The base is fixedly arranged, the pin shaft 3 can be inserted into or taken out from the base, and the pin shaft 3 is connected with the hanging ring 15 at the lower end of the steel wire rope 2. The length of the wire rope 2 is determined according to the size of the roaster, and the wire rope 2 can protect the roaster and prevent the roaster from falling down in a connected and straightened state.
As shown in fig. 1, the base comprises a steel base floor 6 and at least two base plates arranged on the steel base floor 6, and shaft holes for the pin shafts 3 to pass through are arranged on the base plates.
As shown in fig. 1, in the present embodiment, two base plates are provided, which are a first base plate 4 and a second base plate 5, respectively, a first shaft hole 8 is provided in the first base plate 4, and a second shaft hole 9 is provided in the second base plate 5. The first base plate 4 and the second base plate 5 are vertically arranged on the steel base floor 6, the first base plate 4 and the second base plate 5 are steel plates, the first shaft hole 8 is a round hole formed in the upper end of the first base plate 4, the second shaft hole 9 is a round hole formed in the upper end of the second base plate 5, the first shaft hole 8 and the second shaft hole 9 are coaxially arranged, and the diameters of the first shaft hole 8 and the second shaft hole 9 are slightly larger than the outer diameter of the pin shaft 3.
