The two lifting columns 4 are respectively inserted and installed in the corresponding columns 1, and the connecting beam C13 is also inserted and installed between the two slide grooves 11, and the plug hole B12 at the bottom of the lifting column 4 is inserted and installed on the outside of the corresponding guide rod 10. The guide rod 10 located between the bottom of the column 1 and the lifting column 4 is sleeved with a compression spring A15, and the two lifting columns 4 are respectively inserted and installed in the corresponding columns 1, and the lifting column 4 is supported by the compression spring A15, so that the lifting process of the lifting column 4 becomes more stable;

[0022] like Figure 2-Figure 4As shown, a bearing seat 16 is fixedly installed at the center position of the lower end of the connecting beam A2, and the bearing seat 16 is connected with the insertion hole A5 channel. The connecting beam A2 located at the outer position of the bearing seat 16 is provided with a plurality of tooth grooves 17. The lower end of the adjusting screw 7 passes through the insertion hole A5 and is rotatably installed in the bearing seat 16, while the upper end of the adjusting screw 7 is threadedly connected in the screw hole 14. A mounting hole 18 is provided in the wheel ring of the hand wheel 8. Through the setting of the bearing seat 16, the lower end of the adjusting screw 7 can be limitedly rotated in the bearing seat 16, so that the upper end of the adjusting screw 7 can be rotated in the screw hole 14 to control the lifting and lowering of the connecting beam C13;

[0023] like Figure 2-Figure 4 As shown, the outer corners of the limit rod 9 are all arc-shaped and have threads, and the extended lines of the threads on the outer sides of the four arc edges are complete spiral threads. The limit rod 9 is inserted and installed in the mounting hole 18, and the limit rod 9 located above the handwheel 8 is threadedly connected with a nut 19, and the limit rod 9 located between the nut 19 and the handwheel 8 is provided with a compression spring B22.

At this time, the hand wheel 8 can be driven to rotate by the crank 21, and the hand wheel 8 drives the adjusting screw 7 to rotate. As a result, the lower end of the adjusting screw 7 is limitedly rotated in the bearing seat 16, and at the same time, the upper end of the adjusting screw 7 is also rotated in the screw hole 14 of the connecting beam C13, so that the control The connecting beam C13 moves up and down, so the connecting beam C13 synchronously drives the two lifting columns 4 to move up and down in the corresponding column 1, and uses the compression spring A15 to provide buffer stability for the up and down movement of the lifting columns 4. When the height adjustment of the two lifting columns 4 and the connecting beam B6 is completed, it can be seen that the crank 21 is loosened, so that the nut 19 is pushed up by the rebound force of the compression spring B22, so that the nut 19 drives the limiting rod 9 to move up in the mounting hole 18, so that the limiting tooth 20 is inserted into the corresponding tooth groove 17 to limit the hand wheel 8, and the axial movement of the adjusting screw 7 can be limited.
