Detailed ways

Referring to Fig. 1, in the embodiment, the respective upper ends of the front frame 1 and the rear frame 5 are horizontally connected together, and each side of the front frame 1 and the rear frame 5 is one narrow at the top and wide at the bottom or two upper ends connected to each other. Together erect rigid material constitutes, and the lower end of each side of front vehicle frame 1, rear vehicle frame 5 is connected on the support frame 9, and support frame 9 is provided with movable link 10, and this movable link 10 can support frame 9 and the two sections of the folding bottom tamarisk 11 are connected into one body, and the two sections of the folding bottom tamarisk 11 can be stretched flat into a straight line, and can also be folded closer. Through the action of the movable connector, the front frame 1 and the rear frame 5 can be reached. The purpose effect of both folding and stretching is that the bottom ends of the front frame 1 and the rear frame 5 are connected with the support frame 9 and the wheels 12; Handlebars and other devices are provided with a backrest 6, a foldable seat 7, and a rear cross 8 on the rear frame 5. The foldable seat 7 can be expanded to be perpendicular to the rear frame 5, and can overlap with the backrest 6 when folded. One end of the connecting belt 2 is connected on the softly connected vehicle seat 4, the adjusting device 3 can be set on the connecting belt 2, the other end of the connecting belt 2 is connected with the front frame 1, the rear frame 5, the rear cross tamarisk 8, and the connecting belt 2. It can be detached from the front frame 1. For the convenience of use, devices such as handlebars and brakes can be installed on the front frame 1. For the safety of the passengers, it can be installed on both sides of the front frame 1 and the rear frame 5. defensive equipment.

The above-mentioned foldable trolley, when in use, the person unfolds the front frame 1 and the rear frame 5, so that the two sections of the folded bottom are in a straight line, and they sit on the softly connected vehicle seat connected by the connecting belt 2. 4, also can ride on the folded car seat 7 that opens, lean on the backrest 6 to have a rest, also can all sit people on two seats, promote by the personnel of the back, also can open the connecting band 2 that is connected to front vehicle frame Sitting alone on the soft connection car seat 4, fasten the connection belt 2 for leg strength exercises, the adjustment device 3 can adjust the length of the connection belt 2, and the folding bottom 11 can be stretched and folded.
