[0010] Furthermore, it also includes a balancing component that ensures that the column can always be in a balanced position. The balancing component includes multiple groups of telescopic rods equidistantly installed on the upper surface of the bracket and a movable plate arranged inside the second cavity. Multiple groups of straight grooves are opened inside the movable plate, and a slide groove is opened on the upper surface of the movable plate. The slide groove is slidably connected to an elastic head, and a guide rod is inserted into the straight groove. The ends of the two groups of guide rods on the same side are fixedly connected to the same group of connecting plates, and the connecting plates are slidably matched with the limit grooves through sliders.

[0011] Furthermore, a ball is fixedly mounted on the upper end of the telescopic rod, and the ball is movably connected to the lower surface of the ring, and the lower end of the telescopic rod is connected to an air intake pipe, and the air intake pipe is connected to two groups of delivery pipes, and the delivery pipes are connected to the elastic hose.
