Meter lathe clamping device

The utility model discloses an instrument lathe clamping device, which relates to the field of instrument lathes and comprises a lathe base, one end of the lathe base is provided with an axial adjusting handle, and the axial adjusting handle comprises a turntable shell, a screw rod, a damping rotating shaft, a tooth column, a handle body, a rotating shaft and a rotating handle. The damping rotating shaft matched with the lathe base is rotationally connected into the rotating disc shell. The handle body is rotated to drive the rotary disc shell and the damping rotating shaft to rotate, then the connecting rod is driven to adjust the position of the horizontal adjusting table and the position of the axial adjusting table, when the general position is moved completely and small feed amount is left, the rotary handle is rotated, and due to the fact that the resistance of damping in the damping rotating shaft is large, the feed amount is large. When the handle body is not pushed, the resistance of the handle body
