The support sleeve 2 is inserted with a knife shaft 3 which can rotate therein, namely a bearing 31 is arranged between the knife shaft 3 and the support sleeve 2, so that the knife shaft 3 can rotate at high speed in the support sleeve 2. And a first limit structure capable of preventing the support sleeve 2 and the cutter shaft 3 from moving relatively along the length direction is arranged between the support sleeve 2 and the cutter shaft 3, namely, the support sleeve 2 can drive the cutter shaft 3 to move synchronously when moving, so that the control of the support sleeve 2 to move along the length direction is equivalent to the control of the feeding amount of the cutter shaft 3. The base 1 is further provided with an adjusting rod 4 which can rotate and drive the supporting sleeve 2 to move along the length direction, and at least one group of reduction gear sets connected with the adjusting rod 4 and the supporting sleeve 2 is arranged between the adjusting rod 4 and the supporting sleeve 2.

In the utility model, the cutter shaft 3 is used for clamping cutters such as a cutter and a hemmer, and the cutter shaft 3 rotates at high speed in the working process, so that the feed amount of the cutter shaft 3 can be precisely adjusted when the cutter shaft 3 rotates at high speed. When the adjusting rod 4 rotates, the supporting sleeve 2 is driven by the reduction gear set to move along the length direction of the mounting hole, and then the cutter shaft 3 is driven to feed. The reduction gear set is formed by a little big gear, and reduction gear set can come the underspin with certain number of teeth proportion, adjusts pole 4 like this and rotates several rings, supports cover 2 and just can remove very little one section distance, just also the arbor 3 just feeds a bit, like this, just can realize the accurate fine setting to the arbor 3 feed volume through rotating adjusting pole 4.
