[0002] A tricycle is a means of transportation transformed from a bicycle, which can carry people or goods. It was very popular after the 1930s and gradually replaced the rickshaw. A tricycle is a combination of a rickshaw and a bicycle. Tricycles can be divided into manual tricycles, electric tricycles, children's tricycles, battery tricycles, etc.

[0003] The publication number (CN212946502U) discloses a rectangular tube bending and punching integrated machine for electric tricycle production. After the preparation work is completed, the third hydraulic cylinder is started. The third hydraulic cylinder operates to bend the rectangular tube at a certain angle. At this time, the third hydraulic cylinder resets, the first L-shaped push plate disengages from the fixation of the rectangular tube, the third hydraulic cylinder drives the turntable to reset, the first hydraulic cylinder is started, the first hydraulic cylinder pushes the first mounting seat forward by a certain distance and then stops, the second hydraulic cylinder is started, the second hydraulic cylinder pushes the second mounting seat to move left by a certain distance and then stops. At this time, the stepping motor is started, and the stepping motor drives the rectangular tube to rotate 180 degrees and then stops. Repeat the above steps again to perform bending and forming processing on the second bending part of the rectangular tube. The above device uses a complex method to drill and bend the rectangular tube, which will result in relatively low processing efficiency and needs to be improved. Content of the Utility Model
