The rotation of the bidirectional screw rod 21 adjusts the position of the fixed plate 22 on the bidirectional screw rod 21 through the threaded member 23, thereby controlling the distance between the contact member 20 and the rotating column 12 and the length of the telescopic rod 19, and further adjusting the relative moving distance of the mounting frame 7 when the contact member 20 rotates to the horizontal state, so as to facilitate the user to adjust the degree of the telescopic rod 19 according to the distance, so that the positioning mold 5 can be applicable to cylindrical sheet metal raw materials of multiple different sizes.

[0033] The present invention can only make the active disk 24 rotate continuously.
