Abstract
The present application relates to woodworking tools in general and in particular to a woodworking grooving planer. A woodworking grooving planer comprises a planer body, a planer cutter assembly, a planer cutter lifter, an axial locking mechanism and a radial locking mechanism; the grooving planer lift comprises a rotary leadscrew, a lifting slider, a lifting base, a guide rod and a stopper; rotating the rotatory handle can make the lifting slider drive the cutter assembly to move up or down; the axial locking mechanism and the radial locking mechanism can make the rotary screw thread press the lifting slider axially and radially, so that a close thread fit is established between the rotary screw and the lifting slider, thus effectively avoiding the problem of instability and imprecision caused by pitch clearance.

A woodworking grooving planer, comprising:
- a planer body, provided with a handle, a planing groove and a planing surface;
- wherein the planing groove penetrates through the planer body and opens on the planing surface;
- a grooving cutter assembly, comprising a grooving cutter and a cutter shaft;
- wherein the grooving cutter and the cutter shaft are integrally formed or fixedly connected;
- a cutter lifter, comprising a rotary leadscrew and a lifting slider;
- wherein the rotary leadscrew is rotatably arranged on the planer body, and the lifting slider is arranged on the rotary leadscrew through a threaded connection;
- when the rotary leadscrew rotates, it drives the lifting slider to move up or down;
- and the grooving cutter assembly is fixed to the lifting slider and moves up or down synchronously with the lifting slider to adjust a working depth;
- an axial locking mechanism, configured for locking the threaded connection between the rotary leadscrew and the lifting slider from an axial direction of the rotary leadscrew;
- and
- a radial locking mechanism, configured for locking the threaded connection between the rotary leadscrew and the lifting slider from a radial direction of the rotary leadscrew, and also configured for locking a rotatable connection between the rotary leadscrew and the planer body;
- wherein the cutter lifter further comprises a lifting base, a guide rod, and a stopper;
- the lifting base is fixedly arranged on the planer body, one end of the guide rod is fixedly arranged on the lifting base, and the stopper is fixedly arranged on the guide rod at one end opposite to the lifting base;
- and
- wherein the rotary leadscrew is rotatably arranged on the lifting base and the stopper, and the lifting slider is located between the lifting base and the stopper.
