The invention relates to a deep laser hole linearity detecting device having a rotation preventing mechanism. On the basis of the laser alignment principle, a linearity error of an axis of a workpiece hole of a deep hole is measured by using a PSD sensor. A measured workpiece is placed at V-shaped blocks fixed at a detection rack. The PSD sensor is fixed at a measuring head; the measuring head is pulled by a measuring rod to move the PSD sensor from one end of the deep hole to the other end of the deep hole. The measuring rod is a rigid part and multiple segments of the measuring rod are connected to connect the measuring head. In order to prevent rotation of the measuring head around the axis of the deep hole, the measuring rod has a non-circular cross section to realize cooperation with a hole or groove of the detection rack. The measuring rod is connected with the measuring head by a cardan joint to have three translation freedom degrees and have no rotation freedom degree. Detection information is transmitted to the outside of the deep hole by an antenna and the transmitted information is received by a computer. The detecting device has small occupation space; a detection error caused by rotation of the measuring head is eliminated; the antenna extends out of the hole to avoid signal shielding; and the detection precision is high.
