[0022] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] The utility model discloses on the basis of the adjustable construction platform of prior art, the support condition of platform base is improved, through providing a pair of simple support legs of splay shape arrangement on the left and right sides of base, the stable support of base is guaranteed.

[0024] The structure of the adjustable construction platform of prior art is seen from Chinese patent document CN209523447U, and the whole content is incorporated herein for reference.

[0025] The hydraulic support leg structure and control of prior art engineering vehicle are complex, and are not suitable for being used in the house building construction occasion of the utility model, therefore, the simple support leg structure is developed.

[0026] Combined with reference Figures 1 to 7 The left and right sides of the base 1 of the auxiliary lifting platform are symmetrically provided with two pairs of support legs.

[0027] The base 1 is welded with two support seats 2 and 22 close to each other on one side, the support seat 2 is pivotally connected with a first rotating arm 3, and the support seat 22 is pivotally connected with a second rotating arm 4.

[0028] The first rotating arm 3 and the second rotating arm 4 are provided with threaded holes and guide holes located on both sides of the threaded holes close to the terminal ends.

[0029] The threaded holes are connected with screw rods 7, the guide holes are provided with guide columns 6, and the top of the guide column 6 is welded with a limiting plate 15.

[0030] The bottom of the horizontal plate 8 is welded with a plurality of symmetrically arranged support columns 9, and the bottom of the support column 9 is fixedly installed with a non-slip shoe 10.

[0031] The clamping plate 5 is located above the first rotating arm 3 and the second rotating arm 4, one end of the clamping plate 5 is provided with a guide rod 11, and the other end is provided with a clamping column 13.

[0032] The first rotating arm 3 is provided with a guide sleeve 17, the guide rod 11 is inserted and matched with the guide sleeve 17, the lower end of the guide rod 11 is provided with a spring seat 19, the spring 12 is sleeved on the guide rod 11 and the lower end thereof abuts against the spring seat 19, the upper end of the spring 12 abuts against the first rotating arm 3, and the clamping plate 5 is elastically and floatingly connected with the first rotating arm 3.

[0033] The second rotating arm 4 is respectively provided with a first positioning hole 20 and a second positioning hole 21, and each is provided with a guide sleeve 18, and the clamping column 13 can be selectively inserted and matched with the guide sleeve 18 in the first positioning hole or the second positioning hole.
