Description

Technical Field

[0001] The utility model relates to the field of self-assembly, in particular to a foldable flexible clamp bicycle assembly frame. Background Art

[0002] As we all know, a bicycle is assembled from multiple structures, including a frame, a front fork, a rear fork, etc., and the main components are assembled from multiple parts. Whether it is the installation of the whole vehicle or the installation of each part of the main components, it is necessary to fix the whole frame or the main body before assembling other parts. Therefore, it is necessary to use a bicycle assembly stand to fix the whole vehicle or the main components. The traditional bicycle assembly stand has the following problems: 1. It adopts an ordinary rigid clamping and fixing method. For ordinary aluminum alloy frames, it is not easy to be damaged due to their own strength problems, but carbon fiber frames are very easy to cause the upper tube of the frame to break due to poor force control; 2. Manually control the lifting and lowering of the bicycle assembly stand. If the whole vehicle is clamped, it will make the lifting and lowering bulky and not easy to lift in place.
