The invention discloses a reamer device for machining a valve retainer and a valve guide pipe. The reamer device comprises a reamer handle (5), a blade arranged on the reamer handle (5) and used for machining the valve retainer, a connecting rod (1) fixedly connected with the reamer handle (5) and a reamer (6) fixed on the top end of the connecting rod (1) and used for machining the valve guide pipe. Machining rotation centers of the blade and the reamer (6) are coaxial. Due to the fact that the reamer device is provided with the blade and the reamer, in a machining process, the blade machines the valve retainer in a rotation mode, and meanwhile the reamer machines the valve guide pipe in a rotation mode. Therefore, the valve retainer and the valve guide pipe are machined simultaneously, and time and labor are saved compared with machining of the valve retainer and the valve guide pipe respectively. In addition, the reamer handle and the connecting rod which are fixedly connected drive the blade and the reamer to rotate simultaneously, the coaxiality of rotation circumferences of the blade and the reamer is higher, and the coaxiality of the machined valve retainer and the valve guide pipe is higher.
