Arc joint ring 29 the joint mouth has, the joint mouth of a plurality of arc joint rings 29 all rotates the direction setting towards anticlockwise (first erection column 10 clockwise turning and the cooperation of second erection column 11), promptly with spacing draw-in groove 15's opening direction inconsistent, when avoiding rotatory insertion section 2 to make first installation department and second installation department cooperation process, first erection column 10 just breaks away from the cooperation with arc joint ring 29.
It should be noted that the above embodiments are merely representative examples of the present invention. Many variations of the utility model are possible. Any simple modification, equivalent change and modification of the above embodiments according to the spirit of the present invention should be considered to be within the protection scope of the present invention.
