The insertion pipe 2 is slidably inserted into the insertion hole, and a second connecting base 4 is provided at the end of the insertion pipe 2 away from the connecting pipe 1. A plurality of limiting holes are spaced apart along the length of the insertion pipe 2. The limiting member 8 is adjustablely inserted into the side of the connecting pipe 1, with a portion of the limiting member 8 inserted inside the connecting pipe 1. By adjusting the limiting member 8, it is inserted into the corresponding limiting hole to fix the insertion pipe 2 and the connecting pipe 1.

[0032] In this utility model, a preferred embodiment is as follows: during construction, the insertion tube 2 is inserted into the connecting tube 1, and the lengths of the connecting tube 1 and the insertion tube 2 are adjusted so that the sum of the length of the insertion tube 2 protruding from the connecting tube 1 and the length of the connecting tube 1 is adapted to the width of the door and window opening. The limiting member 8 is inserted into the limiting hole to fix the insertion tube 2 and the connecting tube 1.
