In some embodiments, the reset portion 702 is integrally formed with the second pedal portion 701. The reset portion 702 protrudes in a second direction B opposite to the first direction a with respect to the second pedal portion 701. In some embodiments, the second pedal 701 is connected to the reset portion 702 and has a zigzag shape. The reset portion 702 corresponds to the hinge of the first and second connection members 3 and 4 when the wheel assembly 1 is in a lowered state with respect to the mounting plate 2. The second pedal 701 is stepped on, the restoring member 7 rotates downward, the restoring member 702 impacts the hinge of the first and second connecting members 3 and 4, and the first and second connecting members 3 and 4 rotate to a folded state, thereby enabling the wheel assembly 1 to be converted from a lowered state to a raised state with respect to the mounting plate 2.
Referring to fig. 4, in some embodiments, the lift wheel 100 further includes a locking structure that locks the relative positions of the first and second links 3, 4 when the wheel assembly 1 is in a lowered or raised state relative to the mounting plate 2. Specifically, the locking structure includes a locking post 10 and a first locking portion 11, and the locking post 10 is connected to the second pedal portion 701. Specifically, one end of the connecting post 12 is fixedly connected to the second pedal 701, and the other end of the connecting post 12 is transversely inserted into the locking post 10 and hinged to the locking post 10. And the locking post 10 is located in the second direction B with respect to the rotation shaft 8 so that the locking post 10 moves upward when the second pedal 701 is stepped on. The mounting plate 2 has a second guide cylinder 201, and the locking post 10 is located in the second guide cylinder 201. The second guiding cylinder 201 is provided with a window, and the connecting column 12 extends into the second guiding cylinder 201 through the window to be hinged with the locking column 10. The first locking portion 11 is connected to the first connector 3.

In some embodiments, the first locking portion 11 is integrally formed with the first connecting portion 301. Wherein the locking post 10 is positioned in a first direction a relative to the first locking portion 11 when the wheel assembly 1 is in a raised position relative to the mounting plate 2. When the wheel assembly 1 is in a lowered state relative to the mounting plate 2, the locking post 10 abuts the first locking portion 11. In some embodiments, the mounting block 103 has a limiting slot 1032. The second pedal 701 is stepped on, the reset element 7 rotates downwards, the reset element 702 impacts the hinge joint of the first connecting element 3 and the second connecting element 4, the first connecting element 3 and the second connecting element 4 rotate from an unfolded state to a folded state, the reset element 7 drives the locking column 10 to slide upwards relative to the second guide cylinder 201, and the locking column 10 is in butt joint with the first locking part 11 and is converted into the limiting groove 1032, so that the wheel assembly 1 is converted from a lowered state to a raised state relative to the mounting plate 2. When the wheel assembly 1 is in a raised state with respect to the mounting plate 2, the locking post 10 is positioned in the limiting groove 1032, the spring 6 is in a compressed state, the spring force of the spring 6 tends to push the wheel assembly 1 to move downward, the wheel assembly 1 moves downward to require the second link 4 to rotate in the first direction a, when the second link 4 rotates in the first direction a, the limiting groove 1032 limits the locking post 10 in the limiting groove 1032, so that the second link 4 cannot rotate in the first direction a, so that the wheel assembly 1 cannot move downward, to lock the wheel assembly 1 in a raised condition relative to the mounting plate 2. In some embodiments, the end of the locking post 10 remote from the mounting plate 2 has a notch 1001, the end face of the locking post 10 is beveled, and the beveled surface slopes upward from a first direction a to a second direction B. The first pedal 302 is stepped on, the first connecting part 301 and the second connecting part 4 rotate in the first direction a, so that the wheel assembly 1 moves downwards, the wheel assembly 1 is converted from a lifting state to a descending state relative to the mounting plate 2, the locking post 10 is abutted with the first locking part 11, and the first locking part 11 is positioned at the notch 1001 to lock the relative positions of the first connecting part 3 and the second connecting part 4.
