[0037] In the present utility model, by directly arranging the moving probe 5 on the guide pin 7 of the pawl 8, the position of the pawl 8 can be directly obtained by detecting the position of the moving probe 5 through the radial position detection sensor 4. Then, combined with the cooperation of the controller 10 and the driving device 3, the automatic adjustment of the opening and closing size of the pawl 8 is realized, avoiding quality problems caused by manual adjustment errors, and there is no need to modify and process other components of the vulcanizer.
