[0018] When the position of the I-beam needs to be fixed, the mounting frame is slid to make the mounting frame correspond to the position of the slot opened on the surface of the support column, and then the I-beam is manually slid into the inside of the slot, and the connecting frame is pressed downward to drive the slide plate to move synchronously, so that the slide plate contacts the curved surface opened at the top of the right side of the slider, thereby pushing the slider to move in the direction of the I-beam. At the same time, because the upper and lower ends of the left side of the slider are provided with inclined surfaces and one end of the card block is provided with an inclined surface, the movement of the slider drives the card block to move, so that the card block slides into the inside of the card slot. At this time, the pin slides into the inside of the socket under the elastic force of spring three, and the position of the connecting frame is fixed, thereby achieving the fixation of the position of the I-beam.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By using the clamping parts and the fixing parts together, after the staff slides the I-beam into the slot, they only need to press the connecting frame to make the pin snap into the inside of the socket under the elastic force of the spring three, thereby achieving the fixing effect of the I-beam.
