[0002] The size of the elevator shaft is not uniform according to the function of the building. The traditional shaft protection is usually built with steel pipe fasteners, which are too low and not securely fixed. Or it uses a stereotyped protective door, which is cumbersome to install and requires drilling holes in the structure, which sometimes damages the structure. In addition, due to its large size, it is not conducive to transporting it down from the floor after dismantling, and the turnover is not flexible enough. Summary of the invention

[0017] The beneficial effects are:

[0018] Through the support of the telescopic assembly, the two fixed columns can be fixed at the elevator shaft opening, and the telescopic connecting rod will follow the two fixed columns to expand, thereby serving as a barrier for the elevator shaft opening. The width of the device can be adjusted by the telescopic assembly, so that it can adapt to shaft openings of various sizes. The baffle plate is pressed against the front of the elevator shaft opening, so that the device cannot move into the elevator shaft opening, ensuring effective blocking of the shaft opening. The installation of the device does not require screw fixing, and is easy to disassemble. By adjusting the width of the device to the narrowest, it is easy to turn around and transport;

[0019] By rotating bolt one, bolt one is made to support the inner wall of the wellhead, thus further improving the stability of the device arranged at the elevator wellhead. BRIEF DESCRIPTION OF THE DRAWINGS
