[0032] The upper end of the other side of shear structure 1 away from the rotating end can be slidably connected to the bottom end of object table 3, or a guide rail can be arranged on object table 3, so that it can slide in the guide rail, which guarantees the stability of the whole object table 3 installation, and the sliding part 11 below shear structure 1 can also be slidably arranged on the guide rail of support frame 4, and a roller can also be arranged at the end thereof, and the roller and support frame 4 are arranged in parallel, so that shear structure 1 can work normally and guarantee the flexibility of lifting.
[0033] The transmission rod 51 and the stabilizing bar 52 in lifting structure 5 can strengthen the structure strength of shear structure 1, and the stabilizing bar 52 is arranged on shear structure 1 instead of support frame 4, so that lifting structure 5 can move along with shear structure 1 when working, and will not encounter obstacles, and the two ends of lifting structure 5 and the two rods are rotatably connected, the push rod 53 can be retracted by motor driving, so that shear structure 1 can be opened, and object table 3 can be lifted, and the push rod 53 can work to achieve the lifting purpose, which can avoid that the speed of the push rod 53 directly driven is too fast, so that the height adjustment is more convenient, and the push rod 53 can become a state locking structure after height adjustment, which guarantees the stability of the adjusted height, can reduce the operation steps of lifting adjustment, and the overall structure operation is more convenient.
