[0030] When in use, the user first pulls the machine head 4 to the right to drive the telescopic frame 101 to stretch, which can emit bright light, improve the visibility and aesthetics of the trackless telescopic door, and serve as a warning and indication. When the wind speed sensor 403 detects that the wind speed exceeds the set value, the electric telescopic rod 501 is started to make its telescopic end drive the supporting foot 502 to drop to the ground, thereby increasing the ground contact area and anti-overturning moment of the trackless telescopic door and improving the stability of the trackless telescopic door. At the same time, the counterweight block 404 can provide additional gravity support, making the trackless telescopic door not easily blown down by the wind, and can achieve increased stability under strong wind conditions. The stability and safety of the trackless telescopic door are improved. The speaker 402 can play the voice prompt of the opening or closing of the telescopic door, which increases the humanization and intelligent functions of the trackless telescopic door. When the machine head 4 needs to be disassembled, the two-way threaded rod 302 is driven to rotate by rotating the rotating handle 303, so that the nut seat 304 makes a reverse vertical movement along the outside of the two-way threaded rod 302, and then the nut seat 304 drives the clamping plate 305 to make a reverse vertical movement, so that the clamping state of the clamping plate 305 and the internal clamping groove of the connecting block 2 can be released, the machine head 4 can be disassembled, and the machine head 4 is easy to repair or replace.
