One of the connecting cylinders 61 is connected to the telescopic rod 212. At least one connecting cylinder 61 is slidably connected to the connecting rod 62 so that the two bending plates 221 are laterally moved closer to or farther away from each other. In the present embodiment, the two connecting cylinders 61 are slidably connected to the connecting rod 62, respectively.

In other embodiments, the connecting tube 61 near the telescopic rod 212 may be fixedly connected with the connecting rod 62, and the connecting tube 61 far from the telescopic rod 212 is slidably connected with the connecting rod 62; alternatively, the connecting cylinder 61 close to the telescopic rod 212 can be slidably connected with the connecting rod 62, and the connecting cylinder 61 far from the telescopic rod 212 is fixedly connected with the connecting rod 62, and the specific arrangement is determined according to the requirement.
