Fig. 1 is structural representation of the present utility model;
Fig. 2 is fixedly mounting and the lifting mounting connection diagram of Fig. 1;
Fig. 3 is the schematic diagram of lifting mounting in decline state;
Fig. 4 is the schematic diagram of lifting mounting in propradation.
In figure, mark is as follows: connecting rod 1, lifting mounting 2, hydraulic cylinder 3, fixedly mounting 4, coupling spindle 5, copper bush 6.
The specific embodiment
The utility model is by fixedly mounting 4, lifting mounting 2, connecting rod 1, coupling spindle 5, hydraulic cylinder 3 form.
In figure, show, fixedly mounting 4 is arranged on basis above, and lifting mounting 2 is positioned at the fixedly top of mounting 4, and fixedly mounting 4 is connected by connecting rod 1, coupling spindle 5 with lifting mounting 2, and the mounting 2 of lifting simultaneously carries out lifting by hydraulic cylinder 3.
