[0021] The limiting mechanism 13 includes a first sliding rod 14, the two first sliding rods 14 are respectively fixedly welded on the first sleeve rod 8 and the second sleeve rod 9, a first moving rod 15 is slidably connected to the first sliding rod 14, a tension spring 16 is sleeved on the first sliding rod 14, two ends of the tension spring 16 are respectively fixedly connected to the first moving rod 15 and the first sleeve rod 8, and a limiting rod 17 is fixedly welded on the first moving rod 15.

[0022] On the side walls of the second sleeve rod 9 and the third sleeve rod 10 close to the first moving rod 15, a plurality of equally spaced limiting grooves 18 are formed. The limiting grooves 18 are adapted to the limiting rods 17. The pulling force of the tension spring 16 acting on the first moving rod 15 can drive the limiting rods 17 to move and insert into the corresponding limiting grooves 18, so that the two limiting mechanisms 13 can respectively limit and fix the second sleeve rod 9 and the third sleeve rod 10.

[0023] On the front and rear side walls of the first sleeve rod 8 close to the top, grooves 19 are formed. Second sliding rods 20 are fixedly welded in the grooves 19.
