Other components and connection modes are the same as those of the first embodiment.

The third concrete implementation mode: referring to fig. 2, the present embodiment is further limited to the second embodiment, in which the swing arm 21 includes two vertical plates 211 and two swing arm transverse plates 212; two swing arm diaphragm 212 parallel fixed settings about from top to bottom are between two risers 211, hinge hole one is all seted up at two risers 211 both ends, and four hinge holes one are articulated with connecting axle 24 and frame 4 respectively, be equipped with the clearance between connecting axle 24 and the swing arm diaphragm 212 that is located the below, electronic jar 23 sets up in two swing arm diaphragm 212 below, and the jar head of electronic jar 23 penetrates from the clearance and is articulated with connecting axle 24. The other components and the connection mode are the same as those of the second embodiment.

In this embodiment, the connection structure of the two swing arm transverse plates 212 and the two vertical plates 211 is more stable, and in addition, the swing arm transverse plates 212 play a limiting role in the electric cylinder 23.

In a fourth embodiment, the present embodiment is described with reference to fig. 2, and the present embodiment further defines the third embodiment, and in the present embodiment, the boom 22 includes a sloping plate 223, two diamond plates 221, and two boom transverse plates 222; the inclined plate 223 and the two movable arm transverse plates 222 are fixedly arranged between the two diamond plates 221, the inclined plate 223 is arranged between the two movable arm transverse plates 222, two hinge holes II are formed in two ends of each diamond plate 221, and the four hinge holes II are respectively hinged to the connecting shaft 24 and the supporting legs 3.

In the present embodiment, the two legs 3 are connected to the two oblique sides located at the upper portion of the hexagonal shape. The supporting frame 1 adopting the structure can achieve a more stable effect.

The working process is as follows:

when the supporting legs 3 do not work, the folding device 2 is contracted; when the supporting legs 3 work, the cylinder head of the electric cylinder 23 extends out. The connecting shaft 24 is pushed by the extension of the head of the cylinder, the connecting shaft 24 drives the swing arm 21 and the movable arm 22 to move, and after the swing arm moves to a specified position, the supporting leg 3 is tied to the ground.

When the supporting leg 3 needs to be retracted, the cylinder head of the electric cylinder 23 is retracted, so that the connecting shaft 24 is pulled, the connecting shaft 24 drives the swing arm 21 and the movable arm 22 to move, and finally, the initial retracted state is achieved, and then the movement is completed.

Because the cylinder head of the electric cylinder 23 can be continuously changed, the swing arm 21 can continuously swing within a certain range, and the ground pricking angle of the supporting leg 3 can be adjusted according to the actual ground condition.

The leg 3 is a telescopic leg.
