Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1 and fig. 2 in combination, wherein fig. 1 is a schematic structural view of a preferred embodiment of a sleeve structure of a steep bracket according to the present invention; fig. 2 is a schematic structural view of a first blind hole type patch plate provided by the present invention; fig. 3 is a schematic view of a second blind hole type patch plate structure provided by the present invention. The steeply inclined support sleeve structure includes: the device comprises a side plate 1, two first blind hole type sticking plates 2, two second blind hole type sticking plates 3 and four jacks 4;

the two first blind hole type sticking plates 2 and the two second blind hole type sticking plates 3 are all arranged on the side plate 1, the two first blind hole type sticking plates 2 and the two second blind hole type sticking plates 3 are all provided with blind holes 5, a first group of sleeves and a third group of sleeves are inserted into the two first blind hole type sticking plates 2 from top to bottom, a second group of sleeves are inserted into the two second blind hole type sticking plates 3 from bottom to top, and the bottoms of the four jacks 4 are respectively fixed at the lower parts of the four groups of sleeves, the two first blind hole type sticking plates 2 and the two second blind hole type sticking plates 3.
