Detailed ways

The gear type lathe tool holder of the present invention will be further described in detail below in conjunction with the accompanying drawings.

The gear-type lathe tool holder shown in Figure 1 and Figure 2 includes a central shaft 16 provided with a handle 10, a driving wheel 1 fixed on a slide plate 19 in the lathe, and a driven wheel 2 matched thereto. A protective cover 15 is provided; the center of the driving wheel 1 is fixed with a rocker 3; the top of the driven wheel 2 is fixed with an I-shaped cutter head 5 through a screw 14, and the I-shaped cutter head 5 is connected to the center of the driven wheel 2 and the middle slide plate 19 are all provided with the hole that matches with central shaft 16, and wherein, I-type cutter head 5 and driven wheel 2 rotate relative to central shaft 16, and slide plate 19 is connected with central shaft 16 by screw thread 11 in lathe; The center of 5 is fixed with angle dial 6 by screw, and the minimum scale value of angle dial 6 is 10 °; There is a screw rod 9 threaded with it; one side of the straight hole 18 is provided with a scale 17, and the range of the scale 17 is 25cm, and the corresponding scale 17 on the I-shaped cutter head 5 is provided with an arc hole 8, the arc A screw rod 9 threadedly connected with the hole 8 is provided.
