[0030] In this embodiment, during the lifting and lowering process of the top clamping ring 13, the top clamping ring 13 and the bottom clamping ring 12 can be controlled to separate or combine. When the top clamping ring 13 and the bottom clamping ring 12 are combined, the fourth gear 11 can be prevented from continuing to rotate. It is flexible and practical, has a good limiting effect, and has high stability.

[0031] Example 3, refer to Figure 2 A double worm gear workbench for a gear milling machine, a first hydraulic lifting bin 16 is arranged at the bottom of the inner wall of a machine base 1, and a first oil supply channel 17 and a first oil discharge channel 18 are respectively opened on both sides of the inner wall of the first hydraulic lifting bin 16, a second hydraulic lifting bin 19 is arranged on one side of the inner wall of the machine base 1, and a second oil supply channel 20 and a second oil discharge channel 21 are respectively opened on the inner wall of the second hydraulic lifting bin 19.
