The formed annular structure is twisted to form a plurality of torsion portions 131 and two annular portions 132, and the plurality of torsion portions 131 are located between the two annular portions 132; at the same time, the two annular portions 132 are respectively sleeved and matched on the outside of the two guide wheels 15; in addition, the two pulleys 14 are respectively matched with the two annular portions 132, that is, the two annular portions 132 are respectively matched on the outside of the two pulleys 14, and the pulley 14 can move inside the annular portions 132; a first mounting seat 16 is fixedly provided on the pulley 14, and the first mounting seat 16 is used to connect with the bottom of the electric tricycle compartment.

[0047] The shock absorbing mechanism 1 further comprises a circular ring member 17, and the circular ring member 17 has a plurality of Figure 3 As shown, four circular ring members 17 are provided, and the four circular ring members 17 are respectively sleeved on the outside of the four torsion parts 131; each circular ring member 17 is connected to two support tubes 18, and the circular ring member 17 is detachably arranged on the two support tubes 18, and an elastic support member 181 is connected between each support tube 18 and the top surface of the support seat 11, and specifically, the elastic support member 181 adopts a shock-absorbing spring.

[0048] See also Figure 1 , Figure 6 and Figure 7 A right-angle plate 3 is fixedly arranged at the four corners of the supporting base plate 2.
