[0032] Furthermore, the threaded block 23 is slidably connected to the inner wall of the connection box 21, and a hand wheel is fixedly connected to the front end of the driving shaft 27, so that the driving shaft 27 can be rotated by shaking the hand wheel, thereby achieving the purpose of driving.
