The lower part of the support frame 1 is fixedly connected with the electric push rod 52, which controls the moving distance and direction of the connecting plate 51 through telescopic movement. This technology is the prior art, and thus will not be described in detail. The output shaft of the electric push rod 52 is fixedly connected to the outer side of the connecting plate 51.
[0035] Further, the upper part of the connecting plate 51 is fixedly connected with the fixed column 53, which cooperates with the sliding groove 55 on the moving plate 54.
