Traditionally, the use of wood-cover rods is not only troublesome, it is inconvenient to use, it has a small number of turnovers, and it also wastes wood. Now we introduce a kind of iron-based skinned sweat base. It has a simple structure, can be made of leftovers, easy to operate, flexible to adjust when copying, can be used repeatedly for turnover, and can be completely replaced by steel to save wood; poles can be replaced by steel pipes and can be recycled. See Figures 1, 2, 3, 4, and 5. First, the base production 1. With a 50 cm long -50 × 5 flat iron, according to the position of the elevation of 4 -50 × 50 × 5 wing iron, and drill 5 ~ 5.4 holes.
