[0025] It should be noted that the rotating shaft 7 is connected to the mounting shell 6 through a bearing, and the lower end of the rotating shaft 7 is fixedly connected to a handwheel 8, which facilitates the rotation adjustment of the rotating shaft 7. At the same time, the threads on the screw rods 12 at the left and right ends of the connecting shaft 11 are set in opposite directions to each other, and the end of the screw rod 12 away from the connecting shaft 11 is connected to the mounting shell 6 through a bearing.
