";

[0004] When the above device is in use, a hydraulic cylinder and a telescopic support rod are installed on the device, and the hydraulic cylinder and the telescopic support rod move synchronously. A support arm and a suction cup are installed on the device, and the suction cup fixes the entire device. Although this device is telescopic and easy to fix, when this device is used on a construction site, due to the uneven ground and the presence of relatively sharp substances, the universal wheel is easily damaged when it is on the ground for a long time, thereby reducing the service life of the universal wheel, so it needs to be improved by the staff. Utility Model Content

[0016] 1. The utility model provides a base device of a pull-out safety warning sign. The power is connected to the electric telescopic rod, so that the electric telescopic rod works and retracts into the support block. Then the support block is rotated so that the universal wheel is at the top of the support block, so that the universal wheel is separated from the ground, and the friction between the universal wheel and sharp objects on the ground is prevented to cause wear. The fixed block is pressed to disengage the connecting arm from the fixed position, so that the support block can be pushed to the inner wall of the support base, thereby reducing the volume of the support base, increasing the aesthetics of the device, and effectively protecting the universal wheel. When the universal wheel is in use, the bottom of the support base is slightly higher than the bottom of the universal wheel, so that the inclination angle of the support base is small when the universal wheel is retracted, which is convenient for retracting the universal wheel, thereby achieving the effect of protecting the universal wheel.

[0017] 2. The utility model provides a base device of a pull-out safety warning sign. The warning sign is inserted into a limit frame and fixed, and then the warning sign is inserted into a display frame, so that the display frame can effectively protect the warning sign. At the same time, the first fixing knob and the second fixing knob are rotated and separated from the limit frame, so that the warning sign can be separated from the limit frame, so that the device can display different warning signs, and then can be reused in different locations, thereby achieving the effect of conveniently protecting the warning sign.
