[0003] Most turntables on the market are currently bulky and not flexible or convenient to use, or their positioning accuracy is not high with each rotation, which affects the overall scanning accuracy and results in inaccurate 3D data of the scanned object. To solve the above problems, a single-axis automatic turntable for scanning is proposed. Utility Model Content

[0008] The beneficial effects of this utility model are:

[0009] This utility model, through a reasonable internal structure design, compresses space to the extreme while ensuring normal operation, making it more flexible and convenient to use; it adopts a stepper motor to ensure torque output, making the entire motion structure more stable; and it uses a combination of a stepper motor and a synchronous wheel motion structure to greatly ensure the positioning accuracy of rotation.
