[0027] The clamp 4 in this embodiment includes a clamp body 41, a clamp sleeve 42, a locking sleeve 43 and a locking spring piece 44. The locking sleeve 43 is installed in the clamp sleeve 42, and the locking sleeve 43 is threadedly connected to the clamp sleeve 42. The clamp sleeve 42 is sleeved outside the universal rod 34, and the clamp sleeve 42 is rotatably installed on the universal rod 34. The locking spring piece 44 is fixed on the universal rod 34, and the locking spring piece 44 cooperates with the locking sleeve 43. A positioning piece 45 is fixed on the universal rod 34, and the positioning piece 45 is located on the inner side of the locking spring piece 44. The locking spring piece 44 is provided with a spring piece protrusion 46, and the spring piece protrusion 46 contacts the locking sleeve 43.
