The connecting rod of the rocker 21 passes through the vertical shell 11. A slot block 22 is fixedly installed on the side of the vertical shell 11 close to the cylinder shell 12. The slot block 22 is composed of a plurality of slot rotation arrays. The slot of the slot block 22 is arranged on the side away from the vertical shell 11. The slot block 22 is arranged on the side away from the vertical shell 11. The rotating block 23 is composed of a rotating array of several sliders. The rotating block 23 is limited by the groove opened on the groove block 22. When the rocker 21 is rotated, the slider of the rotating block 23 slides in the groove of the groove block 22 to avoid structural failure caused by the falling of the rotating block 23. A pin is fixedly installed on the side of the rotating block 23 away from the vertical shell 11. The pin is installed at one end where several sliders are close to each other. When the rocker 21 is rotated, the several pins are moved closer or farther away from each other, so as to expand the pipe with different diameters.
