The transverse threaded column 5-5 can slide left and right on the two rotary seat sheets 2-10, the two guide rods 2-11 can slide in the two guide rod insertion holes 5-2 respectively, and the transverse threaded column 5-5 and the two guide rods 2-11 limit the upper frame 5 to be in a state that the upper frame can only move left and right but can not rotate; when the hand-screwed nut 5-4 is rotated forward and backward, the transverse threaded column 5-5 can be driven to slide leftwards or rightwards on the two rotating seat sheets 2-10, so that the transverse threaded column 5-5 drives the two groove rods 5-1 to slide leftwards or rightwards, the two groove rods 5-1 respectively drive the two spring sleeve rods 4-3 to slide leftwards or rightwards through the sliding grooves 5-3, and the two spring sleeve rods 4-3 drive the supporting plate body 3-1 to slide leftwards or rightwards when sliding leftwards or rightwards, so that the left and right positions of the supporting plate body 3-1 are adjusted. Since the arc rod 4-1 presses the two grooved rods 5-1, the lower end of the whole supporting plate connecting frame 4 tends to rotate forwards around the hinge shaft of the sleeve ring 2-1 and the rotating block 2-2, the supporting plate body 3-1 also tends to rotate forwards around the hinge shaft of the sleeve ring 2-1 and the rotating block 2-2, the rotating block 2-2 also tends to rotate forwards around the hinge shaft of the sleeve ring 2-1 and the rotating block 2-2, the upper end of the vertical plate 2-4 tends to rotate backwards around the hinge shaft of the sleeve ring 2-1 and the rotating block 2-2, the vertical plate 2-4 pushes the contact cylinder 2-5 backwards, the sliding plate 2-13 slides backwards on the door-shaped frame 2-7 without the adjusting screw 2-9, and the adjusting screw 2-9 is rotated to adjust the front and back position of the adjusting screw 2-9, namely the adjustable supporting plate body 3 1 is formed at an angle to the ground. The plurality of triangular clamping ridges II6-5 are respectively contacted with the plurality of triangular clamping ridges I1-2, the bottom ring 6-1 can be fixed on the base 1-1 under the action of the gravity of the height frame 6, and when the bottom ring 6-1 is rotated, the bottom ring 6-1 drives the internal thread cylinder 6-2 and the vertical threaded column 6-4 to rotate by taking the axis of the fixed cylinder 1-4 as an axis, so that the lantern ring 2-1 is driven to rotate by taking the axis of the fixed cylinder 1-4 as an axis, and the orientation of the supporting plate body 3-1 is changed; the hexagonal rotary head 6-3 can be rotated to drive the vertical threaded column 6-4 to rotate, the vertical threaded column 6-4 can be lifted or lowered when rotating, the vertical threaded column 6-4 is jacked in the jack 2-14 at the lower end of the rear seat 2-12, the height of the lantern ring 2-1 is changed, and therefore the height of the supporting plate body 3-1 is changed.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and that various changes, modifications, additions and substitutions which are within the spirit and scope of the present invention and which may be made by those skilled in the art are also within the scope of the present invention.
