The extending part 62 is provided with a plurality of reinforcing parts 63, the reinforcing parts 63 are triangular reinforcing ribs, the reinforcing parts 63 are fixedly connected with the extending part 62 and tightly abut against one side plate surface of the connecting part 6 far away from the track plate 10, and therefore the possibility that the connecting part 6 and the extending part 62 are bent relatively due to load is reduced. The contact area between the connecting piece 6 and the circumferential side wall of the track plate 10 is expanded through the extension piece 62, so that the possibility that the contact area between the connecting piece 6 and the circumferential side wall of the track plate 10 is damaged when the connecting piece 6 drives the track plate 10, water accumulation and wind erosion are accelerated, and the service life of the track plate 10 is influenced is reduced.
The implementation principle of the embodiment 2 is as follows: through addding vacuum chuck 141, promoted base 1 and track seat 20 positioning connection's stability, reduced the influence of device drunkenness to the adjustment accuracy, simultaneously through universal joint 67, adjust the setting of pole 66 to and adjust pole 66 and Z to the articulated with connecting piece 6 respectively of slider 43, thereby turn to regulation head 68 through the drive, make adjust pole 66 flexible and promote or stimulate connecting piece 6 to take place to deflect, and then adjust track board 10 horizontal rotation position. Meanwhile, the connecting piece 61 is arranged through the connecting piece 6, the position of the fixing bolt 613 and the connecting plate can slide in a certain range, the adaptability of the hole distance between the connecting plate and the track plate 10 is improved, and after the fixing bolt 613 and the bolt hole are screwed, the fixing bolt 613 compresses the connecting piece 61, so that the sliding piece 611 is abutted against the groove wall of the sliding groove 65, and the connecting piece 61 and the connecting piece 6 are positioned.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
