The first worm gear 8 is arranged inside the protective shell 12 and is rotatably plugged with the handle 6 through a second bearing. The first worm gear 7 is arranged on the upper side of the first worm gear 8 and meshes with the first worm gear 8. A rotating rod 11 is fixedly plugged on the end face of the first worm gear 7. The front and rear ends of the rotating rod 11 are respectively fixedly connected with the two second worm gears 10. The opposite ends of the two second worm gears 10 are respectively rotatably connected with the front and rear sides of the protective shell 12 through a third bearing. The threads on the surfaces of the two second worm gears 10 are arranged in reverse. The left ends of the two rotating shafts 5 on the left side extend into the protective shell 12 and are respectively meshed with the two second worm gears 9. The two second worm gears 10 are respectively meshed with the two second worm gears 9. A cylinder 13 is movably sleeved on the handle 6.
