The provision of the second sliding frame 23 can provide stable support for the moving second sliding frame 23, thereby ensuring stable support for the first sliding frame 19.

[0031] Working Principle: This utility model uses a first telescopic rod 5 to drive a movable plate 3 to move up and down on the support frame 1 for height adjustment. The movable plate 3 simultaneously drives the connecting frame 6 for height adjustment. A first motor 8 drives a one-way screw 9 to rotate, which in turn drives a threaded horizontal movable frame 11 for horizontal movement and orientation adjustment.
