A scanning module for a distance measuring device, comprising:

• a main body holder defining an accommodation cavity;
• a first optical assembly within the accommodation cavity and attached to the main body holder;
• a first drive assembly connected to the first optical assembly to drive the first optical assembly to move relative to the main body holder;
• a second optical assembly disposed at one end of the main body holder;
• and a second drive assembly on a side of the second optical assembly adjacent to the main body holder and connected to the second optical assembly to drive the second optical assembly to move relative to the main body holder, wherein the second optical assembly and the first optical assembly defines a light transmission channel, and at least one of the first drive assembly or the second drive assembly is disposed outside the light transmission channel.
