[0017] 1. This invention, through the installation of a vehicle body, roof, roof rod, roof rod switch, vertical tube, T-joint tube, and rivets, allows the folding vehicle to be in a folded state. When the folding vehicle is unfolded, the front and rear frames are pulled outwards, causing them to unfold under force. The first, second, and third side tubes transition from a folded state to an unfolded state, with the first side tube now horizontal. The two bottom frames also transition from a folded state to an unfolded horizontal state, with the bottom frames providing support at the bottom of the vehicle body. The operation is convenient and quick. The snap-fit ​​sleeve is then placed... The top of the connection between the two second side tubes locks the positions of the first, second, and third side tubes, thus locking the vehicle body. Pressing the roof rod switch and then pulling the roof rod upwards causes it to pass through the vertical tube and the roof rod switch. When the roof rod reaches its highest point, the roof rod switch locks it, providing support for the roof, which is positioned above the vehicle body. Pressing the small frame switch and adjusting its angle, then pressing the push handle opens... Close the door, then adjust the angle of the push handle to separate the handle from the clip, open the clamp, pull the handle outward, and adjust the length of the handle. The distance between the support frame and the first support rod is adjustable, thus adjusting the length of the handle. After adjusting the length of the handle to the appropriate level, close the clamp, which will lock the support frame and the first support rod, completing the adjustment of the handle length. At this point, the folding bike has been fully unfolded. During the folding and unfolding process, the first and second side tubes rotate along the rivets on the three-way tube, effectively ensuring the safety and stability of the first and second side tubes during folding, thereby enhancing the ease of operation of the first and second side tubes during folding. In this invention, the first and second side tubes are connected to one side wall of the front and rear frame vertical tubes by rivets, and the connection between the front and rear frame vertical tubes is set as a three-way structure. The roof rod is located in the hollow of the front and rear vertical tubes and moves up and down. Compared with previous folding bikes, the roof rod does not need to be stored separately and does not occupy any space after the bike is folded. The independent push handle and small frame can be selected separately.

[0018] 2、The second opening of the outer wall of the ceiling rod is aligned with the trapezoidal strip, the trapezoidal strip is inserted into the movable cavity of the ceiling rod through the second opening, in the process of inserting the trapezoidal strip into the movable cavity, the trapezoidal strip is inserted into the trapezoidal slot of the supporting strip, the deeper the trapezoidal strip is inserted, the deeper the trapezoidal strip is inserted into the trapezoidal slot, the trapezoidal strip and the trapezoidal slot are in contact and abut to upwardly top the supporting strip, the second spring is elongated, the supporting strip upwardly tops the top rod, the top rod is in contact with the bottom of the auxiliary sleeve through the first opening, the top rod upwardly tops the auxiliary sleeve, the bottom of the auxiliary sleeve pulls the flexible sleeve upwardly from the middle of the flexible sleeve, the middle of the flexible sleeve is pulled upwardly and outwardly under stress, the bottom of the flexible sleeve is inwardly folded while moving upwardly under stress, and the bottom of the flexible sleeve clamps the outer wall of the ceiling rod, so that the safety and stability of the connection between the ceiling and the ceiling rod can be effectively improved; when the ceiling needs to be removed, the button is pressed, the arc-shaped strip is outwardly topped by the button, the first spring is compressed, the trapezoidal strip moves along the arc-shaped strip, the trapezoidal strip is pulled out from the trapezoidal slot, the supporting strip loses the supporting force, the second spring is contracted to pull the supporting strip downwardly, the supporting strip drives the top rod to move downwardly, the top rod is contracted to the inside of the ceiling rod through the first opening, the auxiliary sleeve loses the clamping force, the auxiliary sleeve is reset downwardly, the auxiliary sleeve drives the flexible sleeve to be reset, the bottom of the flexible sleeve is separated from the outer wall of the ceiling rod, then the ceiling is lifted upwardly, the connection sleeve and the ceiling rod are separated, and then the ceiling and the ceiling rod are separated, so that the operation is convenient and fast.
