[0020] Through the above solution, the fixing bolt cooperates with the second fastening nut to form a structure for fastening the opening of the first fixing ring.

[0021] Furthermore, outer walls of one end of the eight fixing bolts extending out of the first fixing ring are all threadedly connected with a second fastening nut.

[0022] Through the above solution, the opening and closing of the first fixing ring can be conveniently controlled by threaded fastening.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The scaffold has a wide range of uses. It can be used for construction of ordinary houses as well as for building higher buildings.
