The second telescopic member 5 is shortened and rotated until the positioning ball 6 is aligned with the second positioning groove 31, and then the second telescopic member 5 is extended so that the positioning ball 6 is stuck in the second positioning groove 31, so that the second telescopic member 5 can no longer rotate and can be folded. Holding the handle 7 and turning the device upside down can make each contact plate 4 rotate close to and close to the first telescopic member 1, so that the device is easy to carry after being folded.

[0028] like Figure 1-6As shown, the first telescopic member 1 includes a column 11 and a sliding column 12 sliding in the column 11, the upper end of the sliding column 12 is fixedly connected to the mounting seat 2, the second telescopic member 5 is rotatably connected to the side wall of the column 11, at least two side walls of the column 11 are provided with a plurality of first positioning holes 13 connected to the interior of the column 11 at equal intervals in the vertical direction, one end of the sliding column 12 located in the column 11 is provided with a first sliding groove 14, a first positioning block 15 slides in the first sliding groove 14, a first spring 16 is connected between the first positioning block 15 and the first sliding groove 14, the cross-section of the first positioning block 15 is a right-angled trapezoid with an inclined surface facing upward, the cross-section of the end of the sliding column 12 located in the column 11 is smaller than the cross-section of the end located outside the column 11, at least one-third of the inclined surface of the first positioning block 15 is located in the column 11, and the first positioning block 15 can slide into the first positioning hole 13. After the level gauge is installed, the staff steps on the contact plate 4 and pulls the mounting seat 2 upward, so that the slide post 12 is subjected to an upward pulling force, and the inclined surface of the first positioning block 15 contacts the inner wall of the first positioning hole 13. Due to the reaction force, the first positioning block 15 is completely pushed into the column 11, so that the slide post 12 can be pulled upward all the time, thereby changing the length of the first telescopic member 1, thereby changing the height of the mounting seat 2. After adjusting to a suitable position, the first positioning block 15 is inserted into the first positioning hole 13 at a suitable position, so that the length of the first telescopic member 1 is fixed; if the first telescopic member 1 is to be shortened, the first positioning block 15 is pressed to make it enter the column 11, and the slide post 12 is rotated at a suitable angle, so that the first positioning block 15 is misaligned with the first positioning hole 13, and the slide post 12 can be pressed to shrink the first telescopic member 1. After adjusting to the shortest, the first positioning block 15 is ejected from the first positioning hole 13 at a suitable position by rotating the slide post 12, so that the first telescopic member 1 is quickly retracted and released.

A second positioning block 55 slides in the second sliding groove 54. A second spring 56 is connected between the second positioning block 55 and the second sliding groove 54. The second positioning block 55 has a right-angled trapezoidal cross-section and the inclined surface faces the direction of the positioning ball 6. The second positioning block 55 can slide into the second positioning hole 53. By pulling the positioning ball 6 to make the second rotating rod 52 slide outward from the first rotating rod 51, the inclined surface of the second positioning block 55 contacts the inner wall of the second positioning hole 53 and the second positioning block 55 shrinks into the first rotating rod 51 due to the reaction force, so that the length of the second telescopic member 5 can be quickly changed, and the second positioning block 55 is adjusted to a suitable length so that the second positioning block 55 is rebound into the second positioning hole 53 at a suitable position, and then the positioning ball 6 is inserted into the first positioning groove 41, so that a triangle is formed between the second telescopic member 5, the contact plate 4 and the first telescopic member 1, and the stability of the lifting device is improved.
