[0003] However, existing bicycle projection computers are fixed to the bicycle handlebars and their angle cannot be adjusted. When riding with an upright posture or standing, the angle of the bicycle projection computer is not easy to observe. Therefore, there is a need for a bicycle projection computer that can be adjusted on the bicycle handlebars. At the same time, the bicycle projection computer needs to be securely clamped to prevent it from falling off during rides.

[0004] Therefore, we need a bicycle projection speedometer angle adjustment mechanism to solve the problem of fixed installation of existing bicycle projection speedometers and to realize the adjustment of the bicycle projection speedometer angle. Utility Model Content
