摘要：
A test device and a rotation module thereof are provided. The rotation module includes a rotation body and a sleeve. The rotation body includes a shaft, a first tube element, and a second tube element. The shaft is pivoted in the housing, and has an annular protrusion. The first tube element and the second tube element are sleeved on the shaft respectively, and the second tube element is located between the first tube element and the annular protrusion. The sleeve is slidably disposed on the rotation body. When the sleeve moves between a first position and a second position back and forth, the second tube element is driven to rotate back and forth relative to the first tube element. The annular protrusion is respectively driven by second tube element and the sleeve drive the annular protrusion so that the shaft rotates relative to the first tube element.
