[0018] See also Figure 5 The locking assembly 6 includes an insert rod 61 and a sleeve rod 62. The ends of the insert rod 61 and the sleeve rod 62 extend outside the surface of the connecting rod 5. The inner cavity of the sleeve rod 62 is movably sleeved with a spring 63, and the insert rod 61 and the sleeve rod 62 are both slidably sleeved in the inner cavity of the connecting rod 5. One end of the sleeve rod 62 is inserted in the inner cavity of the insert rod 61, and the spring 63 respectively abuts against the inner wall of the connecting rod 5 and one end of the insert rod 61. The surface of the insert rod 61 and the end of the sleeve rod 62 have the same diameter and are mutually engaged with the limiting groove 9. The number of the limiting grooves 9 is one symmetrical on each of the three sides and one in the middle. By changing the engagement of the three limiting grooves 9 with the locking assembly 6, the storage of the support ladder and the use of the left and right sides of the car can be facilitated. In addition, pressing the insert rod 61 can drive the sleeve rod 62 to move, so that the surface of the insert rod 61 and the end of the sleeve rod 62 leave the limiting groove 9. After losing the limit, the connecting rod 5 can rotate in the inner cavity of the rotating member 8.

[0019] During installation, first insert the end of the supporting ladder into the inner cavity of the connecting end 2. Through holes are provided on the surfaces of the end of the supporting ladder and the connecting end 2. Therefore, the connection is completed by passing the locating pin through the through hole through the connecting end 2 and the end of the supporting ladder.
