[0028] Example three
[0029] Reference Figure 7 with Picture 8 As shown, in order to achieve length adjustability, the present invention changes the structure of the scaffold steel pipe. The horizontal rod 2 or the horizontal inclined rod 3 is set to include a fixed section 14 and a screw rod 15 on the left / right / left and right sides of the fixed section 14. The fixed section 14 is provided with internal threads, and the screw 15 is external An external thread adapted to the internal thread of the fixed section 14 is provided. The head end of the screw rod 15 is connected with the fixed section 14 through threads, and the end of the screw rod 15 is connected with the lock head 6. When the lock head 6, the connecting piece 7, the socket base 8 or the fastener 13, and the connecting piece 9 are only installed at the left or right end of the cross bar 2 or the horizontal inclined bar 3, only install the wire on the left or right side of the fixed section 14. The rod 15 is enough...
