Multiple positioning holes are equidistantly opened on the upper end of the positioning frame 3. A clamping mechanism is installed in the positioning holes, and a positioning mechanism is installed on the upper end of the clamping mechanism. The support column 1 and the support plate 2 facilitate the support and fixation of the positioning frame 3. The limiting plate has fixing bolt holes evenly spaced in the vertical direction, and the limiting plate and the positioning frame 3 are fixed by hexagonal bolts 4. The limiting plate and the hexagonal bolts 4 facilitate the prevention of movement of the positioning frame 3. A vertical rod 6 is installed in the positioning hole in the vertical direction. A second threaded rod 12 is fixed to the lower end of the vertical rod 6. A sliding rod 17 is fixed to the lower end of the second threaded rod 12. A circular base plate 16 is fixed to the lower end of the sliding rod 17. The vertical rod 6 and the positioning hole facilitate the fixing of the vertical rod 6 in the positioning hole.

[0021] In this utility model, the upper end of the upright rod 6 is horizontally fixed to one end of the fixed rod 7, and the other end of the fixed rod 7 is vertically provided with a positioning threaded hole. The positioning mechanism is easily installed through the fixed rod 7 and the positioning threaded hole. The clamping mechanism includes an internal threaded ring 11 sleeved on the outer side of the upper end of the second threaded rod 12. Multiple arc-shaped grooves are vertically and equidistantly provided on the outer side of the internal threaded ring 11, and the internal threaded ring 11 is threadedly connected to the second threaded rod 12. A fixed post 13 is circumferentially and equidistantly fixed to the lower end of the internal threaded ring 11. A movable ring 14 is fixed to the lower end of the fixed post 13.
