When the rotating column 5 rotates, the shift fork passes between the center position of the U-shaped high-frequency heating coil 4 and the two water guide frames 9.

[0028] The fixing mechanism includes a top plate 13 corresponding to the mounting groove 6 one by one, the top plate 13 is slidably connected to the inner wall of the mounting groove 6, a spring 12 is installed at one end of the top plate 13 close to the center of the rotating column 5, and the end of the spring 12 away from the top plate 13 is installed at the bottom of the mounting groove 6, a through hole 15 is opened on one of the side walls of the mounting groove 6, a card plate 14 for blocking, squeezing and fixing the connecting part of the shift fork is slidably connected on the inner wall of the through hole 15, a fixing plate 16 is installed through the through hole 15 at one end of the card plate 14 away from the mounting groove 6, a tension spring 18 for pulling the fixing plate 16 close to the rotating column 5 is installed on the side wall of the fixing plate 16 close to the rotating column 5, the end of the tension spring 18 away from the fixing plate 16 is installed on the end surface of the rotating column 5, and a pull ring 17 is installed at one end of the fixing plate 16 away from the rotating column 5 for facilitating the staff to pull the fixing plate 16.

[0029] When fixing the shift fork, the staff pulls the pull ring 17, the pull ring 17 drives the fixed plate 16 to move, the fixed plate 16 drives the card plate 14 to move, and stretches the tension spring 18, so that the card plate 14 opens the mounting groove 6, and then the staff inserts the connecting part of the shift fork into the inside of the mounting groove 6, the shift fork pushes the top plate 13 to move, the top plate 13 compresses the spring 12, and then releases the pull ring 17.
