After adjusting to the position you want to observe, release the connecting handle 305. Because the sliding support block 304 simultaneously drives the squeezing protrusion 3041 to squeeze the spring 3033 on the outer side of the connecting cross bar 3032 when moving, so that the spring 3033 produces elastic deformation. When the spring 3033 loses the squeezing force, the elastic force is released to push the squeezing protrusion 3041 to move, and the squeezing protrusion 3041 drives the sliding support block 304 to move, so that the sliding support block 304 drives the limit plug column 3045 to reset and be inserted into the limit socket 3024 through the slide plate 3043 and the connecting support bar 3044, so that the observer does not need to go in front of the model to observe, thereby improving the observation experience.
