When in normal use, the lock rod 14 is inserted into the lock hole 17 of the side wall of the sliding column 3, which is close to the mounting plate 1, and at the moment, the universal wheel can turn normally. When the universal wheel is required to be oriented, the pull plate 15 is pulled, the lock rod 14 is separated from the lock hole 17, the anti-falling plate 18 is completely arranged in the accommodating groove 19, the sliding column 3 is pushed to slide upwards along the sleeve 2, after the clamping block 9 at the top of the outer ring of the bearing 4 is clamped with the clamping groove 8 at the bottom of the clamping disc 7, the pull plate 15 is loosened, under the action of the elastic force of the second spring 16, the lock rod 14 is inserted back, and at the moment, the lock rod 14 is inserted into the lock hole 17 of the side wall of the sliding column 3 far away from the mounting plate 1, so that orientation is completed. By providing the drop-off preventing plate 18, the lock lever 14 can be prevented from being pulled out of the side wall of the sleeve 2 by excessive force, and simultaneously, when the pulling plate 15 is pulled, the drop-off preventing plate 18 is completely pulled into the accommodating groove 19, so that the influence on the movement of the slide column 3 caused by the fact that the drop-off preventing plate 18 protrudes out of the inner wall of the sleeve 2 can be reduced. By providing the second spring 16, the lock lever 14 can be automatically sprung back, making the operation more convenient.

Referring to fig. 3, a pull wire 20 is welded and fixed at a central position of one side of the pull plate 15 far away from the sleeve 2, in this embodiment, the pull wire 20 is made of high-carbon steel wires, a circular pressing plate 21 is arranged at one end of the pull wire 20 far away from the pull plate 15, the pressing plate 21 is fixed at a central position of the bottom surface of the draw-bar box through a fixed spring, and the pull plate 15 is fixedly connected with the side wall of the pressing plate 21. The lateral wall of clamp plate 21 has still linked firmly the stay 20 of other orientable universal wheels of draw-bar box bottom, for pressing down conveniently, clamp plate 21 top surface welded fastening has running-board 22, and running-board 22 stiff end is the ring form, and its external diameter equals with clamp plate 21 diameter, and fixed spring passes running-board 22 inner ring and clamp plate 21 to be fixed, and running-board 22 is kept away from the one end of clamp plate 21 and is the strip and with draw-bar box parallel and level.

The implementation principle of the orientable draw-bar box universal wheel is as follows: when the universal wheels of the draw-bar box need to be oriented, the pedal 22 is stepped on, the locking assemblies of all the universal wheels at the bottom of the draw-bar box are opened, the draw-bar box is pressed downwards, the dust guard 23 is abutted against the clamping disc 7, the draw-bar box is slightly rotated, the clamping block 9 is clamped with the clamping groove 8, the pedal 22 is loosened, and the orientation of the universal wheels is completed.
