Preferably, the first moving wheel 15 comprises a universal wheel or a rudder wheel; and / or, the second moving wheel 16 comprises a universal wheel or a rudder wheel. For example, the first moving wheel 15 can be all selected to be a universal wheel, and the second moving wheel 16 can be all selected to be a universal wheel. Or, the first moving wheel 15 can be all selected to be a rudder wheel, and the second moving wheel 16 can be all selected to be a rudder wheel. Or, the first moving wheel 15 can be all selected to be a universal wheel, and the second moving wheel 16 can be all selected to be a rudder wheel.

The upper surface of the support platform 21 is provided with an elastic limiting piece 23 near the top end. The elastic limiting piece 23 can include a diagonal brace, and the diagonal brace is provided with a torsion spring. When the valve body passes through, the diagonal brace is pressed down.
