The method comprises the steps of firstly controlling the connecting tables 22 on two sides, enabling the connecting tables 22 on two sides to rotate by using a hinge frame 21, enabling the connecting tables 22 on two sides to conduct angle adjustment in a vertical plane, changing the angle of a bridge body 1 in the vertical plane, controlling a large arm 25 to rotate on the bridge body 1 after the angle adjustment in the vertical plane, enabling the large arm 25 to drive a linkage slide rod 26 to rotate, enabling the linkage slide rod 26 to drive a small arm 24 to rotate, enabling the small arm 24 to rotate relative to the connecting tables 22, simultaneously controlling the small arm 24 to slide on a slide rail 23, enabling the small arm 24 and the large arm 25 to conduct adaptive length expansion and contraction change by using the linkage slide rod 26, and therefore enabling the small arm 24 to deflect on the connecting tables 22, and changing the angle of the bridge body 1 in a horizontal plane;
After the angle of the bridge body 1 in the horizontal plane and the vertical plane is adjusted, pressing the large arm 25 to enable the large arm 25 to move downwards, enabling the large arm 25 to drive the linkage slide bar 26 to move downwards, enabling the linkage slide bar 26 to drive the small arm 24 to move downwards, enabling the small arm 24 to press the clamping plate 212 to move downwards, enabling the clamping plate 212 to press the abutting block 211 to move downwards, enabling the abutting block 211 to press the limiting insert 28 in the accommodating through hole 27, enabling the limiting insert 28 to move in the accommodating through hole 27, enabling the limiting insert 28 to be inserted into the inserting hole 210, enabling the limiting insert 28 to limit rotation of the hinge frame 21, limiting angle adjustment of the bridge body 1 in the vertical plane, enabling the limiting insert 28 to move, compressing the spring 29 to shrink, and enabling the spring 29 to provide reset force to reset when reset is needed;
Then, the knob handle 214 is controlled to rotate, the knob handle 214 drives the positioning piece 213 to rotate, the positioning piece 213 is clamped in the clamping plate 212, and the positioning piece 213 is clamped with the clamping plate 212 to limit the deflection movement of the small arm 24 on the sliding rail 23, so that the rotation of the large arm 25 and the small arm 24 relative to the bridge body 1 is restricted, and the angle adjustment of the bridge body 1 in the horizontal plane is limited;
after the big arm 25 moves downwards, the limiting plate 216 is controlled to rotate on the fixed column 215, so that the limiting plate 216 rotates above the big arm 25, and the limiting plate 216 limits the big arm 25 to move upwards, so that a locking effect is formed on the whole steering mechanism 2, and the bridge frame body 1 cannot be changed again after the angle of the bridge frame body 1 in the horizontal plane and the vertical plane is adjusted;
Meanwhile, the fixing frame 32 is controlled to rotate on the extension frame 31, so that the fixing frame 32 is vertically arranged or transversely arranged relative to the bridge frame body 1, a plurality of options are provided for horizontal and vertical selection of a fixing surface under the condition that the self-installation and fixation positions of the cable bridge frame are not changed, and then the locking piece 34 is controlled to rotate into the locking opening 33 so as to limit the fixing frame 32 not to rotate on the extension frame 31, thereby ensuring the stability of the fixing frame 32 in the process of fixedly installing the cable bridge frame.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
