[0032] The clamping assembly comprises a through hole 21, a movable column 22, a check ring 23, a first telescopic spring 24, a movable block 25, a movable plate 26 and a threaded groove 27. The through hole 21 is arranged at the inner periphery of the upper end of the frame body 11. The movable column 22 is slidingly connected to the inner position of the through hole 21. The check ring 23 is fixedly connected to the outer surface of one end of the movable column 22. The first telescopic spring 24 is fixedly connected to the inner side of the check ring 23. The movable block 25 is located at the outer side of the movable column 22. The movable plate 26 is sleeved to the outer side of the upper end of the frame body 11. The threaded groove 27 is arranged on the outer surface of the upper end of the frame body 11.
