A positioning concave plate 3 is sleeved on the movable pad 25. The transverse section of the positioning concave plate 3 is located on the upper side of the movable pad 25. Spring pins 30 are respectively provided at both ends of the positioning concave plate 3. A spring 31 is sleeved on the outer end of the spring pin 30, and an inner pressure plate 32 is provided on the inner end of the spring 31. The insert rod is arranged at the lower end of the inner pressure plate 32.

[0022] The inner end of the movable pad 25 is provided with a clamping pad 4, and the upper end of the clamping pad 4 is openly formed with a plurality of lower semicircular grooves.
