further improvement: the adjusting seat A or the adjusting seat B is provided with a threaded hole, the adjusting seat B or the adjusting seat A is provided with a perforation, the adjusting seat A and the adjusting seat B are connected through a locking nut, the locking nut is connected with the threaded hole after penetrating through the perforation, and the axis of the locking nut is perpendicular to the axis of the through hole.
Further improvement: the adjusting seat A is connected with the adjusting seat B through a concave-convex structure, a threaded hole is arranged on the concave-convex structure, and a perforation is arranged on the convex-convex structure.
Further improvement: the sliding rod is provided with a fixing piece outside, the first jackscrew is arranged on the fixing piece, the fixing piece is made of a metal material, the handle is made of a nonmetal material, and the fixing piece is fixedly connected with the handle through glue.
Further improvement: the adjusting seat A is provided with a connecting hole, and the front end of the sliding rod is connected with the connecting hole through threads.
The utility model has the advantages that: through the cooperation of adjusting seat A and adjusting seat B for the tuning pole can be under adjusting seat B's drive on adjusting seat A free rotation, when adjusting the rule like this, the user just can be according to the mounted position of peg, adjusts the handle to suitable angle, lets the user have a comfortable operation mode to adjust the rule, thereby reduces because the reason of operation, leads to the axis of peg and the axis of peg jack to appear deviating when rotating, and then has reduced because the harm that the tuning brought to the piano has been ensured the life of piano.
