[0021] like Figure 3 As shown, the positioning device includes two groups of first connection seats 5, multiple groups of first screws 6 and two groups of quick-release pins 7. The two groups of first connection seats 5 are fixedly mounted on the inner wall of the roof 2 by the multiple groups of first screws 6, and the two groups of first connection seats 5 are respectively arranged on the left and right parts of the inner wall of the roof 2. The fixed end of the electric telescopic rod 4 is rotatably mounted on the left first connection seat 5 by the quick-release pin 7, and the movable end of the electric telescopic rod 4 is rotatably mounted on the right first connection seat 5 by the quick-release pin 7.

[0022] In this embodiment, when it is necessary to move the roof 2 upward, the moving end of the electric telescopic rod 4 is separated from the positioning device, and then the electric telescopic rod 4 is rotated downward to a vertical angle so that the moving end of the electric telescopic rod 4 contacts the bottom of the room box 1, and then the moving end of the electric telescopic rod 4 is extended, so that the electric telescopic rod 4 supports the left part of the roof 2 to rise upward. When the left part of the roof 2 is raised and positioned, the moving end of the electric telescopic rod 4 is installed on the positioning device, and then the fixed end of the electric telescopic rod 4 is separated from the positioning device, so that the fixed end of the electric telescopic rod 4 contacts the bottom of the room box 1, and after the moving end of the electric telescopic rod 4 is extended, the electric telescopic rod 4 supports and raises the right part of the roof 2, thereby improving the convenience of the mechanism for lifting the roof 2, reducing the structural complexity of the mechanism, and improving the reliability and portability of use.
