In this embodiment, the number of the adjusting devices 4 is four, the four adjusting devices 4 are respectively located at the left side and the right side of the upper support plate 1 and the lower support plate 3, that is, two adjusting devices 4 are arranged at one side, and the relative deflection between the upper support plate 1 and the lower support plate 3 is realized through the height difference of the adjusting devices 4 at the two sides.
In this embodiment, the telescopic device includes an upper connecting screw rod 431, a lower connecting screw rod 432 and a connecting sleeve 44, an upper threaded hole is provided at the upper end of the connecting sleeve 44, a lower threaded hole is provided at the lower end of the connecting sleeve 44, and the screw thread turning directions of the upper connecting screw rod 431 and the lower connecting screw rod 432 are opposite;
the upper end of the upper connecting screw rod 431 penetrates through a connecting through hole of the upper swing groove, the diameter of the upper connecting screw rod 431 is smaller than the inner diameter of the connecting through hole, the upper end of the upper connecting screw rod 431 is fixed on the upper swing block 461, and the lower end of the upper connecting screw rod 431 is in threaded connection with an upper threaded hole;
the lower end of the lower connecting screw rod 432 penetrates through the connecting through hole of the lower swing groove, the diameter of the lower connecting screw rod 432 is smaller than the inner diameter of the connecting through hole, the lower end of the lower connecting screw rod 432 is fixed on the lower swing block 462, and the upper end of the lower connecting screw rod 432 is in threaded connection with the lower threaded hole.
When the connecting device is used, only the connecting sleeve 44 needs to be rotated, and the upper connecting screw rod 431 and the lower connecting screw rod 432 can not be rotated all the time because the upper swinging block 461 and the lower swinging block 462 can not be rotated, and at the moment, the relative extension or shortening of the upper connecting screw rod 431 and the lower connecting screw rod 432 can be realized under the rotation of the connecting sleeve 44.

In this embodiment, the lower end of the upper swing block 461 may be an arc-shaped structure, but from the top view in fig. 2, the cross section of the upper end of the upper swing block 461 is a rectangular structure or other special-shaped structures, as long as it is not a circle, but the upper end structure of the upper swing groove is matched with the upper end structure of the upper swing block 461, in this case, when the connecting sleeve 44 is rotated, the upper end of the upper swing block 461 abuts against the upper end of the upper swing groove to be clamped, so that the upper connecting screw rod 431 cannot rotate together with the connecting sleeve 44; alternatively, a plurality of irregular arc-shaped rails may be disposed at the bottom of the upper swing groove, so as to limit the upper swing block 461 to slide only left and right on a fixed arc-shaped rail without sufficient space for moving to the adjacent arc-shaped rail. Of course, other connection structures can be used as long as the upper swing block 461 can swing left and right in the upper swing groove and cannot rotate relatively. In addition, the inner diameter of the connecting through hole is larger than the diameters of the upper connecting screw rod 431 and the lower connecting screw rod 432 as much as possible on the premise of ensuring the overall strength, so that the upper connecting screw rod 431 and the lower connecting screw rod 432 have gaps in the connecting through hole respectively, and the phenomenon that the upper swing groove or the lower swing groove is abutted against the upper connecting screw rod 431 or the lower connecting screw rod 432 when swinging to cause clamping is prevented.
In the present embodiment, a turning insertion hole 45 is provided at the center of the side wall of the connection sleeve 44, and the turning insertion hole 45 penetrates the connection sleeve 44 in the diameter direction of the connection sleeve 44. When the connecting sleeve 44 needs to be rotated, a circular steel bar or other circular rod type devices only need to be found from the installation site, the circular steel bar penetrates through the steering insertion hole 45, a worker only needs to rotate the circular steel bar to drive the connecting sleeve 44 to rotate, the connecting sleeve 44 can be driven to rotate only through the circular steel bar, and materials can be conveniently taken in place. It should be noted that the inner circular steel bar inserted into the connecting sleeve 44 does not contact the upper connecting screw 431 or the lower connecting screw 432.
In the present embodiment, there are a plurality of steering insertion holes 45, and the steering insertion holes 45 are uniformly distributed on the side wall of the connecting sleeve 44. The reason why the plurality of steering insertion holes 45 are provided is that, in an actual operation process, an installation environment space of the support main body is narrow, and after the circular steel bar is inserted, a worker may not rotate the connecting sleeve 44 by a complete circle when rotating the connecting sleeve. At this time, the round steel bar can be taken out and inserted into another turning insertion hole 45 to perform a certain range of turning, and the turning is repeated for a plurality of times until the upper connecting screw rod 431 and the lower connecting screw rod 432 are extended or shortened to a desired length.
In this embodiment, the upper connecting screw 431 and the lower connecting screw 432 are both connected with a locking nut 47 through threads, and after the telescopic lengths of the upper connecting screw 431 and the lower connecting screw 432 are adjusted, the locking nut 47 is tightened, so as to fasten the upper connecting screw 431 and the lower connecting screw 432.
In this embodiment, the upper connection plate 411 is fixed on the upper support plate 1 by a plurality of upper fixing screws 421, specifically two or four, and the plurality of upper fixing screws 421 are uniformly distributed on the left and right sides of the upper connection plate 411, so as to improve the fixing effect of the upper connection plate 411;
similarly, the lower connecting plate 412 is fixed to the lower support plate 3 by a plurality of lower fixing screws 422, specifically two or four lower fixing screws 422, and the plurality of lower fixing screws 422 are uniformly distributed on the left and right sides of the lower connecting plate 412, so that the fixing effect of the lower connecting plate 412 is improved.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the utility model.
