An adjusting sleeve 8 is sleeved on the outside of the fixing rod b9. A limiting rod 6 is provided inside the adjusting sleeve 8 to limit the position of the motorcycle front. An adjusting bolt 7 is provided between the adjusting sleeve 8 and the limiting rod 6 to limit the position of one end of the limiting rod 6. A fixing buckle a4 is provided between the fixing rod a5 and the fixing rod b9 to limit the position of the limiting rod 6.

[0051] When pre-limiting the front position of the vehicle using the limiting rod 6, first remove the adjusting bolt 7, and adjust the position of the originally vertically placed limiting rod 6 inside the adjusting sleeve 8 so that the limiting rod 6 is placed horizontally on the upper side of the vehicle pedal. Then, attach one end of the limiting rod 6 to the fixing rod a5, and re-fix the other end inside the adjusting sleeve 8 with the adjusting bolt 7, attaching it to the side of the fixing rod a5, and fix it with the fixing buckle a4. One end of the limiting rod 6 is provided with a slot for the fixing buckle a4 to engage. The fixing buckle a4 and fixing buckle b24 are provided with a fixing plate, a fixing ring, a movable handle, and a locking ring from top to bottom. The two fixing plates are fixed to the limiting rod 6 and the positioning rod 10 respectively. When fixing the fixing rod a5 and the limiting rod 6 to the rear frame 11 and the positioning rod 10, first push the movable handle to loosen the fixing ring, and then fix the ring. The handle is fitted onto the corresponding fixed buckle plate, and then the movable handle is pressed down, so that the fixed ring is stably fastened inside the fixed buckle plate. The corresponding fixed rod a5 and the rear frame 11 are both fixed with locking rings that pass through the movable handle. The locking rings have keyholes, which can be used to fix external locks inside the locking rings, thereby restricting the position of the movable handle and preventing the movable handle from moving and causing the fixed ring to fall out of the fixed buckle plate. The movable handle is divided into a movable area and a non-movable area. The non-movable area is connected to the fixed rod a5 and the rear frame 11. When the movable handle is moved, the movable area of ​​the movable handle rotates along with the fixed ring. A spring is set between the movable area and the non-movable area. When the movable handle is pressed down, the spring is tightened, so that the fixed ring is fastened inside the fixed buckle plate. When the movable handle is lifted up, the spring is released, so that the fixed ring can move.

[0052] The implementation principle of this embodiment is as follows: When fixing the motorcycle to the back of the RV, firstly, remove the guide rail 12 from the keel 18 and take it off. Place one end of the guide rail 12 on one end of the fixed rail 13, and the other end on the ground. Then, push the motorcycle from the guide rail 12 onto the fixed rail 13. Next, adjust the position of the limiting rod 6, placing it horizontally on the upper side of the motorcycle footrest. Fix both ends of the limiting rod 6 with the fixing buckle a4 and the adjusting bolt 7, respectively. Then, put the guide rail 12 back in its original position and fix it. When it is necessary to open the rear door, it can be pushed... Under the constraint of the fixed axle 20, the front frame 1 and the rear frame 11 move with the opening angle of the rear door. The rear door can be opened and closed normally without removing the motorcycle. When the rear door is opened, the support leg 15 can be lowered and the lower end of the transfer wheel 17 can be kept in contact with the ground. After the rear door is opened, when the frame moves, the support of the transfer wheel 17 and the support leg 15 can reduce the impact of the motorcycle and frame weight on the position of the fixed axle 20, thus ensuring the long-term use of the fixed axle 20. When the rear door is closed, the support rod 31 can be attached to the lower end of the rear frame 11 to support the position of the frame.
