Specific embodiment
In order to clarify the technical characteristics of the invention, being illustrated below by specific embodiment to this programme.
As shown in Figure 1, the utility model include I section 1 of anchor pole, III section 2 of anchor pole and be located at I section 1 of anchor pole and III section 2 of anchor pole
Between II section 3 of at least one anchor pole, with spiral ribs protrusion on I section 1 of anchor pole, II section 3 of anchor pole and III section 2 of anchor pole of outer wall
5, I section 1 of anchor pole, II section 3 of anchor pole and III section 2 of anchor pole of inside are equipped with lumen 6.The affixed drill bit 7 in I section 1 of anchor pole wherein one end,
Drill bit 7 is equipped with the notch 8 communicated with I section of 1 interior lumen 6 of anchor pole, and the other end that I section 1 of anchor pole passes through connector sleeve 4 and anchor pole II
One end connection of section 3, the other end that II section 3 of anchor pole are connect by connector sleeve 4 with III section 2 of anchor pole one end, III section 2 of anchor pole another
One end is equipped with external screw thread, and pallet 9 is cased on external screw thread, and pallet 9 is fixed by the nut 10 being connected on screw thread.The knot of pallet 9
Structure is existing structure, and the mode of 10 fixed tray 9 of nut is existing fixed form.
