Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0010] Such as figure 1 and 2 The shown tool change wrench for gear shaving machine includes a handle 3 and a ferrule 2, one end of the handle 3 is fixedly connected with the ferrule 2, and the inner surface of the ferrule 2 is provided with a protrusion 21 that cooperates with the outer peripheral surface of the nut. When the nut 1 is a slotted nut, there are several protrusions 21 corresponding to the positions and numbers of the slots on the slotted nut. The nut 1 can be tightened or loosened by turning the handle 3, which is easy to operate and highly practical.

[0011] The device can be loosened directly, and the slotted nut of the cutter head can be tightened.

[0012] The above is only a preferred embodim...
