The end of the sliding card plate 473 away from the cross fixing frame 47 penetrates into the interior of the fixed card groove. The inner wall of the telescopic slide 472 is provided with a guide slide groove 474 on both opposite surfaces close to the oblique slide groove 48. The outer surface of the sliding card plate 473 is fixedly connected with a sliding block 475 on both opposite surfaces close to the guide slide groove 474. The sliding block 475 is slidably connected to the interior of the guide slide groove 474 and penetrates into the interior of the oblique slide groove 48.

[0027] When installing the transverse roller 4, the plug-in column 44 is inserted into the inner side of the circular slide 6, and by rotating the knob 45, the transmission screw 46 can cooperate with the thread of the threaded hole 471 to drive the cross fixing frame 47 to slide inside the cross slide groove, and the sliding block 475 can slide inside the oblique slide groove 48, so that the sliding block 475 can slide along the guide slide groove 474, and the sliding card plate 473 can slide out of the inside of the telescopic slide groove 472, and can be stuck in the fixed card groove on the inner side of the circular slide 6, so that the installation and fixation of the transverse roller 4 can be realized.

At the same time, through the setting of the bearing 42, the rotation of the rotating wheel 43 can be facilitated. When in use, the vibration of the transverse roller 4 can make the circular slide plate 6 slide, so that the sliding column 62 can drive the sliding push plate 63 to squeeze the first spring 64, and the sliding push plate 63 can also push the squeezing column 66 to squeeze the second spring 67 through the pushing rod 65, so that the transverse roller 4 can be shock-absorbing and buffered, and the elevator can be shock-absorbing and buffered, making the use of the elevator roller guide shoe more convenient.
