The rotating seat 6 is provided in a cylindrical shape, the end surface of the rotating seat 6 is connected with a rotating limiting component, the rotating limiting component includes a limiting seat 11 fixedly connected to the end surface of the rotating seat 6, a planar tooth groove 12 is provided on the end surface of the limiting seat 11, a screw rod 13 is threadedly connected to the end surface of the limiting seat 11, a left clamping sleeve 14 and a right clamping sleeve 15 are respectively sleeved on the screw rod 13, the inclined rod 7 is inserted into the clamping gap between the left clamping sleeve 14 and the right clamping sleeve 15, the end surface of the left clamping sleeve 14 opposite to the planar tooth groove 12 is provided with planar teeth 16 matched with the planar tooth groove 12, a compression spring 17 is sleeved on the screw rod 13 located in the left clamping sleeve 14, one end of the compression spring 17 abuts against the end surface of the limiting seat 11, and the other end of the compression spring 17 abuts against the inner end surface of the left clamping sleeve 14. The free end of the inclined rod 7 is connected with an extension rod 18 through the rotating limiting component. A connecting sleeve 19 with an I-shaped cross section is sleeved on the inner tube 4, a limiting rod 20 is threadedly connected outside the rotating seat 6, and the free end of the limiting rod 20 abuts against the outer surface of the vertical segment of the connecting sleeve 19.
