By the way, the general carrying frame is mainly combined with the car to fix the bicycle. The known carrying frames are mainly divided into two types: the roof type and the rear type. The roof type is set on the roof of the car. Because this structure is more difficult in the process of fixing the bicycle and removing the bicycle, and it is difficult to carry the bicycle. Finally, its overall vehicle height is too high, and it is easily affected by the height limit when traveling, so it is less popular with ordinary people. The main structure of the rear type is composed of a fixed piece combined with the rear end of the car, a pivoting piece pivotally connected with the fixed piece, and a bearing piece combined on the pivoting piece for carrying the bicycle. The rotating part can be pivoted and positioned between an upright position and a flat position. When it is in the upright position, the length of the protrusion can be reduced to maintain the safety of the car when it is running. When it is in the flat position, it can be used for carrying bike.

However, a general rear-type car frame will be provided with a control piece, and the control piece is located near the pivotal joint between the pivoting piece and the fixing piece, but the user must hold the handle when operating the pivoting piece to pivot.
