When the aerial platform is moved to the work site, the two support frames 4 on one side are lifted upward to make the two universal wheels 6 arranged thereunder break away from the contact with the ground, and the two handle blocks 20 are pressed toward the opposite sides to drive the limit blocks 15 fixed thereto to move together, compressing the two springs 16. At this time, the two limit blocks 15 will be separated from the engagement with the slots 2 14 provided on the two fixing frames 8, opening the limit, and the fixing rod 7 is pulled downward to drive the two fixing frames 8 fixed thereto to move together. After being pulled to the bottom, the two limit blocks 15 are reset by the elastic force of the two springs 16.

[0028] Working principle:

[0029] When the aerial platform is moved to the working place, the two support frames 4 on one side are lifted upwards to make the two universal wheels 6 arranged thereunder break away from the contact with the ground, and the two handle blocks 20 are pressed toward the opposite sides to drive the limit blocks 15 fixed thereto to move together, compressing the two springs 16. At this time, the two limit blocks 15 will break away from the engagement with the second card slots 14 provided on the two fixing frames 8, opening the limit, and the fixing rod 7 is pulled downwards to drive the two fixing frames 8 fixed thereto to move together. After being pulled to the bottom, the two limit blocks 15 are reset by the elastic force of the two springs 16. At this time, the two limit blocks 15 are respectively engaged with the two second card slots 14 for limit, and the two are in a limit fixed state. After repeating the operation on the other side, the work is completed. The two pairs of fixing frames 8 are in contact with the ground for support. Compared with the traditional universal wheel 6 fixation, the overall support area and stability are improved. The operation is simple and easy to use, meeting the use needs.
