Abstract: A grip structure includes a grip base and a grip mounted with or dismounted from the grip base along a first direction. When being disposed on the grip base, the grip can be applied with an external force to move together with the grip base along a second direction non-parallel to the first direction. The grip has a finger abutting portion formed on the circumferential surface of the grip along the first direction for the fingers of the user to be abutted thereon. Therefore, the grip is changeable in the direction relative to the grip base according to the dominant hand of the user in a way that the finger abutting portion is toward the left side of the grip base for the right-handed user and toward the right side of the grip base for the left-handed user, thereby improved in the convenience of usage and hand feel.
